Hover radius

[Opie420]

I am new to the rc helicopter world, I have a helimax axe cx micro. I have only been flying it a couple days with some wrecks already of course. I was wondering what the hover radius is for this helo inside with no wind and how high in the air? I usually fly in the garage with the cars out so it is a 2 car garage so I try to work on the trim to make a good hover but I spend more time working on hitting the ceiling, walls, or ground. Also, is it normal to have to work the trim every time you fly or should you be able to put the trim in one setting and leave there every flight?

Not sure what you mean by hover radius - you should be able to keep it within about the distance of the rotor blades. In terms of radio range, it should literally be half a mile or more - maybe not on the micro, but it's ridiculous to fly that far away. Trimming a helicopter is best done with mechanical adjustments, but with the little coaxials it's easier to just use the trim levers, and it won't mess it up to do that, unless you get all the way off center. Coaxials with two motors commonly lose rudder trim during flight as the motors heat up unevenly - eventually the gyro can not compensate for this any more, and you may need to use trim on the rudder channel. The cyclic trim should be set to one spot and left there.

There is some information about it here:

That heli needs minor trim adjustments as the battery loses power. If it consistently rotates in the same direction you need to adjust the proportional pot. Also, on this heli I found it seems to work better with the gain set low.

What i mean by hover radius is if I was to let go of the controls on a good hover how much should it move. I understand that sitting in one spot by itself won't happen but moves around a little. I hope that helped on what i meant.

It depends on how long you let go for. If it's more than 3 seconds, you are going to be picking up pieces. The Axe CX can move around a lot and it's highly affected by air currents.

LOL, I dont' have to let go to have to pick up pieces. That is what I wanted to know. Thank you

Check the Axe CX topics in the multi-rotor heli forum for common problems and fixes. It's not the most durable heli.

Golden rule of helicopter fllying... never take your hands off the control levers. :) :)

Hands-off hover is only possible for a few seconds, indoors in a BIG space. Longest I've ever had without electronic assistance is 4 seconds (with a PERFECTLY trimmed metal-head Mini-Titan). Of course, I have this flybarless 4-blade scale T-Rex which you can park and forget, it's so stable in the hover... but that has $300 worth of cyclic gyro locking it down... and even then it's a total handful once you start moving.

lol not entirely true. I had one of those Hirobo llamas. The co-axial heli with foam blades....I could let go of the controls for 10 seconds...I even counted it...that was an amazing heli.

Hi i have been flying mine perfect it´s very stable i just have been trouble lattley with the rudder i have my trim all the way to the rigth and i still need to put a little extra on the stick, i have checked the gears and the mechanic parts and evething seems to be OK do i need to move the little screws on the reciver or one motor is failing so one spins faster than the other? any help will be great!
thanks

What kind of heli is it?

[vegaslow]

Axe CX micro

A PERFECTLY set up and trimmed co-ax ( with ZERO .. I MEAN ZERO wind ) should ( in theory ) be able to hover hands off cyclic forever.However even in in this theorictial situation , there will ALWAYS be some movement of the heli.

sadly a perfectly set up and trimmed co-ax will never exist.

Dont worry about it .. are you having fun ?? all co-ax's are toys at heart. it is not designed to be precise.

I have a Axe cx Micro and to get it to not circle even after your trim is all the way to one side. You will need to adjust the proportional trimmer. on the board. There are two small screw adjustments on the axe cx micro on the front left of the board if you are looking with the nose away from you. you will need to slightly turn the screw closest to the tail end. left or right which ever way you are wanting the heli to turn and you should be able to set your trim back to neutral for small adjustments as the motor does wear after many flights. the other screw is for the gain, how touchy the helicopter reacts to your controls try not to mess with that one to much it is very sensative. Hope this helps.

And even when you get it to near perfect it will change over time and require readjustment.

True....
