I noticed with my big 2280, I had to do the same thing, although it was free spinning... it Still had to give it a little throttle to keep it levelled just because of the size of the motor... I only had this problem with my E-maxx and Mayhem buggy... ALl the other nitro to electric conversions were okay...
I think if you are used to driving a Neu powered vehicle you dont even notice it. The only reason I noted any difference is I switched from the Hacker to the new and tried it 10 minutes later in the exact same setup. I only rn one pack with the Neu before going home. I was just trying to see how the powere of the Hacker 10XL and the Neu 1512/2.5d felt back to back and geared for the same speed.
Its a very easy compensation to make and if you are used to driving it that way and Lehner of Hacker may seem light in the nose to you.
I can't decide if its more fun
to make it...
or break it...
