Questions for Jack D. and others on this thread. At the recent Toledo R/C Expo, I purchased an Eagletree Guardian for application in my SMGripen jet. As you may know this jet is a high workload on landings with PIO from the canard. I have tamed this somewhat by reduced throws and CG adjustments but would like to try the Guardian stabilizer also. To Jack with the Rafale; I presume you used the "2nd Elevon Reversed" function to control the canard, true? Also, have you tried the "Derivative Gain" option on the unit for your Rafale? I feel that it would work well especially on the wing elevons for roll stability. Any other recommendations would be most appreciated. Note that I plan to install the Guardian in several sport models before the Gripn to gain familiarity with the unit. Thanks in advance.
