Hi Everbody,

Been building this Jet too, any conclusions on cg?

Placed mine out 370mm from trailing edge Of wing flap.

Is this correct? Or will it crash and burn?

Any help would be highly appriciated!

not that I know anything about it.. but that should be really nose heavy.
usually
more likely closer to 27cm
that's by experience only.

He guys,

Glad I asked the question, but those answers vary allot!

So we are talking the distance from the flap tip towards the front of the jet:

CG's that I have seen so far:

1. 360-370 mm, this info came from a french forum.

2. 270mm (pavcon)

3. 330 - 340 mm (splitpilot)

Who has got the flight experience?

Thanks!

and that 115 mm was from the wing break across the leading edge right?


Thanks!
