Had a lot of trouble ground looping cause the wheel would 'break' too easily. In the archives it describes how to fix this and make it custom to your desires. It just requires you to grind the channel longer where the ball bearing rides. Works great. The slingshot with big wheels has a high stance with short coupling. Makes for a wild ride if the wheel breaks and you start sliding. Just my opinion.

Thanx G.Aman " Gary Aman and the group Gary had posted this picture of my antenna attached 'boyd-antenna.jpg' I got to the airport yesterday and what I measured was, the center conductor seemed as best as I could measure "21 1/2 inches" the braid should be just as long but I would have had to remove all the floor panels to measure it. attached are some more pictures of the installation. 'Braid-location.jpg' shows the coax which is RG58 with bnc connector,,, as it goes to the left front of the nose cone. ( the length of the coax is not critical, long enough to reach without kinks and pulls but the shorter the better, the length of the center conductor and braid is critical. with the center conductor length being most critical) also it shows the braid of the coax angling back to under the floor panels. (I had to try different angles to get the best swr. 'antenna-center.jpg' shows the center conductor going up vertical along the left side of the nose cone. and the braid doubling back through the fabric. antennaleft.jpg shows the mid section of the antenna center conductor vertical up the left side and across the top. 'antennaend.jpg' shows the antenna going across the top of the nosecone. the antenna end in the photo coming from the right side is my elt antenna, and the black long rubber duck in the front is my ham radio tracker. with the tracker running, my wife can check my progress on long trips so she does not have to worry. and if the track stops in the middle of nowhere, she knows where to send the search. you can see I mounted the center conductor as well as the braid in short sections of drinking straw siliconed to the inside of the nose cone. sections of duct tape were used in the trials. but with time would fall off. the 21 1/2 inches is the finished measurement + or - my measuring skills while standing on my head, over under around and through the rudders peddles and nose cone. I started with 25 inches and cut to length and changed position of both the center conductor and braid, while using an antenna analyzer that our ham radio club owns. it is not the perfect location and I am sure I could improve radio coverage with an external antenna and a better ground plane. but it works well enough for my needs. boyd young kolb mkiii n1225y ham radio extra n7wfm http://www.matronics.com/Navigator?============= ======== ________________________________ Message 5 _____________________________________ Time: 08:57:39 AM PST US Subject: Kolb-List: Re: Kolb-List Digest: tail wheel From: "Dennis Thate" John, The only time I use my brakes in flight is just after lift-off.

The non-turnable Pizza Cutter tail wheel puts a side torque on the lower tail-fin midway, so when forced into a tight turn, it will break, where as a swivel wheel eliminates this problem.
