I've been seeing a lot of videos with regards to those 14mm to 17mm extenders falling off, even while using locktight. I was going to get those for my own Big Rock, but I think I'll invest in a proper 17mm setup. Great video by the way! Congrats on breaking 80mph.

@HardcoreRC 3 года назад

Have the M2C 17mm Hex adapters and apart from the first time i used them and didn't really let the thread lock set we have not had any issues, even had this car up at 105mph and had many many very fast passes and not one issue. The issues people have been having is either not fitting right or not letting the threadlock dry long enough

@@HardcoreRC I know it defeats the object a little but do a run off cam if necessary without the shell .. it will be more aerodynamic. . Reckon u will get 86+ .. the drag with air pressure build up in the back of the shell would be like driving your car with windows wide open at 150 .. the air pressure will prevent u from being slippery through the air . Think u got plenty of power but will need to clean up the airflow will also help if u gear up to keep the motor spooling without drawing a load of amps .... all eyes on you mate ..
