Mercury jittering

I have installed a mercury srs with futaba sbus in stead of a receiver and 3e which has been working fine, this is in a sports jet, but we are finding when the turbine is on full throttle the rudder elevators and to a less extent the ailerons jump about, its like the gyro is vibrating, but it’s fixed down solid to the radio tray, the gyro has been set up using the flight mode switches and setting manual figures for damping, that all works fine it’s jist this problem with the surfaces when on full throttle, please

Shouldn’t be only purchased a few months ago, do you mean underneath ?

Just been reading through the forum, seems it has been a issue in particular with a v1 chip, how long ago were they in supply ?

Richard there is no dot

So I had two brand new on my shelf, one I bought about 1 year ago from nexus and one more recently from motors and rotors, the original one was going to be used in a jet project that did not happen, so it’s just been installed now, first time test this week, so we need to resolve this problem as it is not working correct, and now is flying season, what should we do

I am surprised you did not recall these as it could have caused a big problem in a jet, we thought the gain was too high as it looked like oscillation of the plane on rudder especially, we kept changing the gain, then we by luck was trying the model on the ground and saw on full throttle the surfaces moved, not good

Hi Richard ok thanks, are the details on your website where to send it ? Ideally need it back by the weekend ? Is that possible ?

Thanks we will get it sent

Hi Richard can you confirm you have the unit back now ? My friend Steve smith sent it as the plane is stored at his house

Hi Richard I tried to call you today a couple of times for a update, but couldn’t get through

Hi Richard thanks for the update, where will they message ? Is there a approx time ? Is it a few days ??

Thanks
