Gone But Not Forgotten


Midwest Hots II (40 size): Read the "From The Shop" column in the May 1997 RCM for a an interesting perspective on flying in other countries. The letter is from Rick Shook when he was flying in Egypt. Rick and I were flying together at Wright-Patterson AFB and would dogfight on numerous occasions. One day in 1992 we went up for a some ribbon cutting fun and both planes came down in little pieces - we both zigged when one of us should have zagged. We looked at each other in shock and commenced to laugh, along with everyone else at the field. We shook hands and walked out to pick up the pieces.  FLOWN - CRASHED


Midwest Super Hots (60 size):  This plane had been flying non-stop for 13 years for me since I bought it, from someone who had also been flying it for a while.  I took it to the field every time I flew and had been looking for an excuse to tear it apart, rebuild it and recover it.  The engine died directly overhead at about 30 feet and I had to land long.  Long on this field meant landing between two trees and a metal signpost.  I missed the signpost and hit the trunk of the center maple tree about 6 feet off the ground, dead on with the spinner.  It made a nice little hole in the tree.  The plane dropped straight down and the body broke in half.  The wing is fine.   I could glue it right back together and fiberglass the joint.  Instead, I have built a new lightweight body and copy the whole thing so I have a backup-up Hots.  FLOWN - CRASHED

   


Tiporare : I truly still don't know what happened with this plane. I had been flying it for almost two years when it decided to call it quits. One day I took off, raised the gear, turned downwind, and then ..... nothing. It just kept flying at full throttle as it slowly rolled over and headed straight down. I killed the throttle and even turned the transmitter off and on. Nothing. It hit pointed straight down going at least 120 MPH. It made a respectable hole in the ground. The engine was buried a foot deep in dirt. The wing looks OK, but look again. It was a foam-core wing and was compressed chord-wise. It was unsalvageable. But the horizontal stab lives on in the ~Ultra Sport / Tiporare II. Post crash autopsy showed all connections to be intact and the battery to be well in the green. FLOWN - CRASHED


P-38/P-61/F-82/OV-10 Wanna-Be : This self-designed plane flew great for two years until I decided to get creative. I moved the engine to the back of the main body and added a nose cone with weights where the engine had been. I thought I had the CG correct. Nope. It was way too far back. The plane got to about 10 feet altitude while doing a great saber dance. It oscillated back and forth several times before deciding to head back to terra - firma. In this instance, terra - firma was blacktop and none too forgiving. The wingtips survived FLOWN - CRASHED


Conniption I/Conniption II : I designed and built this aerobatic plane and used the landing gear and engine from the crashed Hots II. The plane was a great success. It flew for over three years until I tried a Lomcevak about 40 feet off the ground. It did the maneuver fine, but I fumble - fingered it and smacked it into the desert. I took the pieces of that crash and built the Conniption II. It was the same design with a few minor changes. The wing center section was beefed up and the barn-door ailerons were integrated into the wing structure. This plane could do everything that its daddy could do, plus fly a lot faster. Unfortunately, the second weekend I took it out to fly, I smeared it all over the desert in about the same spot its papa had bought the farm. I was doing a series of snap rolls going upwards when the hatch lock came undone and the receiver battery went ballistic. I found the battery pack 150 feet from the crash site. The plane just kept snapping in a nice arch. My kids thought it made a very nice mess on the desert floor.  The same landing gear and engine live on in the Conniption III, which I have been flying since 2002.  FLOWN - CRASHED

This story and picture won the "How mangled did you go?" contest at RCUniverse, for which I won a Fliton Flubber.


Javelin (sorta): Built from RCM plans to match a small foam-core wing I had.  My version has a longer body length -to- wingspan ratio than the plans, and the wingspan is smaller.  I finally got this plane in the air with a long run down the runway.  It just did not have enough wing area for its weight. After several circuits of the field, during which I discovered that the max speed was about 2 mph faster that the stall speed, I decided to land.  As I brought the engine back, it died and the plane dropped like a brick.  At 45 degrees nose down, no amount of elevator would slow the descent.  It hit soft sod and the damage could probaby have been repaired in less than an hour, but the flight characteristics don't merit a rebuild.  FLOWN - CRASHED


Sorta-Scale Northrop N9M Flying Wing : Built from my own plans, it has the same general planform as the N9M. It was built as a proof of concept (1/2 scale) airframe for my UAV flying wing project.  I had been flying it for a while, but something happened during its second flight of this particular day.  The plane was rock steady, but as it was moving away it started to pitch down.  I added back elevator and it pulled back up, but continued to pitch over.  I continued to add back elevator as it continued to pitch nose down.  It about 10 seconds I reached full up elevator and I could add no more.  It was almost as if the elevator center point was moving in one direction.  I had complete control over engine and ailerons : during those 10 seconds I had managed to turn the plane around and was aiming for an empty field (as I added up elevator).  I thought I had it made.  Not quite.  It hit the top of the last tree before the field and shredded itself.  There was a cloud of leaves and balsa as it acted as a tree trimmer.  It finally came to rest about 30 feet off the ground.  The battery power was on for the 1.5 hours it took me to go home and get some long poles.  After getting it down and arranging the pieces, the receiver and servos worked fine.   Even the main gear retracts still function fine too.  The elevon servos are centered where they should be.  I don't mind crashes when I learn something, but this is annoying because I have no idea what happened.   FLOWN - CRASHED

Vundango : This plane went through two forms before I found the version that flew well.  The second picture shows the version that flew very well.   It had a Speed 400, 2.5:1 gearbox, 12 amp ESC, R-4P rx, and the controls were mixed ailerons and elerudders via electric elevon mixing and mechinal mixing.  It was large version of the Tiny.  I was showing off and flying low around some trees in my front yard.  It got behind one set of trees and I lost sight of it.  Next thing I knew it was on the driveway, with all the internal structure of the wings smashed to bits.   The only thing holding it together was the Monokote.  The motor, gearbox, and ESC were moved to a two meter electric flying wing camera ship for my Aiptek Pencam SD.    FLOWN - CRASHED












 

Kingbergh Wing x2 : I had been flying my 11' Klingberg Flying Wing for over 20 years with an OS 61 for power.  This was built from Klingberg plans blown up twice. It was originally powered by OS 61 engine, but I had also flown this powered by a TowerPro 3520 outrunner and 50 amp ESC, both in tractor and pusher configurations.  It was 11 pounds total weight and had mechanical retracts, controlled by seven channels [elevons(2), throttle(ESC), mechanical retracts(1), nose steering(1), split-opening drag rudders(2)].

In 2012 I removed the engine and stripped the covering.  I installed several hundred LEDs on the framework and recovered it with clear Monokote, and I also installed a 60 size outrunner electric motor and 70 amp ESC.  Along with several other planes, I took it to the Southeast Electric Flying Festival (SEFF) in Americus, Georgia. This was the second time I had visited SEFF, but I did not have any planes on my first visit, so I was looking forward to flying at SEFF.  It is a great fly-in with lots of fun.  The night bowling is particularly fun to watch, or participate if you have the right throw-away plane.

On the first flight the plane completely locked up about 3 minutes into the flight and was totally demolished.  The plane was straight in front of me, less than 200 ft away, turning to crosswind. I shouted 'LOCKUP' and people dove for cover.  It came down on the field, in front of the pits.  Based on my discussions with other people at that SEFF who had similar problems and lockups, we came to the conclusion that DSM2 was the most likely culprit for the lockup.  SEFF had rules in place that your radio should only be turned on if you were at a flying station, of which there were less than 50 total flying stations for the entire field. That may sound like a lot, but there were over 1000 registered pilots, and there only 80 available slots in the 2.4 Ghz spectrum.  I had a solid link, and did a range check before I took off.  All it took was for enough people back in the all the RVs to turn on their transmitters, resulting in a completely saturated spectrum.  DSM2 will look for open slots, and then transmit when it believes it has found an empty slot. Since it does not hop, with every slot full, there will eventually be problems. After this, I restricted myself to only use DSM2 at my home field with < 10 active pilots, or at places where other flyers are not around at all.  At any big events with lots of flyers, I will only use DSMX, which has never given me any problems at SEFF or Joe Nall.  FLOWN - CRASHED 


Fun-Fly :  I took the wingtip plug-ins (2 feet each) from the crashed plane above and joined them to make this fun-fly plane, complete with carbon fiber tail boom.  OS 40, 4 channels [ailerons(2), elevator(1), rudder(1), throttle(1)] SOLD

draganfly_iii_tn.jpg (2272 bytes)


Draganfly - This indoor and outdoor flying four bladed electric helicopter is controlled completely by the on-board computer that mixes the four input channels with three axis gyro inputs, and adjusts the motors:  2 motors go clockwise, 2 go counter-clockwise.  I have upgraded my original -II to the pictured -IV configuration with a carbon-fiber airframe, a micro receiver, a micro- television camera that allows airborne video, and Thunder Power 3S lithium polymer batteries.  Video from my front yard.  Four channels [no servos - all electronically mixed] SOLD

I have also built a PIC-based board to read the PPM inputs to the FETS controlling the motors on the stock Draganfly flight controller board. The PICS convert the 0 - 5.8 ms PPM pulse to 1 - 2 ms PWM pulses, suitable for use with a brushless ESC.  Schematics and programming data for the PIC can be found on this page.








Tricopter - SOLD
I flew this tricopter with 2410-09 motors for several years. I have moved the electronics to a new V-Tail Quad, along with an extra 2410-09 motor and ESC.

Flip FPV Quadcopter - SOLD
I bought this at a swap meet with a DJI Naza-M controller installed. I added LEDs all around and flew it like that for a while, then decided to move the motors and speed controls to other quads.


SIG Four Star 40: This was repaired from a crashed Four Star 40 body found in the trash at the field.  The wing came from the X-29 Canard. Anakin Skywalker is the pilot. This plane was removed from the hangar at the Shadow UAV flightline on Ft Huachuca and never returned.  ASP 61, four channels [ ailerons(1), elevator(1), rudder(1), throttle(1) ]   Missing In Action - Sierra Vista, AZ

shockflyer_tn.jpg (3473 bytes)

ICARUS Shockflyer - Park and indoor 3-D airplane. This plane was so beat up it was time to retire it.  The Himax HC2812-1080, 17 amp brushless ESC, GWS R-4P receiver (w/ channel 6 added) were removed to go on another plane,  five channels [ailerons(1), VPP(1), elevator (1), rudder (1), throttle (ESC)]  FLOWN - retired


Camera Plane #1 : The original fuselage was thrown away.  The wings and tail live on in the new, improved Camera Plane #2.  The two elerudders were secured by nylon screws and were removable for travel.  20x40 brushless inrunner, 6:1 gearbox, 18 amp ESC, four channels [elerudders(2), throttle(ESC), shutter]  FLOWN - retired

foamy_ultimate_tn.jpg (3188 bytes)


Foamy Ultimate : Built from plans available for free at JetWorksModels, made out of Bluecor foam. Hint: Increase the aileron size. Also, the CG in the plans works fine for normal flight, but does not work for 3-D. Move the CG back about one inch for 3-D flying. 2408-21 outrunner and 18 amp ESC, four channels [ailerons(1), elevator(1), rudder(1), throttle (ESC)]  FLOWN - retired

I cut out eight of these things and gave the other seven away to friends who fly RC.  I eventually gave the eighth copy to a friend.

slow_stick_ii_tn.jpg (3438 bytes)


Slow Stick II : I resurrected my original Slow Stick wing and fuselage, and added a V-tail and LEDs for night flying. Check out this page to see the LEDs and how to set up LEDs .   There were a total of 46 super bright LEDs on the plane; 20 blue + 6 red + 6 green on the wings, 8 blue + 6 white on the tail.  TP 2410-12Y, 18 amp ESC, three channels [elerudders(2), throttle (ESC)]   The LEDs were moved to my other night flyer, the UFO.  FLOWN - retired



VFO VTOL: Copied from pictures of the ElectriFly VFO.  This uses the same mixing as my NightOwls, minus the second motor.  2410-09 outrunner and 18 amp ESC, and four HXT500 servos.  Five channels [ elevons(2), rudder1(1), rudder2(1), ESC ] FLOWN - retired


F-27 Thrust Vectored Stryker: EPP foam. The motor had a 2-D thrust vectoring system. Motor pitch was driven by the elevator, and motor yaw wasdriven by rudder.  These mixes could be activated by a single switch, so the plane was launched with normal controls and then the motor 2-D vectoring was turned on at a safe height.  The plane would spin like a top with full yaw commanded.  It was powered by a rewound KD A22-20L outrunner brushless motor and a folding 9x6 prop with a homemade hub. Five channels [ elevons(2), motor tilt (1), motor yaw(1), throttle(esc) ]  FLOWN - retired
zagi_tn.jpg (2269 bytes)

Zagi : EPP foam, 2408-21 and 18 amp ESC, three channels [ elevons(2), throttle(ESC) ] FLOWN - retired


Camera Plane #2: I took the wing, empennage, motor, and speed control from my original camera plane #1 above and built this new version.  It uses twin booms so it has a much stiffer tail assembly, and it has room for a digital video camera looking out the nose, and a digital still camera looking out either side under the wing.  The whole thing comes apart into small pieces to fit in small box for traveling, and the full foam fuselage protects the camera much better than my old camera plane. Four channels [ elerudder(2), throttle(ESC), shutter] FLOWN - retired

Tricopters versions 1 and 2 - The first two multicopters I built were TriCopters with four HK 401B gyros each.  These were made before multi-copter controllers became readily available, and we used CCPM helicopter mixing in computer radios to control the motors through gyros on each arm.  FLOWN - retired

The larger Tricopter was powered by three TowerPro 3520 outrunners and 50 amp ESCs, and the smaller Tricopter was powered by three 2410-09 outrunners and 18 amp ESCs. The top picture shows the small TriCopter with its carbon fiber body and booms.  They both used four gyros and identical mixing, with slightly different gains on the gyros and exponential settings. 
Check out this page for full details on the gyro setups and radio mixing that were used with independent gyros.
