Wow, just read the whole thread today. Didn't get much done at work, oops!
Love your Wraith! I just got one last week but can't play till xmas. It's 75% for me, 25% my ~3yo son.
As such, I was planning on putting a 55t motor in. You say it's too slow and you need wheelspeed, but on the flipside, when I let Finn play with it inside to start with, I don't want him destroying the joint like he does with the current 'toy' rc cars.
I am also new to crawling and havent had an RC car at all for years, so I don't mind it being annoyingly slow to start with and then speeding it up later as the boy gets the hang of it. I will still have the stock motor if I need it faster.
I was also toying with changing the spur & pinion to reduce the gearing to the same effect.
With my use-case in mind, do you think the 55t would be OK? I can always put the 20t back if I can't bear it. I was also planning on some cheap NiMh to start with but this thread has got me pondering just getting a 2S for longer life...
Man, I also now want to put all these siny Vanquish parts on it! Boy am I going to be in trouble, it was hard enough justifying $300 for the RTR kit, now I have to justify shiny titanium and aluminium, eek! *restrains*
And again, thanks in advance Josh, for providing all this testing, advice and info to the community!

Tom actually a 55t may be a really good choice for you (more so your son). I would suggest taking the nut off the slipper setup and putting some loctite on it. Then you can leave it on a more loose setting and it won't come off (prone to happen unless you have it very tight). This will really save parts if your son puts it in a bind and puts the hammer down! :ror:
I would suggest 2s lipo for sure. You can get some great run times, sure to keep your son entertained for long enough for you to still have some run time too. I would go for something in the 5000 mah range. I run a 5250 in mine (3s) and when we have get togethers I run the same pack for several hours (although we aren't driving non-stop).
Good luck man, have fun!
