I have one of each. You can't go wrong with either choice. They both have thier good points and bad points.

If you are familiar with OS engines, then I would stick with the Hyper. Tuning is fairly easy.

If you know anything about YS engines, then definately go that route.

If you're new to nitro engines and don't have much experience with either, Then get one of each.:rolling
