Supergee type DLG build

<< < (6/9) > >>

Richard Boyd:
Hi Joe , very interesting build.
You are a young man of many talents.
The wing came out really well and at 140g it is a good weight , my blaster 2 is 138g flying weight and I acheived this by using 2 servos in the pod. This gave me more forward weight and reduced the amount of lead I had to use up in the nose.
I also went rudderless  (6.5g) and used a spring pull elevator(7g).
I also shortened the boom by 22mm, my launch heights improved and the plane turns alot better in low tight thermals.
This all helped to elimate adding weight up front to correct the CG plus I have a plane that thermals alot better in low light lift.

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)

Richard Boyd:
Very nice indeed Joe !
I had some ideas on a dlg a few years back but it really is difficult to work on such simple yet complex planes.
I had thought about cutting the wing in half (on the length) and milling out triangular sections and then fitting the spar and sandwiching back together and glassing, I reckoned you could save 30g plus and improve the wing strength.
My old blasters are used on the sand dunes and sea walls around the North Coast, as you live beside the sea you will have hours of fun with your proto type. But be careful you mite get hooked on HLG  :wink:

Keep up the good work.

joe:
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 :)

Fred:
Looking good Joe!  :clap:  :clap:
