Speed update!
I just ran 7 passes by a 100ft section of road to calculate top speed and after eliminating the fastest and slowest time my top speed is........
44.2mph with a standard deviation of 1.7.

here are the detail
tires: worn out dirtpaws
gearing: 10t thunder tiger (e-raptor) pinion & 46t sur
motor: Novak HV4.5 w/ 5mm shaft
batteries:2x Maxamps 2s 10,000mAh lipo

In all I took about 10-15 runs, messed up the stopwatch on a few, forgot how to drive for a few ect. In the end, the motor was only slightly warm, the esc and batteries were room temp.
Sunday I am taking it to the track to find out how long it can last without thermaling (and to see how badly I drive)

what kinda runtime are you going for with 10,000mah lol

That is a cool buggy.

Be sure to update on how it goes at the track

Long enough!
Honestly, I have seen a few times at the track I race where they have made one class run their second 5 minute qualifier and then run a 20 minute main 5 minutes later.
I wanted to make sure that I could get 25 minutes of racing without being out of battery.
Hopefully, in an ideal world, I will find that these batteries do last way to long, and I can get a pair of decent 5000mah or 6000mah to save on weight, but since the cells were cheap, I figured I would go overboard first and then, if I can, go smaller, instead of going to small first and not being able to run.

Went to the track yesterday...
Not so successful.
I had a few motor mount screws come lose which allowed my spur gear to strip (plastic spur).
Fixed that and then cracked the ball cup on one of the front CVDs. I bought the CVDs off of ebay from China, so it is likely they were poor quality, I ordered a new set of fronts (stock kyosho this time).
assuming the parts get mailed today, I should get them be Wednesday, and I will take it out to the track Thursday.
In terms of performance (for the 5-10 laps the buggy lasted) it seemed on par with the Nitros, I was trying to be cautious as to not break anything. I let a nitro guy try it out (I wanted his opinion as to performance) and he was in no mood to be cautious (both broken parts were from him).
Hopefully Thursday it will be more reliable and I cam come back with useful data (motor temps actual competitiveness vs nitros) ect.
