An ambitious project - scratch-built Avro York

[Frank v B]

The sign of an experienced builder/flyer.  Lots of room around the wheel when retracted.
 
Retracts always bend, bind, jam, slam, refuse to retract or jam in the "up" position*. 

They generally refuse to do their job when too confined like modellers stuck in basements instead of at Rogo Field.

* see a qualified mechanic is this happens for more than 4 hours.   (Sorry)

Forward and top fuselage under construction.

It's sort of like a puzzle that I make up as I go along.

[Michael]

More work on the fuselage and the wing-top.

Looks amazing! 

[bweaver]

Looking great!

[Michael]

Wiring done. It seems there's about 18 miles of wiring in the wing!

Anyway, the motors all turn in the directions I want, and the retracts work.

Total weight so far is 1750 grams, or about a couple ounces less than 4 pounds. Hopefully, I can keep it under 5 pounds including covering and battery.

I'm on-and-off worried that the tail is a bit too small, but (there are 3 rudder/fins) it is almost the same area as my 60-size Mustang which weighs about twice as much, so I'm guessing/hoping it'll be okay.

Next: finish the nacelles, maybe make my own spinners, and make a battery hatch.

This really is an amazing project Michael.  Well done, Sir.

Michael,

re: "I'm on-and-off worried that the tail is a bit too small, but..."

I don't know if you are using model plans or scale 3 views.  One of the guidelines I was told in WW2 models is that tail feathers should be enlarged by at least 15% compared to true scale.

For what it is worth.

Due to compromises in construction, this will be a "semi-scale" rendition.

Covering and some detailing underway.

All three fins/rudders have been enlarged.

[Michael]

All major construction, covering, radio installation, power installation is done.

Total weight is 5 pounds with battery.
I still have to build a battery tray, adjust linkages and adjust throws.
I'll do additional decorations after a successful flight.
I may add an ounce or two of nose weight.

Now I'm waiting for a sub 10 km wind sunny and warm day to fly it!

[Frank v B]

It flew today.  It was not the best maiden weather (gusty, from the west, oscillating wind) but Michael achieved it.
The take-off was absolutely perfect and the flight looked like everything went well.  Bumpy landing because of the gusts.  Great flying Michael.

Thanks Frank for the encouragement and help.

Here's a great photo by Andy, taken after the maiden.

Congratulations Michael on a brilliant project climax.

That's a great picture!
