Flyerman999 Posted August 26 Share Posted August 26 Hi Guys I recently bought a Pegasus 2m V Tail. I’ve been flying Nitro and electric planes for a while now. I fancied a challenge to build my own glider. Long story short, the build instructions for the Pegasus are appalling, there’s very little detail on how to build it. I’ve mounted the Ailerons and Flaps to the wing sections, and that’s as far as I’ve got. The next section is to mount the micro servo in the wing for the Ailerons. This is where I’m getting stuck. For the life of me I can’t work it out. Has anyone built one, or does anyone have one? I would be extremely grateful if someone could post some pictures on this thread showing how the aileron servos are mounted. Thank you in advance. regards.

DaveH Posted August 26 Share Posted August 26 I fitted one out, I still have it. I can't remember if I followed the instructions, but this is what I have now. The aileron servo is stuck (glue or good double sided tape) to the servo hatch cover... Dave Link to comment Share on other sites More sharing options...
DaveH Posted August 26 Share Posted August 26 I recall that the flap servo was fun to set up. Other users have told me that, if they built it again, they would just fit one servo to each flap rather than mess with the central servo. My flaps are a little warped, so individual servos would have helped. My biggest problem was the mounting of the V tail. It involves glueing the two tailplanes together, then to file/cut a half round slot in the underside of the joint and glue onto the boom. It didn't go on true and I had more fun trying to correct it.

Flyerman999 Posted August 27 Author Share Posted August 27 Hi Dave Thank you so much for the photos. I really do appreciate you took the time to do that for me. Unfortunately for you though, I’ll be asking you lots of questions going forward. (I hope you don’t mind.) I looked at the build instructions again last night. Some areas are ok, but by and large the majority is just awful. I’ve got a Fusion II funfly for an over winter build. That’ll be a doddle to build, the instructions are so well produced. Once again, thank you very much. regards Steve. 1 Link to comment Share on other sites More sharing options...
DaveH Posted August 27 Share Posted August 27 The version that I bought was the ready covered, "ARF" model. There is an ARC (uncovered). Which do you have? I used mine for F5J 2m class comps. It flew well, but I could never really get on top of trim issues. I believe that this was probably down to warped flaps (maybe ailerons too) and a misaligned V tail. I didn't get to correct it as I became involved in the Open class (4m) F5J comps. The flaps are controlled by a single servo in the fuz and are linked with a pin. This can't be adjusted. If I were to fit one out again, I would take more care in ensuring that the control surfaces were flat and mount the tail some other way. Next time, I might 3D print a V tail mount. I could try the single flap servo thing as it's fairly easy to retro-fit individual servos. Link to comment Share on other sites More sharing options...
Flyerman999 Posted August 27 Author Share Posted August 27 Hi Dave. I have the covered “ARF” model. I bought it because it was £150. They retail nearer £240 now. I was really annoyed with the build instructions. Maybe the Czech instructions don’t transfer very well into English? I’ve a sound engineering background, but this has really thrown me. I fear it could be £150 wasted.. the VTail construction is worrying me too. I might well take your advise and use individual flap servo. Thank you. Steve.

MikeE Posted August 27 Share Posted August 27 Glancing through this thread, For a single flap servo, the arrangement is very similar to my ProfiJ. A simple L bend to the flap horn works very well. It allows for very easy wing removal. You just need to make the fuselage exit point small enough so that once the pushrod is connected and the wing screwed down it cannot move sufficiently to the side be able to come disconnected. For the wing servos, I would consider blocking out the wing servo bay with blue foam then hollowing out a recess for the sero to slot into. Solid, light and removable.

Pictures paint a thousand words, nothing on that forum. I did ask the same question on that forum after looking at the thread you kindly shared. After asking if anyone has built one etc….the one reply I got was “I have.” How helpful. Link to comment Share on other sites More sharing options...
Flyerman999 Posted August 27 Author Share Posted August 27 Nicholls. I tell a lie, I just went back into the forum. I have found lots of photos. I’ll have a look at them. Thank you. Steve. Link to comment Share on other sites More sharing options...

Hi Dave. Sorry to be a pain, with regards the ruder control on the V-Tail, do the control rods come straight out the back of the boom, or out the side of the boom to the rear? Thank you.

DaveH Posted September 20 Share Posted September 20 Again, I don't remember what the instructions showed. I used to make great efforts to exit the rods from the end of the boom, but it becomes difficult to set up. On my Pegasus, I made the rods (& tube ends) exit the boom just behind the LE of the tailplane. Link to comment Share on other sites More sharing options...
Flyerman999 Posted September 20 Author Share Posted September 20 The instructions are shocking. I’m at a loss now. (Can you tell this is my first ever build) If and only if you have some photos available, would you be kind enough to upload some of the rear ( like you kindly did with the ailerons) that helped me out no end. Please don’t worry if it’s agg. Thank you. steve Link to comment Share on other sites More sharing options...
DaveH Posted September 20 Share Posted September 20 Here is an image of the control rod exit of my Pegasus. I made the slots by drilling at right angles to the surface then elongating the holes with a rat-tail/needle file. My control horns are made from pieces of credit card and in this case doubled to two layers as I didn't get the hole far enough forward. I generally provide some support for the control rod outers (snakes?) in a couple of places in the boom to reduce/eliminate possible flex/waggle in the control rods. In my Pegasus, I recall pushing in a couple of pieces of soft foam at spaced intervals to do this, giving some gentle pressure on the outers. I don't recommend the horn and inner rod termination that I used, it came out a little less than streamlined, but was easy to set up. Link to comment Share on other sites More sharing options...
