TwinStar II EDF Rebuild – Part 1

Today Austin and I started the rebuild of my old EDF TwinStar II. Back in 2011 Todd’s Frankenplane and the TwinStar EDF had a mid air collision on it’s first full day of flight. The only damage was from a direct prop slice on the left aileron. You can see the collision here (1:20 into the video).

Even with the direct hit I had no problem bringing her in for a safe landing. SInce then I’ve had it a handful more times with a horrific looking field repair including ripped cardboard and tape.

Here you can see the prop slices in what remains of the aileron. A good inch and a half is missing and another 5 inches torn. The hinge is completely pulled away for about 7 inches.

First the section of damaged aileron was cut off and a matching section cut from a spare TwinStar wing.

From here we hot glued the new section in. A super thin line of glue along the hinge edge and a glob on the end. After paint the hinge will be reenforced with packing tape.

In the spirit of salvaging and rebuilding we dug out the old Coast Guard TwinStar that crashed after the elevator servo stripped while inverted. This old plane had a ton of flight hours on it. Amazingly the landing gear held up even thou it was just held on by sandwiching the foam belly between the gear and a section of balsa.

So we pulled out the poor man’s landing gear leaving plenty of cleanup. (In a future build I return to the landing gear mod for the TwinStar II with fully laser cut balsa subframe. But more to come on that on another day)

Then we decided to paint the wings to match the fuselage with matching red and blue stripes.

painting complete!

We finished up the day with matching stripes on the right wing. Next up is to reinstall the electronics, patch up the holes in the belly, and head out for some test flights! As soon as we have this bird back in the air we’ll be sure to post about it.
