Mod motors are heavy!
I run in good 'ol povvo 540pro, with a 32g servo, a vfs1 speedy ans a futaba 3pk receiver. I also don't run a heatsink, and all the wiring in no longer than it needs to be (including trimmed servo leads). When I bought the car off a mate it had all the good stuff: lightweight everything, aluminium and titanium fasteners everywhere etc etc.
I didn't know it was underweight until I got pinged by a scrutineer at an event.
So there you go, I'd love to say I did well to get the weight down, but I didn't. Unlike my off roaders, I just drive the MSX once a week, and don't think too much about it in between times. I do know that a stock or a mod motor weigh significantly more than the Johnson, though.
