A kit gives You more control over weight and strength of the finished plane. And allot more to worry about"

If You have had 4 ARF's and You are still trying to decide on a kit, then I would guess that You will build a kit sooner or later.

Question

Is one of Your ARF's still flyable but needs little work? You could take the covering off and look at the construction, You may see things that You would re-do or improve. Use it to practice covering, and if You mess up You can take it off and re-do it.

It would cost a little for the covering, but it may be worth it to get an idea whether You will like it before spending money on a kit. Or You could get the ARF and still practice covering if you are worried about it looking bad. an extra $20 for trial and error?

The kit You listed I cant help You with, But kit building today with laser cutting and well printed manuals and plans is an easier experience. Depending on the kit, some are very easy and others have hundreds of pieces and lots of shaping. "Like the Corsair"

Good Luck with Your decision
