8ight-T Spur and Pinion Help

[Overkill]

Hey guys, I am slowing doing up a 8ight-T when the parts arrive from overseas and I have a couple of questions. After reading the Zippy thread I thought I better get some opinions on this Losi setup I am starting.

#1 When I use the speed calculator I am getting a speed of 52MPH using the supplied 45t spur and 15t pinion (Losi Conversion) running 5s and the 2200kv CC-Neu (I punch in the 1515/1y). Have I input the right figures if I use Front/Rear Diff ration of 4.3, the Trans of 1, spur 45, pinion 15, 18.5 volts, 2200kv for motor and input tires of LPR Bowties 5.6???? If I have, I think the Losi kit is set for their 1700kv motor because that comes in at 40MPH using the given formula.

#2 If I have inputted the correct data and I am looking at those sort of speeds with the Losi Conversion, for those that have this setup especially with the CC MMM Combo, what sort of temps are you experiencing with all individual parts, ie: motor, ESC, Lipos? Is it advisable to maybe gear down and try and find a plastic spur that will fit, maybe something in the lines of 48T or 49T? Try a 13T pinion or there abouts?

To be fair, the more info I can get with places to purchase from regarding spurs and pinions that may fit, the better for me. It can take me two weeks for something to arrive and I would rather do an order for more parts than needed and have heaps of spares so I can test different combinations all in one day, not one day every two weeks

#3 Who loves their Losi 8ight Brushless I DO

I know there is three questions, but the third one is the one I wanted really answered Thanks in advance.
