What kind of gearing are you running? I plan on purchasing a mmp and some 3s lipo's and was gonna try 12/46 gearing. 2s is too slow for my track and my lhs

Welp, its all up and together now.

Went with the MMP / 3800kv system. Initial impression on 2S was too slow for any type of bashing. Horribly slow in a larger open area. But 3S felt okay. That was with a 14t pinion, I stepped up to a 16t and it was better, Temps are very happy on 2S and 3S with the 16T pinion.

Different perception at the track! The problem was the tires simply spun in the med. length grass. On the track the 2S gets up and goes and is plenty good for the small track I run it on. Can get ham fisted with the throttle and its never too much power. I do however want more power for those "power to pass" bits. There were times I simply couldn't set it up right and overtake cars by using a better line. It just lacked the power to do so. It really begins to shine on 3S though, there is enough power that you can visibly see power getting wasted on ballooning the front tires. I'll have to play with the diff oils to see if I can find a happy medium. its possible the diffs are simply greased right now. 4S is out until I sort out its power delivery, all of it would be wasted on the front tires anyways.

Steering is good, it holds its line well, but I want more turn in out of it. It pushes too much on the stock setup, I'll experiment this weekend at the track. To get the nose to dive into the corner I have to get off the throttle and dab the brake to get the car to rotate. I'll have to play with the suspension to see if I can make it turn the way I want. It could also be the tires, they are just straight up pin tires.

Yeah I'm running a mmp, 1410 and 3s in my hyper and it balloons my tires really bad. I'm running 5/10/10 right now, but gonna change the center to 15 cuz its really bad. It was really hard to control on the track down the straight and even jumping it cuz the tires turned into pizza cutters

How did you find the stock diffs? Are they fluid or grease filled?

I bought mine second hand and the guy had already changed the fluids, but I did it again just to be sure. 10k in the center is still too thin
