Hi boys. It's great to see some kids get away from the video games long enough to have a go at building some model airplanes.
You guys tell your uncle that the 049 is too much power and it'll just get the model into trouble rather than make it fly better. But there is a way to fool it into thinking it's a smaller engine. Turn the propeller around so it's backwards. That means the curved top side of the blades is to the back of the model and the flatter back side is to the front. That'll reduce the engine thrust to a lot closer to what you need to have for a smaller model like the SE5.
Best of luck with the model and the flying in the grass and here's hoping you miss the rock pile. If you want to try a new home for your 049 and you don't think it'll make you dizzy I have plans you can download for a control line trainer. It's called the Cadet and you can download the plans from this page....

The hot link to the plans for the Cadet is down near the bottom after all the free flight stuff. There's been 4 or 5 Cadets built now and all have flown well from what I've heard.
If you want to stick with free flight then go with something larger at about 36 inch span for the 049.
