About this Plan
Delphine. Radio control glider model from Svenson. Wingspan 1200mm.
Dear Steve & Mary, Attached, a scan of the plan/brochure/building instructions of the SVENSON DEPHINE. With a wing span of 1.2m, it was my first 'big' model plane. Due to young age and lack of knowledge it never was a big success. We are now 40 years later, I am still building model planes and I make my living as an airline pilot. So, even though my DEPHINE was a mediocre flyer, it definitively made an everlasting impression? Many thanks again for a fantastic website! Peter

Update 7/12/2023: Added motor mount drawing, thanks to Peter Ingels.
Quote: "Dear Steve & Mary, In reply to a question of user HansL for oz8445: The attached plan is for version 1 of the motor mount for the Delphine. It was designed for an AEORC C20 2050kv motor mounted in pusher configuration. I made detailed drawings of the parts to have them laser cut, so these I can provide.
It worked fine but I wanted something more elegant and lighter. I therefore designed a version 2 for a racerstar BR1306 4000kv motor mounted in tractor configuration. I did not have access to a lasercutter at that time and made it in 'the traditional way'. So, for version 2 I did not make any drawings. It uses exactly the same principle and with a bit of handywork it can easily be recreated.
Many thanks for Outerzone!

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

User commentsI think this is an early version of the Delphine plan. The brochure (and the 1973-4 catalogue entry) say the Delphine plan includes power pod option for Cox engine, and also full single servo RC installation details. These do not appear on this (earlier?) plan. Maybe there is a copy of the later plan out there somewhere?

Hi Mary and Steve, I have the Delphine built in 28 days [more pics 003-006]. The Delphine is the first RC glider from Svenson. As I started, he was not yet on OUTER ZONE. In 1973 one could get there but 1 servo in. Now that's a full RC glider with altitude and rudder. Flight ready 250 grams., 200 grams less than in 1973. I have to test him, but the weather is too bad now.

Today's first flight with Delphine, fly excellent. A pleasure to fly. Photo: motor above wing [more pics 007].

Thank you to Peter for uploading the Delphine plan! The Delphine was my first attempt at an r/c glider many years ago. I had a new (at that time), Sanwa 2 chl set which I jammed in for rudder/elevator. Since the receiver, batt & servos were too big for the available space (not to mention my skills were lacking as well!), I laid the servos on their sides and had the complete output arms sticking outside the fuselage sides (!) with piano wire pushrods running down each side ..... not a very pretty arrangement but it worked. I couldn't fly at the time either, so the poor old Delphine had a rough and short life, poor thing! I have been looking for a copy of this plan for years so that I could build another one for old times sake, and perhaps this time it will have a happy and long flying life! Plus, this time all of the gear will be inside ... where it should be! Anyway, thank you again to Peter for uploading and thanks to you as well for keeping this fabulous site running for all of us to enjoy, great job!!

Attached, a couple of pictures of my brand new SVENSON Delphine [more pics 008-015]. Over 40 years ago, the Delphine was my first model plane. My current Delphine was built using the original plan. I drew most of the parts with a computer drawing program and had them lasercut. The canopy came from another model and was trimmed to fit the Delphine. The engine mount is removable, I also installed a towing hook. The fuselage used to be a bit too small for r/c equipment, but modern light electronics solved this problem. The Delphine is definitely not a high performance glider, but it still flies very well, with very honest flight characteristics.

Lovely models, and less than 250g as well. Just a question for Julien & Peter : What power setups did you use ? (Motor, prop, ESC & battery ??)
KvdB - 12/04/2022
Dear Steve & Mary, I discovered the request for info by user KvdB.The motor on the initial setup was a bit heavy and was installed in pusher configuration to keep the prop clear of the canopy. My current setup: Racerstar motor BR1306 4000kv - 5x3 prop - 2S 950Mah LIPO - Hobbywing FLYFUN 12AE ESC. This motor is lighter and uses a smaller prop. I could mount it in tractor configuration, this allowed me to move some weight forward and to remove some lead in the nose of the plane. I attached a picture [pic 16]. A very late reply, but I hope it is still of use ;) Many thanks for all your effort!
Peter Ingels - 22/11/2022
Much appreciated, Peter :) ...very valuable info indeed !!
KvdB - 16/06/2023
Dear Peter, do you have a drawing of the pylon motor mount you can share ?
HansL - 05/12/2023
Done, thanks to Peter - see supplement file for drawing, and update text for description.
SteveWMD - 07/12/2023
OK, thanks for the quick reply. The thrustline can be adapted. What thrust angle do you have with the propulsion setup mentioned above ?

* 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.
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.
