Correct me if i'm wrong, but I suspect you were using a normal thread cutting tap. Thread forming taps don't remove any plastic (or metal!) and lead to much deeper thread depths. The Tamiya tap is about $10, and others can be found on the market. The Tamiya one doesn't have a lubrication groove... so there's that.

Using a thread forming tap leads to much stronger threads than thread cutting, and I've not wanted a power screwdriver to install any screws on cars that I've used a thread forming tap on.

Axon, Panaracer, Leespeed .... basically anything. The spur is held in place with screws so spur gear thickness around the pulley area isn't a problem.

Pretty much any spur with the 3 hole pattern. Which is most, since most modern cars rely on that.

Would a 63 Spur fit or you think that would be too small?!

Are you planning on running a 1:1 gear ratio? You would need a pretty big pinion to run that spur or the motor won't move back enough

Planning to run 21.5 with an r1 v16 and i need a spur to get ratios around 3.50
Also is this chassis compatible with XQ1 parts like roll bars and drive shafts?

I saw a normal XQ1 destroy Xray t4's and current model yokomos very interested to give the cheaper variant chassis a go and upgrade it if i like it.

You probably want something around 68-70T for 48P

I runa 63T or 64T spur with 33T - 37T pinion in my TA07 in 21.5T blinky so you're on the money with your range. I'm looking at this chassis to replace the TA07 for indoors, I love Tamiya but the upgrades will cost too much to make it competitive

You'll be extremely happy with the car! I just put this car on the track this weekend running 13.5T blinky and added ARBs from an old BD7 (1.2mm front and rear) with the car completely stock/kit otherwise (springs, shock oil, diff oil) and it was a gem to drive. Will try tweak the springs next week but it was a delight to drive and was game straight away!
