Hey there fly mates, i have up & down shaking in my heli that just recently started. I have a Spektrum Dx6i TX with Ar7200BX RX and before i adjust anything i would like to ask for help. My heli been flying great for the longest time till yesterday when she developed an up & down movement. Not to bad but enough to make me wonder. My question is what should i adjust first? The Rx or TX and i heard that it might be the tail servo going bad so I'm confused and my user guide for the RX doesn't have information on up & down shaking just tail dynamic. Any information would be helpful

You didn't say what heli your flying but here are a couple things. Bent feathering shaft? Or FLybar is bent? Check your blade tracking. Bend Blade Holder. Something sounds out of whack. Did you have a crash prior to this starting? If not maybe something has worked its way loose. Check all screws and bolts.

Good Luck

If you have not crashed and nothing has changed i can only think of one thing; maintenance the head block. New dampeners and possibly bearings. I am leaning on dampeners.

Some tail issues can lead to this issue, but if you say its been flying well for the longest then i think its a maintenance issue. Why because one may not do a tear down unless they crash. Dampeners are cheap, relatively speaking and easy to replace. Personally i would try that before tuning your beastx. That gyro normally is a set and forget unit.

Thank you. Sorry about not stating that the heli is a Tarot 450 pro DFC and thanks for jogging my memory. I just remember that i did have slight bend in the feathering shaft and didn't replace it when i was changing other parts. My fault for not slowing down when going through the check list after crash. I notice it after going through the list AGAIN! I guess i wanted to fly before the heli was ready.

Yeah I know that feeling. Had a bent FLybar on my V912 from a minor altercation with a bird feeder, put it away and forgot I had bent it and instead of replacing/straightening it I just went flying. It wasn't terrible but bad enough that the video I recorded with the under bird camera was completely fuzzy.

Glad you figured it out.

Well i guess that shot my prognosis all to heck, lol. Yeah forgetting to tell us about a crash changes the prognosis. Glad i prefaced with if you hand not crashed.

Glad thou got it sorted.

I'm a professional crasher, so I think of things from that standpoint. LOL. Makes those crashless flights so much more enjoyable and memorable though .

I would be too if i wasnt so scared to crash. If i had a job to support it i would be crashing all the time.
