I have my ESC (Moxie 80A professional series) in the under wing compartment and it operates without any issues. I also made a small intake duct:

I have my VidTx out on the Wings and the "Mic" is in the
VidTx itself.... what are you guys using to cover up that built in Mic?

The Wind Noise is crazy loud....

Can I use HotGlue or Some sort of Silicon..... anyone have any ideas for me?

I can't use foam on the VidTx itself because it will melt it

Thank You

p.s. VidTx is from HobbyWireless

The white wire is the audio lead. Cutting it will halt the audio to a lawmate xmitter. I use a EZOsd and the right audio out is attached to the white wire not to the board but to the xmitter on the backside for tracking and telemetry.
The packet audio telemetry is nearly 100%.
I have a small 12 volt fan that is mounted near the xmitter. If it lands somewhere remote I want to assure the vid Tx stays cool.


Take care

If you're worried about the VTx melting foam, I certainly wouldn't use hot glue! It would just melt that too!

Well, apparently I just jinxed myself:






Was out flying this evening and while making a full throttle pass, the ESC shutoff and the plane nose dived. The weird part is, the throttle cut out and then a split second later it dove straight down as if the elevator was full stick forward. It's weird because I have a 5A UBEC powering the servos and receiver.. so the ESC cutting out shouldn't effect the servos?

oh well, the damage wasn't too bad. Should be able to repair it.

That sounds more like a radio going into failsafe with the elevator not set correctly dont you think ?

+1 ^^

Probably because of the close proximity of your 80 amp esc to the receiver antenna.

ESC's make lots of switching noise.

Sorry to see your plane smashed....

This is how I fixed mine after the first one failed in teh compartment....

Shave off small bit of foam under teh motor to create a flate, cyano'd the surface, then velcro'd theESC on and to be sure use a cable tie.
The only thing I wish I had done was to fit a small tube for the tie to go through so it doesn't pull on teh foam. I'll probably retrofit that.

But we don't think the problem was heat related the RX more than likely went into fail safe.

This is what i'm going to build.

Hi. I'm planning on building a Skywalker and thought i would share what i have found to be a good setup for this FPV plane. I've choosen this parts based on what i've read here and advice from friends flying this FPV plane today. Since i can't buy it all together i have to buy over a few months. I have a quadcopter today which is going to fly as a FPV quad when the parts needed for it arrives. This month i plan to buy the following:

April:
BEV-KX181H-PAL Camera 82
BEV 1.3G 800mW 74,99
BEV-2.8mm board lens 9,99
CE OSD V1.3(Newest) 92,99
BEV-GF protect kit 21,99
Total $281,96

May:
Fatshark RCV922 BASE Edition $275

June:
BEV-FY-20A II Flight Stabilization System
Skywalker 168cm EPO airplane Version II
80A brushless ESC Turnigy Plush(I have this already)
HXT900 9g / 1.6kg / .12sec Micro Servo
TR 35-36A 1450kv Brushless Outrunner (Eq:2814)
Turnigy nano-tech 5000mah 4S 25~50C Lipo Pack x2
Turnigy nano-tech 1600mah 2S 25~50C Lipo Pack x1
Chainlink (433MHz for video)
Total $541,77

Total $1348,73 with the Ardupilot Mega($250)

Im not shure what kind of controller i want for this project, but i need advice on IkarusOSD($130) vs Ardupilot Mega($250) and maybe others.

My Tx is a DX7. I'm planning on buying a Turnigy 9x.

That's a lot of stuff.

How about this:

1) Buy the plane, motor, ESC, servos and battery. Then go fly it.
2) Add a VTx and camera. Then go fly it.
3) Add an OSD. Then go fly it.
4) Add autopilot, stabilization and various must-have doo-dads late this summer.

It'll still take months to accumulate the gear, but it'll make a whole lot more sense once it's finally all in the air.

Now, if you'll excuse me, I'm going to go run a marathon. Training? Bah! How hard can it be?

I bought the DOSD a couple weeks ago and realized I shouldn't install it for at least a few more weeks until I'm certain everything else is in order! You can buy all that now, but you'll probably end up not using it immediately (and you probably shouldn't). Wouldn't want to lose all that cash just because you rushed things.
