I've had this project shelved for nearly two years! I could kick myself for taking this long to finish it.

Long story short. I built a Goldberg Electra kit about six years ago. Great flying electric glider. Back in 2007 I tried to catch it and ended up snapping the wing. In a way, it was a good thing as the plane desperately needed spoilers and the wing needed more reinforcement. I found a kit (hard to do) and built up a new wing. However, when I started designing the spoilers I kept changing my ideas around and finally just put it aside.

In the end I decided to go back to my original idea: Install 9g servos into each wing and just use their arms to push up the spoilers. The area is small and every thing I tried to 'link' the spoilers to the servo failed. I could have spent more time investigating other ideas but these are working fine...so why mess with it?

The pre-cut ribs in this kit left HUGE gaps between the spars. I brushed on small amounts of Gorilla Glue and water to fill everything. You can see some of the 'foam' in the photo. This wing feels MUCH stronger than the original albeit a little heavier.

Hope to have the wing covered by Wednesday and at the field on Saturday.

I won this last year at BEST 2008. Can't say it is a popular RTF as it is made from plastic and runs on a brushed motor.

However....

This is actually a fun little plane. Not a great plane by any means but sometimes you find a product that serves you well and keeps on going. I've actually torn the wing off of this plane on one of the first flights but was able to repair it with Gorilla Glue and tape. Got right back in the air without any flight performance changes. And what do you do when the box doesn't include the clips for wing struts? Cable ties!

One modification I made was adding an eye hook and rubber band to help the main landing gear from flexing. Doesn't look great but does exactly what I need. Oh yea, and chunked the NiMH battery for a 2S LiPo. 2-3 loooong flights without a charge.

Thought I'd share a positive experience with everyone today.
