I had 100+ flights on mine and imo the best overall motor at this time would be the wren ss. I had a cranked up P-60 which flew the jet fine but was a little bit of a gas hog considering there is only 70oz onboard. The Tams A-4 is a good flying little jet but needs to be as light as possible, adding bigger motors and more weight is not the way to go.You are just asking for trouble, this is not a big jet. Eddie P pretty much covered the flying part of the A4. With wings level on final she is a very easy and predictable jet to land.
