May as well post my Jammin X2 CRT Conversion.
 

Alright, I've been doing a lot of research and was close to buying a Caster Racing R8T for $300 plus shipping. But then I found a Jammin X2 Pro roller for $160. The seller was a sponsored driver and he said the truck has some upgrades as well.

For electronics, I have a HPI badged Monster Mamba and a HPI 2650KV Motor. I know the motor won't work so I'm in the process of selling/trading it for a 2200KV or lower motor. (PM if you're interested)

I will get the RCM motor mount set, but I will need to figure out a battery holder.

Also, I plan on running 4S because I have a lot of Turnigy 2S Hardcase packs. Due to this, I'm thinking a 2200kv motor is my best bet. What pinion would you suggest I run?

Well if you have any info on any of these questions, let me know. Here are pictures the seller posted up.

nice truggy looks like it's pretty well set up

very clean truggy. Plug you spur/pinion into the speed calc to determine what you might do....

just do a search

14t should be perfect..

Use one of Mike's battery boxes...he makes them for many different vehicles, has a universal one, or he will build you a custom one to whatever specs you need.

I m using jammin conversion kit but rcm motor mount. Very neat n cheaper

What do you mean? Beyond the rcm motor mount, all that is needed is a battery box right?

yes & the rx box. Jammin one is very neat.

here u go

I've yet to find a place that sells that kit online and ships to the US.

If u want I can check with my jammin distributor how much to ship to us.

Btw there's jammin distributor in US right?

Should be. I thought Jammin was the same as Ofna?

Ofna is a distributor for Jammin, and they share some *things*...

Got the conversion done. I'm running the 2200KV motor with a 14t pinion. Top speed is just under 36mph running two 5200mah 2s hardcase packs in series. Tires are Proline Calibers.

That top speed seem right?

Update. Retested top speed with a freshly charged set of packs, high 39.7mph. Went down to 38.3mph after about 5 mins of running.

Nice but I think u need to put sponge at the Lipo as there's gap. The motor wire is too short too. When the car flex most likely it will disconnect.
