I am building a new plane for a friend. It is an ULTRA-RC Katana XL (Extra light). The ARF is very new, so new that I am working without instructions. Ultra-R/C did send me a data sheet and I will get the instructions this weekend. I took some photos of the contents as well.

This ARF is similar to the Giles 202, so apart from the CG measurement it is pretty close as far as a "build" goes.
WING SPAN 75" ENGINES CLASS 140-180 40cc Gas
WING AERA 950 sq. in. RTF. WEIGHT 9.5 - 11 lbs.
FUS. LENGTH TOTAL LENGTH 65"
CENTER OF GRAVITY 5.25 - 6" from Leading Edge
RUDDER AREA 110 sq. in. WING INCIDENCE 0°
STAB.AREA 125 sq. in. STAB. INCIDENCE 0°
ELEVATOR AREA 110 sq. in. RIGHT THRUST 2°
ROOT AIRFOIL DOWN THRUST 0°

Mounted the OS 1.60 using gravity to help line up the engine on the cowl. Used a shortened DuBro Iso-mount. Tapped the mount for 6-32 bolts. This puppy uses a 3.5" spinner.

Regards,

Eric.

Almost done...

A broom-handle through the wing-tube provides support during the marking and positioning.

The OS 1.60 fits inside the cowl. Needed some excavation to get the after-market muffler in as well

Regards,

Eric.

I like it, I like it alot! I've not yet gotten into large scale gas planes, would I be getting in over my head with a plane like this?

I don't see the Katana XL listed on the ULTRA-RC site. Do you have a URL where we can find this plane?

Looks interesting! When can we expect the XL to hit the shelves?

Does it use the same landing gear a s the Giles? Also, is the wing area of 950 squares correct?

I suppose every body else already knows, but how do you use gravity to help line up the engine ?
