5yrs ago I used to fly RC-planes and now I have restarted again after the break.
Back then I had ARF's and now I also have a few ARF's, I have never built a kit because I've been afraid of the covering.
I have discovered covering now

and are ready to build a kit... I bet it'll be better than any ARF with some tlc.
Is SIG considered to be the best kits for a beginner builder?
What comes in the kits? any hardware at all or only 1000 pieces of balsa?
How processed are the wood parts, ready to glue or do I need to cut them out with a paper template and sand them?
Does the instructions come in metric as well?
I have a hard time understanding the measurments when it says like "4-40/8"
If I should choose SIG, can you grade these three for ease of building, covering, flying characteristics
1. 4*40
2. 4*60
3. Something Extra
(The dream would be to build a Top Flite Spitfire in the future.)
