With flying colours, Ray, as always, had the RCM article in question - thanks.

If anyone else had the MAN article...?

A little further update - we have a fuse top!

Now that I have the basics in place, I have to assess whether something is missing and/or where I need to make changes. Otherwise it is down to the fine tuning and dimensioning verification. That done, I can start to prepare a parts plan sheet followed by a laser cut file.

Not counting the hours pouring thoughts over it, I'm pleased with how quickly the plan actually came together. Having foam core surfaces definitely expedites things as there are no innards to lay out and draw.

I'll leave the rear mounted servo for the elevator in there for posterity (and the TOC plan which actually may require it if using 8s) but I can almost certainly see it mounted in the radio bay with a CF pushrod.

Rummaging through my mystery LHS I found an MK elevator control horns which is essentially a U-wire joiner with a bracket welded on for actuation in the center - simple. This will allow a single CF pushrod to be run down the center of the fuse to actuate the elevator without any exposed linkages. The only linkage visible in the rear will be the P-P wires for the rudder.

The aileron servos will go in 3/32" recessed balsa pockets in between lightening holes in the wing core. Ball links at the servo end, CF rod and clevises at the ailerons.

Any suggestions on what should be included or changed on the plan are welcome. All the annotation of course remains to be done.

TOC Cap 21

Special "Dox-Dalotel E/G 30" wing/stab sets will be available from Rusty's elf named "Foamy"!! Thanks to the fine work of Doxillia, we have another cool airplane to distract us. Dox will receive a free set of foam wing/stab courtesy of the Classic Pattern-Trader as an "atta-boy".

Dox-Dalotel E/G 30- 3/4 pound wing and stab set $60 plus shipping and minimal box charge ($10)

Available for shipment by NOW...send a RCU (PM)/call me for more information.

A fellow modeller just finished his electrified Byron CAP 21 with an 80" span and a 10s5000 AUW of just under 15 lbs. I thought I'd post a photo of it here as it will hopefully inspire me to get back to the drawing board and finish up the plans for the 50" and 75" "e-light" versions here.

Jasons 80" is powered by an E-Flite 160 and 10 40C cells spinning a 20x8 prop at 7200 rpm - this is in the 50cc gas equivalent ballpark. My 75" version is targeted to come in at under 10 lbs and use 120 equivalent E-power with 8s and something more along the lines of an 18" prop.

Here's a link to a spinup test of the beast:

I hope May will bring me back to the drafting table as I'm getting close to finishing the frame up of my winter builds.

David.

P.S. Rusty, I also hope to finish up the Dalo 30 110% plans so we can start thinking about building these birds. They'll hopefully make for a good fall project.

Well,

it has been almost 8 months since I updated this thread but there has been some progress since. I may just be working on a few too many development projects at the same time - but so it goes. I have been in touch with a foam core supplier (to be discussed later) who will be producing cores for both the 30 and 90 TOC size models for both the Dalotel and the CAP 21. Hopefullt the 30 size cores will be produced early in the new year allowing me to build wings and stabs while the laser wood fuse kits are being cut.

In the meantime, I may have just parted with a limb on the purchase of a rather interesting little engine - a Japanese G-Mark .30 cu in twin boxer (dual .15's). I have always been a fan of boxer engines (including the one in my old Subaru) and while my concept for both the Dalo and the CAP is for them to be e-powered, I decided to reserve the possibility of a glow installation. This one would most likely go in the CAP if I decide to go that route.

These engines have a reputation of not being very strong but of being reliable and smooth running (they are Japanese after all). A suitable prop would be a Graupner 9x5 or 9x6. Since the models are light in concept, this little jewel might just do them justice even though it might not be equivalent to an OS 32 SX or 35 AX for example.

If anyone has any further information or experience with this engine, I'd be very interested in hearing about it.

David.

Image software working now. Here are the pics of the engine.

The Twin-15 30 G-Mark finally arrived.

Beautiful little vintage engine. Checked it all out, put some plugs in it (actually some 30 year old NIP Fox plugs!), a prop and spinner and oiled it. It is actually in mint shape (well, it has never been run). I'll need to run it this spring to check real compression. At the moment, it is a little "soft" but I believe there are 3 head shims in there, one or two of which can be removed depending on fuel and plugs.

I understand it may only put out about 0.7 hp compared to a whopping 1.2 of an OS 32 SX or 1.0 of the older OS 32F, but you can't beat the "scale" twin cylinder realism!

As I was looking at it, it actually made me think of Hanno's geared dual Webra 90 rig on his TOC Dalotel...

BTW, in these photos, it is over propped with a 9x6.5. It runs best on a 9x5 (which I don't have).

Hi, I'm Paul, flying models in Belgium, Europe. I found this older topic by a google search about my own Cap 21.
I think I actually own a Cap 21 which once belonged to hr. Hoppe. The model was rebuild with a G-62 and a Tony Clark exhaust and hydromount. You can find pictures in this thread; http://www.rc-network.de/forum/showt...503-TOC-Cap-21

David, I just came across your post about the CAP-21. It just so happens I owned one of the only (Real) CAP-21's in the United States and flew it in contests as well as airshows for many years. It was Ser.# 10 and when I bought it it only had .2 hours test time on it before being shipped to the states. The whole airplane was made of wood including the landing gear legs! The only real difference between the 21 and the 20L/LS (which I flew as well) was the wing. It was call the Ice Cream Cone airfoil as if looked at from the side tipped up on the trailing edge it was shaped like an Ice Cream cone. The main fuel tank only held 40 Liters of fuel (Approx. 10 gals) total! it was plumbed for tip tanks and also had an Aux tank that fit into to headrest area. Going X/C was a challenge to say the least. If you want you can watch the last flight I ever had in the plane on YouTube, I think you will like it..

Nice recovery, Kirk.
Chris...

Gentlemen,

thanks for reviving this old thread. Great posts!

I'll reply properly as soon as I'm in front of a keyboard.

David

Thanks Chris, you just never know when you're going to have to do some of that " Pilot S*#T " and become a glider pilot.

Blue Skies

Here is a picture of my CAP-21 I flew in competition and Airshows, it was a fun plane and no bad habits at all.
