About this Plan

Talon. Radio control sailplane. Wingspan 50 in, area 310 sq in.

Discontinued kit from Bob Martin. Note this design was also kitted as the Dynaflite Talon (also discontinued) see supplement plan file. The 2 plans are essentially identical apart from the title block and credits.

Note the Talon was originally designed by Kevin J McDonald and Bruce Lewis. Some later versions of the plan credit Bob Martin as the designer.

Quote: "Hand-launch sailplane for thermal or slope flying. Flat wing with ailerons for ultimate maneuverability. Rugged, lightweight balsa/ply construction. Optional V-tail version.

Congratulations and thank you for purchasing the Dynaflite Talon. While the Talon is not necessarily an advanced glider, it is intended for modelers with some previous R/C building and flying experience. Due to its flat wing and relatively thin airfoil, the Talon is quite maneuverable and penetrates well, so it is at home either on the slopes or the breezy planes.

The unique fuselage construction yields an interesting triangular cross section that builds rapidly and is pleasing to look at. This instruction manual also shows you how to build both the conventional straight-tail version or the V-tail version. We hope you enjoy building and flying your Dynaflite Talon..."

Update 26/08/2018: added article from Spanish magazine RC Model, issue 1990/109. Also article on building tricks from Slope Soaring News, May 1989 (pgs 4-7). Both thanks to alcalaino.

Update 13/12/2022: Added ribs zipfile thanks to Paul Ayala.

Quote: "I picked up an unmolested kit of the Dynaflight Talon and recently scanned [as JPG] and converted the ribs to DXF and SVG file for another pilot. Attached are all three files. Cheers and Merry Christmas!"

LOL I was just looking for the plans for this glider the other night and lo and behold you read my mind. I had the earlier version of this plane that had a conventional tail assembly and after the first flight converted it to a V-tail to avoid damage. 6 months later they came out with a newer version of the Talon which now had a V-tail. I think I deserve some financial bonus from Bob Martin... "just kidding of course." This is a great fast flying glider, it is also pretty easy for a beginner, but it can be tricky to build. I lined the interior joints of the fuselage with fiberglass strips to give it a bit more strength. I found it helped immensely when I accidentally got too close to the base of the hill I was on and saw that the glider had cut off the tops of some cactus, yet it was still intact with only some minor cuts in the covering.

I was very happy to see one of Bob Martin's Talon plans appear on Outerzone just a few days before the maiden of my own Talon [model photo & more pics 006-010]. Even if I've built it from a Dynaflite kit, I hope my pictures will be of some interest to people wishing to build it from plans. Martin himself 'liked' some pictures of this model when I posted them on a Facebook Slope Addict group. It was a great pleasure, the designer himself 'liking' my build!

A Talon, Dynaflite kit bashed into a Super Talon (span bumped to 60", flaps added, original airfoil). Love this plane, flies on wires, with flapperons active rolls are fast and crisp [more pics 011, 012].

Bob Martin was the first to kit the Talon. It was derived from a design by Kevin McDonald and Bruce Lewis. After extensive redesign, Bob Martin RC Models kitted and promoted the Talon, a name that was originated by Bob Martin. It was kitted with the conventional tail with the option of a V-tail. This and other BMRCM kits were sold to Dynaflite but before BMRCM was paid for the designs, Great Planes bought Dynaflite and I lost out getting paid. I will be re-kitting the Talon, Pussycat and Bobcat as laser cut kits shortly - look for Kit Cutters LLC in Arizona.

A plane called the LR-50 was designed by Kevin McDonald and Bruce Lewis. They requested Bob Martin kit their plane. Bob Martin agreed IF he could make changes. That sailplane with changes became and was branded as the Talon, a copyrighted name of Bob Martin RC Models. Bob Martin currently retains the rights to the Talon.

I have owned two talons over many years and look forward to building another. However I am searching for sacle plans of the wing ribs

hello, could this work with rudder-elevator only? many thanks, eduard.
rautchi eduard - 18/03/2022
Only if you increase dihedral. This is an AILERON model (read the description). By my reckoning, you'd need about 3 to 4 degrees dihedral on each wing to be able to control it rudder-elevator only.
While you are at it, please round up the nose A LOT MORE. That muzzle is giving me the creeps! Can you imagine stabbing a bystander- or yourself - with THAT pointy nose??
OR you could simply choose a nice rudder-elevator glider from this august database. I suggest my old crate, 'Orange Box'. What a glider!
Arnaldo - 18/03/2022
The short answer is NO, it won't work with only rudder and elevator control. With essentially no dihedral, rudder won't turn it. Many (most) models designed for rudder only control have insufficient dihedral anyway. Yes they will turn but the action is very slow. How much dihedral do I need? A good rule of thumb is 15 degrees. That sounds like a lot but it's just barely enough. Resist the temptation to use less. I know it looks funny, do you want it to fly or look pretty hanging up? How do we measure the 15 degrees? Consider a flat wing to be zero degrees. Raise one wing 15 degrees and you got it. I just finished a Dollar Tree Foamboard version of my Guppy, using the 15 degree method, rudder only. It turns and flies perfectly, almost as if it had ailerons. It's fulfilling its mission to test new receivers of unknown goodness before installing in a good model.

many thanks for the explanations! it 's my bad, i forgot to add the next logical question "and what would it take to make it rudder-elevator?" :)
rautchi eduard - 18/03/2022
Hola, where can I get the plan of the super Talon? Thanks saludos
Manuel Contreras - 22/05/2022
Manuel, read the FAQ.
BillH - 22/05/2022
I built flew and loved this model many years ago, I still have it! I made one serious upgrade. I redesigned the fuselage to make it so I could plug the wings in using tubes and metal rods. Wire pockets in the inner ends of the ailerons.
Rubber bands with hooks to hold the wings in place. I am now considering using these plans to make printed planes! I may try to add a motor version, but space is an issue.

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.
