Well...
It's all together now, has been for a while...
I ended up going with the Hobbypro conversion kit (before this decision gets slandered as supporting the clone slipperential, they own, or atleast partially own Jconcepts, Picco, and a few others, so I am sure others here have "supported" them also).
The conversion kit wasn't the greatest in quality (mainly just the motor mount) but for the price, it is certainly acceptable.
I also got the Hobbywing 150a XeRun, and the Leopard 4082 1600kv motor.
Both are going great, really happy with them both.
They truggy itself is going pretty good, as tough as a brick s*** house, handles good, even with bald tyres (got a set of crime fighters here and ordering a set of Nanda Split V's soon).
Got a $13 Power HD servo that has been doing a good job so far will be getting replaced with a Savox 1267 soon (I have a CC BEC also).
Going to need a full bearing kit put through it soon, a couple on their way out, getting a little sloppy and gritty.
Steering racks are a little worn also but still usable until I get some spares.
I have it geared 12/46 at the moment which is going pretty good but I will be bumping it up to 15 soon, see how it runs on that.
Temps have been really good, a decent thrashing sees the motor at no more than 50C (highest I have seen is 48C), ESC maybe just above ambient and the Lipo's about 20-26C.
I got an SJ Propo Absolute 1807 Dual 300W charger which has been running great (I originally got 2x HK Eco6 200w chargers but both ended up being duds), got it running on 2x 15v (running at 17v) 23A power supplies from Himodel, not bad for the $23 each I paid for.
I have the Turnigy 130A watt meter coming next week (hopefully), so I'll be able to see what it all draws and see how much power it really is making.
