what pinion you running? should be on a 12 depending on track. the mongooses are a bit hit and miss, the motor is fine but a lot of people run other speedos

Hi Paul

What keeps blowing up?.....if it's the speedo there have been a few novak mongoose esc that I have seen blow up....I run a shark and most of us now use the Tekin RS speedo's .....these small 1/18th scale buggies seem to be working on the limit and I don't think the mongoose can cope with the heat.

May be worth investing in a Tekin.

the tekin is very pricey though. i run a bog standard nosram matrix without fan. fits fine on the top deck and copes easy with the 10.5

thanks for the help its a 12 tooth pinion i work at tayracers model shop so can send stuff back very easily. they even have a square cut in the shell for fan they werent too bad when my workmates owned the cars as they raced them in a barn in wintertime series at csor. i usually boot them up and down carparks and they seem to blow up miby i should just use them on the track for 5 mins at a time and not till the lipo cutoff comes on

yeah, if you are bashing the cars for 15 mins (a 1600 lipo can easily last this under race conditions!) then they will probably get a bit hot and strained. shorter burstws with cool down will help. Or a more reliable ESC
