Has any one had a problem with the HPI Nitro G3.0 as I have done two engines they just seem to last 1 gallon before the top end of the conrod snaps and smaches the piston up, HPI are good at replacing them but I would prefer a more reliable engine and does it realy put out 2.2hp as they state.

I was thinking about geting the OS .18 CV-RX engine to replace it would there be much differance in power & reliabilaty.

Cheers
