Call Bruce Tharpe at BTE. When he worked for Sig, he re-did that kit to improve it. He details that on another site, but since the competitor police are lurking around here I'm not sure which links are "okay" to post and which are not. I had thought RCU was past all that nonsense, but apparently not.

And they also zap offending links in PMs. Tried that last night.

But if you'll look for "R/C Flight Unlimited", under kit reviews, you might find it...

I was thinking about this one myself, and ended up with a vintage SkyBolt kit I found on FleaBay. Both of us have our work cut out for us...
