Scout has the Bill Rewey toe brake setup and I love it. The brakes are off ofa Cessna 172 so they have plenty of authority, plus the airplane has 6.00x6 Clevelands,not large-diameter spoked motorcycle wheels/tires, so I have no problemstopping, turning, steering, or anything else... and the brakes never evenget warm in a hard braking landing situation with partial power on, in the middleof summer.I'd like to point out one thing about heel- vs. toe-brakes with the stock rudderbar arrangement. In general, I like heel brakes but that's probably becauseI cut my teeth on them on my early training in the J-3. That was with conventionalrudder pedals though. Recognize that when you have a rudder bar and notpedals, the geometry is all different. With pedals, your heels are the pivotpoint for rudder actuation so sliding them laterally to engage the brakes doesn'tinvolve a large change in geometry. With a rudder bar, your heels are constantlymoving as the rudder is moved, so heel brakes are a moving target. Mike Cuy and others with heel brakes, please chime in here- but I find that thetoe brakes with the rudder bar are quite easy to operate and get used to. Notso sure about rudder bar and heel brakes, but I suppose compared to the gyrationsthat the Wrights had to make to fly their wing-warping wonders (while lyingon their bellies-!), we have it pretty good.In closing, I will say that the brakes on Scout are so effective that in a verystrong headwind and with the brakes locked, the plane would probably skid backwardson dry pavement before the brakes would slip. On grass or wet grass, itwould skid even sooner. Corky did a good job on wheels and brakes!--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: build update
