I've done a search to prevent spamming the board, and I've found LOTSof good info on this kit. One guy stands out, he did retracts, working canopy etc...but it was electric.

I'd like to build this model with either a 4 stroke or a gasoline engine. Which between the two are better, and which sounds better? I'm new, although I've flown trainers in the past. They always came with whatever it needed, so I didn't have to figure all this out.

I want to run a 3 blade prop, so I'm sure that's gonna make a difference too. So here is what I'd like to know...

What engine (either nitro 4-stroke or gasoline) that will be compatibale with a 3 blade prop

Which 3 blade prop

Which remote glow starter, and where to mount it


Thanks for any answers,

G'day

I don't have direct experience of the P-40 but there are a number of similar planes at my club.

I had a look at some sites which sell this kit and they are saying a 140 four stroke. I don't know of any 140s but there are Saito and Laser 150s which both would power this sort of model well. The OS 200 would be another possibility though the ones at our club always seem to cause problems. I have both the Saito 150 and the Laser 150. The Saito is slightly more powerful but the Laser is easier to use. There is not much in it though. Both are excellent engines. And both sound great.

As for three bladed props, I would start with a two bladed prop (say 16 x 8) and then experiment from there. Usually if you go to three from two you drop an inch in diameter and add some pitch so possibly 15 x 10?

I had a similar sized CMPro Corsair but I gave up on it. It was just a pain to put together and did not meet the specs on the box. A lot of the hardware was junk too (wire that snapped when you tried to bend it, plastic bits that were not strong enough etc) so you might find you have to replace some or all of the hardware. Then again, things may have improved too.

Have fun and don't expect it to fly like a trainer. If you try to pull it into the air too quickly it may just tip stall and fall out of the sky. I had a P-40 that did that. You need to take off gradually and fairly flat to get airspeed before you rotate.

Thanks for the info Mike![8D]

I want to start this thing out with 3 blades, just so I'm used to it.  I've been away from RC planes for a while, so I plan on getting another trainer to mess with before I even attempt to fly it.

I was thinking the Saito 180 for an engine...is that too much for this plane, can you have an engine that is too powerful?  Or is it good to have power on tap.

Also, I'd like to know about retracts, which are the best for this kit?  I've read about Sierra and Robart, which is better? and pneumatic vs electric?

Sorry for so many questions, I just wanna do it right.

Thanks much!

If you go into the ARF section on the forum you may find a number of threads on this plane and see what others have done with it and see if there are any changes needed. An engine doesn't know if it's got a two or three bladed prop on it but Mike was correct, if you have found a two blade that will fly the plane the way you like then a three blade just goes down one size in length and up one in pitch to get close to the same flight effects. You need to test props to find the one you like best.

Thanks Gray Beard, but I've not flown it and won't for a while. So I'm not sure how it would fly with a two or three bladed prop...but Iwant to start out with a 3 bladed one. I found a LOT of the threads on this plane, but the big one with the most details was an electric build. I'm guessing I'd use a different prop for a gasser, but I could be wrong. I'm asking first, so I don't throw away my money.
