Well folks, 50mm for me is the magic number.

Did the maiden today and only about four clicks all around and she made ME look like a good pilot.

50mm from leading edge{most outer side of wear wing fits with fuse}, GO TO HER BOYS.

Good news indeed. Just a note for all out there. I'd recommend putting some thread lock on the motor mount screws, just to be on the safe side. On the Beta 1 version of the model one did works itself loose, so might be worth considering.

Longer aileron& flap cables please!

Not sure if anyone mentioned this yet, the aileron and flap servo cables are a bit short and should be lengthened for later production runs,, they need to be slightly longer, especially since some of us are actually setting up the Walrus properly as a fullhouse sailplane, with separate channels for each of the aileron and flap servos, but the cables are too short to fish through the fuselage and then need a short extension to be able to position the receiver in the fuselage, so I had to provide myself 4 servos extensions. Finished setting up my Walrus today, on my Futaba 9CHP Super, with a 7 CH receiver, so I have full 7 channels, with fully cambered trailing edge, and mixed flaps to ailerons for enhanced roll response, and of course Crow Landing for precise spot landing even in tight spaces.

I did thread lock mine.

LF - Thank you for the 50mm - (is this at the servo wire slots?)

DT - This is a new one on me "mixed flaps to ailerons for enhanced roll response". I am intrigued.

Spar Joiner Dimensions

To me the spar joiner feels easy to break.
I'm looking over the solid rod
and grab both ends and give a breaking motion with it.
It audibly cracks fairly easily.
I have doubts it's carbon.

Mearsurements for replacement of spar joiner:
Small rod - 5.5mm OD 300mm L (just shy of 1 ft) - This fits inside the wing spars.
Larger center spacer rod - 8mm OD 20mm L (3/4") - Fits over above small rod, centered and glued. This center piece is probably made from a piece of wing spar.

Wing Spar Length - 482mm - 19 in.
I assume the spar ID is 6mm. The joiner flops around in it pretty good.
It appears the spar OD is 8mm. I can't get directly on one to measure.

Here's some solid 5.5mm carbon rod I found and need to order.

Here's a 8mm hollow rod with 6mm ID:
http://www.rcfoam.com/product_info.p...5cc12cf7910834

Is there such a thing as 5.5mm arrow shafts? just curious... this joiner looks like fiberglass rod to me.

NOTE: If you look under your wing and see the slots at each end running front to rear, that is the end of each spar.

Spar Reinforcement

The 5.5mm Solid rod sold above is 39" long.
The wing spars are 19" long.
19 + 19 = 38" + 1" center spacer =39"

Instant full length spar reinforcement!
Just glue a center spacer in place in the middle of the 39" rod.

WELL DUH!
You should not need the center spacer at all with the full length rod.
All it's for is to keep the short wing joiner from dropping into the wings.
TRUE?

Yeah, this is fairly standard with sailplane setups, with this mixing , the entire trailing edge moves for roll control

I pushed my Rx back behind the rudder and elevator servos. Not really happy with it but its out of the way...a bit.
I was going to velcro it down but I can't reach back there to fit the hooks.

That's exactly what I did, no problems and it was as far away from the ESC as possible.

Good idea, thanks for that.I think i migh have a soloution for the not getting it stuck down part .Get your stuff plugged into your rx, apply the supplied velcro{or what ever you use},but you gotta put both bits of velcro on at the same time with the peel and stick part removed,grab a long set of neddle nose pliars, find the spot where you want it and press firmly with the tips of the pliars to ensure adhesion from velcro.
Sorry for going on
