How can an RV-9 possibly cruise 50 mph faster than a 152 w/same engine
yet stall at the same speed and give up nothing in terms of stability, etc.? P.S. Zoom is a wiener. |

I wouldn't say a "complete genius" but damn near that... I built an RV-6 and was always amazed at how easily it handled. You didn't have to move the stick so much as merely put a little pressure in the direction you wanted to go. IMHO, the RV aircraft is as close as you can come to flying completely by feel and instinct. John Ammeter |

Low drag and airfoil...

Ok, I knew that much. :-) Actually, I meant to compliment Van because
it's obvious he really knows what he's doing and designs some wonderful aircraft, but looking at a 152 up close it's really not too difficult to imagine something going lots faster with the same engine. :-) Lots of bumps & draggy stuff all over those things.

If anybody cares to humor me any further-
One question I have on my mind now is why build a 7A over a 9A unless, possibly, you really have to have the aerobatic capability? Or really want more than 160hp? Cause at 160 the -9 just performs better. The 7 gets you a measly 2-3mph better cruise with a whopping 7-8mph increase in stall speed. And the -9 is a better XC platform as well, is it not? (I still have not gotten my demo ride.. didn't happen at AV this year as I got there too late. Almost got a ride in a -6A once but then the airport went IFR.) Yeah, I'm still in the 'dreaming' stage but I'll get there (building the thing, that is). At least I have the PPL almost out of the way- checkride scheduled for 1/22.

Unbolt engine from Cessna fuselage...." :-) :-) :-) |

Best example of same basic design that goes much faster on same engine is the GlasStar. It is very comparable in design and size to the 152 but has performance figures that are far better.
