Help Needed: Hirobo Sceadu Evo 50
I recently bought a Hirobo Sceadu Evo 50 used. I did not get any paperwork with it at all. I’m wanting to set it up with a dx8 spektrum transmitter and I do not have any specifications to put into the transmitter as far as swash plate setting, tail rotor settings, governor settings, etc. If anyone could help me with this I would appreciate it. Or if anybody has a manual that I could buy that would have to set the helicopter up, please let me know.

Manual
I have a scanned copy of the Evo 50 HPM manual in my Gallery. You can access it using this link: Evo 50 HPM Manual

I also have a subset of the SWM version manaul if you need it.

IS this a standard NON-CCPM EVO-50? One in which a single servo controls the roll cyclic, a single servo controls the fore/aft cyclic, and a single servo moves the swashplate up and down for collective pitch?

Flybar or Flybarless?

I will assume Flybar and the NON-CCPM version of the EVO:

Set your SWASH type to "Normal". The Aileron endpoints will set your roll cyclic pitch limits, the Elevator endpoints will set your fore/aft cyclic pitch limits, the Channel 6 (Aux 1) endpoints will set your Collective pitch range.

The rest of what you ask is simple helicopter setup stuff, nothing in particular unique to a Sceadu.

Tail rotor settings as I recall, at neutral the servo arm is vertical, perpendicular to the tail boom, the pushrod and pitch lever at the rear end form a 90 degree angle.

Pick the distance out from center for the tail rotor servo ball such that your servo travels at least +/-45 degrees from neutral without binding the pitch slider against the tail rotor hub or the tail case bearing with your rudder endpoints set at 100% (gyro in RATE mode makes this easy to set). The Gyro travel limit settings can be used to fine tune the travel so the slider doesn't bind up/bottom out on the mechanics.

Right rudder should cause the tail servo to pull the tail rotor pushrod FORWARD. If not, reverse the rudder channel in your TX. pick the heli up, turn its nose to the LEFT and watch the rudder servo. It needs to pull the tail rotor pushrod forward, to the nose. If not, reverse the GYRO direction using the settings in the gyro itself.

Once you get the chance to hover, put your tail gyro in RATE/NORMAL mode and hover. Adjust the tail rotor linkage until the heli will hover without the nose wanting to yaw left or right. Land, recheck/redo your travel limits to prevent pitch slider binding. Go back to Heading Hold mode and enjoy. Start out with a gain somewhere around 65%. Go into fast forward flight and increase gain until the tail begins to oscillate rapidly. Back off the gain until the oscillation stops.

As for your governor, shoot for 2000 - 2100 RPM in idle up 2, perhaps 1800 - 1900 in Normal, and whatever floats your boat in idle up 1.

BTW -- what motor is installed, or will you install?

Head setup is simple. Mid collective, flybar level, and with all trims set to zero, the swash is level, in the center of its up/down travel, all levers on the head are parallel to the skids/ground (center of their travel). Main rotor blades are at zero degrees.

Shoot for an overall +/- pitch range of +/- 12 degrees. Then use a pitch gauge to set your desired pitch ranges for Normal, Idle up 1, Idle up 2, and HOLD. I've begun setting all of my pitch curves to be identical these days, full negative to full positive, no matter what the flight mode happens to be. It eliminates unexpected surprises in flight attitude when changing between modes.

BTW -- since this is a used heli, make sure you go through it looking for damage, bent, worn stuff before flying. If it has the plastic swashplate look for cracks:

Those come from not using a tap to pre-thread the swashplate holes before screwing in the swash balls. Don't ask me how I know.

Is this your first ever helicopter, or have you set others up in the past?

Thank you
Thank you to both of you for responding to my post. I appreciate the manual Lief and will definitely look at it. Dave, thank you for the information, it is very helpful. This is the first time I have had a helicopter. I bought it blind and used with no manual (though now I have one thank you Lief). The motor is os50 max-sx. The only thing I know about the swash plate is that it has 3 servos and paddles. Maybe you call the paddles "fly bars," I'm not sure what a fly bar is. I'll definitely put the manual and your information to good use. If you have any more support, I'll appreciate it.

I strongly urge you to seek out a local RC helicopter guru to help with the Sceadu, if at all possible. An experienced pilot can help look for problems, get you up and running, and get your bird in the air and checked out.

As it is a used heli, can you assess its overall condition? Did you buy this from a friend who flies helis, or someone you never really met? Has it been flown recently, or has it sat around awhile in someone's garage or other storage space?

The EVO 50 is a nice heli, and the OS 50 SX-H worked well in that heli. I flew one with that motor for about six years and enjoyed every moment it was airborne. Parts availability may be a problem, however.

Tucson
Unfortunately, Tucson is the closest large city from here, that has an RC club and people who might be able to help me, and it is 120 miles. I do not know of anyone local who fly RC. I am fortunate that people here are helping me with these issues.

Two things you should do before you do anything with this heli.

1. If there is no one around to help out I highly recommend you do as much reading about RC helis in the beginner section of this forum as humanly possible. Many of us learned how to fly years ago without any local help and had to rely on forums for support. Difference today is that we now have YouTube and other video resources that weren't around back then. There is a plethora of "intro-style" videos on RC helis for you to look at.

2. Buy a simulator like "RealFlight" and practice practice practice.

A couple issues you may run into is the fact that the heli is discontinued and parts support is at a minimum. Also, while this isn't necessarily an issue, the heli's design and technology have been essentially replaced with newer "tech."

In any case the Evo 50 is a freakin cool heli and if you get it up and running you will enjoy it throughly!

Look to http://www.vrchobbies.com and http://www.rcjapan.net for parts support. It is limited and pricey but it's there. Another excellent way to get a wide supply of parts is to put out "Want to Buy" ads on the for sale section of this forum and buy complete Evo 50s off of people for cheap.

Hirobo 50
Thank you Steve for the information, it's much appreciated. I will look into both the websites and I will try to search YouTube for videos. I have already bought a real flight simulator, I'm still not really good at it, but in time I hope to be by the time I get this heli flying.

Wear out your flight simulator! Use it, then use it some more. For starters when using the sim, watch the nose of the heli, not the tail as many beginners tend to do. Make the nose go where you want it to go. As you progress you will begin to warch the heli as a whole.

Concentrate initially on taking off to a low altitude hover for a few seconds, then land. You will build up the needed hand/eye coordination to do other things.

It may be a two hour drive each way to a club in Tucson but it will be well worth it if not just for the initial looking over and setup of the helicopter. If one thing is incorrect it could potentially result in the heli being crashed badly and the cost of repairs could exceed what you might have spent in gas to go have someone who knows helis take a look at it and catch any problems first.

There is a person who actually joined our club who lives more than two hours away because he came out to an event we held once and felt he got so much help and guidance it was worth it.

You might find the same thing.

I agree
rocket_33
I agree with you, I might try that. We are going down Friday for a Costco trip, and I might scope around at a hobby shop and see if there is anyone around I can talk to. I just need to talk to people, If I can find someone to talk to down there I'll make an appointment and talk to see them. The heli is not completely together yet, if I bring it down, I want it pretty much finished or almost in flying condition before I bring the heli down and have them look at it. Right now I'm just trying to find out what's going on with it so I can understand it better, if that makes sense.

Makes perfect sense and I think you are on the right track. It is better to be a little more cautious and take the time than to rush.

Dave, as of now I have not found any local help. I'm searching the web for RC clubs in Tucson. One I've called already, no one there flies helicopters. I'm still looking for help and anything that you can tell me or help me with I'd appreciate

HObbytown USA in Tucson would could be a good resource as well as Bill's Hobby Barn who does fly helis, or used to as I recalled. Both stores are great people. Hobbytown is not your expected store. Their off road track is insanely cool and seen right from the main street they are on!!! Both of these guys should be able to connect you with other pilots.

Jeff, I bought the heli at Hobby Town about 3 months ago. I called a few days ago and the guy I talked to says he doesn't know of any groups that cater to helicopters. I'm going to Tucson tomorrow and am going to Hobby Barn to see if they know of any groups or individuals who fell like helping a rookie. I'm not giving up though. I have to go to Hobby Barn and see if they have Japanese screw drivers and a few other necessities.
