Good Morning folks, I have been silent about the taxi testing, but what i see is everyone talking about the handling charatristics of the plane as it relates to testing. I did probably 100 taxi runs on 357CJ. I never ever thought that it was about handling after a couple runs. It was about the engine. I had originally built a snorkle for the fresh air to carb and it was not the right thing to do but only became know by high speed taxing. If I would have taken off in the original configuration I most certianly would have been a statistic....Do as you feel good about as you are the pilot in command but as for me there will be high speed testing done in the next several months again.

I have done both high speed taxi tests with wings on and wings off. If you are doing this wings off, remember that the stub wings create enough lift to pull you off the runway without ailerons. Be careful out there.

Never thought it was an option. And we can guess forever if it is smart or not. For me, I am getting closer, but we do have a professional at our airport and he will do the first flight. If anything goes wrong he has a better shot of handling it than I would. I will do taxi testing and maybe some hops, but not a flight off the airport. Not the first one. Ray_pilot New Orleans ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ I don't recall anyone suggesting not to do high speed taxi test. My observation has always been "do high speed taxi test to determine control-ability of the aircraft up to lift off speed, maybe two or three runs." Anything beyond that I consider "practice" and not "testing" and any "practice time" is simply additional safety exposure. If you need "practice" time, your suggestion of having a more qualified pilot do the first flight is good advise. Everyone makes their own determination on whether they are qualified to do first flight. Some times it works out, sometimes it doesn't. Without checking the records I seem to recall an accident will most likely occur on landing and / or "crow hops" rather than takeoff . Go with what makes you feel good, until it doesn't feel good any more. 🙂 Larry Flesner -- KRnet mailing list KRnet@list.krnet.org https://list.krnet.org/mailman/listinfo/krnet
