Building a GPs Cap 232 and I was woundering which engine to use,The 90 4c or the 46 BB engine..Would u use the 2stroke or the 4 stoke on this plane??I would really love hearng from u guys and tell me why U choose the one u did and what is ur thoughts??
Thank u

go with the four stroke, I have a .70 in mine and it is way overpowered, I had to add a little nose weight with the .70, a .91 FS might balance it out, I used the servo in the rear of the fuse for the rudder, if you put the servo up front and go with a pull-pull setup you can probably use the .70 without adding nose weight. My Cap out climbs another guys .40 Extra that has a .91 in it. I'm running a JZ 14-5, it gives me 11 lbs of thrust and lots of braking. This is one of the best planes I have flown, just wish it was bigger.

Thank u for ur input,,I had seen a friend use a 91OS 4c and it done great but I thought I had the 46 SF so that when it time to see who else might have or is doing with one..
Thank u again and hope I get more replys!

I agree about the four stroke, but be careful about over powering this plane. Though it uses the same airfoil as the 40 sized (???) GP Extra 300, it builds up a LOT lighter. As such, you really don't have to overpower it. In fact, that is one reason I suggest to people that they look at the four strokes on this plane. By using the larger diameter and lower pitch props, you can get thrust for quick acceleration and also drag for downlines, without building up excessive speed.

Just so you know, I first powered my GP CAP 232 with a YS .53 four stroke. Some of the guys at the field thought it had a .91 four stroke the way it flew. However, it didn't quite have unlimited vertical in the summer heat, so I have since dropped a YS .63 into it. I suggest to most people that either the YS .63, the O.S. .70, or the Saito .72 would be about perfect in this plane. Though I know others have used .91 sized four strokes, to me it is just extra weight.

Mine is pretty much stock, though I did fiberglass the wing ceneter section, add dual aileron servos in the wings, and also added hardwood wing hold down blocks under the stock lite ply ones. It is currently my favorite plane to fly, hands down....

Thank u for ur thoughts,,I would agree on the YS63 to be the best engine for this one..Some of the 91s are really lighter in weight then the smaller 4stroks!!I would like a Saito65 on this one but I just have this 91mag or a older Enya 80 but it wieghts more.One thing is u dont have to try and run this plane at full speed,,Iam not a speed freak!!
Sure liked the Job u done on urs to..I will post a picture when done..
