Let's see, it's been a while since updating my Blog.

Planes...lost the Sea Vixen to what I thought was a radio signal loss but I think now it was a battery cable problem. Had the same problem with a new F-86 after only 15 or so flights..it just lost signal and had no control whatsoever, just like the Vixen. The only way I could see that is with a power outage. I'm not the best solder person and both were cramped in the cockpit and it explains both. Both planes had at least 5 seconds of fight before crashing so I think if it were a signal problem that they would have recovered. Both of those planes also had one antenna wire outside of the airframe as an extra measure of security.

Thanks to RCGroups discussions I have found one of the greatest little inventions for RC failsafe...a Scorpion Battery Backup that consists of a 2-cell lipo with a 10 amp BEC built into it. It only comes on when RX power falls below 4.99 volts. It can also be ported from plane to plane easily. It's about the size of a big UBEC so I am replacing all heavy ESC/UBEC combinations with cheaper, lighter models to save weight since the Battery Backup performs that function.

I tested it by unplugging the main battery and the motor shut down but all other flight surfaces continued to work for several minutes...more than enough to get the model to the ground safely.

Here is the link...

Now for the other change...I found an awesome new Transmitter...
FrSky Taranis !!!

It is 2.4 ghz and has great frequency hopping/hunting electronics that combine the best of Futaba/JR electronics plus it talks to you! It is also almost infinitely customizable with many switches and rotary knobs and sliders. The RX's are cheap and the TX is only about $180. It has full telemetry built in and had many sensors available for it. Starting Feb 2014, I'm converting my fleet.

16 channels and can be expanded to 32 with S-Bus and Smart Port technologies.

My new love is the Sea Vixen...a 1950's to early 60's British jet bomber.

It's my new favorite plane! I bought it as a kit and put a Cyclone Power IR550-2800kv-40 4S/5S motor with CP 10 blade fan. It flies well on 4S or 5S but the 5S makes it a screamer! It flies like a dream only exceeded by it's docile landing characteristics.

See video below...it was a gray, rainy day so video is not great...

The RC Lander Panther has been through trials and tribulations. The original Eflight BL-15 and HET 4 blade fan were adequate but not much low end power and not very fast on high end either.

Soooo...I put in 4S Cyclone Power 3300kv outrunner motor with Changesun 10 blade. It wasn't even enough power to get it off of the ground. So I changed power plant to Cyclone Power IR (inrunner) 550-2800-40 with Cyclone Power 10 blade fan. It's a 4S or 5S setup. On 4S it still wouldn't rotate. But on 5S it became a whole new plane. It lifted off long but good enough and was much faster and more responsive in the air.

In the meantime I also found out that I had balanced it WAY too nose heavy and this further reduced time to lift off !!!

On last flight this last week, I miscalculated wind and landed very heavily and cracked left wing almost in two. There was a crack on both sides of the wing up to the air intake. I used Gorilla Glue and some fiberglass planks to shore up the wing. I also had to glue the nose wheel platform that had loosened in the hard landing as well as the tip tank which came completely off.

Maiden next week.

5/18/13 - Maidened and everything was great. Now that CG is right and using
5S powerplant, it takes off very well in about 3/4 of the space as previously. She is much faster in the air and landings are softer since CG is further back. She does LOOK like she is flying a little tail heavy (nose up attitude) but nothing major and no problems on landing so I think it's about right.

New F9F-2 Panther is built and was test flown this last weekend. The top vent mods from the factory worked great, as did the factory installed electric retracts, lights and flaps. I installed all other servos with HK Turnigy Metal Gear 90's, except just used some old 9 gram servos for flaps.

The maiden was uneventful with just a few clicks of up elevator and a couple of clicks of right aileron and she was straight and level with hands off. The take off and landing were with full flaps. The take off took WAY too long to get off of the ground. The landing was slow, predictable and smooth. No ballooning at all with power down this time! The lights were visible but not great EXCEPT for the afterburner...you could really see that red ring brightly on fast passes and take off!

A flying buddy suggested at the field that smaller main gear wheels would bring the nose up for easier take offs. I replaced them with the next size smaller wheels from stock. We'll see how that works but it looks better already.

Re: Futaba 7C Transmitter

I sent the radio back for warranty work regarding the left pull on rudder when throttling up. The radio was in it's way back to me at the time of this writing. The technician at Futaba said that they replaced the Rudder/Throttle "pot" and rebooted software and it was working properly. I sent it for "expedited processing" which cost's about $40 with guaranteed 2-day turnaround. Best money I ever spent.

The RC Lander Blue Panther nosed in shortly after the video below. It was flying well and about halfway through the battery pack it was going away from me and lost all directional control even though the motor was still running. It was about 20 feet off of the ground and just nosed in and busted to pieces and lost battery. I was using Futaba 7 channel receiver. I blame it on HobbyKing 70 amp opto receiver with HK 5 amp UBEC because this same thing happened once before at about 75 feet in the air and then it "reconnected" and I pulled it out. I had a generic futaba receiver at the time so I put an original Futaba rx in to make sure that it wasn't the problem. I'm going with switched esc's now with at least 5 amps for my bigger foamies.

I just got a new Gray RC Lander and the build is in progress. I got it with electric retracts already built in, flaps already built in, and navigation and afterburner lights built in. It also has air handling mod build in to deter zooming up on landings.

Buddy (thanks Mike!) gave me his E-flite F-86 that was in great shape to make room in his hangar. I will put E-flite Delta-V fan and motor in it. Great...another project.

The Futaba 7C 2.4ghz radio is working out well. The Futaba 7 channel rx in the F-86 is working flawlessly and I'm getting used to the flap knob for varying degrees of flap instead of switch.

I'm also using two FrSky FASST rx's (7 Channel versions) (Futaba knock-offs) in P-51 and A-10 and this weekend was maiden for both of them and they flew perfectly. I had two of them shipped to my house for the cost of HALF of a Futaba brand rx! I hope they keep working well. If so, my fleet will be Futaba soon, except for Bind-N-Fly stuff from Spektrum (mostly for kids).

Skipped May update...too much going on. So here is the latest...

I have switched my electronic allegiance to Futaba from Spektrum. I lost the P-38 due to an electronic glitch on the maiden flight. That is one total loss and three other plane crashes in the last year due to unexplainable receiver failures. I now have a Futaba 2.4ghz 7C FASST system. I have ordered but not received 2 FASST compatible receivers made by FrSky to begin replacing in my fleet.

I put the original Futaba rx in my new Hobby King (Venom) F-86 70mm Sabre this month. My wife bought it for my birthday last month..woohoo! The maiden was a failure due to nose wheel hitting a patch of gravel and buckling and throwing a rock into the edf and shattering it. Ordered E-flite Delta V15 motor and edf and it rocks! Maiden with it was super and it's a great flying plane. See video below. It flies best with a Zippy 40C 4S-4000 lipo. It has electric retracts, speed brakes, flaps, and full house controls. The radio works great except the variable knob for flaps should be on the left side of the radio.

The FMS Blue Petie got new tail feathers this month and has maidened okay.

The FMS P-47 Jug is still one of my favorite planes to fly!

MaxJet F-117 Nighthawk lost steering servo and not sure how to get in to fix it...may become hand launcher!

P.S. Spektrum RX DSM-2 Brownout caused Crash and Burn and subsequent rebuild...see last three pics.

New addition to the Squadron...Thanks Terry!...Easy Tiger Models Saab J-35 Draken...3S-1300, 64mm EDF and it's a screamer! 20" wingspan and a more than 1 to 1 thrust ratio. I had to put aileron travel @ 60% and 60% aileron expo but after that it flew great without twitching (pilot problem not model problem).

It's a Swedish design and this model was for the 1000th anniversary of Austria.

Here are a few pics:...Continue Reading

The B-2 Stealth Bomber is still without electric retracts all wired up...think I'll just bungee launch it and see if it flies!

The Shark jet is flying great and now has 4S setup with HK Red Brick 50 opto ESC with HK 5 amp UBEC. The video below is with 3S setup and it ran fine with that but now it takes off in 10 feet vs. 35 feet. It has HobbyPartz 4800kv for 4S.

I have P-38 kit that is still in the box...lots of wiring to tackle.

FMS P-47 Tarheel Hal, FMS P-51 Blue Nose, Maxjet F-117a Nighthawk, Art-Tech Spitfire, Dynam A-10, FMS Flying Shark, and ParkZone T28 all still flying formation.

Blue Nose flies great...more shim, better take-offs. But, it falls off in loops something terrible. Elevator seems perfectly balanced...must be bending under load. Will try to put some strengthening tubes on control rods.

The Jaws Jet flies great but the motor burned out. It was the recommended motor/edf combo from HK for the Flying Shark but on the 4th flight the motor wires just melted. It came down fine though. About to put Exceed Optima 4800kv in it.

Here are some pics of P-47 from Club Photographer:

P-51 Blue Nose flew great EXCEPT that it has a terrible left kick on takeoff the likes of which I have never experienced. I pulled off prop/spinner/backplate and put a shim between firewall and motor mount and it was better but still too much left kick. Will have to put in double what I already put in to make a difference I think. But it flies like a champ in the air and on landing.

B-2 tried to maiden again and the nose wheel kept folding under as soon as I would move about 5 feet. Arrrrrrgh!

F-18C remaidened and crashed for the third and last time. Something wrong with electronics somewhere! Flew great for a couple of passes and then spiraled to 5 feet and caught it and flew it upside down for about 10 feet and then it crashed to ground...Good Riddance to bad electronics.

B-2 maidened and wouldn't take off due to too much weight to balance it. It tore off landing gear doors and one main landing gear came off but easy fix. Will try again.

FMS P-51 Blue Nose (given by Olflyer...thanks man!) was fixed and all control surfaces cut off and hinged with HK black hinges. Ready to maiden.

Yet to start on the Jaws Jet.

FMS Flying Shark kit from HobbyKing. It's a 64mm edf with 3 channels: ailerons, elevator, and throttle. No rudder or steerable tail wheel. Should make for interesting takeoffs!

I have a Hobby Lobby 4300kv motor from a dearly departed F9F Panther that will power this flying fish. I will also put a 40 amp ESC with a 3amp switched BEC. A 3S-2200 30C battery should be a perfect fit.

Jaws Jet should be a hit at the local Fun Fly.

I got my Spektrum DX6i back from Horizon with new antenna replaced. I've been flying about 3 weeks with it and no problems at all with any of my planes. I've flown 5 different planes with 5 different receivers with no problem whatsoever.

My P-47 Tarheel Hal has been epoxied and microballooned back together and flies great. I have the flaps dialed in at about 25% and it floats in nicely on landings and is helpful to reduce takeoff torque too.

The T-28D is put back together and flying great with one exception. The motor is "slipping" occasionally when I go from idle to full throttle every once in awhile. Otherwise it is doing all of the aerobatics that I can make it do. It looks a little worse for wear but is flying fine. We have been doing squadron flying with two other flyers with T-28's ... what a hoot!

The F-117a and the A-10 are doing great. Both have nagging nose wheel bends but that is the nature of those small wire nose wheels.

Just ordered Flying Shark from HK for our club's fun fly coming up in October. Can't wait to fly that EDF plane around for the kids. (OK me too!)

B-2 from LX is still maidenless. The gear is just a bear of a problem. Servoless retracts are now installed but need another strut. The Windrider gear are just too big for the small bay and no way to enlarge it much.

More later...

Had a bad rash of luck in July. Crashed three planes in two weeks. The FMS P-51 Mustang nosed and and cracked to pieces. Was on a "go around" after aborted landing about 20 feet off the ground and when turning gentle left, it suddenly spun right and nosed into the ground. Still have no reason for it. The rudder was torn loose on crash??? The plane was not recoverable.

The same day...I flew my P-47 using flaps (new thing for me) and it was in almost identical position as P-51 and crashed EXACTLY the same way. It might have been too slow on the go around and just lost airspeed but there has been rumors of a microwave problem at JSC that interferes with 2.4ghz equipment??? The Jug had a badly cracked fuselage on top and bottom, crooked prop adapter, broken firewall and a little rash on the wing. As of 8/4/11, all is fixed and ready for remaiden.

The next week my T-28 crashed while doing inverted maneuver and the problem ended up being an bad aileron servo. Fuse was cracked, nose wheel torn off, and cracked wing on left side bottom. Remaidened 7/30/11 and it flew well but motor is not quite what it used to be but it was serviceable.

Replaced P-51 with new Banana Hobby Starmax F-18, version 2, with 70 mm EDF and is 4 channel with working rudders. Replaced stock UBEC with Hobby King 5 amp UBEC since so much trouble with stock one. Ready to maiden this weekend.
