Brushless Losi LST2

[Robl45]

have asked questions over at LSTForums and it was suggested I may get some better answers here.

Looking to make my LST2 brushless for relatively cheap money. Just going to be bashing around my house.

I will probably go with turnigy 100amp esc and FD motor mount. RC monster pinion adapter. As for motor, will most likely go with one of the FEIGAO XL motors.

I am planning at this point to use 6S to alleviate high amp draw. my main concerns are how will the truck perform when jumping and climbing up steps and such with the heavy 6s packs? Initially I will probably use 6s 4900mah flightpower packs because I have them for my trex 600 heli that I don't really have time to fly.

So assuming the 6s will not be a problem for climbing steps and jumping, which XL motor would I use? I have heard that 10XL should be good, but with the stock gearing on this truck, is that the best bet or should I maybe go 11XL?
