Still I've had good experience with my Beast 3D and Hyper Taxi so can't loose faith at this early stage

I wonder will the gain be sufficient to hold a hover hands off?
I know the mechanical setup of the plane has to be condusive but just wondering..
Quandry,

I think that would require a heading-hold mode. As set up on the UMX planes, AS3X operates in rate mode.

On their Blade series helis they achieve Heading Hold with AS3X so it seems to be capable. That's why I was wondering if maybe a high gain will give heading hold, could be interesting.

The Spektrum website says the receiver is suitable for '90-size electric airplanes (not designed for nitro or gas aircraft)'.
I haven't got a clue what 90 size means. Would someone enlighten me, please?

90 size means an airplane with a 90 size motor like E flite's Power 90 http://www.e-fliterc.com/Products/De...odID=EFLM4090A

The Power 90 is rated for sport/scale planes 8-13 lbs or 3D planes up to 10 lbs.

Expanding a bit on Mugen's post...

For a number of decades, recommended 2-stroke glow-engine displacement was the standard measurement of RC plane sizes. For instance, a '40-size' plane typically requires a .40-.46 cubic-inch two-stroke glow engine, and AUW is usually around 4-5 pounds for a purpose-built aerobatic model.

Larger electrics adopted the same nomenclature, as it simplified the electric conversion process. So, '90-size electric' is a reference to ICE power, in which the plane would require an electric motor with power similar to a .90 cubic-inch 2-stroke glow engine.

Mugen4Lfe and turboparker, thank you, that's very helpful.
90 is much more than adequate for the planes I fly.
I like AS3X, so I'll definitely give this receiver a try.

A Eagletree Guardian is a better system with 2D and 3D modes if you have the space to fit it in your plane. Price for the Guardian is about $75 shipped plus your receiver.

Having never used an Eagletree Guardian myself, what makes it better?

It has both a 3 axis gyro that can be programmed to have heading hold or simple rate mode. In addition, it has 3 accelerometers (2 D) that will right the plane to level flight if you release the sticks. Pretty amazing. I have 6 of them and fly a 17 ounce foam delta in 25 mph winds (flag sticking straight out). Other planes are grounded and I am flying.

Another huge difference between the two - the AR635 can't be used in any ICE-powered planes. There is a big caution about using it only in electrics, and then only in 90-size and smaller electrics. In contrast, the Guardian can be used in 200 MPH turbines & giant-scale gassers.

Also, the Guardian has automatic gain-induced oscillation detection & auto gain reduction, and you can freely adjust the master gain from your tx. Both are extremely important features for fast planes with wide speed envelopes.

Joel,

And the the list goes on and on about the features and functions of the Guardian.

So are analog servos a no-no with this receiver?

It depends on whether you choose to listen to the manual, or the "experts" in this thread.

90 size and 17oz planes, not to mention a 13gr rcvr I thought this was a micro forum???

This may be a micro forum, but the product is clearly being marketed for use in planes that are way larger than micro-size. In fact, the specs say that it's intended for electrics up to 90-size. The smallest plane in which HH currently uses this rx is the Vision Aire - a 2.75-pound, 3s 2200-powered, 10-size 3D plane. It is also used in the Carbon-Z Splendor - a 5.5-pound, 6s 3200-powered, 50-size pattern ship.
