Bob and I discussed brakes several times, but I didn't really know how to build them and they're not in the original plans. So I thought I'd just fly without them. It was after Bob's first taxi test, with a significant tailwind ;) that it became obvious that brakes would be a 'good idea'.
After a few attempts, I finally found an arrangement that would fit under the wheel pants and didn't require re-designing my landing gear. They're not as powerful as I'd like, but I think they can be modified without being redesigned.
