Stef; you may want to investigate motorcycle muffler/silencers that slip inside the end of your exhaust pipe. For example: https://www.revzilla.com/motorcycle/vance-hines-big-radius-quiet-baffle-for-harley is one that will fit inside a curved pipe. I can't tell whether the end of yours is str

Stef; Here's a suggestion. In our business, we have a number of very accurate instruments and one of them is a sound level meter. It is calibrated and we use it in our engineering work for measuring sound levels from equipment. A couple of years ago I was checking something with it and decid

Well said Pat about trimming, and I really like your metaphor about driving with "front wheel alignment" issue on trimming of an aircraft elevator during flight... It took me quite a few hours of flight training to learn and understand trimming, and I could have learned it in less than 10 minutes i

hi stef, thank you for the update. nice to dream of something other than these four walls and bad news on tv. what is the top speed and cruising speed? do you like that engine choice? as far as nose down, thats interesting. the reason canard designs are more efficient is because both wings are l

Dr Hsu, As you advance through your flight training, your instructor should teach you about trimming. You don't trim for attitude, or weight and balance, you trim for airspeed. And the main purpose for trimming is to relieve the stick pressure from the pilot while in stable flight. Every speed wi

Hi, The weight and ballence is perfect, we made the fuel tanks in the leadingedge and this works perfect. But the elevator is a bit heavy, so the springs pulls the elevator up. To fly the first Test hours I installed A fixed trimtab. But now after 15 hours on the airframe I found the solution i
