Here is the AR6410L (DSMX version of AR6400L)

I guess the AR6400L is discontinued.

But only because they replaced it with a DSMX version, which does the EXACT same thing, but DSMX compatible! But either one, they do the exact same thing!

So, yeah, I guess they did, but other places still sell the old version as well!

If that is really the case ( have not checked myself):

I was talking with a flyer that appeared to be a Horizon "insider" at the Holiday Electric Fly last December, among other things, he told me that Horizon was moving away from the "bricks" and toward separate components to save on warranty claims. Example: having to replace an entire brick when a single servo went south.

EDIT: DSMX versions are good news. But the raft of AR6400L bricks I have were made of gold for a minute or two there

Hi Richard,

Glad they are of use to you.. The model is a bit over designed..

I used 1/32" balsa for the rear top and bottom sheeting, 1/8" light ply for F1. Forget about F1a and F2a. F5 can just be the lower half for the bottom sheeting support.
I also just used med 1/16" balsa for the bottom sheeting instead of ply and no u/c..

I glued the top wing in position as this stiffens up the whole structure.

With your motor, I would suggest putting the esc in the nose, the servo behind F3. Also my AR6300 RX sits there and the LiPo sits between F2 and F3.. It balances fine with the gear distributed like that.

I tissued and doped mine... 2 spray coats of sanding sealer and then stuck the tissue down with spray dope followed by a second coat.

One more in the swarm I'm looking forward to the pics

Cheers,

Shaun

Hard to believe they flew that at 4 oz., but with at TD .010 it probably really
zipped.
I have a Jr. Falcon that I did the same thing, even painted it just like the pic
on the box.
Will post pix when it is done.

I agree. Minimum formers. I also will glue on the top wing and use rubber bands on the bottom to allow access. Battery will probably go behind the motor, depending on CG,
although I lengthened the nose slightly. Will use CF rod for the torque rod, with the servo mounted sideways to provide the twist.
I will just use couple of coats of clear dope and some tape for decoration, and print out
a decal for the "GNAT".
Do you have the original construction article? Even after almost 50 years, I remember a quote when the pilot told his launcher to just "Chuck it like a dart".

you do know you can replace the servos with out
buying a new brick, right? You just need a REALLY tiny screwdriver and to be REALLY good at soldering.

I mean, why would they sell this:? http://www.horizonhobby.com/products...-throw-SPM6832

Sorry, I only have the plan. I would like to see the article if anybody could scan it .

2mm carbon tube works really well for torque rods,with the advantage that you can cyno music wire in the end for the crank.

If you look on our site www.singlechannel.co.uk you can see a number of s/c models converted using a servo like you mentioned...

There are also a number of s/c tx's converted to 2.4g for the real s/c experience.

Hi Richard,
No test flight yet... the weather has been vile in the UK...
wind & rain.
Good luck with yours.. looks good...
I would set low rates on the rudder.... These tiddlers tend to be very sensitive.

I may make the Ken Willard Pageboy next . It's a bit big at 15" span though

Cheers,
Shaun

I taped a penny to the rear to get the CG per the plans. On the first launch, it pitched up
badly, so I removed the penny. It flew nose up, but reducing the throttle helped.
It apparently needs more down thrust. I had considerably less than that shown on the
plans. No damage. The 10 gram motor has lots of power. May reduce the prop
size, currently 5 x 4.3.
Thanks again for the plans.
Do you have the pageboy plans?

If the servo motor is still fuctioning, you can press the motor out of the old rack and press it into the new rack and no solder is required.

To replace the racks, you need a #000 Phillips screw driver.
