I bought the airframe as is from someone else, so I’ve never flown it. I believe he had a DLE 55 on it. I was going to put an RCGF 70 on it. That engine fits completely inside the cowl without cutting it, and I was going to fill in the current cut outs. Yes, it does have the standoffs still in it, it also has a fuel tank and an ignition battery in it. I’ve not looked that closely at it, but it looks like a large Nimh pack...maybe a 4000mah?
