Very nice Bill!

Looking forward to this one too.

Lools like to big a prop for a 480. Did you super size the motor?

Real Nice Bill! Looks just like mine minus the Pumpkin Pilot and spinner! I notice you used some small screws to attach the canopy. Probably a good idea as I found it quite an exercise to glue on!

[retiredVTT]

Yes...you only mess up ONE canopy with glue before you decide to screw them on....besides, the little guy is allowed OUT once in a while...!

Dave..prop is a 11/4.7 SF from APC. This plane is supposed to 3D and prop hang, etc, so needs a large diameter prop.
This Torque motor is rated 277 Watts on 3S...about 25 amps. Compares nicely with the EFlite 480 motor.
"Pumpkin Head" was found living at Dollarama...so I adopted him for $1.50 + tax and promptly threw away his body...he didn't need that..!

So on the maiden flight, I land short of the field by two feet and not only break a prop...but tear out the landing gear plate by landing in tall grass. I could hardly believe that this gear plate was this fragile with it's simple butt joint with the balsa sides of the model.

Here is my repair description.

A pair of spruce (or basswood) longerons were added to each side...I label them "A" and "B"...these are epoxied.
A 1/8" 5ply gear plate , labeled "C", is positioned above A and B and secured. Any landing forces are now distributed via A and B to the entire front sides of the model.
A new bottom, from 1/16" ply is epoxied into place and clamped overnight.

The new bottom is sanded and edges tapered...and new covering is applied.

Although I show steel cap screws holding the landing gear....I likely will change this to 4/40 Nylon bolts in future.
