Andrew.

Scroll back to page 7 of this thread and you'll see a cowl for the Oodalally being built from balsa.........

GReat. So glad that you are happy with Oodalally. It is a nice model and yours looks great.

Andrew, I made the cowl in the same way as shown on page 7, 3/8" sheet for the top & sides, 1/2" sheet for the bottom. 3/4" triangle balsa is glued to the 4 corners inside. Think of it as a tapered box. Once you have glued the nose ring in place, plane and sand it to the profile on the plan. I hope this is of some help. Cheers, Richard.

Hi Peter,

As soon as I finish Harmony I will start building Oadalally. It is very nice simple plane ... just what I like best ... of course with the Great Looks. I have the Oodalally plans from RCME and am reviewing them. My question is the Landing Gear (U/C) on the Oodalally does not look like it would live long as drawn. The landing gear on the Harmony is some what similar but, is very strong. Am I just missing something?

Hi Leo.

Not sure why you feel that it won't last as drawn. I am using this method on all my designs at the moment. Not suffered a single failure except when I snapped tha saddles but that only takes a minute to replace.

I am now cutting a slot up the 1/4" ply side pieces just long enough for the leg uprights. THis saves trying to drill holes which sometimes break through the side. See the Swamp Rat build photos.

AS point of interest. I lost Oodalally dues to a snapped aileron conrtrol horn. I am now build another model baiscally the same but just cosmetic differences because I liked it so much.

No, It will be in another magazine.

Hi Peter,

What is to prevent the wheel from twisting on landig with just glue holding the wire in a slot withe just the pressure from a small pc of sheet medal held in place by wood screws? I remember some folks folding Ring Master Profile stunters in the very old days. The wheels ended up it the wins! I'm just wondering and the Engineer in me says Hmmmmm? I understand Harmony and it looks just fine but I don't understand what prevents the gear rotating in the slot in Oodalally. Got to run.

The undercarriage upright goes into the slot in the ply upright. The leg then goes across the fuselage underside before going down to the wheel.

The leg cannot pivot round the upright because it is held to the bottom by two nylon double saddles which hold both legs.

The leg cannot rotate backwards in the saddle because the upright prong in the ply upright keeps it vertical.

Consider it this way. The upright is held in the slot. Ther parts of the leg that go across the fuselage act like torsion bar suspension.

Let me put it this way. I use high quality 8 SWG piano wire. Some of my less delicate "arrivals" will bend that wire but the never make the undercarriage rotate in any way.

JUst a few of the models that I have used the method on. Harlequin, Swamp Rat, Oodalally. Melody.Study the build blogs on these models and see how it works.

Non RCM&E plans include Dancing Queen, Panic Attack, Alley Cat (not yet published) Witt Vee, Minnow, Wee Mad Arthur. Those are the ones that I can remember off the top of my head.

It works.

Peter,

I must have been having a Senior Moment ... of course it goes across just like the Harmony does and is strong as a Wild Horse! Forgive me me and thank you very much! Now to find some "real" piano wire!  Our little Hobby Shop is basically RC Vehicles.

WE all have them! Glad that is sorted.

8 SWG wire will be about 5/32". The stuff that I use is far better than the K&S wire.

Note that 8SWG is just about 4mm and its different to American 8AWG. Good piano wire is available from Balsa Cabin at major shows.
The U/C blocks for Peter's design can be made by cutting a slightly undersize slot in 4mm ply then covering with a 3mm plain ply piece. When the glue has dried ( and before installation preferably ) hold in a vice with a hard piece of scrap and run a 4mm drill through the slot. This just opens the slot to exact size.
I prefer to rake the slots and make the piano wire flat ( not raked and handed ) which is easier and both can be made the same. Very difficult to put the extra bend to rake the wire and make both sides the same but handed!

Peter, hasn't Alley Cat been used as a model name by Harry Gilkes some years ago in Radio Modeller or RCME?

Thanks Peter and KC for the "slot" method. I may use it when I build the Harmony fuse as well as Oodalally!

kc. I suppose the name could have been used elsewhere. I didn't know about it. I just browse music titles for a lot of names. As a point of interest, the basic styling was loosely based on a little rubber powered job. Once I had built the model I found that it looked quite like a Pete Holland design, Sky King I think. Nother new under the sun.

Yes, the slot method is much easier and works well. I use it all the time now.

I just had to see what Google might find and so look here: http://www.rcuniverse.com/forum/scratch-building-aircraft-design-3d-cad-174/10814649-plan-1216-rcm-plans.html

The website Luther refers to gives the full details of Harry Gilkes 'CAT' designs and I ( kdc is me ) stated that Alley Cat was a 1992 Radio Modeller design. So it should be in MyHobbyStores Plan Service somewhere.

Hi, I bought the plan and wood kit. I'm installing 3 Futaba servos side by side in the fus. There's not much room. Is it ok if the servo bodies actually touch each other?
