The 4* is a great plane, the kit builds light and easy. Repairs and maintenance are easy and the open cheek design make it engine adjustments a breeze.
It is very aerobatic , but also can be forgiving at slower speeds. I kit built mine and it went together faster than any of other kits I`ve built.
This plane is flown more than all my others put together , so it gets hammered on pretty hard and often. The landing gear has held up well and believe me ,I have tested it . Have a Saito .56 and 12x6 APC in mine and it seems to be a perfect match. But beleive a good .40 or .46 2c would work too.
The 4* has been around for many years and there is a reason why they are still being built today. Get one, you wont be disappointed. I can not think, of one bad thing to say about it.
