Best Engine for RV-4 Great Planes
It is very scale-like and quiet. With a 2-stroker I'm sure it would be more aerobatic, but I love the way it flys - very SOLID and smooth-like.
At full throttle, it can get up and go at a respectable speed....but I'm sure a .40 sized Stik would pass it in the homestrech!

Best Engine for RV-4 Great Planes
I would put an OS 70 surpass II on it. I was going to build this airplane and have the afformentioned engine. I decided on the Great planes ultimate instead. If you want the scale sound throw an exhaust diverter on the muffler, or go with the pitts muffler set up. The 70 will give you plenty of power, and will also give you a nice scale sound. Thats my 2 cents

I'm flying mine with a Magnum .46 XL 2 stroke, with pitts muffler. It's great.

RE: Best Engine for RV-4 Great Planes
HI! I have a plane similar than your rv4 (Super Sporster) size 40 and I have a 70 surpass in mine this (IMO)
is a great combo w unlimited vertical , nice put put put sound, the 52 4 strokes is a little weak for this plane
but if you want to fly it scale its a good choice.............

Saito 82 is much strong than 70 surpass but he dont need more power IMO, the little OS 70 Surpass can easily give to him unlimited vertical with a 5 lbs plane
