Dynamic 40, 60, 80 and beyond!

Just realized we didn't have a thread here for the Dynamic series of planes. Time to fix that!

The Joe Manor is an iconic glider for the world of Dynamic Soaring (DS). Capable of amazing speeds and built for massive strength, these planes are no joke. You need some good slope experience before you attempt to mess with one of these, but when you are ready, these planes can really deliver. The big boy of the family (over 40 lbs), the Dynamic 130 has a recorded flight speed of 514mph. The D80 holds a speed of 453 mph, D60 = 360mph, and the little D40 is just a bit behind at 305 mph recoded just last year.

But it is also much more than raw speed. Many people enjoy the smaller D40 and D60 gliders as dedicated front side gliders that will handle a ton of abuse and cary lots of energy. (The bigger planes are not a good option as their airfoils are for pure speed.) We noticed this trend and now offer new versions of the 40 and the 60 just for the front side pilots. At least that was our original intention. We call these the F40 and F60, the F stands for Frontside, as in the frontside of the slope. We use the same exact molds as the D versions, but we change the layup and use modern spread tow fabrics to keep a lot of the strength while saving a lot of weight. Then we added some area to all of the flight surfaces to make the planes a little more fun. This means bigger ailerons, flaps and elevator. Now imagine a plane that weighs less, and can land slower, but still offers pretty insane strength. I think you get the idea.

F40 prototype.

Then we handed the prototype F40 over to our tame test pilot Bruce Tebo. I asked him to test it out on the frontside of the slope and report back. He did and all was going well, he couldn't help himself and clocked a speed of 194mph on the maiden flight! The next day he clocked in at 217, and then a speed of 240mph. Wow, not bad at all. So even though we lightened the plane, she still turns great speeds. I doubt many people in the world could fly a 40" plane to this sort of speed, these are really small planes.

Next up we gave the 60" version the same treatment. Then Covid broke out and we had to wait until shipping of planes was permitted again. We finally got them in and we sent an F60 off to Bruce and he has been flying it with great results. As he says, the light weight (AUW=49.6oz) makes him think he forgot to add something to the plane, just feels lighter than he is used to for a 60. He has been able to fly it in lighter conditions than a D60, it lands with better authority and slows down (or even fly backwards) with the larger flaps. So far I think he has the plane up to about the 250mph mark with no issues.

We are looking forward to more reports on the F60 as we did sell several of these, they sold out FAST.

We will be altering the tail layup a bit on the F60 as we think we can get them stiffer and lighter, thus saving even more weight.

We just got another shipment of D80s in today, so those are up on the site. They are beasts!
 
I am a well satisfied D60 owner I fly with it on the front side and lm impressed with how good it is.
Thought to show some pictures from the construction.

Do you have recommended control throws, CG locations, for the D40 in particular? I am sure the other aircraft particulars would be of interest to some builders.
 
Installation of tail servo. I used KST 135 everywhere.
The servo is in the way so the rod can not jump out.
The rod is 1.6mm stainless steel welding wire

I do not have any D40. I have D60 and one D80 which I work on now :)
I usually have hi rade the maximum that is possible to get out of the model and start with expo 65 and then you see. and try it out what is best for you.

If you use openTX Radio so look here https://rc-soar.com/opentx/setups/f3f/index.htm

Looks good - I like that servo tray setup! Mind if we print up a few for the kits?

Bruce Tebo just let me know that he got a new speed for the F60, 294mph. Not bad for the lighter weight plane. He did beef up the elevator as he had been getting some flutter. We are adjusting the construction for all future F60 so you don't need to worry about this.

Of course print as much as you want :)

This is from last Saturday wind direction was not the best for the place that day.
Should be right on But we had to try anyway.

We stand there as the red dot is on the map.

My cameraman did not have time to record he wanted to fly to only the beginning is on 16 sek in lift kicks in
When the wind comes straight on with 40 mph average speed it is Lot of fun :) (y)

That is a heck of a site. Guess you are out in the wind the whole time there. What an amazing place. I love that photos of the D60 sitting in the snow. I can honestly say not many D60 will see the snow, and if they do it will be just a small dusting.

Looks good so far. I prefer to weld the battery tabs, but as long as you don't get the cells too hot you should be fine. Be sure that the tabs are really secure, heard some folks that suffered battery failures from the G loads when crossing the shear layers in the DS laps. The nice secure tray you have here should help a great deal!

Very nice. Ho do you like the MKS for the wings?
I bought it to be one of the best in the market. The quality is high is noticeable how good them center and running silently.

And those are in installed in Spencer Transonic to so I was no question :)

Could not find short steel servo arm which fit. Similarly them on HV6130H

Are you aware of this style of hook up? This gains back a lot of lost servo resolution.

Yes, F60 and all other Dynamics are being built up and should have more inventory in a month or so. Got really close to ordering in a D130 for inventory, shipping estimate was reasonable.
