Well i HOPE they're not going out of business.
Maybe they can do some restructuring (sp) so it wont happen if that is the case.

As for engines- A good 21 will go just as well or better than an average 28 engine....I think...lol

You will get a better run time out of a 21

If your racing see what size engine most of the guys down @ the track are using

If your just bashing- buy a 28 engine and GO NUTS or buy an OS 30, do a little mod on it and it will decimate all.....lol

My mate bought a second hand OS 30, did a small mod on it and nothing could touch it. on the other hand he only got about 5 min run time but it was an awesome 5 minutes.[X(]
