I have the Nova head on my 25 and the performance enhancement was incredible. It runs around 30 degrees cooler so the engine has better performance all around. Highly recomend it.
That isn't a better price than just ordering it directly from their website. www.novarcproducts.com
they have some really nice stuff, I have the cooling head (for wasp .26) and clutch shoes
Thanks for all the help guys.. I ordered it direct from Nova RC parts and should get it in like 3-5 days and when i do i should be getting a video camera so i can make some vids of me going off my home made ramp
