Default RE: Building a Dynaflite Super Decathlon

Well guys,

I finally got around to balancing my Decath last weekend. I plan to take a week's vacation maiden the Decath. Have had one issue after another the first half of the year and have not been able to do much in the way of building or flying [:@]. I normally begin flying in March or April but this year my first flight other than a little foamie out on the farm will be next week. Anyway... I removed the cowl and had to epoxy 8 oz of lead in the very front of the cowl to get anything close to a balance. Looks like it's balancing at 3 and 7/8 inchs, which is the maximum rear balance in the instructions. I don't like to maiden with a rearward CG but I'm going to on this one. Hopefully it will behave and not be a 1st flight of stark raving terror . Since the plane was so tail heavy and I had to add so much weight, the plane's all up weight is 18 lbs and 9.6 oz. I took a picture of the weight in the cowl and attached below. If I hadn't mounted in the very front, there's no telling how much lead I would have needed. I noticed nh4cio4 also added 8 oz on an earlier post but I'm not sure what his all up weight was. I'm thinking, installing the tail wires hurt me in the weight department. Maybe I should go back and remove them. I would think with the engine I'm useing, tail heavy would have gone away but not in this case.
After I report on my maiden, I will be finished on this thread but if anyone adds to it I'll check it from time to time. I plan to start monitoring mattnew's new thread as he started one on bash and build of the Super Decath.
