I thought that I would post a pic of my partialy complete Sopwith Pup. This is a self designed and scratch built effort. The wingspan is 30" and will be powered by a 280. I drew it using TurboCad and have had to change the plans as it came together.

That's a very nice plane. Can you give more info on the equipment you'll use along with the overall weight? Any reply is appreciated!

A lot of things are still in the air, but I plan to use the GWS 280C motor with a 7.4 volt pack. I will try a 9x4.7 prop. The radio is the new JR Quatro Lite. The airframe will be about 3 ounces when covered. The wingspan is 30 inches and a wing area of 330+ square inches. Due to the large wing area, I don't think that weight will be a problem. I have been advised that the 280 motor may be too much. Due to the short nose movement, I am more worried about balance and getting the G.G. and center of lift right.
Any comments will be seriously considered. I am moving from rubber to electric and have much to learn

You obviously put alot of work into this.
Please do not let this be the plane you learn on. There are many suitable trainers on the market.

Its almost a shame to cover it! Any chance of clear covering?

Too late. It is now tissue covered and has flown. The flight showed it to be a bit tail heavy. I have moved the servos forward as well as the reciever. I was anxious to get it in the air (i am sure others know this feeling) so I tried it on a 5 cell 7.4 volt battery and the esc kept putting on the brake. I have ordered an 8 cell pack. The 280 is hungry. Flew, but without authority. I will continue to develop it for a while.
