Go gas and don't look back. I did it and I have zero regrets. The initial cost of prop jigs, ignition batteries and the engine will be well worth it. Dead sticks are fewer and the reliability is awesome. No more glow plug igniters, glow plugs, starter boxes, messy cars, planes etc. Gas engines are simple and straight forward. The fuel cost savings is enough reason alone to do it. As far as electrics? If you're into having dozens of expensive batteries(which constantly need replacing after too many charges) multiple chargers, regulators, ESC's etc more power to you. Keep it simple. The most valuable advice I can give you in this hobby is..... Reduce any and all points of possible failure. How? By not having unnecessary BS going on inside your plane......
