Thermal / Flat field / Supergee type DLG build

Am indeed Bill. Trying to use it sparingly. And what a lovely sound it too. Is it still available from the same place?

Hi john.
As long as i can just think Brucey, not actually wear the tights!  :D
If it's EPS you're after then yes. Blue foam is my personnel stash. 8-[

I usually don't weight mine either but they usually are slopers. With something like a DLG weight plays a much bigger role.

Yeah the launch definitely takes a bit of practice. Been a while since i flew one and they weren't great then either.

12 degrees sounds about right Bill. I plan to do a rudder/elevator version. Different airfoils though as the supergee airfoils are designed for flaperons and are a little unusual on the topside because of that.

So the most important questions. How does it fly? and then what weight did she turn out?

Getting there Fred. Getting there. :wink:
Mould is touched up. Need to sand a few little spots and wax her up then she is ready for use.

You're right Richard they are simple but not easy to work with. The cores are thin and delicate and it's a bit of work just to get something fairly standard like mine but, it is satisfying when they come out usable.
Plenty of small coast sites here when we get some sort of easterly alright.
Was kinda planing on getting hooked to be honest. Wanted to do a lot more thermal flying this year. Was flying yesterday in the field beside me and caught a few small little thermals. More like neutral air really. Have a really old hi-start/up-start type affair that an auld guy gave to me years ago. It's standard household bungee cord and is fairly shite. It only stretches about twice it's length so launch height was about 20 metres :-( Am waiting on some rubber from hobbyking. If i can get a decent launch height i'll get into using it i'd say. Then it'll be time to build a TD/F3J type affair!
Have a few machines that should work ok off the hi-start. Between them and the DLGs I should be good.....for now :)

Hi Richard.
So far so good. The idea was to build something that was at the standard of an entry level DLG and then try build better, stronger, lighter as I go.
138grams flying weight? just for the wing right?? similar weight but, your blaster wing will be twice as strong as my wing :D

interesting stuff Richard. I'm not going crazy trying to keep the weight down but i will save it where it's easy to do. Want an average build as a reference and i need to leave room for improvment! :D

Mould's done. Came out fairly good. One side is good and the other needs a little touch up. Can see where i went wrong. Lesson learned(hopefully)

It's very rigid John. Think laminated business card type rigid. Leading edge to trailing edge is fine as are rounded corners like the DLG wing. It won't conform to a square tip or crease would probably just crush the corners a bit. Depends on how much vacuum you are pulling i suppose?!

Fantastic JP. Really looks the part. Used the 3021 for the Aermacchi. A good profile like that should make a difference. Looking forward to finding out!  :clap:  :clap:

You assume correctly Alan. Very satisfying it was too. Thankfully  :D

Hi John.
The mylar is there to give a smooth surface so you have foam, fibreglass/carbon etc then mylar.

When you are doing the layup you actually do it onto the mylar and then set the core down on the bottom mylar and place the top mylar on top making a  sandwich with the wing core inside and all that goes in the vac bag. It gives a really nice smooth shiny finish like a moulded wing.

Wow! looks fantastic JP. You cut new wing right. What profile did you use?

So half of the mould and the canopy is now done. Getting there

Sorry to hear you back is giving you trouble again Bill.
They are a nice project alright. I have/am considering a R/S version. It would need a least 10degrees of dihedral i reckon to be responsive with rudder only. Thats a lot of dihedral! It would look a little extreme. Polyhedral looks better to me. But you would have to reenforce where the outer panels join which would add to the weight lost by not having any servos  :?:
Well I have 4 booms and will have a fuse mould soon so I can make a straight one and a poly one!  :D

First half of the fuse mould glassed. Now we wait.


Wings sanded and trimmed. 140grams. Not bad for first go.
