Proposed aileron servo set-up.
Advantages:
1- uses existing aileron bellcrank plywood support with matching slots in the ribs.
2- servos can be fixed/screwed onto the platform, photo 06.
3- covering can be applied to the plywood.
4- minimal additional drag caused by the protruding servo, photo #07.

Disadvantages:
1- adding a former to support the covering fore and aft of the plywood, photos 08 and 09.
2- servo located near the fuselage (risk of aileron twisting?!?) but that is where the plans call for the aileron control to exit.
3- need to drill holes for servo extension (holes will also be needed to the ESC and battrery cables), photo 07, 08 and o09 clearly show the slots through which the spars pass.

Elevator completed, except for shaping and sanding the tips.
Wing started, just trial fitting parts.
The front and rear wing spars are 1/4 think with a 1/16 spruce cap.  They are STURDY!
Aileron servos are the fat Hitec HS-125MG. The low profile of these servos will allow mounting flush with the wing bottom surface.
I bought the last supply of Kleet hinges (3 packs of 3) from John's Hobby shop. I was informed that they are ordering more...
As a final note, I think that I determined how the EDFs will be mounted to the wings (to be described in a future post).
 
Photo #97 - dry fit of parts.
Photo #98 - a spacer (not glued) used for the center section.
Photo #00 - Center section sheeted.
Photo #01 - Dry fitting of parts for the right wing.

General Discussion / Bumpy Grass Runway
Last post by davidk - Yesterday at 05:05:59 PM
For anyone who's noticed, we have a very bumpy grass runway... since about October.  I thought it coincided with the last time the field was cut and maybe Brian had aerated the grass.  If you muck with a mound you'll see a tiny hole which, again, I thought had been done by something mechanical.

I believe these mounds are worm castings.  This means we have a very healthy grass runway... well... healthy for anything except airplanes... especially with small wheels.

I've done some research and it's a very common occurrence, although I've never seen it before at TEMAC.  The image below is not from our field but just a random photo found on the web... and it matches what we have exactly.  If it happens again next year maybe a fall roll will help.

Fuselage completed, almost.
Rudder and Fin done.
Much sanding remains to be done.

Next elevator: the main spar was flimsy balsa that snapped and is being replaced by a scrap piece of rigid 1/4 by 1/2, laminated  with 1/16 for a 5/16 total thickness.  This will be fine sanded to fit the slotted stabilizer ribs.  Pictures to follow when assembly starts.

PS: I dropped a small set screw for the servo pushrod connector and it vanished in the ether. Trying to locate a replacement...  HAAARRGGG   >:(

Quote from: Frank v B on October 22, 2024, 06:17:57 PMThat was a superb day provided you were not intimidated by revengeful winds.  They were as fast vertically as horizontally after interference by the trees behind us.
Yet despite the challenges, some members had superb landings.
Thanks for the dogs.

@Frank v B


My absolute favourite flying conditions!  I so wish I could have been there, if only to make @Frank v B cringe and purse his lips!!! 😂

Did anyone take a wind measurement?  What was the wind direction!

This is excellent Guy!  Thanks so much for sharing this.

They just need to get Adam Savage to stop behaving like a child (not to denigrate children!), or remove him from 90% of the video.

Trading Post / Re: FS: Crazy 8 balsa plane
Last post by Frank v B - October 24, 2024, 11:08:23 PM
Greg,

I believe the Crazy 8 was a balsa ARF put out by Wattage Models.  They were the first balsa electric ARF's on the market and included the Cap 21.  They were designed for Speed 480 geared brushed motors on 7-8 cells in the NICAD days (7.2-8.4 volts).  They flew quite well as brushed models. They came out in about 2007.
They would be great flyers today on brushless motors and Lipo battery combinations.

For what it is worth.

Frank
ps: will look in my shop in my plan/magazine archive in my shop. 
My shop makes my car look pristine and organized.  ;D  Everything in life is relative.

Update: confirmed it was by wattage.  34" span mid-wing model.  Here is a listing on E-Bay https://www.ebay.com/itm/135178183783  It has photos of the box.

Its yellow, Eric might have grabbed it at one of our swap meets, $40?  Its in great shape, but no electronics, no landing gear.
looks to be made by great planes.
