Have finished the wing and am starting on the canard.
The only problems I'm having so far is trying to understand the assembly instructions.
They are way more complicated than I am.;-)
I plan to add an electric motor and folding prop, I welcome any advice on what is best combo for this plane.

Have finished wing, canard, rudder and fuse.
Preparing to assemble.
Will post up pictures a little later.

Looking forward to the build updates and photos.

I've made quite a few changes to the original airframe to accommodate the electric conversion.
The wing is sheeted top and bottom as well as the canard.
The fuse is made with 3/32 balsa instead of 1/16 and there are three 3/32 plywood hatches on the upper surface in order to access the motor, ESC, battery and rudder servo.
I'm using a NTM Propdrive 28/36 1000kv 400w motor, a red brick 70A ESC and a four cell 1600mah lipo spinning a 11x6 folding prop.
Should be more than enough power to get it up and out of sight.
I still have lots of sanding and shaping to do to the nose of the airplane but the hard stuff is done with the exception of covering it.
I will use Ultracoat but haven't picked a color yet.
Comments and advice sincerely appreciated.

Well, bummer.
Back to the drawing board.
With motor, ESC, & LIPO battery as far back as it could go, it needed 27 ounces of ballast in the back of the airplane to balance it.
I'm pretty sure it wouldn't have been a much of a glider with that much ballast.
I'm toying with the idea of building a pod that bolts on with the wing bolts that puts the motor, ESC & battery right at the CG point.
Are there any huge difficulties with having the prop wash within inches of the rudder, other than making it very important that rudder trim is correct prior to the first powered flight?
I plan to toss it off of a hill unpowered to get all the trims ball parked before I try firing off the motor for a hand launch.

I've mocked up a motor pod, what do you guys think?
The CG is marked on the piece of blue tape on the fuselage (2.5 inches in from the main wing).

Canarrow 2.01.


Motor/ESC has been moved from the front of the plane to a 2" ABS plastic "Pod" above the CG.
No additional ballast needed for proper CG. *whew*

299 views and I can hear the crickets loud and clear.

I have an unstarted kit, I'll get to it someday. Have you flown it yet?
