It's been a week or two since I updated the Scooter fans out there on our progress. We ran the A4 2 weekends ago and had a samll hydraulic leak that needed attention prior to our next run. We found that in the R/H speed brake area and fixed it last weekend. We were able to tighten a fitting and that took care of the problem. Interesting enough, the manual does not want you to over torque these fittings as they are made out of aluminum and will crack if too much torque is applied. I replaced this fitting quite a while ago and didn't crank down on it too much thus the leak. Not much room for there to be an oops with the fitting.
Today we went to Oshkosh to prep the airplane for full power runs tomorrow. We serviced the oil, hydraulics and changed out the main wheels with our overhauled wheels and new tires. The old tires were not really safe enough to taxi or pull power with. Later in the day we pushed the Scoot outside and set up for another idle run and if all looked good a short taxi with brake checks. Everything went as advertised. I know something will come up and cause us some grief, but I am amazed at how well the systems are responding the more we exercise them. The fuel quantity problem I had on the first engine run has cleared up and it is indicating as it should be. We'll keep our eye on it over the next few engine runs to make sure it doesn't come back.
Here's a few pictures from today and we'll post how the power runs go when I get back from up North tomorrow.
Taxiing this little beast is quite interesting. I now know why the nose strut is bouncing so much during turns as you have to apply a fair amount of power and hold the brake and bounce the nose to get the nose wheel to caster the right direction. Today our A4 moved under it's own power! It's getting pretty exciting.
Thanks for following our progress!
