Status: offline 		I am starting a scratch built 74" Twin Comanche and I'am considering putting in a single or possibly a two axis gryo two help keep the plane upright and and pointy end forward in case of a flame out. I'm sure it would be faster than me in countering the yaw.

Anybody have any recommendations on gyros or thoughts on using them in a twin?

Status: offline 		The P-61 I assembled had 2 gyro's, the internal Weatronics gyro was hooked to the ailerons, and a GY401 on the rudders, for just the reason you described.
For the very short time it flew, it was like on rails. All I had to do was tell it what direction changes I wanted then let go.
I had previously put a gyro on the ailerons of a TF Corsair and it made such a difference to it's handling, especially landing, where all I had to do was set the throttle, line it up on the strip and then I had time to juggle the gear, flaps, etc without having a hand tied to the aileron stick.

I read quite a few articles in setting up a twin and the addition of a gyro was the definitive factor in preventing the spiral of death. One tester even managed to take off on one engine with a gyro installed, very carefully mind you, but he did manage it.

Try it, you won't be disappointed.

Now what about on 4 engined model with three fins and 5 rudders at the back, would you need gyros on this type of model? (Super Constellation)

Status: offline 		I have to admit I am now biased towards gyro use on major control surfaces (not sure about elevator, but I haven't tried that yet).

On any big bird where you are juggling flaps, retracts, and throttle on a decent for landing it really pays dividends not to be juggling the ailerons as well.

On multi engine jobs I am now sold on the safety when an engine outs on you, "has one of those engines stopped???" and the tracking on take off is just great, lift off, wheels up, flaps up, guess I better tell it to change direction

For an expensive model the cost is really minimal.

I was using a Weatronics so I could control up to eight servo's with the one gyro.

For a project like that Constellation I wouldn't think twice about using them.

Status: offline 		Kwell, I love Connies. Post pics as you go. How big? Engines? Of course you are doing it in the Navy WC-121 Hurricane Hunter scheme?


mbol, you mentioned the P-61 had a short flying time. What happened to it?

Thanks for the advice all,
Rick
