Plans for a "plank" style thermal soarer?
« on: June 14, 2007, 13:01:19 PM »
Looking for plans for a plank style thermal glider ie windfreak, windlord, raven.

Would pay for plan or copy.

Fancy something a little different! 
I know about the Max from Traplet, but to my eye it looks all wrong.

It's ok Dave (Jones, RIP), he didn't mean it!  :'(

Don't be deceived by the looks, the smaller version flies very well IMHO and might even benefit from a brushless motor and Lipo upgrade. I have not flown the larger one, but if it is anything like the original one it will be very good.
Comfortably numb......

I like the idea of flying planks too, much easier to build :-)

There must be a decent (free) plan for one somewhere?

Try these, the magazine is defunct but the plans are still available ( I have bought these plans since the Mag. went down the plug hole ) These are just from the Sailplane section.

here are some in my collection of "must build one weekend"  :''

This is the Six Foot Plank, the article is for a 76" slope soarer in Radio Modeller June 1995. Plans should be available from RM direct.



And here is the little brother, the Short Plank! 48" span, and was a free plan in RCME Volume 42 issue (?)



AIN'T IT CUTE?  :nananana:

Hi Bill

Years ago I had some fun with the Gooney Bird 100" plank..1000 sq in area IIRC...

A short fuselage with plug in wing panels with tip dihedral, separate elevator and huge rudder, it worked very well as a slope floater in light winds..

The plan showed an electric fus with a 5:1 geared 540 and 15x12 very flexible folding Robbe prop, but I remember I used an Astro 25G, 15x12 red Robbe folder, and sixteen Sanyo 500mAh reds. Several steep climbs to height usually gave me 20-25 minutes a charge and I had tremendous fun...An amazing soaring performance given that it was a plank..Can't remember the designer's name...Gerry, Gerald, ...? but he played a blinder with the Gooney Bird...

H.mmm...Think I may still have the plan somewhere...should go well with this new fangled stuff... ;)


Try...

Plan No R1376 Gooney Bird 14.50
Give me the job and I'll finish the tools..

Thanks acrofly.

If you're looking for an electric plank try the sushi 400 from traplet. Reatively small, but goes OK on a standard 400. not a bad glide either. Originally I flew mine on 7 x 500AR. Went OK on this but was a little heavy. Flown a couple of times on a 3s1p 1000mAh lipo. Brilliant performance, but I don't think the motor will last long!

Yes I had one of these, but not enough sparkle about its performance so scrapped it. I also had a Twister from Robotbirds ( everyone else called them Twist, originally from Velkom but now from Freeair I believe. ) I had two, nice zippy performance but wrecked two of them on landing, they would insist on bouncing back into the air ( due I think to the curve of its belly and undulations on the ground ) stalling and doing a death cart wheel.
            I now fly Frankenmodellbau Mamba 3000 wings ( 2 m. span ) I have a short and long nosed version, a third is on order ( with wing spoilers ) they can be fast or gentle, have not as yet thermalled with them . I still have to test fly my Let Models Taborca ( 3.3 m. span ) .
          In short I like "Flying Wings "  :)

Does anybody have the Wight Wing plan available? I'm after it since a while but can't get it anywhere!!

Try asking this lot as they took over a stack of plans from two magazines I believe,
