Kangaroo gear
Hello everyone, Im doing a retrofit on a kangaroo for a freind of mine. Originally it came with spring-air gear and he purchased the robart set with glennis wheels and brakes. I installed the mains with no problem, but I ran into a problem with the nose gear. For one, the robart strut is about 3 inches longer than the spring air. Consequently, if I were to attach a gear mount to the rear of the nose former, the retracted gear will hit the box that holds all the electronics. I was thinking of attaching to the front of the former and clearancing the bottom of th fomer for the air cylinder and strut when retracted. Also, this gear will make the roo sit at a high nose angle. Is this normal? Does anyone have a roo with robart gear? How did you mount it?
Thanks in advance

Roo Nose Gear
I have a Roo with the Robart retracts and Robostruts made for the Kangaroo.
It definitely sits "nose high". From the bottom of the fuse to the ground measures 7.875" (with a 2.625" Glennis nose wheel).
The Robart mains sit 6.5" from the fuse to the ground (with a 3" Glennis main wheels and brakes).
Here is a pic during construction that shows the geometry described above.
Hope that helps!

Kangaroo gear
Evan,
Leave the springair for the nose gear! I did the same switch about 16 months ago and have been using Robart mains and springair nose for hundreds of flights....Springair is plenty strong enough for the nose and mounts easier... Also, eliminating most of that positive angle of attack on the roo will help you avoid the hops down the runway on landings...Not needed for rotation!
