MAK Dynatron Heli Holder
The Sullivan Dynatron S603 is very popular, heavy-duty starter for gas and nitro RC model engines. Combined with Sullivan S613 Helicopter Extension Wand it creates great set for nitro helicopters, easily able to start 90 / 105 class nitro engine and which will last decades of usage.
Unfortunately plastic holder parts provided with the Dynatron are very basic and do not allow to mount the battery in compact, convenient way. That’s why I created my own holder, able to hold both battery and heli extension wand.
