Well, I removed the old antenna from the copter and found a piece of thin insolated stranded wire about 2 and ½ times the stock length. I wrapped it around the left side skid legs and on the last length I coiled it over and over the wrapped wire holding the end with a small wire tie. My test flight proved to be flawless.

Next I took the extra tail rotor that comes as a replacement and found a nylon sleeve just the right size to friction fit so I now have a double rotor blade at the tail. This provides extra power to tilt the heli for better forward and reverse movement. Its now much more fun to fly.

Then I put a micro toggle switch to cut power to the LEDs. They are good at night but just help to kill the battery during the day.

If you are having flight problems with this copter, you might try this…

JohnTinker I order two new batteries for my S021g. one 1100mah and one 1300. I was hoping they would be here today but they're not. Is your Heli a s033? I 'm not sure the diff. My S031 came with 1100x 7.4. I've seen some advertised with 11.1v. I'm new to all this but I wouldn't think I could jump to a 11.1v. What size is in the S033?

I stopped at my local TSC and they didn't have them either so I went to a local Hardware/lumber yard store and they had them. I just made sure they were 3x16 by 0115 and mine was 3/4" long and still trimed a little off. It cost me 17 cents. For me it was pretty hard to tell the diff. but pretty easy to do.

Hmm, well I did the mod on mine last week and the heli was more stable (thanks rcwatchman). Next up will be the antenna modification but I've learned that some guys have had problems with the connection of the new wire. I will do further research before doing mine. Also, I thought I read somewhere about a main motor upgrade. Maybe someone can chime in regarding this. Happy flying.

-Cheers.

I bought mine at the Do it Center. The spacers are stocked in the hardware section and they were in drawers. Check Home Depot or any hardware store like Ace Hardware Store. I bought 4 spacers for 47 cents.

The size of the spacer is: 3/16 X .115 x 1" long. You also need a 3/16 drill bit. This is a five minute modification.

-Cheers.

I'm looking to do a mod on the 033 that I successfully did on a Walkera 5 4.
The mod involved taking the controller portion of a rx/controller unit I had laying around. The unit was made up of an rx and controller stuck together with double tape, I believe the unit came from a Piccolo I had long ago. I then hooked up the controller portion to a Spektrum rx and with some tweaking to the Tx settings it flies well. Since the 033 has a 27mhz, which I don't trust, I want to convert it so I can run it on my Spektrum system. I am therefore looking for a coaxial controller 4in1 maybe?. The difference with the 033 is the tail motor for forward and reverse motion which obviously runs on the elevator channel, so I'm looking for a coaxial controller that can also run that rear motor. If you know of any such controller or a rx/controller combo, which can be seperated, let me know.
I could operate the rear motor using a small car esc which has reverse but it would have to be small and capable of the same resolution in reverse as forward... Wouldn't have to be more the a 1amp esc, smaller would be better. Thoughts?

Hey guys,

I just got my Syma 033 today! It was the video Chicagoplaya had that convinced me to get one. I had just gotten a Syma S022 Chinook but it was defective and I had to send it back, and I was looking for something else and found this thread.

Wow, this helicopter is HUGE in comparison to the Chinook even though it was the 'big' version.

I just tried it out in my backyard, and I only wanted to get it to hover a few inches off the ground but the wind is blowing around and it's about 5-10 mph gusts so it kept blowing the heli over on its side so I would have to cut power immediately becuase I do not want to break it right away.

For you guys that have flown in Zero wind, does it start to hover easy? Also, mine seems to want to turn left. Is the trimmer button used to correct that? I see there are no other trims on the radio.

One last question: When it is up high in the air and you just want to fly around, say do lazy figure eights, does the heli actually bank over or does it just fly flat all the time? I cannot see any control that simulates aileron, just rudder.

Thanks!

It has no swash plate and therefore no way to control the pitch of the blade. Motor speed controls up and down, the speed of the upper blade controls left or right and the prop in the rear controls pitch...in order to bank you need to change the pitch of the blades at the right time which done by moving the swash plate.
Gotmine in today...time to mod and play.

Thanks for the explanation CarlP.

I was watching some video on Youtube of the S033 and I saw that they all seemed to have flashing LED lights on the tail boom, yet mine does not have any there, only on the side of the main frame. I thought it looked pretty cool, so I am disappointed I did not get those on mine.

Take the canopy off, you'll see a small 1"x1" board near the motors with a bunch of connectors on it. Actually, you'll have to remove one of the connectors just to get the canopy all the way off. That is the connector board for all the LEDs. Make sure that they are all connected. You can easily identify which connector goes to which LEDs. If they are all connected the unplug the working ones to use as a tester for the others. If the working one do not work in the connectors of the others then you probably have a bad solder joints on the board. If they work on all connectors then the nonworking LEDs are either bad or wired backwards. If what I just said doesn't make complete sense just ask.
That board simply takes the feed from the receiver board and feeds it to all the LEDs.
Of course you can also use a volt meter and measure accross the 2 pins of each connector and see voltage, look at the connector of the working ones and you'll see 3 to 5v, if you don't see juice on the others then you have a bad jolder joint or bad connection under the board.
