I know that there are plans out there for Dale Root's Ascender. I contacted the company and they said for a fee, they would kit it for me.

A very poor picture I know, but this is Dale Root's Ascender. Babcock tone filter radio and K&B Torp 35.

Plan/article published in August 1957 issue of AAM.

That thing must really have a great power-to-weight ratio with an OS .55AX up front. At least I'm assuming it has the .55. Come to think of it, the way my Enya .45CX handles my 6.1 lb. Hail Razor, your AX, even if a .46, must really haul the mail with your model.

I've always wanted a Royal Coachman, by Sterling.

Well, Ed, you're welcome to a copy of the plans. PM me your email address and I'll send the file.

That's nice and light so you should have no problem with the II Perfection. Actually the point I was trying to make was to keep the wing light not so much the complete model. The increased inertia of a heavy, constant chord wing really messes up the rudder response - no ailerons on these things of course. The wing is huge ( 840 square inches) so the wing loading will be low even if you end up slightly heavy. Bill's original was 7llbs 4ozs with a Veco 61.

To try to promote the somewhat neglected Class II designs here is another - the Oily Bird.

Amazing, lil' Ugly Stik. I didn't know this fuselage and tail design was not unique.

I had a rudder-and-throttle model with a similar wing/tail layout but a not such simple fuselage. By the way, it flew slowly and - as a taildragger - did decent landings all by itself.

And by the way, why had some of these Class II models fully sheeted wings? A small D-tube would be torsion proof enough, I think.

Remember, back then it also had to be a little crash-proof.

Didn't remember that, thanks for the hint! I only remembered crash-proof was due to the wing (and tail) attachment with rubber bands because I tested this intensely back then. It worked most times except once when the model landed through a garden door.

Hi. Does anyone know if the RCM plans service is still around? I tried to order some plans and couldn't complete my order. Thanks, Jim

This was a great plane for my dad. It wound up in a flat spin and hit the deck. Thought it was a gonner.
We got to the plane and.... the landing gear came off and the prop broke...that was it.

Hi,

Old thread but anyway.
I got interested to see what Class II was in US so I did some search and found the various classes (I, II and III) and what they alllowed in each class.
Class I = rudder only, Class II = rudder+elevator, Class III = rudder+elevator+aileron.
No throttle control as far as I understand.

Here in Europe it was in the mid-end of 1950th (and probably beginning1960th)Category(Class) I = multi control, Category II = single channel (rudder only). It was also Category IVfor sail plane.

Below is two links to PDFs from "European championship" 1958 and 1959 for the above RC classes they competed in here in Europe at that time.
In the 1959 PDF file You can see list of what equipment like radio, engines etc they used.
In 1958 a guy from Sweden, Eric Berglund (picture below is him some years ago with the winning model still preserved), won Category II with his "RC Viking" (I have the plans and even a kit of the plane that was produced here in Sweden).RC Viking could easily be modified to have also elevator control so it would then be US Class II complient I suppose. The competition in 1958 was held in Darmstadt in Germany at US Airforce base there.8 nations was present including one competititor from US stationed at Nellingen in Germany, Captain Ollie Strickland who had a plane Breezy Senior (Miss Ellen, named after his daughter) powered by Thorp 19 and equipped with Babcock Magic Wand. He entered Class II single channel and placed 8th.
It is a picture of hím and his plane in PDF file 1958 page 4 picture 8.

I just thought it might be interesting to compare someplanes, equipment, classes etc they had here in Europe at about the sameperiod You in US had single and multi(2 ch) classes.

Bem,
Class I consisted of rudder and throttle, no nose wheel steering allowed. Class II was rudder, elevator, throttle and nose wheel steering connected to the rudder servo. Class III was aileron, elevator and rudder with nose wheel steering connected to the rudder servo. There was also a nose wheel brake actuated by a cable connected to the "down" movement of the elevator servo. Proto taxi to and from the "hanger" was part of the scoring system.
