I got a question....
I have the 7018 controller. I want to brushless my e-maxx. Could I get away with using it.

Currently I would like to get maybe a 10-20% speed boost from stock. and also gain run time if I use use similar performance. At the start I would like to just continue to use my current packs. 6 cell 3300's thus it would have to be a 12 cell system. Later I would like to change the pinion's and move up in voltage, At that time I may need a new ESC but would like to re-use the motor.

I guess what I am wondering. Would a 7XL be a step up from stock with 12 cells and would it be able to run on a 7018 controller. If so what gearing would be recommended for this truck. To make this more interesting I use oversize tires. (Hot bodies) Thus I am sure I will need a smaller pinion. Currently I have the stock 18 tooth, 16 tooth, and 14 tooth pinions in my parts box.

PS.
I also have a huge hacker, But I am sure the KV is so low that I would need many momre cells to make it work well. So for the moment I am not planing on using that motor. (b50 15XL) I think, so mnay things laying around I forget without checking back to old info.

u can.. but its not recomeneded. Ur better off buying a 9920. U can try, butt theres a risk taht it might burn up!

The 7018 would actually be better to use with higher voltage and a slow motor. If you use a lehner basic 2400xl or 2800xl, the 7018 will work quite well. I would use a fan on it for sure, but it is a pretty tough little controller if used within its limits. The 9920 is a better choice, though. I wouldn't get too aggressive with the 7xl and the 7018 controller. It will run it, but keep the gearing conservative.

I thought that was a 12 xl or something. I ran one of the 7020 on a 7xl. The 7020 is no longer with me. RIP If I remember correctly the kv was 1100 or so. A stock motor is only about 1400. The 7xl is alot more motor than stock titans. You could run the hacker on the truck with 22 pinion and 66 spur and have plenty of power and run time with out worries on 7020. That is what I think.

Rene,

Yes Patrick got his broken controller replaced by hacker's brand new one. Allthough it look's ugly it is butter smooth.

One thing I would do is throw some heatshrink around that puppy. Don't want to get loose dirt in there that might be wet causeing unwanted shortage.
