My first turbine jet was a Kangaroo and 300' hard surface home field. @ 17lb dry and a AMT 180 I never once Kangarooed it. Then I moved on to a floater KC and I had my first kangaroo landing. Then used crow before BVM announcment and started greasing them in.
I did notice at stock c/g location that if your not nose high 3' from touchdown that theres not enough elevator authority to get it high, almost as if it were in ground effect per full scale.

Another interesting point is I put an AMT 400 on in place of the AMT280 I've flown with for 3 years and it shifted the c/g by 5/16" rearward of OEM spec. With this newer location I definately felt more elevator authourity at flare and easier to get nose high in final.
The AMT400 residual thrust seems as its allot less than the AMT 280, sure is noticably easier to land. I've had enough elevator authority now to touchdown nose so high I can drag rudders. looks strange with such a long nose moment.

Using an Eagletree telemetry, I am now routinely 40-35MPH at touchdown with the AMT400 versus 50-45MPH with the AMT 280.
