Can somebody with a scale or if they otherwise know the exact weight of a stock puch oem flywheel please either post it here or pm /email me. I will email that weight to Willi at hpi and encourage him to make a weight which when added to the hpi mini will yeild the exact weight. Yea the performance will suffer on some aspects especially off the line but then folks can dispense with it or use the 300 gm weight already available.
I have a stock hobbit flywheel and will do the same for that. I assume there isn't something unique to a e50 design vs other small two strokes that would
Make this premature bearing failure isolated to puch.
That will then only leave the actual curve issues of the hpi on the table.
