Just bought a WM T-34 Mentor and would like to know which engine is best for it. I am already flying an Avistar with a ST .45 and would like to try something different but still on the budget side.

After this plane I am sure I will want to go with a warbird .60 size, so maybe I need to consider also that when selecting engine for the T-34. What do you guys think?[8D]

TT .46 Pro, great engine.

I don't see the connection with the 60 warbird. In any case, WM planes fly best at spec and the T-34 is no different. I have several planes from WM and each time I have been a little too aggressive with the power! However, after flying so long, I think the right engine with the right airframe is still the sweetest combination.

If you really want to reuse the engine with a warbird (probably not 60 size, though) you should get a 4-stroke. Something like a a magnum/asp 61 is just right. I have one on a scale cessna and it's a beauty with a wonderful sound. It won't go vertical by any means (8lb plane) but it is great for a budget, sweet sounding plane. If you have a little more budget, you can go for the Y.S. FZ63, a Saito 76 is sweet or something like an O.S. ultimate 70. Of course all these will mean that you will have to get a 40-46 size warbird instead.

If you oversize the engine, you can expect that it won't fly well as a second plane. If you're going from an avistar, stay within the range.

I forgot the obvious choice. Just strip your avistar for now, fly the WM until you're comfortable with it. Then when you think you can move up to a warbird, stick a 4-stroke TT 90 or Magnum/ASP 90 on the T-34, balance it and fly it. You will get a feel for what the Warbird's wing loading is like. Personally, I think this is the best choice. Of course, if you don't like the TT or Mag/ASP, you can always go to an O.S., Y.S. or Saito 100.

The WM T-34 will fly sweet on any .45 or .46 2-stroker. I know you wanted to stay on a budget, but check the prices on a Saito .56 or .72 on this board and get one at a good price if you plan on using it on a later ship. After a mess of WM T-34s at our club (two mine, one my son's, one my grandson's, etc.) the .46 2-stroke and .56 4-strokers seem like the best choices on that ship. It's a very aerobatic yet easy to land plane that will make you feel better than you are

This plane is being used a lot for racing. The required engine is an OS 46 FX.
That's what I got to put in mine.
Hope to get it done this Summer during the building season.

As these inexpensive and agile aircraft are being used extensively for pylon racing, the required engine is the O.S. 46 FX.
A new O.S. motor, the .46 AX has just been introduced to replace the FX. The old .46 has been discontinued and is hard to find. The new AX is very powerful and lends itself perfectly to the WM T-34. And at around a hundred bucks it doesn't hurt the wallet to much!
