"This is valid when you use FrSky's ACCST system like D8R-XP and also noted in the manual for the D8R-XP receivers. When using the FrSky's FASST receivers like TFR4 you may use all 8 channels without any problems. I have both and was…"

"Hi Steven! Thank you very  much for you efforts, logging and longtime efforts in solving this twitching issue! I hope the developers (if they still read this thread) can drop a little message in this thread when the new PPM firmware is ready…"

"I have twitches on the R6014HS which is no sbus..... :-( Arild"

"No need for opening your brand new T8FG :-) I thought of making an arrangement which you only plug the FrSky module into the trainerport on the back. This would automaticly disable the internal FASST module. Opening my T8FG was a good thing as the…"

"Hi It seems the twitching for Futaba radios have been elevated by the developers - great and thanks! I only have the twitching in the air - which has been some expensive and the winter in Norway will give me slow testing speed if I should…"

"Hi again, I am sorry I have no logs, but so I wish I had..... It is to cold for me to go outside right now, but I just had to try a small lift inside... The quad I had problems with is the old APM1.4 1280 chip, so no logs on that one. So I put my…"

"You do not set any "framerate". In the LNK-Frequency menu you choose FASST betweeen MLT/MLT2/7ch. It is also noted on the main-screen under the timer ST2 where you read MLT/MLT2 or 7ch. MLT2 I think is for the R6014FS/HS and the MLT is…"

"hi, sorry I have no logs. This was an APM…"

"Hi Steve, Did you see my post here in this thread http://diydrones.com/xn/detail/705844:Comment:1023183 ? Also follow the thread linked to  in my post. My Quad also spiked /twitched using Futaba T8FG & R6014HS... You have done a lot of…"

"I did radio calibration many times before I the rx change, and first thing after. The values in the radio calibration page in the MP was solid - at least on the bench without power to the motors. There was something happening when vibrations and…"

"Hi, there are many good tips here, but have a look here: http://diydrones.com/forum/topics/crash-and-freeze?xg_source=msg_com_forum&id=705844%3ATopic%3A739002&page=5#comments The initial problem for the thread was that the quad flipped over…"

"Hi - I know the thread i old, but I thought I cold give a final note on what the problem was. I am sorry I did not write this earlier but I saw some posts about twitching in another thread and so I remembered to update this old thread. By powering…"

"@Jahn Otto I am still wondering why this APM needs a second battery while others can run from the BEC in one of the ESCs.... Did the quad flip over surprisingly when it was new, or was this behavior something that developed over time? Arild"

"I know ;-)"

"There was one other thing I forgot to mention in my update.... I do not know if it matters. But I discovered that one of the components on the GPS-adapter was missing. So I removed the GPS before the indoor session yesterday. New adapter-board is…"

"No, I have to use a BEC, because if I use one of the BEC in one of the ESC, I power the APM from the same battery as the motors. I wanted to power the motors and the APM from two separate batteries. ....hmmmm..... I am not sure you want it back…"
