If those servos you speak of are the HK 5320, they are in stock right now!

Too late, I counter sunk the brick into the tail section:

Looks like the best place to me!
You will be able to counterbalance this with battery and motor right?
I hope the wiring weight is small as you must go all the way to the front for the battery and motor.

You are going to need to remount the brick.

#1 it will be tragically tail heavy

#2 it's backwards and the AS3X won't work properly (even with the programming card)

Just now thought about it, but those are some massive control surfaces for a Mustang!

Me too

Battery and motor even it out nicely, with the KFm2 CG sits between 35 and 40% of the chord.... And when I get the ESC I'll have even more weight to move around to balance the CG

Wiring shouldnt be too much of an issue, once I have my ESC only 1 wire will need to go to the brick for the motor. The servos use 32awg wire which doesnt weigh much.

#1 - see above
#2 - crap I think you're right
Elevator- works properly
rudder - is backwards, reversing the channel doesnt help
Ailerons - havent tried, need to solder the connectors on

Thanks for catching that before I got too far in the build

EDIT: Double checked software, and there's a sensor output direction, so I CAN make it work where it is, phewfff

Hehe! Im definately not going for scale performance

With the software its a pitty you cant add your own sensitivity settings, theres only a handful of settings you can choose from, Im just going to have to go for 3D/aerobatic and hope for the best :

Put your wing on and balance before mounting everything. Looks like you will need a very heavy batt to balance. Hope im wrong.

Do you guys think this bricks made of lead?

Its only around 1g heavier than the ar6400's.

At the moment its kind of nose heavy I need the battery towards the rear center of the wing to even it out at 35-40% CG. Things will change once I have the linkages on, but not that much, even if it does I can put the battery under the nose in the worst case scenario

Besides with AS3X the CG doesnt need to be spot on.

With the gears facing rearward I still think your going to have major issues, sensor output direction or not. Your brick is doing the opposite it thinks it is.

Thanks for the warning, but I'll see how it goes. If I crash it or it doesn't work I'll make a new one, no biggie really, after all its just a piece of foam

Where it sits at the moment makes the most sense to me, the control linkages can be shorter and the servo wires dont need to be tangled around them. Plus the CG works where it is, and the red light on the RX is even facing the right way for navigation

I know I'm new the conversation but with the board facing this direction the control rods will have to drag over the servo gears causing the binding of the servo. I know because I ran into the the same problem when turning a guillows javelin rubberband plane into rc. I don't know if you have seen this issue causing a problem or your design allows for the clearance. Hope it helps and good luck on the build its looking good.

Thanks - I already have four on hand, and have ordered several 1.9g 5330s - also in white!

I'm sure you guys have seen them but I am pretty excited about this thing. Its a micro skykart that I did some re-enforcing on. I had a similar one a while back but the foam warped so bad from its own weight that I had to trash it. So I have taken some thin flat strips of cf and used foam tac to cement them into place.
