Custom Cavalier 108 (oz335)
About this Plan
Berkeley Custom Cavalier. Wingspan 108 in, 1943 gas RC. Could be built with either single rudder or twin rudders.
Quote: "The Custom Cavalier '108' is the latest design in the famous Cavalier series. It is the proven result of eight years of inprovement on a basic design. This custom-Cavalier 108 was designed primarily for experimental work in remote controlled aircraft. Control surfaces and recommended control mechanisms are shown. However these are optional and should not be used when model is used in free flight.
The model can be easily built by anyone who has had some model building experience and who is able to follow the plans and instructions. The model and plans are not intended for the beginner or the modeller who is interested in putting something together quickly. It is a model that requires a considerable number of hours for construction and when finished will bear evidence of real craftsmanship..."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

I have an original one built in the '40s. Has a single modified fin and rudder. Want to make a single original design fin and rudder. Anyone have any thoughts?EmilCost - 13/06/2016
Mary, I am finishing the restoration of the Cavalier. It will soon be taken to our RC flying field for taxiing tests. The plane is a rare one. At that time, pictures will be taken. You will receive images of what happens. I would like to read what the plans said about the building and flying. Do you have the building and flying text?

Can anyone help Emil with the instructions for this plan?
Mary - 27/09/2016
I have an original kit, with plans, that is from the '40s. It is unbuilt and as far as I can determine, complete. The plans are 3 or 4 large sheets. They are quite fragile from age. I will be willing to help.

Thank you Dave, that would be great. Are you able to scan the relevant parts of the plan and email them to us?
Mary - 02/11/2016
Mary, Sorry it took so long. I think this will provide the needed information [see supplementary file]. Additional info: 1943 Cavalier 108 Custom Berkeley Models; Shows twin tail details (no mention of single tail); Supplement sheet shows twin engine option; Flying notes add warning about flying near coastline (wartime 1943).

Mary, I have finished restoring the original 1943 Berkeley Custom Cavalier. It now has the original twin rudders and stabilizer constructed from your Outerzone plans. The plane has been outfitted with the latest radio and brushless motor technology. I am 90 years old and have loved the hobby since I was about 8 years old when I got my first whiff of model airplane glue. (Just kidding about the glue.)

The Custom Cavalier is a very rare model airplane because so few of them were built and received so little attention simply because of its size, 9 foot wingspan and possibly the fore runner of the twin tail shape that is so evident when three famous real airplanes display the same shape. They are: the Lockheed Super Constellation; the Lockheed P 38; the Aircoupe. Can anyone add to that?
EmilCost - 28/11/2016
I can add a few, e.g. most modern fighters and then the Vought V-173, the Libellula experimental, Martin XB-51, HL-10 triple fin (NASA Lifting body), Proteus by Composite Aircraft, to mention a few odd aircraft. There are more to be found like the B24 Liberator. Please enjoy these wonderful (contraptions) aircraft.

Hi Mary and Steve. Custom Cavalier 108 (ID:335) built in the "Escuela Central de Aeromodelismo", Madrid, 1947 [more pics 003-005]. OK Twin engine and homemade radio. This was one of the first RC models built in Spain. These photos were published in the Spanish magazine "AVION" (1947). The quality is not very good, but it is the best thing that I've been able to get :) Saludos from Spain.

Have completed twin rudder configuration. Have ground test performance video. Have successfully flown it. Video documentation. Your viewers will like to see it. My date information: Built 1943 from Berkeley kit. In storage until 2016. New tail section and electric package installed. Maiden flight October 14, 2018 (3 weeks ago). Now in storage until 2019.

Notes
* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
Scaling
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
