and to be honest, like 80% of the time i run stock anyway (at the time i got steel ones, i ran mod)
so strength of the delrin ones compared to the stock isnt a problem (i found stock outdrives to be strong enough for 27t motors)
its just that its a right pain having your dogbones popout with the stock outdrives....just trying to find an alternative to the steel ones...that is much lighter (my tc4 weighs 1600 with the fan kit
and steel outdrives ) and dont let your dogbones popout during races.
i think im going to give the delrin ones a shot in the near future.
