Composite Roo CG
#1
Thread Starter

I'm triple checking CG before tomorrows maiden flight....and having been burned by mis-printed CG info on other planes....
:
The manual calls for the CG to be 100mm/4 inches in front of the spar.
Anyone have bad experiences there? (Though it does seem "tail-tipsy" while empty there.....
Thanks!

100mm in front of the tube (not Centre line) is a good starting point.
The gear is positioned to give the best take-off rotation ( a problem with the old Roo )
With fuel and the canopy on it will be fine.
Keep the up in after take-off untill the speed builds as the high turbine makes it want to tuck until some speed is reached at high power settings.
