i was testing the new sofware 110stock and for me it was a big diffrent in in top speed and punch. iam running FDR 4.5 on a xray T2 009. and now i almost kan keep up with the Advance blackdimond and Tekin Ecs on the straights. Running the Sp v3 17.5 motor. But cant compete with the castler creation mamba max pro, not even close. Temps on motor around 67 degrees celsius after a 7min run indoor carpet.
