Here's the first mockup:

http://www.anjo.com/rc/aircraft/dragon/dragon.mockup1.jpg

No hatch yet, and no engine on the rear. Stabilizer simply resting on top with a round lead weight to keep it from blowing away. In actual fact, it fits in a slot anout 2/3rds of the way down, but it hasn't been cut yet
(the slot). The stab looks small, because the elevator surfaces which are quite large themselves, have not yet been fabricated. Also, there is an
extra lamination to be added to the bottom of the stab which will
strengthern (and thicken) it a bit.

Nose-cone under construction, laminated from several layers. It is a bit tricky, as when finished it is in two parts that are bolted together, and there is a pocket for counterweight lead. I've let in a hardwood block,
and tapped it for the bolt, and drilled/carved out the counterweight
cavity. I have also made a mould that I will use to cast lead weights to
fit the cavity snugly.

I'm going to need a Sullivan 8-ox fuel tank, which I'll have to order from Tower. That will delay the construction sooner or later, but I don't need
it to continue now...

Yeah, and if I ever get it to fly, it *just* might fit in the car in one piece, making it a very convenient grab-and-go-flying model.

I've also been looking at the programming. There will be independent
control over each elevator, each aileron, and the rudder. I'll be able to
do some interesting mixes.

:-/ I removed a servo from the remains of the Seabee wing and the guts are pretty smashed up. It was a BRAND NEW HS-311 servo, too. I will pop it
open and see if it is just the gears, and if so... Hello! They use the
same gears as the HS-300! Don't I have a set of HS-300 gears somewhere?

I've also got two jittery HS-300's that probably need the pot cleaning, a
job I've never done before. I hope there's nothing wrong with the two
HS-81's I'm planning to put in the wing!

Well, that was pretty painless! I *did* have a set of HS-300 gears and
when I stripped the HS-311 that was all that was broken! Pretty chewed
up, mind you:

http://www.anjo.com/misc/servo.gears.jpg

A number of teeth gone from the lower gear on the part on the left, and a couple missing from the upper gear of the part on the right (as
highlighted by the red marker pen).

And look -- all the teeth recovered and removed from the case before reassembly with the replacement gears. Wait a minute! I found and
removed *nine* teeth! Who sneezed?!??

That's not bad considering the amount of foot-pounds per square inch that plane had to encounter with it's F-A-S-T mid-air encounter and spontaneous
ground interface. :-)

You're right. In fact, given the tiny size of some of those gears (sub- millimeter, even for the largest ones) it's amazing they can work at all.
An HS-311 can habdle up to 51 oz. of torque!

It makes me want to try those new Karbonite gears (with carbon fibre in
them) but a Karbonite gear set costs more than an entire HS-311 servo!
The HS-322HD servo only costs $1 more than a HS-311 but replacement gear
sets are double the HS-311 gear sets, and only two of the gears are
Karbonite. The other two are plain nylon. The ones that are Karbonite
are the ones that always break, but that will just transfer the load to
the other two and *they* will break instead of the traditional ones!

I'll have to stick with the $9 servos that use $3 gears.
