Hi Andy,

Barry over at Kennedy told me the spoiler was split to keep the elevator and rudder in clean air for better control while deployed. Less mixing too.

I'm thinking theres possibly a third benefit.

My understanding is that the one large spoiler on the standard version is so effective at killing lift, most people don't deploy it more than 30 ish degrees.
What if the smaller spoilers could be opened closer to 90 degrees? Might that create more drag helping slow the plane down while not dumping too much lift?

I have a Radian ( changed the prop ) and LOVE it. I keep it in the car and toss it up at every opportunity. Its like my meditation machine. Keeps me sane....

Branwell,

Is this 4 M AVA officially available at Kennedy Composites (or in the USA)? I don't see any link to a 4 m AVA on the KC website.

The " Longhorn" 4 meter first shipment has just arrived and sold out. The next shipment is due in about 40 days.

We hope to get some information up on web site in the next week

Hi,

I got a little time this evening to go over the plane and do the basic airframe assembly.

- Install the boom to the fuse.
Perfect fit. No play at all. Used 400 grit paper to ruff up the surfaces, and a smear of 30 minute epoxy to bond the two components.

- Install the stab.
The mount fit perfectly to the boom. A little 400 grit and wicked in thin CA.

- Installed Rudder.
Everything fit perfectly. Again paper and thin CA.

My impression so far is that this plane is pretty much flawless. The workmanship and finish quality of the parts are just amazing.

Have they strengthened the stab mount, and re-worked the retention mechanism?

(standard AVA uses a short length of threaded rod that is simply molded in to the mount - pulls out easily if retaining screw is over-tightened..)

Hi Andy,

The stab retention screw looks as you describe it.

Installing the spoiler servos are an engineering task and a half!

I come from Giant Scale gas planes. Dealing with the tiny servo arms, linkages and minute spaces in the glider is a definite challenge :-)

Am working out the wiring and receiver install.

Given all the carbon in the rear part of the fuse and wing D-Box sections, I am thinking adding a pair of satellite receivers and wing mounting them in open bays might be a good idea.

To reduce the number of connecters and keep things tidy, I am planning to use an old style computer printer parallel port as a connecter. One mounted in the fuse and one in the wing. What do you think?

See pic.

I guess it depends upon your 2.4 system. I fly my Ava with my Futaba 10C and have just one little Rx near the back of the nose. I have whiskers but the pod is 2.4 friendly.

If it were me...just my opinion of course, I would mount the Rx's in the nose if the pod is 2.4 compatible and simply run a Y harness to the split spoilers.

That is one nice Ava you have!

In my carbon Pulsar 3200, went with a AR9000. I installed two remote rx's in the main wing panel, and installed the main rx in the pod. I replaced the two stock 31mm antennas in the main rx with two 62mm ones made out of white servo wire, and stuck 31mm of it outside the fuse. I tested the reception of this using the data logger on the AR9000, and the main antennas has about the same number of drops as the two remote rx in the wing when doing a range test.

It is 2.4 friendly.

I have a little data logger. Am thinking simple is definitely better, so plan to assemble the plane, and with a single receiver in the fuse, run a range test ( turning the plane on all axes ) and only add a remote if absolutely needed.

Many thanks.
