I went flying my KB3 this weekend at El Mirage for the first time in awhile. I made some changes over the winter, a bracket on the tail had cracked and I put some bigger tires on. I did a good preflight and I thought it was ready to fly.
I taxi out prorated and started off and it did not want to rotate onto the mains, after about a half mile it finally rocked back on the mains. I was confused why it took so long to rotate so I balanced for awhile and it was all good so I took off and it flew great. After the flight Pete a gyro pilot said my gyro looked like the tail was too far in the air when I was taxing back. I mentioned that it took a long time to get off the ground. We came to the conclusion that by adding the bigger tires it changed the angle of the gyro, probably 2 or 3 degrees. Not a big deal once it is in the air, but 2 to 3 degrees less AOA made a big difference on take off.
I will probably put the small(4") tires back on. I like the way the 6" tires handle the dirt better, but I would have to change the axle to go with them.
Little thing mean alot.
