Hello all,
So to sum this up, I've been trying to make a very over powered big rock for a while now. I started with a TP 4050 2830kv D wind on 4s. It had a ton of power, but overheated too quickly, and really heated up the esc as well. I then tried an old Castle 1515 2200kv on 4s with a 24 tooth pinion and got 57mph with much better temps, but it didn't feel like it had enough torque and was still too hot for running in grass, not to mention making my battery sag to lvc way too quickly. I then ordered a TP 4060 1730kv, and ran it on 5s with a 24 tooth pinion. This motor gave enough torque, but it also heated up too much. After about 5 minutes of runtime in grass it was at 180 degrees. Since then I added a fan, and dropped the pinion down to a 20 tooth and now I barely hit 130 degrees, but running that big of a motor and 2 batteries for 5s just makes the truck too heavy.
I'm just very confused by all of this, and not sure what to buy for the final motor in this truck. It's very odd to me that a Castle 1515 was able to push the 24t pinion and the TP 4060 was not... i was going to look at the TP 4050 2100kv, try it on 5s and hope that it would lower the amp draw, but since it's bigger brother had problems pushing the 24t around I'm thinking it might as well.
To summarize, I've tried a bunch of setups I thought would work and get me to my goal of 60+mph on and offroad without too much heat, but nothing has worked thus far. Are there any other options that I'm not thinking of?
Thank you for your help and advice!
