It is also when it have to go up over small obstacles such as doorsteps...said in another way it had more power when it had the RX-18 mounted...and I was told it would have the same ore more power when it got the SLU...

But what I can't figure out is, if there should be a fault in the SLU-esc such as a blow FET it would show up as a fault when either reverse or going forward...but it can all the movements....
It just moves as it was running low on battery, but that has been checked...have tried with three batteries all where charged up and had a out-put voltage from 8 to 8.4 volts...

I have also tried to callibrate the radio once more, thought it maybe did'nt send out full trottle signal when used...that did'nt help...then I changed the radio and the receiver to see if that maked any change...but no luck there either...so now I am pretty much out of solutions...
