I have stopped building the G2 to focus on the Hawaiian Hawk and XL 2 which is a 130" open class TD ship.

All my new models are going back to wood veneer over foam core wings like back in the 90's. Focus on fun and good value for the kits and with some actual building involved.

Some shots of my other project the "Hawaiian Hawk" an updated Hobie Hawk for 2017.

Span 120" Rudder, Elevator Flaps. Basswood veneer over Blue Foam wings and tails.

Good Fun!

I have been occupied with the house and still doing work on it interspersed with some shop time.

Currently I am making a new bottom surface wing mold for the 3rd time. My wing process is not compression as is the usual these days. For that you need CNC cut molds and cores.
My cores are Blue foam hot wired and shaped with templates. The bottom plate or mold is flexible instead of rigid. Its not mylar but a thin glass layup which incorporates the leading edge and wing saddle recess. The mold is then put into a bag and vacuumed down under pressure in the rigid top mold.

Its been trial and error for quite awhile as I made the original plate too thick and it was not making contact with the core sufficiently leading to some small places that would be delams.
After making a more flexible test plate I have solved the problems and am now making a better quality bottom surface mold saving thousands of dollars and many lives in the process....well at least thousands of dollars in reject wings!

I will be making some G2's for sale in the next few months. Its not going to be a production item but I will build some to sell.

Work on the G-2 has been postponed for a few weeks due to a very neglected house!
I have been deep into painting the inside and after a week of work by myself painting the living room and master bedroom, the wife came home from vacation on the mainland for that week I was painting. We both decided that the color was wrong and it needs to be repainted. So, throw that week away and start over.
Also prepping the exterior for a crew to do the outside.... No fun for Dave for quite awhile it appears.

Greg has been doing a great job at sink rate testing and I will have him post his findings here as things go along.

The G2 is being flown by Glidermang in New Mexico right now and he will be taking it to the team trials in Muncie next month.

Last weekend I had Joe Nave bring his big camera to the field to shoot some flying shots of the Ghost 2. Joe does all the photos for me for the last 10 years of my DLG models.

The G2 is the best flying glider I have ever flown. Im a fan of the tri-hedral wing design and have used it for many years on my TD gliders dating back to the Predator XL I produced in the late 90's.

I didn't think it was possible to have this in a DLG so never pursued it. Some time back in late 2014 a friend named Chris Parkyn contacted me about some really interesting things he was trying out on his low wing design.
He has a good friend by the name of Jack Chambers who was having Chris cut his wing and bend it up to a set dihedral angle. This was flown and while it did show an improvement in stability and circling wasn't all that great.
Jack then had him cut the tip and bend it up to another angle and then things really started to improve.
I will cover the whole story for groups when this glider is ready for independent testing and review from glidermang. Its a great story and has taken a long time to get the G2 out.
Any questions you can contact me here.

This wing was out of the mold last Friday for Glidermang . This is a light layup and seems to be right on the money for strength at this weight.

I have been flying the G2 for the last 3 days in perfect testing weather.
Down to the park by 8am before the thermals really start to pick up and do the shake down trim and handling test.
Having built so many versions of this plane, sorting out the best and worst of camber and reflex settings was a simple matter.

I am now building parts to assemble 2 G2's for Glidermang in New Mexico for evaluation as I have done for my other ships.

This project has been under wraps due to the design being way different than whats been built for current DLG's.
Its not new in the world of gliders by any means but new for us.

I will let Greg do a review of the G2 in Groups but there will be no build log as there is nothing to build just install your gear.

More to come,

I have flown the G2 a couple of times briefly and discovered a massive flutter issue due to the torque arm flexing. A rebuild of the aileron drive and adding a pin in the pivot point similar to the Snipe solved all the flutter.

Sunday was actual test day but conditions were very windy and turbulent.
I used only a 1 ounce ballast slug and found penetration to be more than expected in the 15 -20 mph winds.
First impressions were that it was very slippery, climbed well and runs extremely fast and flat. Even brought it home in one piece which was dicey due to the low level turbulence.

Winds are dropping off later in the week and I will get a chance to wring it out in normal conditions.

Im still working on the fuse quality and decided to show the mold Im using.
This a typical mold for me except that the glass thickness is twice as thick.

End grain balsa for the flange capped with more glass. Very durable and light compared to what Im seeing other guys use.

I have been piddling along working at a slow pace on the Ghost and learning all about bladder molding this last week.
Im getting close after the 4th fuse pulled. Weight is 38 grams with the nosecone but need a little more work on the finish still and Im sure I can pull a bit more weight out of the boom which is very stout.
On a side note, All my molds are epoxy & glass and my fuse mold while double the normal thickness for the pressures, hold up perfect to 60 psi pressures with no yield at all. The idea that you need a bulky heavy mold to handle the pressures is just false.

Finished the new fin plug and working on the parting tray.

The wings are very nice and Im getting close to the weights I want. One reject turned in at 115 grams and one at 128 grams. I believe I have the layup I need ready for the next wing. Shooting for 115 grams and perfect. This is on a 315 sq. in. wing so I feel this is pretty good.

Well, not even close to having a flying Ghost yet. Looks like I have to make another rudder mold and I took some time to add Hinge Line fences to the wing mold. Two steps forward one step back!

Pulled the first test wing out of the mold today to check for core adhesion
and fit . Awesome !

Molds are done and will be learning the production process for this set of molds right away.
I should have a flying ship within 2 weeks if all goes well. Then production starts.

Its been taking slightly more than forever to get to the resin and cloth stage for the molds but its happening right now!

Here is #4 of 6 flying prototypes I have been working on. This is not the final version of the Ghost.

The Ghost #7 is in the molding process right now. No date as to when it will be ready.

Im happy to announce that the new owner of the Arrow series DLG's has spent the last week with me at my shop.
He is new to bagging but has the drive to put in the time to acquire the skills needed to put out a nice kit.

I will leave it up to him to announce when he's ready for all the attention. It should be a few months before there is any product for sale.
There's shop set up and materials to purchase etc. Also run through quite a few reject parts before it all settles down.

His new business is called "Atlantic Glider Works"

I will be updating this thread as info becomes available.
