Overall, you have a reasonably clean installation.

As noted, the microbeast is slightly skewed on the airframe. Its axes should all be inline with their respective airframe axes. The slight angle at which it is mounted will make the helicopter fly in a less than desirable manner, most likely causing a coupling of the pitch and roll axes in flight. That would be ugly. Realign the body of the beast so its sides are parallel to the side frames.

I would strongly advise against the use of nylon cable ties to secure servo and other cables. With the inherent vibration found in helicopters, the cable ties will quickly wear through the insulation and if left long enough, the wires themselves.

The wire bundle in close proximity to the spinning motor can concerns me just a bit.

Your antenna wires need to be perpendicular to each other for maximum radio coverage. Parallel to each other, although on separate planes does not give you adequate coverage.

Make certain the swash moves correctly.

Forward elevator, the front of the swash tilts down.

Right aileron, the right side of the tilts down.

Positive pitch and more throttle make the swashplate move up. Negative pitch and low throttle move the swashplate down.

Tilt the nose of the heli down, the Beast needs to tilt the front of the swash up.

Tilt the heli to the left, the left side of the swash tilts up.

Right rudder command, the rudder servo pulls the pushrod forward. If that's backwards, reverse the rudder channel at the transmitter.

Pick up the heli. Turn its nose to the
Left while watching the tail servo. It must pull the tail rotor pushrod toward the front of the heli (a right turn command to counteract the left turn). If this is wrong, reverse the direction at the Beast.

Transmitter rudder direction and gyro direction both need to be correct.

+1 on the failsafe setting.

Be safe, enjoy.

Out of curiosity, what do your pitch curves look like? The throttle curves you have in previous posts look like something I used to use in my Nitro helis and really don't work well in electric land.

Is this your first electric powered ship? Is this your first venture into flybarless flying with a flybarless controller?

If you haven't set up and enabled throttle hold, do that before going out to fly. I set my hold value such that the motor will NOT run when hold is engaged. After plugging in my battery, if I am going to move the heli by hand, I engage hold to insure the motor doesn't suddenly spring to life if I bump the throttle stick.

Also, all my flights that don't end in a full blown autorotation, end in a mini-auto. I bring the heli to about a three foot high hover, then hit hold. This allows me to bleed off rotor RPM, and get the heli on the ground with enough negative pitch to make sure it stays on the ground without the tendency to tip over. Fly the heli until you no longer have sufficient lift to make things go bad.

If your pitch curves look like what I think they do, when you switch from normal mode to idle up 1 or 2, your heli is going to make a sudden change in altitude.

My electric throttle curve for normal mode, assuming a 5-point curve is something like 0 85 85 85 85. Lets me move the heli by hand after plugging things in, and a rapid spool up in normal mode.

Idle up 1 is 85 straight across while idle up 2 is 95 all the way across.

Pitch curves in all three modes as well as throttle hold are more or less identical, a straight line going from my negative pitch value to my positive value. This eliminates surprises when switching modes.

First electric build

Hi Dave,
I have five TRexes. A 450 flybar, two 500L (GPro and Microbeast PLUS) all setup by my friend. This is my first electric build and setup. I also have a 700X which I have started to build.

I'm using throttle curves and pitch curves suggested in the manual. Also the throttle hold in the manual.

Failsafe

Hi John D,

How do I set the failsafe on this one? Futaba 14SG reversed throttle, Microbeast PLUS

It makes me nervous doing an internet build. I would hope that you would seek local help checking out this build before you put it into the air. Hard not to miss something doing it in this manner.

Heli Splatter

My apologies for being inconsiderate and even recklessly irresponsible for doing it this way but where I'm coming from, I don't really have much choice. I was spoiled by having a professional staff pilot do the building and setup for me. Not just any ordinary staff pilot but one of the best in Asia. Trained by no less than Yosheide Kurokawa of Black Shark Hobby (builder and mentor of multiple F3C World title holder Manabu Hashimoto. He was staff pilot of Hirobo and Futaba and holds several titles himself. One day he announces that he has elected to drive for Uber in order to sustain his family and no longer has time to entertain my needs. I can't blame him for such are the living conditions in my country. The state of the hobby, specially with RC heli is moving backwards more so here in my country. There isn't anyone to turn to, that is why I turn to forums like RR. I am truly grateful that these continue to thrive and frustrated hobbyists like myself can find solace here.

So to begin with, there is really no one else to blame with but myself for not even trying to learn setup and taking things for granted. My dad introduced this hobby to me when I was just ten years old. He practically built everything for me. Now I am fifty three but I feel I am just a beginning newbie. We all have to start somewhere. I am sorry and please bear with me.

I understand... I am concerned with your safety. I heard you mention that you were flying glow engine helis, so I was not concerned with flying ability. It is just a bit different setting up an electric. I knew that you were struggling with some of the basics, thus my concern.

I remember starting... I watched every setup video I could get my hands on. Still, things could be better. The manufacturers could do a lot to help with video setups of their machines. We are dealing with powerful machines and need to remind ourselves everyday.

The best of luck to you.

did you move those wires I mentioned that were near the motor ?

Ideally you want the separate the high current output of the ESC away from any servo wires as well.

spending time, paying attention

Oops

My bad. I need to do that, separate the wires
