I do not know why a lot of people seem to think CDI is the only way to go. I have had trouble with 3 of the 4 RCXEL ignitions. I never had any trouble with my mag ignition systems even when used with a none 2.4 radio system.

You may want to cut the extra gasket off by spacer & paint the cyl red or black. Guys seem to like "pretty engines" Go figure that!

Another good point though, with a mag a lot of extra wires, a switch & a battery for ignition is eliminated. Also no need to charge a extra battery & the expense of buying a extra battery.

For reliability you cannot beat a good quality engine like a Echo or similar with a mag ignition. If and when a real small mag ignition comes out on the market...most all people will be using it. Hope some guy understands this and buy you good engine. I know AV8TOR would not sell junk. Its a certain country that does. Very few good brands built there. Capt,n
