Hover King Maiden Flight

We finally finished Hover King in time to do some test and trim flights. She flies nicely off the hi-start with no apparent vices. Floats rather nicely but can really speed up when you put the nose down; a nice surprise since I never flew anything with a GOe 549 airfoil at 13% thickness.
My facial expression is just the tension I am under.
I really have to lose some weight! Bob Galler is in the background readying his hi-start.
That lifting horizontal stab was really no big deal. Who knows how far back I can set the CG? It was 40% this morning but we did tweak the tow hook back about 1/8".

Hoverking Wing Progress

 templates on 1/16" plywood

wing plan and rib templates - notice the right panel is a mirror image of the left

Old riblets (top) and new output from the revised template - Simply added 1/8" to the back of the riblet template. (Gilbert called his nose ribs "riblets".

Hoverking wing detail for 1/8" balsa shear web and W-1N riblet coming in the spar caps by 1/8"
I thought a lot about this because I wanted the shear webs to tie it all together.

Well, that about all for now. I should be stack-sanding the balsa ribs soon.

Very truly yours,

Hover King glider is under way

Here are the first rib templates for Hover King. Peter Gilbert used the GOe 549 and I worked it up in Profili, then I output to TurboCAD as a DXF file for final tweaking. After proofing the output, I printed the first ribs (and what the designer termed "Riblets") on card stock paper.

See you next time.

Center panel covered

Here's what the completed center panel looks - UltraCote Lite colors: transparent red bottom and transparent white on the top.
I'm holding the panel with the sun just after high noon. The transparent red really "pops" as I'd hoped to see.

Now forward, to victory! (Well, at least to the maiden flight.)

Very truly yours,
The Comet Kid

Yellow Jacket covering layout

So here's the covering layout that I sketched for the Yellow Jacket 2M.
Mary and I went over it together. The goal is to really make it pop in the visibility department when
this glider is at altitude.
The overall plan

We'll see how this all goes in the real world.

Sincerely,
The Comet Kid

AMA Indoor Nats - Eagar, AZ

Mary and I visited the AMA Indoor Nats at the Round Valley Dome in Eagar, Arizona. I'm posting some of the photos I took.
Yours truly;
The Comet Kid
The Round Valley Dome is impressive; the skylights often provide indoor thermals - yes, I said thermals
Dave Aronstein winding for a test launch of his No-Cal Gloster Meteor. His test was impressive as he went on the win the event for No-Cal WW II Warbirds
Dave Lindley winds in preparation for test flying: Dave later took my application for NFFS - first time I joined

Mike Richardson relaxes behind his model box; an apt description of Free Flight
Dave Wagner and his models before the competition starts. Dave is with the FAC Rio Grande Squadron.
Rick Pangell with P-40 No-Cal - neat printed tissue. Rick later convinced me to join NFFS and I did!
Rob Romash with his No-Cal Chambermaid - he'll take the Greve/Thompson mass launch with this model
The Kamikaze Phantom Flash; I thought this showed some real creativity. The tissue must have been done on an ink-jet printer

Bob Galler and Dave Aronstein's jumbo scale MiniMAX. Bob was holding for Dave. Yes, that is a profile pilot of Kermit the Frog.

Rhinoplasty - Big Bird electric returned to the pure sailplane form

I decided to change my Skybench Aerotech from an electric powered glider back to a "pure" sailplane.

Here's the nose section receiving a nose job.
Here's the nose starting to be restored to the pure glider shape.
Blocks ready for final shaping and sanding.
Now, that really looks better. Don't you agree?
Rats! I had to hog out the nose block to install the lead weight for a rough pre-balance.
It was kind of like carving a Halloween pumpkin by slicing off the top and scooping out the balsa with a Dremel.

You can see how carefully the balsa was cut and reglued.
Now we have the Hitec servos, Optima 6 receiver and the LiFe battery pack for more pre-balancing.
Here's the final form after all the work. It's heavy but it balances and I like the look. Big Bird 100 designed by the late Ray Hayes.
