RE: richmodels quickie 40
It's such an odd and un-conventional model that more than likely the post you found here on the RCU was the one that I started. Follow my suggestions on the CG, wheel alignment and control throws and you'll be ok.
I've flown mine about 10 times----and have yet to attempt an aerobatic manuever with it. Supposedly it will loop, but not sure about it completing an aileron roll.
