Is the distance from outside to outside of the lower part of the fork 123mm? If not 123 +/- 2mm the fork itself is undersized. -- Bill Naumuk Zen/Vair 601MG

    Hi Bill, I recommend you use a set of Michelin S-83 3.50 x 8.00 tires for the running gear. Image link below. http://www.macsmachine.com/images/wheelfairings/full/fairingbrkts.gif The tube and tire setup on the Matco wheel is a good fit and at 25.5 psi, rolls nicely. These are good for HDS loading, mine at 1300 lbs max. Obtained or ordered from motorcycle shops as a "motorscooter tire" for around $40.00 each. Good value.

Here is a link to a drawing of the original wheel. http://static.veracart.com/matco/item_pdfs/2627/document1.pdf Hope this helps. Jerry 601 HDS P.S. Like Larry I have converted to the Michilen tires.

    Hi, It seems that autogas attacks O-rings in quick drains, something avgas will not do. Possibly, the addition of ethanol to autogas started some years ago accelerates the deterioration process. As a fix, - quick drains should be used where O-rings are easily replaced. Yes, there are some models where the entire quick drain must be replaced, as proved to us recently by an A&P in Goodland, KS. The occasion was the discovery of a badly damaged O-ring in one of the quick drains of our plane. Fortunately, we have a version where O-ring replacement can be done. - monitor the deterioration by watching the up-travel of the fitting when fuel is sampled. When the amount of up-travel is significantly different from that with a newly installed O-ring, replacement of the O-ring should be done. Equivalently, the distance from the lower fitting of the quick drain to the wing or tank can be measured, and a significant increase indicates deterioration. >From now on, we will check for this condition once a year during the annual inspection. Given our recent experience, replacement of the O-rings every 3-4 years can be expected. I would be interested to learn whether others have had similar experience and/or have found better fixes. Another Digitrak experience: The Digitrak autopilot calibrates everything when the unit is first turned on, typically on the ground. If the airplane is moving forward in a slight turn at that time, the autopilot later is unable to hold a heading, and will always start a turn when engaged. When that happened to us for the first time, it was quite disconcerting and looked like a failure of the system. The fix is simple. Turn off the autopilot, fly straight and level as smoothly as possible, and turn on the autopilot. Within a few seconds the calibration is done, and from then on the autopilot functions correctly. Last but not least: We had a great trip to Rocky Mountain National Park, escaping the record heat in Texas.
