This is a Great Planes Cap 232.
When we got it, it had a Super Tiger .60 on it. After fussing with that for about a month we decided to get a satio .91 4-stroke. With this bad boy it will pull it with unlimited vertical power. Right now we have a 14x7 prop on the engine. We also found 10% fuel will not do it. We needed YS 20-20.
Once you hit the gas it jumps right up!
It also lands very nice too.
