"Ganagobie" Peanut scale

[staubkorb]

After seeing Georg Törnqvist's Ganagobie up close and flying at the IIFI (took first in Kit scale!), I bought one of the Peck-Polymers kits from the Nijmeegse Luchtvaartclub grab box at the meet (they must have had a mass build project for this model at one time, as there were a number of them to be had).

The "Ganagobie" is a cute French homebuilt that I had often considered, but I had not good access to the kit. Problem solved!

The wood is quite good, but the strip density varies quite a bit, making choice for longerons a tad difficult. I've gotten the stab built (two sizes are shown on the plan - scale and oversize) in the scale size and if I have enough strip left over, I'll build the larger one - just in case. I have to check out Georg's build to see if he flew the small stab. I have to change my outlook on "competition" - just a little...

Oh yeah, the wood... all sheet stock is 0.7mm - less than 1/32nd" for formers and ribs - and the strip stock is mostly 1.5mm and 1 x 1.2mm (tail group) falling in the 5-6 pound density class. Not so easy to work with!

Photos to follow!

Cute airplane that fly okay in Peanut size.
I built a Peck one from a kit I won back in the '70s.

looking forward to some pictures, Pete...

BTW, I found your hat...

I figured it got stuck in your car after I searched for it the other day... It's usually the first thing to go on my head before I open a door (tired, I guess...).

A few photos of what I have accomplished during the virtual "reality" junk on the tube (Am. Football is reserved for watching ).

Having to build the "formers" is a new twist for me, and the 1/20th (1.2mm) sticks plus the 0.0276" (0.7mm) former gussets make everything very interesting...

I think I've built 3 to date! Great fliers...

Good luck,

Dan.

Fiddly little bugger, tho!

Hi Pete, for some reason or another I have built two Ganagobies
Liked its looks, don't know why...

First one with the bigger stab, second one with the scale size. Had lots of trouble in getting the second one flying, can't probably blame it directly on the stab size though.

It all depends what you are building it for. If for kit Scale, why not build it with the bigger one? It shows in the plan as the primary size, just do the Ganagobie as the plan says. After all, that's what the kit scale is all about!
I'd probably build one with the bigger one even for peanut, if I ever do a third one. F4D is of course a different thing, but for that one I'd scale it up to around 50-60 cm span for somewhat easier trimming.

I really can't say why I built the small stab... it LOOKS to be in the zone, but measured, it's only 16%. I'll go ahead and build the big stab... As far as whether it'll be for competition or not will depend on how it turns out and whether I can get it to fly satisfactorily.

I gotten the fuselage nearly done - construction-wise. Only needs the nose sheeting and the landing gear gubbins (bend the wire and add the locating braces. Starting to cut out the ribs. Todays photos show the fuselage as of 7AM minus the bottom keel and the cabin braces/framing - weighs 0.680 gms. The weight crept up to 0.888 grams with all the work from today and will probably hit 1 gram once it's ready to cover

My RIVETS fuselage was a snap compared to this beastie!

The fuselage now. Wing ribs are cut out and trued.
