Peter Rake IPS Farman Sport monoplane

O.K. - here we go with another of Pete's IPS series designs. This one's a Farman Sport monoplane, the original of which was intended to compete in the 1926 Coupe Zenith. Pete did a Speed 400 design for this plane a few years ago, and there is a build thread of it here

This version is 24" wingspan x 9.5" chord which gives a 228 sq.in. area. If I can hold the weight to 7 oz., that will give me about 4.42 oz./sq.ft. loading.

So far, I plan on using the following electronic kit for the build:

GWS IPS with "A" gearing
7 x 6 GWS prop
2 x Bluebird 303 servos
450 mAh 3 cell LiPo battery pack
GWS Li480 ESC
GWS Naro receiver

The ESC (15A!) & battery pack are definitely overkill, but are all I have available at present. Battery pack weighs 36gr, so it shouldn't be too bad - only 10gr heavier than the 300 mAh packs I usually use.

I did the wing first, as there's a lot of it (comparatively speaking). So far, so good. Now on to the fuselage .....

Interesting plane.

Looks to be the original flying barn door.

I'll bet you could lose a 10th of an ounce if you removed 2/3rd's of the ribs!

That wing weighs 43 grams (1.5 oz.), motor, servos, battery, receiver & ESC account for another 90 gr (3 oz near enough). Hmmm - only 2.5 oz left of the weight budget if I'm going to stay under 7 oz. Fortunately those are the major weight items in the plane, so hopefully it will all work out in the end.

You will find the undercarriage and struts make up most of the rest.. the actual woodwork will be sub an oz I would say.

Don't worry about going up to 8oz. It will still fly well on 3s LIPO.

I might give one of those a try when I make the aileron version, Loooeee. They aren't available here as yet - where'd you get yours?

It's been a week or so since I updated this log. I plead pressure of work, getting to grips with a new camera, and being distracted by building an R/C Pistachio version of the Farman for next Monday's indoor group meeting.

However, all is not lost. Wings, tail group & basic fuselage are done, as are the wheels. Next up is R/C gear installation, dummy motor & nose construction.

There's been lots happening these past few days, but not much to show for it, as most of the effort has gone into planning gear placement, cable runs, varying battery locations, etc.
I tried making a paper template to simplify cutting the cockpit & nose sheeting to shape, but it didn't work out properly. As you can see from the pics I wound up making 2 seperate sections instead of 1.

"Woodbutcher" , huh?!
I like to think of myself as a reasonably tidy builder, but that's wonderfully precise work, much nice than I can do. It always shows in the small-scale jobs. If I did a Speed 400 version twice the size, the build photos might look about as good as your IPS version.

Yep! That's what my old woodwork teacher called me, anyway. He also gave me the single most useful homily I've ever heard - "If you make a F@#k-up - make a feature out of it ...

But it's mostly Pete's design which makes for a good fit. All I do is cut the bits out as per plan.

Well I really don't have one, yet. I'm pretty sure that United Hobbies carries a clone or a rebadged one under their own Hextronic line of small outrunners. At least it looks the same as the Elec motor, and they get some rave reviews by rewinders and other modders of small motors.

Greg,
Would one of these be any use? http://robotbirds.com/catalog/produc...roducts_id=158
I had been planning to use it in my Hergt Monoplane but the bulk of the fuselage makes me suspect that the baby AXI might be better. If it looks useful, you're welcome to it.

Pete,

Looks interesting, and certainly worth a try. Yes, please! Email me with cost & I'll send the funds over.
