Default Ofna Hyper 21 ~ 8 port.....opinions?

I'm just looking for a low budget 21 to learn how to drive a 1/8th MRX. I don't need fancy high end HP, in fact, my stock Associated .12 kept me out of trouble with my NTC3 until I could drive and move up to a Novarossi. I always finished and passed the hot motors that launched into the wall.

So what's your take on the Ofna Hyper 21 8 port motor - do they hold up @ 20% Nitro and do they tune well?

I have also done research on this engine...the general feelings I got from all the reviews and opinions on the engine is that it is a great buy for the money. (can get them between 80 and 130 on ebay new) The only thing that was put down about the engine is that many stated the carb wont hold a tune as well as some would like. The fix for that was by putting a O.S. carb on there, sorry I forget which one.

All in all, if you got the money and the ride to put it in GO FOR IT!

I have one cheap horsepower but you got to work with it!! Seal it up so you don't have air leaks and put the os carb on it.
