ok, the aluminium rods are slightly too big to fit through the hole in the gearbox mount, but its only 0.2mm bigger. i can buy a 4.2mm drill bit so i guess enlarging the hole by 0.2mm is not going to be a major issue?

Don't think that would be a problem in itself...
Not sure you could find such a small drill that's long enough though. :unsure:
Sanding it to a slightly larger diameter might also work.
The difference doesn't seem to be much.

ive tried a 4mm drill bit through the hole and it is just long enough to go right through. i may try putting the rod in a drill and spinning it up and running some emery cloth round it. cant be hard to lose 0.2mm off it. its worth a try

Good plan. Definitely worth a go.
I was just thinking that it would probably work after I had a look at half a gearbox. :whistle:
They were bigger in my recollection... :lol:

SUCCESS. 5 minutes in a drill with some 320 wet and dry and it fits perfect :woohoo:

...
3. there is a resistor on both connectors where the wires solder onto, one has snapped off.do i need it and if so what size resistor do i need to get
...


Has it got a number on it? ... TBH I'd expect it to be "472", which means it's a 0.0047uf / 4.7nf capacitor ... try this:

is there a certain way to set up the tamiya ESC or is it the same as other makes?
turn on the TX, then the RX, then wack it up to full throttle and its ready to run?
i notice there is a reset button on it :huh:
