Paco Modell Taltos "Pegasus" 3.5m RES Kit Build

[Spookyeng]

Hello Guys,

I have one kit that I have wanted to build for a little bit and the only one I am going to keep for now. I just miss building and designing. I started a thread on RCG (27 Jan) and wanted to share with the group here, in case there is any interest here. Start of the thread below.

Well, I have decided it's time to put the Paco Modell Taltos "Pegasus" 3.5m on the bench. It has been sitting here for about four or five months and I have thought about selling it a couple times, but it's just too beautiful not to build and it was quite the ordeal to get it here. It sat in Memphis for almost two months and I was not sure I was ever going to get it with all these TSCA forms and other BS. Additionally, I want to document the build, so others, who might be interested, can get an idea, how it goes together and there is not any build thread that i can find.

It's a RES glider and based off a design by Borlai István in 1936.

You can find more information on the kits here: Paco Modell

I can't say enough good things about Gabor at Paco Modell, throughout the shipping, he helped as much as he could, provided forms, and is only an email away. I had some broken parts from the rough handling of customs, since they tore the box open and inspected every part. Gabor helped me with cut files, so I could laser cut what was broken, since I have the capability here in the shop. I have been so happy with Paco Modell, that I am eyeing up the Jaguar next in 3.2m

The kit is well designed and should go together fairly easy. I have sent an email on a couple of items to clarify, as there are a few plans and parts issues to get sorted out, mainly in my head. There are no instruction, just the plans you see pictured. Gabor includes a nice CD with some pictures (they are of the completed model), but there is no manual and that is the intent of the build thread, to create an online build manual. I am scratching my head a little, but as I look at the parts, plans, and pictures, I am gaining and understanding and appreciation. It is nice to have jigs for the fuselage and wings!

I bought the kit, with all the supplied motor, esc, spinner, prop and servos. i may use different servos, but not sure yet.

I don't want to type a dissertation as i can get a little long winded when typing. So I will just start with some pictures of the main items, there are a lot of little laser cut parts that I will highlight/explain as I get along with the build. The build photos are courtesy of the Paco Modell Website.

I am starting with the fuselage and need to get a build platform designed and built, but I did mock up of the fuse formers and its going to be fun! Talk soon.

Hello Guys,

Been working on getting the fuselage jig glued together and setup. I use a solid core wood door for my base build surface and typically put a 3/4" piece of MDF on top of that. I checked level on the table and over time, there was approximately 1/16" bow in the center. So I used some 1/16" aluminum bar to shim it up and it's within .010 to .005" of being perfectly flat again. For wood, I consider that good, since the wood will probably expand and contract as the weather changes, although its fair dry here in Idaho.

For glue I use Ponal Express and Classic, I order both through Amazon from Germany. The express is for quick layups and the Classic is for when I need a little extra time. The express sets up in about five minutes and both dry crystal clear for clean work.

Used a straight edge to make sure all the segments of the jig are in alignment during gluing. I cut down the MDF to 72" x 12" for the fuselage jig, mark the centerline and then screw the jig to the boardm using the straight edge to make sure it stays straight.

It's taking some time to get the parts figured out and the best approach to assemble the fuselage; I do not want to box myself into a corner. As you can see former 1a was damaged during shipment and I had to cut a new part out from 3mm Lite Ply. Formers 1 and 1a get glued together and become the motor mount, since I am building the electric version. Paco Modell, includes some nice 3mm threaded inserts that I will glue in later, once the hysol warms up.

Did some test fitting in the meantime and former 1/1a have 4 degrees of down thrust, that is set by A and T as pictured. It is close, but I don't like how they fit and I may have redesign them to get a better fit. I will say the laser cutting is nice, but the parts do fit a little looser than I like. I might have to shim some parts, but I have to think about the best approach.

I will need to to start cutting some 90 degree triangles for all the formers and 86 and 94 for the 1/1a former.

Couple of pictures from today. Thanks

This will update where I am at on the RCG thread (1 Feb). I will continue to post in both places going forward.

Hello Guys,

Before attaching the fuselage formers to the jig, I wanted to check alignment and it looks pretty good. A little tweaking, but I am not sure if that is my laser alignment or the actual formers. I don't have the highest quality laser alignment tool, but it works for me. I expect a little variation, its wood, but want to get it as close as I can.

Loving it! Thanks for sharing the build with us all!

Thanks Wayne, I appreciate it. Hopefully I will have some more updates in the next day or two.

Hello Guys,

Started working on the three sub-assemblies that need to be built before starting to glue the formers to the jig. First is the Motor Mount. In a previous step i showed were you glued T and Ta together.

Next, I needed to glue in the blind nuts. These are included with the kit. There are four for the motor x-brace and two for the removable front nose cone. Not much to really mention. I use BVM AeroPoxy (slow-cure) and when trying to get glue on small items with threads it helps to put a screw in to help hold it, instead of getting glue on your hands.

The motor was an optional item included in the motor/esc combo. No name on it, but it has D3548-1100kv and looks like the Turnigy or other variants you can find, by searching the web.

After curing overnight, everything aligned nicely. Next up will be Formers 7-8 which form the wing mounting area. More to come. Thanks.
