GENUINE HPI ROTO START 2 (2nd generation)
These genuine HPI are significantly higher quality than all the copies available
Ditch those pesky pullstarts
These work by fitting the back plate to the engine where the pull start goes
Then to start the engine you use the handheld starter with the shaft to turn the engine over
These are a much better way of starting nitro engines
fits backplates with 27mm center to center across the bottom two holes
All tested working
