sorry im late guys been busy building.

phoenix autos arent right if you try to come down too quickly as richie said we are looking at this issue for 1.04. in the mean time tune the blade inertia to match your own model/blades so that when you flick hold from the hover it holds for a similar amount of time.

once you got the hang of autos on the sim and you can get them down infront of you 100% of the time then head down to the field.

hover the model infront of yourself at about 4ft then hit hold.

it will probably fly for about 5secs before you run out of headspeed and have to land.

increase the throttle hold value to give an artificially high idle. by trial and error set the value to give you about 20secs of hang time when you hit the hold in the hover.

no go off and do some powered descents... so basically an approach as if you are autoing but under power. aim for the spot directly infront of you where you took off from obviously do it into wind.

once you can do them reliably, hit throttle hold.

it will not be a drama as you have plenty of hang time to play with.

over the next few flights slowly reduce the throttle hold value into the tx until your almost back at idle.

autos are great fun i do atleast 2 per flight normally.

"autos are great fun i do atleast 2 per flight normally."

and very nice too Ade,,

remember us mere mortals have to pay for any damage which can be a slight deterrent!!

don't damage it then

Easy for you to say!!

Thanks for the note about winding up the t-hold to keep a minimum rotor rpm on first autos. Hadn't thought of that.

Can I take it from the earlier blade discussion that my 600mm BBT white blades (not maniacs) are close to the ideal for trying first autos with?

I've been baby autoing from head height, and also running out the tank in the hover and practising to see how much spin there is in the rotor.

Can I take it that the fact the motor speeds up quite a lot when it runs dry as assurance that it is still comfortably rich at hovering throttle?

I think 3DBasher said there's not a lot in it between the Mainacs and the normal BBT's down at the site he tryed both on the T-rex 600.

HighlanderJC's T-rex 600 autos fine on the normal BBT's and it weight's the same as my Raptor Titan.

Are your blades the TT blades that BBT make? (the ones that used to be badged as Thunder Tigers) If so think they are excellent on the autos. I was using NHPs which aren't anywhere near as good.

All I would say to this is I wouldn't run out of fuel on purpose. If you are hovering and running the engine is doing 15000-17000 rpm, running out of fuel is effectively leaning the engine out at high speed. It can't be good for it. Plus I speak as someone who knows (changed 6 sets of enigine bearings since I started in Jan! ).

Full autos are incredibly addictive and for me they sum up what heli flying is really about. They are fun and incredibly satisfying and inprove your flying IMHO.

I just ran it dry in the hover at the end of the last flying session to practice a "unexpected" engine cut (at least one I didn't induce). I could still hold my finger on the back plate indefinitely, barely warm to the touch, so not a very long lean run!
I can't be sure of the identification of the blades. The seller didn't really know if they were glass or carbon (!), they are white but show black underneath at a few places. They appear to be BBT from the shape of the root reinforcement and tip shape. And they spin on and on - quite a long hang to the hover after cutting the engine.
They seem very heavy - but I'm a trex450 pilot, of course they are heavy compared to radix315!
