Has anyone at the factory seen the new T3 Tailwheel Suspension system? It is claimed to be lighter than the Pawnee spring and looks like it could be much more effective. Mitch/Pete/Randy any thoughts for use on an EX?

Looks really cool. My last Carbon Cub had the baby bush wheel and it "shuddered" a lot. I ordered my FX with the 3200 but this looks interesting.

If you read this post yesterday I had to make a couple of correction today to the measurements in this post, such as tail spring widths and tire size, I did some measuring this morning and confirmed the measurements below are correct.
Bruce, I'm using the three stack pawnee spring(1.75") and I had to take about an 1/8" off on each side of the spring to fit the Tundra Lite wheel receiver. If you have access to the 1.5" three stack cub spring it would fit with no modification. The wheel I'm running is an 10" dia and 4 or 5" width. The actual tire surface on the ground is as much or slightly more then the 12" babybush because of the flat profile.

I'm checking with them to see if they can adapt the rear mounting point to match the spacing on the EX. Once confirmed I'm going to order it and give it a shot..

Looks like it would really reduce the tail fatigue if you are doing lots of high angle of attach landings and with the two cylinders it should eliminate the shimmy on the Babybush tailwheel. The down side for me would be the fact it looks like it substantially reduces the angle of attack on the ground which is what I want for short field take-off performance. I've got the shimmy problem solved with a Tundra Lite tailwheel, if you don't mind a spring-less tail wheel, which is manufactured in Aberdeen, Wa by Jim Pekola (http://www.tundratailwheel.com/)

The only thing that prevents true tailwheel shimmy is proper "positive (leading)" deck angle of the pivoting plane of the yoke. If there isn't a stop limit on the suspension that prevents it from going past that positive angle to a negative (trailing) one, then you can and may still experience shimmy if the struts let go for some reason.
Hi Steve, can you tell us about the spring less operation, is it much rougher on landing / taxying than a spring.
I have a Baby Bushwheel which works well but is heavy and I have had a couple of loops which I am sure was my fault but the concept of a locking wheel appeals,

I saw two videos where no steering linkages were used....no chain,springs etc. Does this mean differential braking and rudder only for ground ops? Not liking that idea,but love the setup otherwise.
