1512 2.5D vs 3D on 5S?

thanks brian,

and wont the 3d pull less amps under the same voltage (5s) than the said 2.5d so it will be running cooler and more efficent, even though the resistance is very slightly higher, the lower amp draw over comes the other figures in the heat equation right?


and for drift, try your start power at medium and see if you notice any difference. but it could be a ton of things, including your drivetrain, and you wouldnt even know it, your gear mesh effects it, the gear mesh of your diffs is important also, take the pinion off and push your buggy on a hard floor, if it doesnt roll 4-5 feet "Silently" with a very light push then id be checking there first. did you check your motor bearings for any play?

my gear mesh was too tight on my front diff awhile back after i redid (too many shims on the wrong side, and my motor was running a good 20* hotter than normal after i fixed that my temps went back to normal.

another thing to look at is it really doesnt matter that the neu is up 170-180 they told me their motors would run fine all day long at these temps, so check your temps and sceduled stops through out your run and after it gets up to 170 see if it goes anyhigher as you continue to run and find out where it tops out, in our 30 minutes july 4th a main my 1515 was running 175 at 15 minutes and at the end of the race it was 173, they will top out like this, and nue told me as long as its below 190 its fine to run them at that temp as long as needed.
