I don't know where they come up with 1/7 scale, I'd say it's closer to 1/8 or less. The bigest I wheels I thought I could fit without modifying the wing was 2 3/4. I had to make up some wheel wells, the stockers are small like the wheels. I found it still wanted to nose over, partially from the small wheels, and partly due to the landing gear being a bit weak on the stock retracts. I shimmed up the back of the retracts to angle the gear forward a bit. It helped. I had a bit of a hard landing off field when my motor died, so I have a little work to do before I fly it again. Keep that nose weight in mind when putting it together. Get the weight forward all you can.
