FlyMentor Setup By Ivor Hill PLEASE READ FIRST!!
This was written by Ivor Hill to help all those who are interested in using the KSD Flymentor system
PLEASE.... Read though this first before asking hardware setup questions. Any questions please post them in the FLIGHT Stabilization Forum as to not clutter the sticky. Thank you!!! Freaks This should answer and/or solve most of the installation issues associated with the KDS FlyMentor System.. Any issues concerning software installation on a PC or radio system being used should be brought up on the main Forum to be answered. Set Tx swash type to 1 servo, or H1 Aileron,Elevator trims and subtrims to 0, End point to 100% and servo reverses to normal, except the throttle channel leave that at it is. Set a linear pitch curve 0-25-50-75-100. The plug with 3 wires from the FM module connects to the aileron portion the Rx Yellow connects to Elevator port, Orange connects to pitch port. If you are using the FM tail gyro Gray wire connects to the rudder port, Green connects to the gyro gain port. If you are using a separate tail gyro leave it connected as it is to the Rx, and leave the gray and green wires disconnected. The blue wire controls stabilization gain and is best left disconnected during set up. If the elevator servo is rear mounted, looking at the helicopter from the rear . The left hand servo connects to port 1 on FM,right hand servo to port 2 and elevator to port 3. The black negative wire on the servo leads are closest to the USB port and line up with the USB sign. If the elevator servo is front mounted, The left servo to port 2 and right servo to port 1. Leave the blue wire from the FM gyro disconnected for now. If you are using the FM tail gyro connect tail servo to port 5 on FM. Disconnect motor, power up TX and Helicopter, LED on FM should be flashing green, and connect to Helibal Program Check that swash type,blade direction and gyro camera directions are set correctly under the Helibal mounting tab. Tip the helicopter and under the servo tab set the servo directions and send to FM so that when the helicopter is tipped, the swash moves to correct in the opposite direction. If you can get aileron to operate, but not elevator the swap servo connections on FM ports 1 and 2 and start again. Check stick directions and any that are incorrect reverse under the control tab and send to FM. The next step is to re-level and center the swash. First go to advance page and set balancer gain to 0 this will switch FM off and set stick midway 50%. Looking at the heli from the side use the elevator neutral slider under the servo tab to level the swash, looking at the helicopter from the front use aileron slider to level the swash. Then use pitch slider to set servo arms at 90 degrees. You will not get all servo at exactly at 90 degrees just get them as close as possible. Now fit a pitch gauge and under the control tab use pitch slider to set pitch range. Set balancer gain back to + 70. Because the blue wire is disconnected, The FM gain it controlled by Helibal. I recommend you test fly and adjust the gain in Helibal for your first flights before connecting the blue wire and attempting to control gain with your TX, Unless you are 100% sure you know what you are doing. With the helicopter in position mode ( green light ) if the helicopter rocks side to side and fore and aft ( dancing ) in a hover reduce the gain just enough to stop it. If the helicopter is not dancing increase the gain until it does and then reduce just enough to stop it. Just like setting the gain on a tail gyro. You may also need to use a little TX trim to stop the helicopter drifting. If you are using the FM tail gyro, You will first need to switch it to normal mode with a gain value of about 25, either with your TX if the green wire is connected or by using the slider on the tail page in Helibal if the green wire is disconnected. Once in normal mode the tail servo will move to center, set the tail slider so that it is a little off center ( this is to counter the rotor torque) Test fly and slide the servo along the boom until the helicopter will hover without stick input or trim. ( RATE MODE ) Set the travel so that the tail slider and servo do not bind or buzz . switch back to HH and set the best gain. You may need to use a little TX trim for best performance. Note, when you switch to HH the tail servo will drift to one end, this is normal and it will sort itself out when you lift off into a hover, help it a little with the rudder stick. Note, If the blue wire is connected stabilization gain is controlled and adjusted in the TX and adjusting it in Helibal will have no effect, if it is disconnected stabilization gain is adjusted in Helibal. The green wire for gyro gain works in the same way. Connected,controlled by TX disconnected controlled in Helibal. I wanted to add that I use Align PU Gel and velcro strap to mount the gyro. I have found it quite good for isolating against vibrations but does not hold the gyro very well,hence the velcro strap that is supplied with the gell. To test that FM is not being effected by vibration. Power up in position mode with gain at factory preset +70, tip heli and check that the swash is reacting correctly, moving in the opposite direction to correct the tip. Pin the heli down so it cannot take off and run it up to speed. The blades and flybar should remain level, if they tip then you have to much vibration and flying the helicopter will result in a crash. Do not forget to save your cfg file after you have set up FM. Just a note here when you get "as close as possible to 90°" and you can get very close (if not dead on it... you should not worry about the swash level until to do after you get the arms all at 90 now adjust your linkages per finless bobs ccpm video where mixing arms are level and you have 0 pitch in the middle of your swashes travel range. Also after you have verified it corrects the swash the right way and the controls move with the stick the right way you need to be sure you set fm to off (solid red LED)for all of the 90° and leveling steps. A handy tip someone told me was to set my throttle hold pitch curve to 0, 50, 50, 50, 100 so it was easy the nail mid stick and didnt encourage cheating(ie the stick at close to 9/16 or 7/16 for 0 pitch...

If the blades remain level then the swash needs re-setting useing helibal servo neutrals and or mechanicle settings. It should only be necassary to use a few clicks of TX trim. |

You can also use setup card for trimming?

Hi I have a Flymentor installed on A trex 450 XL every thing works fine but if I Tilt the heli forwars or backwards there is no response from the elevator to compensate the movement . The green light flick . I am using a DX7 radio - I checked the wires according to the manual . The swash plate and all controles are working in the correct direction what can be wrong . ( I didnt do any mixing on Mix1 and Mix 2 yet

Is the blue wire disconnected ?. Is the gyro connected to the modual the correct way around, have you changed any of the settings on the advance page ?, is the Tx set for single servo operation,end points set to 100%, subtrims 0 ?.
Did you follow the intructions and set the servos to move in the correct way when you tipped the heli under the servo tab before you set up stick directions under the control tab. Are you saying it corrects ok on aileron but not on elevator Are the servos moving at all when you tip the hel forwards. |

Kds flymentor setup
Hi I have a copterx 450se

I have installed Flymentor on a Copter X 250,, using DX6i, everything is working the right way BUT the CCD. It's doing everything backwards. Move heli forward it says go faster move it backward it says go fast same right and left.. Balance mode is working correctly, rudder is OK.. Just seems the camera is backwards. I have it mounted with arrow to rear as is the gyro, but gyro is mounted upside down.. Using card reader mounting is set to rear.. Any easy way to set this up right??

Yes I have tried to just turn the camera around... Others have said that they got it to work but didn't say how.. So I'll keep trying but as you know this all gets confusing after awhile.. I would just fit the gyro right side up but I run into a interference problem with the boom struts when mounted this way.. I guess I could just remove them..

Thanks Ivor for the helpful information. I am awaiting delivery of my FM but I saw this thread and I am glad I visited. I am a little confused (OK, maybe more than a little) by the reference to retaining an existing tail servo/gyro setup. Is there an advantage to using a separate gyro rather than using the FM for all axes stabilization?

Ivor, I have a MY401, is it better than the FM gyro??? Just wondering, I'm also a newbie on the FM and I'm trying top get the best preformance for the price.
