Moki hands down. I don't think any of those will compare. Ok i dont have any experience on the big STs but I do on the Moki. great power and runs well on 0-5% nitro. run a 18x10 Wood prop for break in. make sure its rich. it will take around 3-4 gallons to break it in though. power will slowly increase on. Once broken in will last a very long time.
