Hi all, just upgraded from a Walkera coaxial helicopter (Lama 400D) to the Blade 200s FP.
I had no problem getting it to hover soon after removing it from the box and charging the battery.
One question, the heli wobbles.
Is this normal for a FP flybarless helicopter?
I am only used to the coaxial and it didn't wobble at all.
The Walkera is also much bigger not sure if this has anything to do with it.

Any advice appreciated

Cheers
Rob

Hi Dorisrob, when you say Wobble is the side to side up and down or otherwise?
Start by making sure that.
1. the blades are balanced.
2. the main shaft or feathering shafts are not bent.

And if possible attach a video of it flying.

Hi Admiral,
After watching some youtube videos, it looks like fairly normal behaviour. It twitches a little, but seems to fly ok.
I'm only a begginer, just hovering it around at the moment.
Thanks
Rob

Hi Rob and welcome to the forum from Wales UK.

Good advice from Keith, no-matter what size a heli is, if it wobbles something is amiss and generating a frequency. If the wobble is a repeated movement at the same point of rotation on either the main or tail rotor, then that back and forth movement will damage the bearing races on one or more of the bearings. If the action continues there will eventually be one or more notchy bearings. RC helicopters are a collection of random frequencies held in orchestrion by thread-loc. So reducing the amplitude of any and all frequencies will prolong the life of the bearings Wink
