Who makes HPI's 21BB's?

[Renegade88]

I compared the HPI to a OFNA force 21 and it looks pretty much the same with the same hp and rpm range!
HPI claim the 21bb is 2.3 hp and revs to 30000rpm anyone?

Most RC engines look the same as the next RC engine. Generally once you remove company logos off the engine and but the blocks side by side they are virtually identical. To the best of my knowledge HPI makes their engine.

Actually, the newer HPI engines are Novarossi made. I can't speak specifically to the NitroStar 21BB, as I cannot find any more information on it. If you want, you can contact HPI and ask them directly. Go to www.hpiracing.com and look for a support link.
