October 2018 Update: Back in 2015 you posted pictures of
the Ace Whizard I was building. I finally got around to flying it this year. It flies
fantastic and is so much fun, I got over 50 flights on it. Very maneuverable on rudder
and elevator, nice loops and barrel rolls, stall turns are fun. Glides well as every
landing is power off with the Cox Black Widow. I use the high compression head and the
gray 5x3 Cox prop. Flight time is about 3 minutes. Hand launches are hand off until it
gets altitude but it will also ROG on our grass field. - Steven
Canadian website visitor Steve S. is an
avid builder and flier of vintage model airplane designs that are powered by Cox .020
and .049 engines. He has in the past submitted building and finished photos of his
Simple Citabria, and Ace
Pacer models. As is evident by the many photos below and with his other models, the
level of craftsmanship is quite high and so they serve as great examples to anyone in
search of tips on how to properly build small R/C models.
Said Steve in his e-mail, "While not a feature in AAM, (although Ace ran lots of ads
for the kits from 1974 on) I recently scratch built an Ace Whizard from plans and using
the foam wings that Ace supplied with the kits*. They were rudder only but I added elevator
as well and power with a Cox Black Widow .049. It's ready to fly, the engine is running
well but I have to wait until spring now. I am always taken back at how overbuilt these
designs were as compared by today standards, but by selecting light wood they come out
at a decent weight. I guess that is why they lasted so long."
There is definitely a noticeable difference between the older model construction and
modern kits. Laser cutting of the wood parts has make incorporating lightening holes
and keyed joints more precise so that less material and adhesive is required for equivalent
or greater strength. The pre-built wood-frame models are amazingly well engineered using
almost all plywood that has been extensively lightened through use of material removal.
The structures look a lot like full-size home-builts. We've come a long way, baby, as
the old Virginia Slims ads
used to claim!
