Austin,
For the speed limit, in the section about the belly board that was added to my Q-2 construction plans, it says: "We recommend that the board be deployed at a maximum of 110 knots (126 mph). After deployment, a maximum speed of 130 knots (150 mph) should be observed."

Richard,

I have the airbrake mod installed. Hadn't heard of the engine fume
problem previously. It seems to be plumbed in pretty tightly but at
100+knots air can get anywhere i suppose.(i don't know if there is a
speed limit on it's use)

Does anyone have any answers on this subject?

Austin
