Convert your 45 to EI via Ralph at RCIGNITIONS. DA and 3W are both excellent choices, but why not save some money and get some great life out of your 45 since you are just getting started? EI and a good exhaust system will go a very long ways with the 45, and narrow the 'worth it' margin when contemplating the purchase of a new engine.
