RE: SIG 1/4 scale Extra Question
I have one as well, powered with a zdz 40. It is an excellent flying plane and high quality all around. Like any arf though it does have a couple of issues. On mine I noticed that thee was very little glue used on the exposed joints so I went over every single joint on the plane that I could get to without cutting up the covering.
The covering on the plane is Ultracoat. The white on mine matches the roll I bought perfectly the black does too. The plum, purple or whatever came close but not a complete match. I servo'd mine with Hitec 5645 and 5975 digitals and so far am extremely happy with the plane. Flies the pattern beautifully.
Those who have used a glow motor have had to add weight to get it to balance. I didn't have any balance issues with mine at all.
