Thanks for the idea Pit.  I will try that setup this weekend and let you know how things go.  Your right about the dihedral.  I meant to build in more but Goofed it up.  BTW, what is the rule of thumb (if there is one) for the proper motor weight for a given model.

Hi everyone

I am currently building the bluebottle squadron fW190D for rubber power.

The fuselage is coming along and i think i have picked a colour scheme as per the photo

Does anyone know what the AUW of this model is supposed to be ??

Thanks

Pat

My current attempt at keeping my hands under control is a neat Canard twin motor design by the Master, Bill Brown.  It is the RUTANGO @ 75% scale (= 17 inch span/length) which has proven to be a bit of a challenge!  Don Mclellan built one with a 13" span, and has had no real luck getting it to fly (yet Wink).  After studying the plan - which is one of a couple that Bill did not get a chance to complete, and is unknown whether or not an alpha build was done - plus some experiments I've done with canard configurations, I've come to the conclusion that the incidence in the MAIN wing is the culprit for its recalcitrance.

I've built the model to the plan but, along with my mod to the fins/rudders, will set up the main wing with only the effective incidence - that is, the airfoil bottom parallel to the datum - and leave enough room to be able to change angle a bit.  A problem will be with the motor tubes, as they have a small x-section that won't allow too great a change in thrust angle.

Time will tell...

Hmmm... that is good to see Pit, as I remember you saying a while ago that time was a bit against you on the building front.  Clearly there is a bit of talent there for it so press on!

Thanks guys!  There are a number of things that are conspiring to hamper my building (and flying) efforts at the moment, but pressing on nonetheless Wink.  Does anyone know whether Bill got around to actually building and flying the RUTANGO?

The AUW is probably not in the plans or building instructions. One way to come up with a reasonable number is to compute the square inches of wing area. Divide by 2; that should give you the weight in grams to set as a weight goal.

Back in July while on vacation, the wife and I stopped at an ice cream parlor in a small town. Someone had an HO scale railroad diorama set up in the middle of the place. There were a few kids peering at the trains. I was talking to the guy and he wanted an HO scale plane to sit at an airstrip beside his trains. Someone had given him a very large plastic Jet kit. He passed it on to me to give to my disabled nephew and I promised to build and send him a scale HO model plane. I went for the PA-12 Supercruiser. I just finished it and mailed it off to him. Although not really a flying model, with only a 4 7/8" wingspan, it is the smallest model I have put together (so far). Mostly constructed of 1/32 sticks & sheet. Skins were printed on pre-shrunk tissue. Finishing was a single coat of dope. The tail wires were some red thread that I coated with dope to stiffen before cutting to size & gluing on. Finished weight was 1.2 grams. I would put it somewhere else on the site, but I didn't want to start an new thread for it. Here are some pics.

I actually finished this last spring but since it’s my latest creation, I guess it fits this thread. It’s a 24” Morane Saulnier Type N that I built using the excellent plans of fellow forum member Tony Ross.

I did an article on the build for my local club newsletter which can be read here:

http://www.lisf.org/home/wwf_free_flight/data/Building_a_Morane_Saulnier_Type_N.pdf

Here are a set of photos of the build:

I agree with Dave -that’s a great effort Steve. It’s a credit to Tony's plans as well. The very effective wood finish on the Peck (?) propeller caught my eye as well as all that rigging.
i was curious as to why you didn't add the wing mount aluminium tubing while the wing was in one piece, and then separate with the wing panels, as it almost guarantees alignment of the tubes.

Thanks for the kind comments guys.

It was actually easier to add the alum tubing after separating the wings due to the highly undercambered design. I just happened to build the wing in one piece as that’s how it was laid out on the plan. Tony’s design was for the LE and spar to be used for wing mounting. As this would be fine for a wing as originally designed, I knew with a larger 24” WS, 1/16” spars would spell disaster if I cartwheeled it. The tubes are directly in line with the LE and spar so alignment is no problem. Dihedral is easily adjusted by slipping a tight fitting brass tube over the mounting wires in the fuselage and bending up or down.  My Henry Struck designed 1911 Cessna uses the same system and it’s strong and makes wing adjustment and removal easy. I sincerely hope Tony fully finishes this plan someday and uploads it to the plan gallery. Better yet, someone needs to market his design as a kit. Laser cut parts of course!

I built one of these years ago when the plans came out in Aeromodeler.  Really nice design and it flew very well also.
