Actually, the person who started this thread did, in fact, own the ST-3000 and currently has a Moki 180 on the same plane. Though my vote is still not verified, I'm expecting considerably more from the Moki than I got from the ST-3000.

My experience with the ST-3000 is somewhat limited. I purchased an old (new-in-box) ST-3000 and broke it in using Wild Cat 15% for 48ozs. I then cut the Wild Cat with straight methonal and ran another 16ozs on the bench. My first and only flight was another 16oz of Wild Cat/Methonal mix. The engine ran great, good idle and excellent transition. I was impressed.

The problem was it ran out of fuel, my mistake, and I ended up deadsticking the 1/4-scale Hanger 9 Cap into a tree. Rather than repair I traded both airplane and engine.

Engine performance with a Zinger 18x8 was good but on that airplane not awe inspiring. She took off 1/2-throttle with no difficulty and could easily do basic aerobatics. It did not, however, have enough to hover that 15lb airplane.

My expectations for the Moki is much more. Initially I'm going to run with a Zinger Pro 18x10 and eventually move up to a 20x6-10 if it makes sense to do so.

Regardless of what everyone is saying here, you are correct. We really don't know until we done a torgue test on the engine using the same prop. Someone also said that to be fair we should use the same fuel. I don't subscribe to that. The big Super Tigers excell with very little oil, the Moki needs a much higher oil content.
