I've got a friend with one of these who wants to build a stuntship for it. Anyone fly stunt with one of these? How'd it do?

I haven't flown one but a few years ago someone was flying one at a contest I went to and I was impressed with how it sounded and flew. Sort of have wanted one to mess with since. I have several of the regular K&B and Veco .61s. They are well built-just sort of heavy. I'd think they would perform along the lines of the Tigre .60 if you weren't concerned about the weight.

I have flown both in my Thai Angel. The Clarence Lee version and the Twister version, both from MECOA. The Twister engine, IMHO, had a little too much vibration for me. The Lee version is better in the area of vibration, but is extremely sensitive when it comes to venturi's and NVA's. I changed the OEM out to a ST NVA and Jim Lee Venturi. Both versions are not hurting for power. I also did away with the OEM muffler and went with a Randy Smith Muffler. Most of my engine runs have been consistent, but I have had symptoms of "surging." Over all both are well built engines and seem to be getting better the more they are run in.

Russ Gifford used to use K&B .61 engines and one of his last model I saw had the Twister version in it. Like Dave says, they sounded nice and seem to have plenty of power for the big models that Rus built. I have a Twister and several other K&B/Veco .61's to try in an appropriate airplane just to experience them.

I would bet that engine would benifit from a sealed front bearing.

Thanks all! But what is a "Twister" version? What version of K&B 61 (with the unique-looking gold head) do I have pictured in my original post? Are your comments referring to the engine I have pictured?
Would a Legacy be a good match for it?

Scott you are showing the Twister version with the smooth gold head.

Read any instructions or paperwork that came with the engine. The engine is called a Twister because you can rotate the head to alter the compression. There should be a special spanner wrench to fit those two holes in the top of the head. That's about all I remember about mine, and I have never run mine. I think the .60 sized Legacy would be an excellent choice for it. You might want to think about shortening the nose a tiny bit to allow for the engine weight.
