How stable in hover should Beastx be?

[Gazzer1uk]

Me again.......

So having got the Trex700E off the ground, the tracking is pretty spot on, I've got too much neg pitch for my skill level so will adjust, but I wondered just how stable the beastx keeps things in a hover?

I noticed that on stick release I got a slight nose up and backward flight, so could not go sticks off for long. I was in the back garden, bit of a wind but this seemed to me like a consistent behaviour.

So... should I change anything mechanically I am thinking swashplate linkage, or anything electronically, or indeed anything else?

Cheers,

Check your COG and also your trims have not been knocked off centre. Beast x will see any trim as a command

What Don said! Also - have you levelled your swashplate (throughout the collective range) using a swash leveller ??

Hi,

Trim is OK CofG.... hmmmm best check that!

I probably ought redo the swashplate levelling.... I have a leveller somewhere, was done by eyeball this time as previously had been set up, but worth checking as you guys suggest,

So would I be right in thinking, it should be pretty "hands off" stable in a hover?

Cheers,

As a reference, you should be able to hold a hands off hover on a 700 with no wind for a few seconds before having to put any decent corrective input.

The heli will float off in a direction, (usually left because the tail rotor is generating thrust with nothing to counter it) it shouldn't start to progressively tilt, that's a sign of vibration. I had this symptom on my BeastX on my 550 at a certain headspeed, the resonant frequency at that RPM upset the BeastX.

So.........

i redid did swash levelling and got it true. A few flights and it was really stable and comfortable. I was going to ask next about the pitch settings but had worked out the excessive negative pitch could be controlled by the pitch curve, limiting negative pitch. Shame I did not manage putting this on all the flight modes so when I went from the limited neg pitch on norm and st1 accidentally into st2, I wouldn't suddenly have gone from -2 to -7........ I nearly caught it, nearly! Rather expensive repair coming up! Thanks for the help, pretty sure I will be back for more later! Gaz

All back up and running fabulously, actually had a flight at the field, not brave enough for too many circuits but hands off for about 4 seconds and she just sat there!!!

Wish i had a back garden big enough for a 700

be safe

[Gazzer1uk]

It's about 100 x 80 feet about the same size as the clubs take off and landing patch, though I have trees and fences protecting an escaping heli, whereas the club field has more fields around!

Seriously, low hovering is not a problem, I can have quite a distance between me and the model, safety is a practiced procedure in my life.
