Beast X 7200 DR/Expo
I just bought a Blade 360 cfx with the Beast X 7200. I set up DR/Expo in the Tx (New DX9) for soft response but the settings had no effect. I lifted off in full 3d and promptly destroyed the heli.
What am I missing here. Do I have to set up DR/Expo in the Beast X?

What TX settings did you use...and did you go through the entire AR7200BX menu's ?

Make sure parameter B (flashing amber LED) has a solid blue status light, this is radio dr/expo control, any other color are preset configurations and those combined with radio expo/dr can be bad.

I believe the DR/Expo was preset at 100 for aileron, elevator and rudder. I changed them all to 50/20.

I'll give that a shot.

Might not be a bad idea to check all the menu settings

50/20?!?! I wonder if your control is too slow. Might want to go back to 90-100/20. Nothing wrong with 20 expo but 50 d/r is dang rare, if parameter B is solid blue (transmitter) then your rotation rates will be slow and perhaps be behind your controls making it feel very sluggish and uncontrollable, depending on your skill, machine and other setup, of course.

Of course the Heli is still going to haul ass due to its headspeed, he was referring to the roll rates, let's say the Heli is drifting to the left, with your d/r at 50 the Heli may still keep drifting left when you give it right ail resulting in your crash, a very docile setting is usually 80/20, at most 75/25! So to put it plainly, you most likely set your d/r way too low at 50 which resulted in your crash!

I just read this thread and it answered my question. I needed to soften up my controls. TY this is the best place to find answers!!!!!!

The problem was whenever I made an input the heli went hard over. It was extremely sensitive. The blades got perpendicular to the ground a number of times before I crashed. The DR/Expo in the Tx were not functioning.

I see, well there must have been some mistake, I also have a 360CFX and set it up the same way by downloading the model on the spektrum site! Did you change anything in the Beast settings?

Perhaps your gyro compensations were reversed... If so then the BX gyro would augment your inputs instead of stabilizing them, and - speaking from personal experience here - the heli will be so sensitive as to be unflyable beyond a few seconds - if that.
It's unlikely that a 360 would come out of the box with incorrect gyro settings, but it's one thing to check based on your description above.

My main thoughts were that it likely can't be a DR/Expo issue, though such high values can make them feel so mushy as to be horrbile to fly, but not so horrible as to be impossible to fly, even on really big values. I also concluded that it couldn't be an issue with mixing the DR/Expo with built in settings on some of the canned or stock modes, because those would only become an issue for when attempting accurate control of high rates. Near centre, trying to maintain a hover, everything is low and slow, and they would play nicely enough together, plus the default would more than likely be set it to Tx mode anyway. Then we read that the heli, prior to going in, was going from 90 degrees left to 90 degrees right, and at that point I came to the same conclusion as you, that this sounds like the direction of correction is incorrect, and probably only on aileron. Not even sure how you can get them in the air in this state, but I figured if you pop it up quickly enough, and have good reactions to cyclic, and if the gain is lowish, it might be possible. All the time it had been plaguing me that it might be this, but that last bit about going from one side to the other convinced me. It will likely only be wrong on aileron, hence why the only difficulty was in this plane, with no description of an elevator or tail issue. Not only that, with 50% dual rates, you'd be hard pushed to even get it over to 90 degrees, you'd have to wait a few seconds whilst it slowly rolled there, lol, let alone have it boinging from one side to the other in an instant. The only other thing that occurred to me is that it might be a totally incorrect setting at step J, which would give default built in resolution, travel and gain issues way beyond what it is expecting or what might be able to be controlled. If it is a reverse setting on cyclic aileron correction, big props to you for having managed to nearly control it.

Agreed, Sutty. I contemplated my answer, too, but having personally got my elevator comp wrong once (!), I know exactly what it does, and it's as he described... 90 degrees one way, then the other. I was lucky... Skids and blades ($150).
Again, I don't see how an OEM product could have this setting wrong put of the box, but if the OP entered the menu and accidentally changed it, then it's a possibility either way and should be checked. Low rates and endpoints won't make it do that... It'll just be slow as molasses in January. OP - I'd be happy to Skype and assist you if you'd like; PM if so.

So I'm assuming that this heli came set up right out the box? Hate to hear you had this bad experience. I hope you don't abandon the beastx product line. I've had several different FBL controllers and none of the were as good as these. My advice is ditch the ARF and build you a nice kit. Chase 360 lol

This might be a silly question, but do you have the BeastX in "transmitter mode" in the parameter menu? If you have it on any of the preset settings...Default is "Sport" , then pro and so on, you don't use ANY expo or DR in the transmitter. It's parameter B...
B. Control Behavior Menu point (B) allows you to select between different control behaviors for your helicopter, including the maximum rotation rate and exponential. Factory setting is “Sport”, which should be suitable for most pilots. “Normal” has a decreased rotation rate for cyclic and tail controls, as well as increased exponential. When you are comfortable flying in “Normal”, find your personal preference by increasing the Control Behavior one option at a time. Purple Solid Normal Red Flashing Sport* Red Solid Pro Blue Flashing Extreme Blue Solid Transmitter If you select one of the preset Control Behaviors, do not use Exponential and/or Dual Rates in your transmitter. Press the setup button once to move to Parameter menu point (C). |
