RE: Best first KIT PLANE???
G'day
Another vote for Sig Kits.
I currently have the following planes built from Sig kits and all are great -
Kadet Senior (excellent large slow three channel trainer but lots of building in it), Kadet LT-25 (very easy build, flies really well with a 30 four stroke), Four Star 40 and 60 (nice to fly and super easy to build if you follow the instructions), Somethin' Extra ( great fun with 30% expo to tame those large ailerons).
I also have a couple of Sig ARFs but I think the kit versions are better as you can cover them better than the ARFs are.
Enjoy your build. I am sure you will.
