one of our better TC drivers got his Spectrum sys and sold it the following week. i asked him why about it at todays race. he said in mod TC he noticed a lag in throt response. he had others try it and they noticed it to. he went back to regular FM stuff....lag is gone.
he uses a M8. i have plans on getting a KO Helios and was considering this system, but now have doubts
this is a documented and fixed issue with the original M8 units and if they are sent back will be updated/upgrade with the latest software that corrects this problem. you may want to read about this further on spektrum site.
