Hi Edward
I'll race Mugen cup (I use MTX3) on this Sunday, since their body rule is open, I'll run VDS, no longer try VDS on 1/10 touring for two years, what size of heat sink, bigger or standard may I use and what # of glow plug? Please suggestion, my crankcase was MAX with BRB, 0.5 shim, forecast racing day the temperature will be around 25C ~ 27C. Thanks!
William

PS. last racing Kyosho Cup I use V1RRR with M6 body & big heat sink #7 tf plug, 30% fuel, the engine after final temp. around 100C, environment temp. 25C.
