Mark,
Some leaves are starting to fall.
I put the mix in to all my gliders. The amount you use will depend on radio setup and CG. It kind of works like elevator trim in a full size plane. I set up mid stick throttle for normal comfortable flying. Low throttle stick (just a bit of up elevator) is slowest flight without stalling. Forward stick (a bit of down elevator) is for faster flight, but without tucking. If set up correctly (imho) it's like flying with a throttle. Throttle back to slow down and float or throttle up to move out. It really comes in to it's own in light slope conditions. I also like it for launching. I launch at just below mid stick then about half way up I go to full "throttle)... it almost pushes over to level by itself, and it's easy to get to the throttle stick quickly right after launch. Set the mix up on a switch so you can turn it on and off and give it a try... it's free The mix on mine is almost imperceptible on the ground. It may not work with a truly neutral plane.

Launch technique...
Are most people using the thumb on top grip? What launch angle are you aiming for? My launches are consistent with thumb on bottom, but I'd like a bit more height.

So you are basically using it on the slope, not on the flatland? Sounds kind of like reflex and camber on sailplanes or flaperons.

No wind on the slope so we got the Radian to give the Alula's a lift

It does not appear to be so per his post (#806):

had a great time "maidening" my Alula.. flew real well! One slight problem, I could throw it real high, but it would go into a steep nosedive right after reaching the highest point.. after each nosedive it would recover and fly quite well.. is it nose heavy or the opposite. Any input would be greatly appreciated!

I use it almost every flight on slope or or flat land. I went up to 2% mix today... still dialing everything in. I think it adds quite a bit to the flying experience and makes launches easier/more precise.

You need to push the nose over at the top of your launch. If you don't it will stall and lose altitude exactly as you describe.

Yup, I'm still getting used to this, and getting a good transition from launch to flight is the hardest thing. It's kind of ironic (I find) that the harder you launch, the longer it takes to recover (yourself onto the stick!) and the harder to get that smooth transition to normal flight .

Perhaps try deliberately flattening out sooner than you think she needs, then work it gently later and later until you've just got it right.

There's an awesome video early in this thread of a someone launching with a perfect transition at the top, will see if I can find it!

EDIT: Here it is:

Thank you for posting these videos!! Now let's see how quickly I can get to the controls before the stall! It'll be fun practicing anyway...

Here's some footage from my first flight with my new spycam. Thanks for all the advice, I got one of the "808" model keychain spycams and I'm really pleased with it. I think it comes in at only about 15g without the chain attached and I just taped it to the top of the wing over the CG.

I hope to get out on Peel hill soon with the camera this time and hopefully see if I can get some footage of the seagulls. Last couple of times I've got up on the slope they've appeared from nowhere and soared with me for a while! Hope to maybe get a few shots of the castle from the air too, if I'm lucky!

Here you go, a cheeky lunch-break fly on some scrub land 100 yards from my office.

Flattening it at the highest point worked like a charm!! What an amazing plane! The best lunch break I've had in a long time!
