    Re: Helicommand 3sx

    So I have been spending today working on this thing and I still dont have it flying like I like, the setup is very difficult. But that said I have done some initial testing of the SL and bailout features and they seem to work very good. SL is stable and bailout does what you would expect rocket the helicopter towards the sky. I've only got it set to 8 degree of positive pitch on bail out. The bail out I have only tried upright nothing fancy yet. It seems to be immune from the vibration issue the iKon had. About to head to the park and toss is around a little bit and see what this bail out feature is capable of.

    Still not done with the setup I need to spend more time learning about this gyro. For example for the tail it gives you some different tail gyros to choose from. GY520,GY611,GY401,GY401(2m). I have no clue what any of those mean or what the difference is. It flies pretty decent but the iKon felt more locked in after the initial setup. The SL and bailout just flat out work!!! There is no fear in hitting self level or bail out. I was at the park today trying it out and it performed flawlessly every time in every situation I threw at it. If I can get this thing setup to where it flies the way I like I know I will really like this gyro.

    I also made a rookie mistakes in my setup. You need a linear throttle curve when setting this thing up. So when I went to fix my throttle curves I put 0,70,70,70,70 for idle up 1 doh! I flipped it upside down and went to gain altitude and as expected the motor shut off I was able to flip the heli back over and just ended up breaking my tail box. Which cost me $5

    Re: Helicommand 3sx

    Ok I think I figured out the problem with my tail and why it jitters. So these helicommand if you use a sattelite RX you have to run a minimum of 5.5V to them otherwise they will brown out in flight. Its recommended to use 6.0V so I bought an external BEC and set it to 6.0V

    It looks like the cyclics are ok with it although there is slight hint of jitter with them also.
    7.6-Gram DS76 Digital Sub-Micro Servo (EFLRDS76): E-flite - Advancing Electric Flight

    But the tale is only rated for 5.0V
    7.6-Gram Sub-Micro Digital Tail Servo (EFLRDS76T): E-flite - Advancing Electric Flight

    The only difference in the parts number EFLRDS76 cyclics EFLRDS76T tail is the T at the end.
    I assumed they were basically the same servo different gearing. So if the specifications are correct I'll be replacing my tail servo.
    Anyone have some suggestions preferably cheap?

    If you have a low voltage tail servo, then you need to run a step-down on the rudder. If you don't, you could burn it up.

    Yea it's a piece of poop tail servo anyway. I may go to RadioShack tomorrow get 2 diodes and stick them in series with the positive wire. That's if I just don't buy a different tail servo. I might stick some diodes on the cyclic servos also. Even though they say they are rated for 6.0v they seem jittery also.

    *edit dropped it down to 5.6V and its a lot better. I'm learning this HC may cause me to learn some bad habbits lol. It just works to well if you dial SL up to about 30% you can pretty much bang on the cyclic stick and as long as you get the collective right you are safe. Flips, rolls you name it not even having any clue of orientation just let go of the cyclic and its stable almost instantly.

    These will be going all my helis now. I'm debating waiting a while to see if they bring out any kind of newer version.

    Re: Helicommand 3sx

    I have always thought of HC as cheating when it comes to flying. However... for those that are REALLY worried, like myself, about crashing, this is a GREAT option for them.

    And if it calls for 5.5 and you are putting 5.6 to it, it should be okay. I have seen some futaba servos run on 5.6 with no issues, just shorter life span.

    WE NEED VIDEO!!!!!!!

    Yea I just got to keep myself from using the SL and only use the bailout. You will learn absolutely nothing with the SL enabled it really works to well. Doesn't matter if your right side up or upside down just start banging on the cyclic then let go instant hover as long as you got the pitch right. If in doubt hit bail out and it will figure it out.

    These other FBL controllers have a long way to go to get anywhere near this level of functionality at least from what I have seen so far.

    My problem currently is I can do flips and rolls in any direction. Fly forwards backwards but trying to do funnels or just a heavily banked turn I screw up sometimes. My tic toks look like poop and I wouldn't even call them tic toks. So I'm just not progressing and I'm hoping these will get me to where I want to be. I just need to figure out a good activation scheme. I don't like the one I have currently. I use the rudder 3 position switch 0= disable 1=SL 2 =rescue

    What I think I would really like is to use TH switch for rescue and the rudder switch 0-normal mode 1-SL 2-TH but that's mixing more than one channel and I dont think that's possible. Since my fingers and brain are already trained to hit throttle hold when I am about to crash.

    Having SL is nice after a rescue to get orientation back. Rescue can quickly send your heli to the moon if you don't pay attention.

    Re: Helicommand 3sx

    Ok I kinda wanted to wait and see if Helicommand came out with some new products before ordering more but helidirect is finally offering the 10% off for fathers day so I couldn't resist and picked up 1 more Demon. I still think I will hold out for the last FBL controller since I have 3 helis and now 2 HCs.

    I'm gonna stick the new FBL controller on the 700 and move my last beastx to my trex 450 pro. Hopefully my 3GX sells soon. To much heli stuff uggg.... its starting to feel like a part time job keeping them all going.
