If you can wait until this evening, I'll calc the CG for you.

well checked against the first one you did for me for the 480 size and it matches the micro to a T :)

there is a difference between the location of the wing CG given by Compufoil and where you say of .2 inches

see attached pic

ahh but if i remeber correctly the wings were not exactly like scale. they were close but the wing cutter changed them some :(

Thanks,
Bradley

You can always balance at the forward position, then move the CG back as warranted.

Can I take this to mean that I don't need to calc the CG for you?

Happy landings!

yea I believe that it will be OK...
I overlayed the pic to the cg that you gave for the 480. wing is just slightly different
on the leading edge by about 1/4" so....

It is a Prototype I caint expect everything to go right on the first attempt right?

:) :)

I know your prob too busy to mess with any more post, but in case your still are, did you ever do a thrust run? just wondering how the ducting worked out. also what did the AUW come in at? Good luck with the maiden.

I give up for tonight.... :(

22 oz with 300+ watts.

S***ty thrust :(
