Point taken Harry but old habits die hard.

Picture the scene, flying from a runway intersection. Model on finals, nose well up and positive rate of decent. As it gets near me I notice out the corner of my eye that the track will take it into the grass verge on the other side of the intersection so I squeeze the rudder stick and it rolls just about as rapidly as on aileron and I'm forced to roll upright and land it where ever it wants to go. This cost me a bent nosegear pin and a lost door so I won't be doing that again. I know I should have considered an overshoot but as a novice jet pilot I wasn't sure I could have the motor spool up in time.

Hopefully my new L39 will have better handling characteristics although I'm told that these need rudder gyros too!

Alright guys, I installed the G770 Gyro on the Cougar. I put the Gyro on the Rudder servo and the gain on Aux 5 (rotary knob on 12X radio). Everything is working lovely. I can increase and decrease the gain fantastically. I did not set it up for heading hold. The question I have is the following: Can I install the gyro right over the receiver? In other words, for clearance purposes, in my cougar, the only place for the gyro is right over the receiver (2.4 R221). I can install it over the main fuel tank, but that would require extensions and I would prefer not to use them. I range checked it with my brother and everything seemed to work just fine moving the nose left and right with the gyro compensating. Flight test on Tuesday.

Should be OK, in heli's we end up with them together too.

Thanks Dave. I will report on how the cougar flies with the gyro on Tuesday. Alex.

The weather did not cooperate last Tuesday, but today was perfect. Went the to field. I was a bit apprehensive at first, never have flown with a gyro. I had this felling that the gyro would take over my controls and carry my plane away forever. LOL. The roll out was percect and as soon as the jet rotated, I knew the gyro was working. The Cougar did not wiggle at all with the gyro on the rudder. It flew straigt as an arrow with absolutely no dutch roll. I thought that I would feel the gyro working against me, but It was fine. I had the gyro gain set on a rotary knob just in case I needed to deactivate it in a hurry. My initial setting seemed appropriate. Thanks you guys for your help. Alex.

Stumbled across [link=http://www.bobjellison.com/f9f_6_3.htm]this link[/link], which contained the following paragraph regarding the development of the Cougar variant of the Panther, confirming that it's a yaw issue and not a roll issue. IMO those seeking to fix the problem with roll gyros are addressing the symptom rather than the disease.......
