ACEGLH
so i have a new glh kit.I had one back in the day.about 1991 with a teedee .09 it was quick.but im thinking about a os cv 15.il beef up the fire wall.its too bad that jett does not make a .09.it may fly like a brick but all speed planes do.am i way off tryin a 15?or should use a .049?with the right engine i think this airframe could hit 160.what do you think?

RE: ACEGLH
The most powerful .049-.061 engines can only make a stock GLH do around 90-100 mph. The wing is too thick, and the plane is generally too big and heavy. The fuselage is about twice as big around as it needs to be to conceal a .09 and all the rest of the gear in back. As it sits, this plane probably hits the wall at 120-130 mph with a OS.15.....
Maybe one of those Rossi .15s is capable of 160 in the right plane, but the CVA would need some work I think.

RE: ACEGLH
are you sure it will hit the wall at 120?to me it seems like a scaled down q-500with a swept wing.you know what your prob. right .but 120 with that little snot.will feel like 170

RE: ACEGLH
The hottest prop I've tried for the CVA is the APC 6.5x5. It's good for over 130 mph on a sleek enough plane. The CVA isn't timed like a Nova Rossi so it's going to be more limited. Last summer mine hiy 133 on a little delta which meant the rpm had to be 28,000 to do that. I think those NovaRossis are good for more like 37,000 but the prop would have to be smaller than the 6.5x5...I assume. So maybe with experimenting, the CVA is capable of more with a smaller prop...this would save having to buy a NR for hundreds of dollars for the extra mph.
This sounds like a great project, give it a try. I just happen to have a slightly slimmed down GLH [or 2] for 1/2A racing and have given the idea of implanting a CVA some thought, too. [8D]
IIRC, our rules called out for a 1 inch thick airfoil but they allowed immediate tapering from the high point instead of the rulebook wing that has to maintain that thickness out to mid span.

RE: ACEGLH
I have a CV .15 on the way, or so I think it is because it is packaged with a DF unit. Look forward to messing with it. Ever spun a 7-3 on one CP? Wondering about the gonzo aerobatic possibilities on something small.
