Status: offline 		Maybe I'm thinking out loud here, but why not skip the gyro and simply learn how to fly? That pesky little flippy stick on the left side of the transmitter that makes the rudders and nose wheel move really do work together...if you know how to use them.

Just a thought...

No your correct Iam yet to fly a jet that requires one. So then which planes do you suggest need a gyro to fly then, just curious....

Of course heli fliers are 'girly' that goes without saying

The planes don't need gyros to fly them. They need gyros to keep them rock solid. As I said I haven't found the need yet so I wouldn't know until I flew one. But if I was in competition and gyros were allowed, I would be at a disadvantage not using them. No one judges my wings or tail wagging in 15 mph winds so I'm not woried about it.

If you look at this video you can see my Swallow flying with gyro on ailerons. The only time that there is any waggling of the wings is when Dave was trying to free the nose leg for landing. The rest of the time it is smooth as silk. ..........................



Jgwright
The Swallow is in my opinion a nice plane May I ask where you got the kit or planes for it ? I have tried to find planes for it but so far no luck.

Sorry for off-topic.

Status: offline 		Gyro or not ?

When I started flying helis way back, there were those that said you must learn to fly your heli without gyro --> that way you become a better pilot.

Not so surten that that statement is valid today. Not a helipilot today that would dream of flying without a headlock-gyro. And flying has become much more advanced as a benefit of the gyro.

So if it help groundhandeling and stability in air, use them

not best english, but hope you get it

I installed the Gyro for my F-16 tailon (Futaba GYA 352 Bi-axial Gyro) due to fly more scale and smoothly.I believe the Gyro save my F-16!I heard that the Gyro save another 1/6 F-16 even its whole fin lost months ago.

Status: offline 		Good to hear that your F-16 is safe and sound and looking closely on the picture you can actually see the rudder is brooken off in the top hinge. It also seems that the elevons are working "hard" to stabilize the plane --> right half is pointing up and left is pointing down.

The Swallow started as a Mick Reeves Venom and I cut the rear off and grafted the correct angle tail on with a fin and reformed the wing roots to match the new wings I made. It was described in RCJI magazine, it is one of the nicest flying planes I have owned.

I was teaching a beginner who was very rough with the sticks so I told him to treat them gently like a woman's nipples.

The guy flying next to us then did a low pass with the stick between his teeth making growling sounds - you had to be there. - John.

Wow dave, this is interesteing coming from a pilot who flies a ARF Boomerang!!! the easiest jet in the world to fly!!! I would hope that you didn't need a gyro , however i do remember having to land your plane for you cause you couldn't..............

Mate i sudguest you keep your comments like that to yourself when you have very experience model jet pilots who fly some of the hardest to fly aircraft in the world in this thread , and im not talking about me incase you think im being cocky. When you get past your boomerang that can land slower then a 40 size trainer and flies faster then the takeoff speed of my falcon and has a wing loading higher then a sport pattern plane ill start to listen...


As for a well set up model .... i fairly remember that you have massive thrust issues with a model that pitches violently on power application... mayby a bit of thrust re-alignment might be needed. after all , A well set up plane makes all the differnce remember did you replace that stripped gear servo yet????


Happy Landings everyone!

Status: offline 		Some of the comment on this thread are absolute hogwash, sorry but its true, davo058 wins the prize, hands down ! !

Swept wing jets almost ALWAYS have an interraction between directional and lateral stability, in real jets this can lead to serious, often divergent, dutch rolling unless a yaw damper is engaged, some use two or even three dampers. (VC10) Its the very nature of swept wings and the greater the sweep the greater the effect (in general)

In smooth air MOST jets are super smooth, early Bobcats with gear extended an exception, easily fixed with a rudder gyro. In any turbulence, rough air, any yaw oscillation can rapidly lead to roll oscillations and on it goes. Easy fix is to add a gyro on the yaw axis (makes the take-off and landing rolls straighter, too) and even further smoothness is added by a gyro on the roll axis as shown by Jeremy Macmillan flying his Hunter at Cottesmore which was silky smooth even in the turbulence. It looked exactly like a REAL Hunter , absolutely solid.

Anyone who thinks they can smooth out any yaw/roll coupling in any even the mildest of turbulence by the use of expo, smoother control movements etc., is living in a fantasy world. ! Most of my jets have a yaw damper, inc nosewheel steering, and are now being further enhanced by a roll damper too, my Bobcats are now as smooth in rough air as they are in smooth. (Futaba GYA351 dual channel gyros)

If you arent sure about gyros, try fitting one to YOUR model and seeing the efffect, different aircraft react in differnt ways, but ALL will be smoother to a greater or lesser degree. Dependswhat you are trying to achieve.

Regards, David Gladwin.
