Well, that bit of plan fits on the board.

 

 

Just! and that's only the tailplane. What have I started?

🤣

The fuselage cut parts came today, Sunday, and I couldn't resist checking them out. Which led me to the tailplane as the ribs are included. Then as I have been advised I could start on the tailplane as it's an easy way to get back into building. The building board is empty and not needed by Peggy Sue II.

 

What to do?

I still have not worked out what this means.

How did you learn to fly and when?

[Slope soaring, an ideal entry into learning to fly RC model aircraft?]

The advice being given by the OP gives me the impression that a beginner buys a model, throws it off a hill and instinctively will be able to fly. We all know that is not the case.

@Rich Griff how did you learn to fly and how long ago?

I'd qualify that by saying not an ideal entry into learning to fly RC model aeroplanes on the flat field.  IF you want to learn to fly slope soarers on the slope then it would be ideal. 🙂

True but only if tuition is available.

Looks like we all agree that slope soaring is not an ideal entry into learning to fly RC model aeroplanes.

If you have had a vimto or 3, sleep on the topic and debate in the morning, when you are sober.

Obviously this advice doesn't apply to you as you are posting and advising after three vimto/Tetleys.

Slope soaring is great fun and well worth anyone who hasn't given it a go, to get out on the hills and do some slope soaring. It can be a good introduction to model flying, but it is not the same as flat field flying. For someone who is at the early stages of learning to fly a conventional, flat field model much of the flying on the slope is intrinsically dissimilar - the skills and muscle memory it develops are different.

Absolutely correct leccy. There are plenty of slope flyers on here but only one keeps advising flat field beginners to go flying on the slope. If a beginner is not competent enough to save themselves when difficulties arise then on the slope broken models and long walks will surely be the outcome.

 

On the other hand, if a beginner starts on the slope, with help and guidance from instructors, then they will learn and have fun.

I have been working on the tail and here it is.

 

All dry fit, of course.

 

Now back to the front. Unless I fit the wing servo trays.🤔

Steve, you might consider shortening the nose a little.

For the spinner to be in the same position as the plan the engine mounting former needs moving back 30 mm, but I could easily make it 50 mm, more to think about.

One wing, at last. 👍

 

 

I can now put this build on hold while my mate John catches up.

Onto Peggy Sue II for a while.

There's your answer, Steve, and much more eloquently than I would have said it.

I experimented with the Mini Super and found exactly as John said.

Downthrust may need changing dependent on the pitch, when the model is first flown.

Incidence will be fine, as the plan. 

 

We have two SLEC model tables at the field.

Steve, you'll find that many of DB's designs followed the same style of construction.

I had the sane thought Nick while I was looking at the fuselage it's a bigger version of the Mini Super. Which made me check the wing incidence and downthrust. Incidence I calculated to +3.8 degrees and downthrust 3.5 degrees.

 

If I changed downthrust to 0 and incidence to +0.3, or any combination, what would be the effect and why?

After studying the plans, I have ordered some wood. This exercise brought some questions in my mind, so I searched online for some previous builds, unfortunately this only increased the number of questions. No rush though as I am 'crossing bridges' that are miles away.

 

I have to finish Rhapsody, Peggy Sue II and keep ahead of @bodgerep (John) with The Ohmen.

 

Plenty to do!

Steve,

I'd advise building the wing as it was designed by David Boddington. A flat wing will not only look less pretty it will have no lateral stability. It simply won't fly as nicely, tending to wallow all the time and needing constant aileron (and rudder) correction.

When completed, If the cg is a bit forward, it will add to pitch stability which will help with the easy flying characteristics, you may just need a little more 'up' elevator range.

Looking forward to seeing this one.......     

Thanks John,

I was being lazy and looking for quick assembly at the field.

I am in favour of easy flying that's why this topic is in Trainer kits. 

 

I need to order some four-foot lengths of wood just to cut down on the number of splice joints, not that I am lazy BTW🤣

 

 

[The Ohmen]

I thought the aileron was finished but on moving a clamp from the en to the centre.

 

Just more plane and sanding led to this.

That's better.

A bit like my Bristol, carbon tubes slide into tubes in center sections and wings. A single screw goes through a plate fitted to each wing into a nut on a plate in the center section.

That's exactly how I thought.

Will no dihedral (flat wing) cause a problem, second thoughts creeping in?

The treatment starts with a sharp knife for a bit of whitling.

 

A few big bits.

 

Then I used my plane to get a rough size, making sure not to go too far.

 

A bit more plane, I think.

 

That's close enough with 1/16" at the bottom and just not touching the top leaving it at 5/16"

Next, I held it in place on the TE for a close shave with the plane.

That will do nicely.

 

After a bit of sanding.

 

It's ready for the TE to be cut off (98 mm) and glued. Leaving the remainder for the aileron.

 

That's next then fit the hinges and finish the wing tips.

 

Steve

[DB Mighty Barnstormer]

Studying the plan shows I have most wood in stock except the 5/16" square balsa so the good news is that I can't add to my pile of wings from unfinished projects.

I am thinking of making a three-part flat wing. The middle part being across and permanently fixed to the cabane struts.🤔🤔🤔🤔

 

Steve

[The Ohmen]

Cut and shaped the first TE/aileron,

 

The second is at the top, wating for the same treatment.
