Note: While performing this modification, there is still a slight possibility of the Rx's MOSFET circuit getting damaged. By doing this modification, www.rtf-heli.com is not repsonsible for any Rx's burning out. One way to minimize the chance of the MOSFET circuit burnout is to install the FUSE MOD before performing the below MOD.
bought at your nearest hobby store or Radio Shack. Why do this modification ? After installing the super skids 300 landing gear system, the heat sinks on the main motor and tail motor, metal flybar rods, metal tail boom struts, metal rotor head core, titanum tail boom from super skids, ON/OFF switch, etc, -- the heli weighed in at about 13 ounces. A standard 7.4 volt LIPO could not lift the heli more than 2-3 feet above ground. The solution was to get a bigger 380 carbon brushed motor or use a larger battery. The problem with a 380 motor is that its RPMs are too high and will cause spinning as the tail motor cannot compensate. Using an 11.1 volt LIPO can cause the Rx's MOSFET circuit to melt at leave the Rx inoperative. The receiver is about half the cost of your four channel helicopter. We have limited the chances of a burnout with the below modifications. (Note: This modification will also still work using using a 7.4 Volt LIPO but lift problems will still be an issue)
The main motor is a 370 carbon brushed motor w/11t pinion 0.5m and is a direct replacement for the main stock motor. The main stock motor is a 370 carbon brushed motor w/10t 0.5m, which is tight on the main gear and really makes the Rx heat up. The 11t is smooth and makes the heli purr like a cat.
MOSFET in the Rx upon lift off because the main motor and tail motor have more teeth causing little resistance on the gears.
