IDIOTS GUIDE NEEDED AR7200bx

[dogbiscuit]

That is great waveydavey thankyou. Will get on to a full setup tomorrow excited to see if flybarless is everything it's built up to be!

you wont be disapointed..... It is !

[trillian]

I do remember my frustration with the Beast X when I first got it but that was mainly because I wasn't holding the button down long enough to get it to go into the parameter menu! The whole flybarless thing can seem like another language at first but it starts to become logical after a while (either that or I have become Spock)

Helis and RC in general is not easy. If you follow instructions it usually works. Not many people do and then get problems. It does seem easy after a while, but you can still have problems if something is faulty or you can read something and misinterpret it or just get it wrong. Even experienced people get things wrong from time to time. Sometimes you can check things over and over and miss something that is obvious to someone else. Servo testers can be bought for a few pounds, or a cheap rx.

so an update on the situation. Set it up and managed to get it working. however when i began to spool up for test flight, just as it begins to lift off it starts bouncing up and down. Here is the video to show what its doing but im stumped. Your thoughts would be useful once again haha AR7200BX on T-Rex 450 pro problem. HELP! please share your comments on possible reasons for this. - YouTube

cheers ladies and gents !

My guess would be the swash gain needs to come down. It's like the equivalent of a fast tail wag when the gain is too high.

I have never had that happen myself. Did you change the position of one of the three pots? My thought would be try turning down pot 1 slightly (and this is assuming it is starting from the default position which is 12 o-clock). All three pots should be at 12 and they are extremely sensitive, so only a tiny movement can make a huge difference.

[GIXERMAN]

Proberly vibration, try with main and tails off, and see what swash is doing. Simulate a flight on floor

[Clayts]

I have a new dilemma for you gentleman.

I set up my AR7200BX and have flown it since setup.

I have since not flown it for about a week and today when I attached the battery it wasn't set up at all and was doing its own movements when I moved the sticks.

After spending a while going through set up again finally It was working so I took it for a flight but.... Each time I begin to put power on, fast or slow , the tail spins to the right. It's not a rough movement and it is smooth but I can't get my head round what would make the tail spin right on acceleration.


I have checked for vibes and nothing there so any ideas? I'm sure it's something probably really easy!

Cheers

Sounds like you've got it in rate mode on the tail, when the unit is powered and initialised what colour is the led, if purple then you've got something wrong on the gain setup in the Tx, if it's blue the it's in HH

Did you sort the bobbing up and down, if not then a thought might be that the mounting of the unit is too soft, also the downwash in such a confined space isn't going to help

[Clayts]

It's solid blue is its in HH mode. And yeah the bobbing I think was a combination of vibes from tail boom and the gain being set to high so I turned down the swash plate gain. But this doesn't make sense to me why it would move the tail on throttling up.

It was outside today so had a good fly around with it to test it but whenever adding power I had to courted act the tail moving round.

[brummycraig]

Can we assume you have the 3 pots set to 12 o'clock as per the factory setting and that you have a rough gyro gain dialed in your tx? around 40% a good place to start so once initialized the unit should show a blue status LED (Heading hold mode) and F or G lit?

[Clayts]

So on my TX I should change the tail gain to about 40 ? I thought that may put the unit into rate mode? :s

[waveydavey]

No it won't, what Tx is it and whre are you with the gain as it is now. Have you watched the flight tuning videos on youtube, done by BeastX when they first released it

[brummycraig]

I'm using a dx7s and have 45% in gyro menu, this gives me a blue led (HH) and the letter G lights initially or when i toggle between HH and rate (I have Rate set to -40% but dont ever fly in rate)

If you have a dx6i i believe its different, maybe others can suggest the numbers? again other radios I have no idea.

[Mutley2]

Stick with it fella, just started on mine for the first time and had to walk away and have a good think. It helps loads, clears the grey cells and start a fresh...
