Gday,
Now I am trying 25/93 gearing and foams. I have the car at exactly 1008 grams with 40 grams of lead added. This is with HobbyKing 3000MaH 2s - 30/40c lipo. I think the car was really designed for the 7.2v NiMh stick pack with the extra weight??
Anyway, I am progressing steadily and falling in love with rear wheel direct drive, lol. First I went backwards by putting the powerful Castle system in it. I should have started the stock way, learnt to drive an F1, then put the Castle Combo into her. I am only getting more excited.

I got a bargain on the 04 module pinions 20 & 21 when she goes brushless with 5700kv. Standard pinion on F104 Pro is 25.
So for now, the Mamba Pro is in a Mini Losi Slider with RZ300 running G3 3s lipo. It is a beast.

When I am happy with performance of the F1, and my driving, I'll make her brushless.
That's it for now, more photos.
