Thats when I realised that the gear from HPI roto backplate fitted and has worked fine to date... I also use a cordless drill with low torque setting now..... if it is possible to find another of these engines when this one expires.... I will not hesitate to buy again.... even with the starting issues.....

I wish there was more availability here in New Zealand.... I wish I could sell and promote them here as R/C nitros are rare here in NZ... yet all that see mine really are interested...

GOOD WORK STS
