Hall Bulldog Racer 1200mm


Hi All,
I've been quite busy lately and didn't get around building anything new, until now!
I saw this model in the Aerofred newsletter and I instantly fell in love with it.
I've started with the plans in Sketchup as usual, using a nice image of the 3-views as a reference.

Specs:
Wingspan: 1200mm
Wing area: 18 dm2
Weight: 1.2-1.5kg
Motor: Turnigy D3536 790Kv 715W
Prop: Wooden 13x6
(same power train as my Edge 540 V3 which is a powerful beast!)
Battery: 2200mAh 4S

Are you planning to hotwire the wings? If so, how would you build the shape?

Yes, Darren.
I'll hotwire them in sections and hold them together with a plywood spar.
Pretty much in the same way I did the Corsair.

figured that would be the way. So wing sections. Cut through at the longest point on the trailing edge. Nice work. What foam are you going to use? The yellow bunnings stuff?

Yes.
Started work today, cut the wing blocks and the inner top sections.
Note that I'm using aluminium flashing for the formers and ribs.
It works much better than cardboard allowing smoother cuts.
Thanks for the tip, Darren!

Amazing work. you should do a video showing how you work the hotwire on those tapered fuselage sections. This is coming together very nicely

Alright, got all the parts sanded over the last couple of days and I glued everything today. Hopefully the photos will give a clear indication on how the parts were glued together.

Great pics. Making more sense now. I can see how you glue the blocks to give the rough shape then hotwire the final using the template. Clever.
The masking tape is to stop the PU from expanding out and making a mess ??
Mate, you wife must be pretty cool to let you work on the dining table

Hahaha... yes she's got used now
I typically do this in my workbench in the garage but it's full of other stuff at the moment.
Yes the tape is for the polyurethane not to foam out.
