Chassis's running. Don't have the Piranha 25K ball bearing spec motor for the Winter Nationals Holeshot proxy so for testing sake, installed a motor of unknown origin but of high rpm with a 8t pinion and 28t crown.
BRM crown gear's boss was too long so had to steal a Plafit/Sigma one off my McLaren Elva build to fit the JK F1 motor pod. Not a lot of sources of these gears for 3mm axles.
Runs smooth with no hop but I need more acceleration from a 30t or larger crown.
Trimmed the kit's interior/chassis and after some severe cutting and grinding this'll fit.
Body mounting posts are set so the fit is tight but worth the modeling detail to me.
Will finish off with paint detail on the interior/motor and body.
