There are 3 Ofna/Force engines. The p4 would fit your application best probably. From what I hear it is for the beginner so it's easy to tune. It has 1.7 horsepower (pretty good) and 4 ports. i don't know about the Ofna Hyper engine that most MPs can be bought with but that's what I plan on getting.

Don't be intimidated by a .21 engine. Generally, I think they are easier to tune than the little guys. I'm not fimiliar with the Force .21p/s and couldn't find it on the OFNA website, but my buddy owns several OFNA engines. Do you know how it compares to the Hyper .21 Ofna sells with the MP kit? How much horse power? How many adjusting screws? My experience with Ofna engines is that for the $$$ they run pretty good and they aren't too difficult to tune.

I run the P4 in my T-Maxx. It has lots of power but the Hyper will have lots more. 1.7 HP versus 2.1 HP. One thing i would do though is turn my needles at least 6 turns out for break in. The instructions say 3 but this was way too lean. After i broke my engin in I am running around 3.5 to 4 turns out on high, just past flush on the low side. I have also heard that the Hypers are also this way. This is my first .21 but it is way easier than any .12 or.15 i have ever had
