I have wanted to build a Sig chipmunk for the last 30 years and I finally decided to do it. I had been told the kits had pretty crappy wood and it did not disappoint, but you have to start somewhere. I molded a carbon fiber cowl from the plastic one supplied, came out pretty nice, replaced most of the sheeting and built up the horizontal and vertical stabs to save weight. I also built up the wheel plants and plan on glassing them.
Just a few minor changes: made equal wing panels, enlarge stab slightly and lengthened fuse slightly.
Just an example of how heavy the ribs where, I opened up the back end with a dremel tool....see pictures, that alone saved a 1/2 ounce, the wood hard as a rock. Another funny item is some parts where die mashed...others laser cut.... and they did not match the plans. Nothing like buying $ 50 in wood to replace wood you bought in the kit
Oh well, I wanted a chip
This will be an electric with an eflite 15 and 4S battery TBD on the size.
Here it is so far in the bare bones, will be silkspan and dope to the scheme on the box. That scheme makes the airplane in my opinion. Hopefully will be done by Brodak
