Hi all,

A while back VMC decided to ask me to design a simple fun flyer that could be built in less than 4 hours,  be buildable by a novice and that would be ok indoors and outdoors on a calm day.

For some time we called it “Project X” as we didn’t know what to call it, but I the end we decided on “Pilot” as the idea is that it be the first model that someone might build, that hopefully would lead to more...

There are twin fins mounted on the ends of the tailplane, this isn’t entirely for aesthetics, as they both stifften, keep straight/flat and lend strength to each other.

The all sheet fuselage can be covered top and bottom by the coloured panels provided on lightweight paper or tissue covered as desired.

All of the sheet is 1/16”, however you can reduce this down to 1/22” or less on the fuselage rear and tail group and it still pretty robust.

The span is 19” with a 6” prop as standard.

The plan isn’t a traditional one, it is generally shown like Ikea instructions, just with the traditional layout for the wings.

The model as shown in the pictures complete with 3/16” rubber sans noseweight is less than 25g stock, and I estimate that it will require 1-2g to balance.  Sanded rear surfaces and tissue in lieu of the paper will mean very little required nose weight.  Fitting a 7” prop might require tail weight!

Some pictures..

Andrew

It certainly has appeal Andrew. That's not a Bird Dog wing by any chance Smiley?

Perfect subject for the fellow in Belgium who built the SE5a.

Hi Guys,

Yes John you’ve rumbled me!  I was sketching things out when I looked up at my shelves and saw my rough hand cut Bird Dog prototype.  Five minutes later I had hacked the centre section out and glued the two outer panels together.  I liked the look of it and decided that was that!  Sort of felt a bit like that film “Flight of the Phoenix” - less of the searing heat, hard labour and lack of water etc of course!  Grin

Performance is reasonable for a model of this type.  The accent was more on a decent aesthetic and ease of build.

I don’t think it will be long, they already have the prototype for pictures and the plan and instructions are nearly complete...  I think that they want to do a video of construction which a guy does for them.

Cheers

Andrew

A quick video of some early flights on a less than ideal day with a rough cut prototype in some pretty heavy wood (with wing as per hacked one - complete with a horrible warp!)

Very reminiscent of the old KK "Gemini"! Good one...

Funny flight pattern! reminiscent of the way my Fokker DVII's fly! A stalling turn! How the "H" do you fix it?

Easy, fly it on a calm day!  It was quite windy especially for such a small model.

Indoors and when it’s calm it behaves pretty well...

I think you may have achieved your aim there Andrew. Lots of flying potential there for a easy built beginners model.

I thought the model flew pretty well given the windy conditions!  Exactly the sort of good manners a beginner's model will need!  Grin

I notice that the Pilot flies to the right, whereas your Bird dog flies to the left. They are both HWM so why?
I know the Bird Dog was trimmed for indoor and the Pilot is outdoor and that is what everybody does, but why?

Hi Ron,

Don’t read too much into it.  It’s wasn’t intentional.  As I mentioned the wings were rough cut prototypes of the Bird dog ones, reglued without the centre section, and bodged with a filler piece to make up for the gap due to the increase in dihedral between the two.  I covered them really quickly as I wasn’t too worried about how they would look). In this haste I got a warp and one wing at a differennt incidence than the other...  The result of which was a tendancy to turn right, and so I just let it!

I have a few indoor models that like to fly right too...

VMC launched this kit a few weeks back, it took them a while due to issues with getting the pre bent undercart manufactured.

One chap was obviously quick off the mark to build one as I came across this video.

Not bad for a beginner's model Andrew. Hope it does well.
