You might score higher with operational flaps Jim.. Panel-lines for the flaps may have been sufficient.. but since you've cut the flaps out.. there's the possibility of them buffeting in flight now.(??) I guess it depends on how rigid they are. That Norvel should haul the mail on this model. It would suck to end up with a turbulent trailing edge on your wing.

The way I see it.. you're fabricating this unique model completely from scratch.. and it's of the build-quality we've all come to expect from you. Why not kick it up a notch? Smile

Got 'er covered with 3 coats of clear, carbon veil tomorrow hopefully. Landing gear is done.





Tried some test graphics from Calie Graphics on my stringer test patch, came out great!


The contest is a month from tomorrow, I need to get this thing done. I don't want my official flight to be the test flight like last year lol!

Looking good Jim , what happen about the stringers ? did you decide not to use them / I know you went to some effort to get the pieces for it . As Ron said the landing gear did come out sweet . It is looking more in proportion now . Eric

Thanks guys! The landing gear came out more complicated and heavy than planned but I can always change it.

Eric, I'm going to add the stringers after the carbon veil. I think I can get a cleaner look that way.

Looking great Jim! Can you give us a close-up shot of the landing-gear? I love wire-gear.. and have used it exclusively on "all" of my models. I'm always looking for more ways to build wire-gear. Yours may seem heavy now.. but I'm sure that you've figured it into the overall balance of the model. I've attempted to build "more" suspension into my wire-gear by soldering a tension-spring between the struts. I've even "tied" the front struts together with a spreader-wire; linked/soldered to a tail-strut-wire. If using small diameter wire-struts, it can help to support/spread-out the weight of the gear.. as opposed to using a rigid/heavier-wire V-gear that's unsupported.

Many modeler's (as well as kit-manufacturers..) don't think about the stresses that landing imposes upon a model having landing-gear. It's likely the most shock that a model will incur in it's life.. other than a crash. You can't always count on a "greased-landing".. Laughing  A hard-bounce is best absorbed by a gear that flexes and rebounds, as opposed to bending.. or transferring the shock to the airframe.

Is the gear in your R-1 in the scale-location?

Roddie,

Yes the gear is in the scale location. It will probably have zero flex but remember this plane might get test flown once or twice and then flown maybe twice a year after that. Here's some photos of how the whole thing goes together.

Thanks for posting those undercarriage pictures. It is much clearer for me now - from just the side view it looked over complicated - now it looks ingenious!

Carbon veil on with 3 coats of dope. Sand down and apply 2 coats of sanding sealer tomorrow, stringers on Thursday or Friday. I may have paint on this by the end of next week.

Nice ball-peen there on the table.. Hope you don't use that for resetting the Cox's ball-socket/rod-piston joint! Laughing

I used a small drill in spin vise to simulate cowling fasteners.
