After a long time of research and experience accumulation, we have created a starter for the large gas engine RC airplane.  This starter can start any engine smaller than 300 c.c, and make the whole RC plane hobby fun and safe.
Anyone with RC plane experience would know that the propeller of the RC plane is very dangerous. Without the assistance of an engine starter, spinning the propeller by hand is almost unavoidable to hand injury, of which we believe than many have heard of the similar stories of fellow hobbyists. Now with the aid of the large size engine starter, be afraid no more.
Besides, even with the most excellent designed and built engine, sometimes it would fail to start.  With the aid of a large size engine starter, one can start the engine in a second. If the starter can't start the engine successfully after a few seconds, one can check on the details of all engine parts immediately, instead of starting the engine for a half-hour by hand and checking the system afterward.

Here are the specifications of the MORPOWER large RC plane engine starter:
weight:  7 Kg.
voltage:  12V
maximum current:  350A
maximum power:  4KW
*Reversible rubber cup for both large and small size spinners.
