Have'nt bought any yet as i'm working through other issues. I was told by an employee at ZAC that the 30# rating is supposedly used for the 750. I dont know if the 750 uses the same bubble doors as what's offered for the 701, perhaps the fellow enthusiasts constructing the new 750's could help [Rolling Eyes] I know I will fab the door bracket to assure door is forced closed to prevent "accidental opening" by having the spring go over center at the near closed position. The length of this bracket or "arm" should'nt need to be much. I recently had my bubble door fall from the open position from the wing sucker, which ended up breaking the back edge of my door because the harness buckle was hanging out of the door opening "just right". The sellection chart can get you what ever range you want. Hope this helps.

If you find yourself in a place that only has regular auto fuel, can it be used for a short period without compromising safety and/or damaging the engine? No I have not had this happen but it is not out of the realm of possibilities.

Best option is to use avgas for topup because that wont cause detonation to occur where low octane fuel will. Whether this damage occurs on a particular flight is not related to duration of running the fuel but conditions on the day such as load and temperatures. With the Bing carbs the most critical phase will be full throttle. Low criuse settings should be OK and with the 701 you can takeoff like that, also the first t/o will be on full strength fuel so youre probably covered in an emergency.

I gained a minimum of 5MPH cruse and upwards of 10MPH cruse improvement is not unusual. I now cruse between 90MPH to 105MPH. Its a very different airplane now; it gains speed much faster and doesnt lose speed nearly as fast now when you pull the throttle. I was so impressed with the performance improvement I decided to market a Wing Strut fairing kit to help pay for my airplane habit. It includes all four fairings and all the hardware needed for the installation for $275. Ive spent a lot of money on airplanes over the years and this is the best performance improvement for the least amount of money I have ever enjoyed. Whether you by my kit or some other aero wing strut solution, just do it, you will not be disappointment.
