Engine recommendations please.

I am looking for a replacement engine for my GS Storm (.21 B01).
I would like to stay with the .21 size but would consider something smaller if the power was there, and want something easy to tune, something that will hold a good tune, and good customer support. Some of the guys at the track mentioned the OS RG as a great replacement. Let me know what you experts think. Thanks.

I'd say that for the price the OS RG would be a great engine. OS is known for quality, durability, and the ease of tuning. I have a .12 and .15 by OS and both are very forgiving and great running engines.
Another engine you may want to look at is an Ofna Hyper .21 4-port. This is a popular engine that runs very well, but I have had no experience with one yet. Id probaby stay away from the 8-port version because I've heard difficulties in break-in and tuning. It is a lot less forgiving than the OS.

i have the XTM 24.7 engine and it is a beast. it runs good, fast, and cool. the break in was really nice and easy too.
