build Peggy Sue 2

[Peter Miller]

A balsa Stripper is a much quicker method, 36" long strips of accurate 1/4" wide strips.  The Master one is great, The same was also made under the Kavan name.

[EarlyBird]

The top cap strips are coming on.

 

First wing done and

 

 

Parts cut for the second.

and done.

 

 

Then I turned the wing over to do the bottom. 😕

 

Not good where the three 1/4" ribs are particularly the centre one which was something like 1/32" above the aileron spar, the same for all three between the aileron spar and trailing edge. Added balsa where needed and sanded down as required.

 

 

Then hid it all with the centre sheet so no one would know.

 

 

Bottom cap strips next.

 

Steve

[EarlyBird]

Cap strips done and trailing edge along the centre section between the ailerons. This made it time to tackle the first wing tip.

 

 

 

I laminated balsa as on the LE and wrapped it around onto the aileron TE then added the aileron TE. Thanks for the idea @Ron Gray. Worked well and not difficult at all. The other tip to do then LE cap strip which will be shaped and the tips rounded to match.

 

Well pleased with that 

 

Steve

[Peter Miller]

That look extremely neat

[EarlyBird]

Thanks Peter,

 

Second wing tip

 

 

and LE cap strips added

 

and sanding started. Bottom first then top.

 

Steve

[EarlyBird]

LE top

 

 

and from the front

 

 

The top now looks about right so turn over and make the bottom look about right. Then if there is any flat blend the top and bottom to form a curve, I have the sand paper ready.

 

Steve

 

 

 

 

[EarlyBird]

This now looks about right, from a distance, but on close inspection there are a few flat spots, particularly at the wing tips.

 

Next will be the wing tips then!

 

Steve

[EarlyBird]

Wing tips done and wing added to the pile.

 

 

but resisting the temptation of a new buid

 

Hound Dog is almost finished.

 

but on with Peggy Sue 2 ☺️

Like a factory in China Steve. 🙂

[EarlyBird]

Thanks John, I will take that as a complement 🤣

There is a reason for the pile of unfinished models, indecision.

 

Been practicing making joints.

 

Plenty of good practice because only two pieces are the same length and angle.

It usually looks better when glued and sanded, lets hope so 🤣

 

I need to make decisions about the engine fit with regard to the position of F1 as I need to move it back 15 mm for the prop and spinner to be in the same position as on the plan. If I move it should I move it further and by how much to achieve the plan CoG? To give everyone time I will either finish Hound Dog or start Basic 3D. I could finish these side frames though, good idea I will continue with the joint practice.☺️

 

Steve

 

[EarlyBird]

All parts made for one side.

 

 

Glue next or cut the parts for the second side?

 

I have been thinking about the engine fit. It will have to be side mounted and moved back up to 50 mm. 25 mm sounds good to me 😕

 

Also I have two other models I could use it in and by pure coincidence they both have 3548 motors, and underpowered IMO. Another consideration is that the FG11 needs running in. Too much to think about and so I will keep building as the plan and make a decision when I absolutely have to.

 

Who said building was easy 🤣

 

Steve

[Ron Gray]

Glue side A then build side B over the top of side A.

[EarlyBird]

Did as you said Ron. Added clear plastic between the two, seemed a good idea. 🤣

 

 

Nice bit of detail Peter.

 

 

Just the ply doublers to add then on to the fuselage jig. More fun to come.

 

Steve

[EarlyBird]

Ply doublers added and F2 glued.

 

 

Then indecision struck again so started something that had been waiting and added to the pile of wings.🤣

 

 

Feeling guilty I returned to this build.

Battery location on F4 set up.

 

Holes drilled for cable ties.

 

Then F3 and F4 glued in place

 

That wasn't hard as no decisions were required.

 

Steve

[EarlyBird]

Added the other side then checked for alignment, made adjustments, checked again when satisfactory glued in place.

 

 

Then checked again just to make sure. ☺️

 

F1 has not been fitted because it needs moving back for the FG-11.

 

Steve

[EarlyBird]

Just put it in the jig and for the first time ever everything lines up square. I must be getting better at this lark. 🤣

 

Steve

[EarlyBird]

Coming to the end of the jig work with just F1 to place and trial fit the engine.

 

 

First time for me so not that sure of what I am doing and there will be plenty of thinking time.

 

Steve

[EarlyBird]

Checking how the engine will fit, side mounted.

 

 

Looks fine so I will go for that and drill the holes. F1 needs cutting to size.

 

Steve

[EarlyBird]

Engine mount fitted to F1

 

and test fitted to the fuselage

 

 

Having deliberated for a long time over how to mount the engine I found out that the bolt holes are in a square 45 mm apart. 🤣 No need to make a decision now. 🤣

As this model will be for a beginner I think that down thrust and side thrust will help. How much? I am thinking 2 Deg. down and 2.5 side. Any thoughts?

 

Steve

[Ron Gray]

Personally I wouldn’t bother but if you’re going to put some in (from memory Peter doesn’t) I would suggest a max of 2° downthrust and 1° sidethrust. My Peggy Sue 2 (electric) hasn’t got any and flies just fine.

Edited August 3, 2023 by Ron Gray

[Peter Miller]

I never use side or down thrust.  The original smaller Peggy Sue that has been built in the club doesn't have any.The big one that was built in the club doesn't have any.  The one flown in a howling gale on the Peggy Sue thread thread and which was described as "Out Wot Fouring a Wot Four and Out Acro Wotting an Acro Wot. Didn't have any....But of course with your vast experience you may know better!!!!!

That's just the point of asking, I have very little experience. It was a request from an instructor, my understanding was that he would prefer side and down thrust for beginners to fly straight and level hands of, something to do with building confidence. Why adding down and side thrust enables hands off straight and level flight is beyond me.

 

Interesting about Peggy Sue because he flies one and loves her. I will ask him again.

 

Thanks

 

Steve
