    Broad new UAS rules proposed today

    The NPRM proposes harsh new restrictions on model airplane flying that will effectively outlaw the activity within a few years (via elimination of flying sites). AMA and EAA have already taken a strong position against this NPRM. If you feel strongly (as I do) against this NPRM, what you MUST...

    Broad new UAS rules proposed today

    The FAA is under no obligation to consider any of the comments we make to the NPRM; we have seen many times in the past that the FAA considers themselves more expert and more knowledgeable than the airspace users they regulate. The only way we can have any voice in this matter is to immediately...

    V - Witt / Witts V

    Mike, seeing the photo of the wing drawing reminded me of something that happened when I built my wings - I ordered four sheets of 1/16th thick 45 degree aircraft mahogany plywood from a reputable east coast vendor, and when the crate arrived by truck, I was upset to find that they had shipped...

    Steps to scratch build a VW

    Yeah, we would sometimes hear a 'warble' when doing a full power ground runup, interestingly the warble didn't occur in flight. I'm in the process of converting some old Formula V VHS videos to digital and will watch for an example of what we heard. These videos will be posted to YouTube in a...

    Steps to scratch build a VW

    Sorry, I haven't been following this thread last summer... about Wittman's prop drive approach - he wanted to use a cut-down aluminum prop for best performance, so he took a J-3 Cub metal prop and whittled it down to a toothpick in planform. (FV grandfathered Wittman's metal prop but otherwise...

    Wittman v-witt flying experience

    TF, I'm sure flaps down stalling speed was lower, but I don't have any specific numbers for you. Charlie Terry did all the test flying and he's no longer around to answer that question.

    V - Witt / Witts V

    This is Jim Vliet checking in. I can answer most questions about the V-Witt, Sonerai-1 and history of Formula V air racing 1977-1999. A couple of safety recommendations - 1) please always wear a safety helmet when flying a V-Witt. Out of about 10 that have been flown, 3 were involved in fatal...

    Wittman v-witt flying experience

    I built V-Witt N33JV "chasin' rainbows" with help from Ed Fisher. Wittman put flaps on the prototype V-Witt because he wanted to be able to land in any small field in an emergency. We found they were useless and also found that we ran out of up elevator with the flaps fully down! Neal LaFrance...
