Heli tips over when trying to take off
 
when i try to hover or take off my heli wants to tip over. I used the trim tab and set it all the way to the right and that helped some but i still have to use the right stick and move it to the right just to keep the heli from tipping over. any help would be welcomed

watt_the?! 12-01-2005 12:44 AM

can you adjust the control horn at all?

make a note of where the control horn is when it is trimmed all the way to the right...then recentre the trim. Then adjust the control horn so that it now sits in the position where you used to have it when it was trimmed to the right..repeat this procedure until your trim actually causes your heli to be trimmed in both directions.

Control horn
 
Sorry for being such a newbie but what is the control horn? is that the right stick? Also would a blade inbalance cause the heli to want to tip over on its side. This is a new heli from OMP. It is called the tornado and this is the web address with pics of the transmitter also.

Thats a neat looking Helli, I cant believe the main blades and everything are so flexible. I guess thats supposed to be the best trainer Helli huh. A control horn is on the Helli itself. the linkages that connect to the main blades, some Helli guy can explain better I guess.

Hi Gary,
Welcome to Wattflyer. We are happy to have you visit us!
That is a good sale price they have on that heli. The receiver and the speed control are seperate as well another big plus. Your helicopter has Fixed Pitch or FP. This means that there are two servos positioned at 90 degrees from each other. These are the two little square looking things with arms attached to the top and a link on the other end that goes up and attaches to the swashplate/washout assembly. These are what moves to control the cyclic movement of the rotor head. When you wiggle your controller sticks, these are what moves around and makes a gear noise.
The control arm moves back and forth pushing or pulling the swashplate
around. The linkages on these arms are adjustable by simply (but carefully) popping the link off and twist the end that has the plastic link accoringly to make the proper length adjustment to the linkage.
Set both of the trims on the right stick to center. Now look at the control arms, They should be straight at either 90 degrees from the servo or in-line with the servo. (I am not sure how the servos are placed in your specific model) If it is way off center, you might try to take the screw out of the servo that holds the arm on, pop the arm off, (Be sure your servo trims are centered before you do this) and see if you can move it a tooth on the servo spline and slide it back on closer to center. If that makes it worse, then put it back where it was after you pop the linkage off and adjust it. I know that sounds like a lot of stuff, but it is pretty basic, and you will probably see exactly what I am talking about when you start looking at it. Helicopters require a lot of trimming to get the bugs out. The main thing is to keep messing with it until it works for you. If you need any help please feel free to ask. I am no expert, but I have messed with a few heli's I have a Hummingbird v3 that is basically the same mechanically
I hope this helps :) Please stop back in and let us know how your Tornado is working out for you. Best of luck!

The newbie
 
Thanks so much as now i understand better and im in the process of adjusting this now. I thought something was really wrong but you explained it very well and i see how to make this adjustment now. I want so much to fly the heli but as im new im taking my time and using the flight sim first and just trying to get it to hover in my house. I have heard that the bigger electrics are more stable to fly and if so what do you recomend as money is no object here. thanks again:)

zappedalaskan 12-02-2005 04:13 AM

Hi Gary,
I am glad you are getting the hang of your heli. If you want to fly in your house, I would definately go with the new E-Flight Blade CX. These are the ones with the counter rotating blades. Several companies make them,
but the blade cx is only $30 dollars more than your tornado and you will be hovering around your house within a flight or two. These are the only machines that can truly be run right in the house. They fly well outside too, but it has to be dead calm out. You will find that anything you do to the tornado, will make it fly better, but it just won't work in the house. It is just to shifty once it lifts off. I have been flying for many years and I can't fly my Hummingbird in the house. I ordered a blade cx to fly in the house during the long winters here. Between a sim and a coaxial heli you will be hovering around in no time and by spring you will be ready to take a big step up to collective pitch heli's. There are a lot of real good small electrics on the market today (T-rex, Shogun MX400 ect..) Here is a link to where I bought mine.. http://willstech.com/products/produc...3f2cce8b19cece
The price includes free shipping and the shop owners are members here. So there is online support right here. Will and Debbie Hicks owners. This is one of the only helicopters on the market that you can take out of the box and hover within an hour. I would use this indoors and on calm days take your tornado outside and practice. I hope this helps :) and welcome to the wonderful world of heli's!
Take care,
Jay

heli help
 
Thanks again and i was looking at this same helicopter for indoor flying yesterday and im going to order one to get me thru the long winter here. the blade cx was what i should have ordered first but now im hooked anyway. i wasnt really trying to fly the tornado in my home i was just seeing if i could get it to hover and yes i did figure out real fast that its not the thing to do in the house with this heli....lol. in january i want to buy the biggest electric heli i can and put it up for spring. i would like to try the gas powered ones but i know nothing about them. as you can tell im just facinated with helicopters every since i got to ride one in the smokey mountains.
one more quick question please. are the turbine helicopters harder to fly and are they very expensive? well take care for now. adios

zappedalaskan 12-02-2005 07:22 PM

Hi Gary,
That is a great choice. If you want a big electric, most come in "kit" form.
With that being said you have to build it yourself, which is a good thing and teaches you what you need to know about your Heli. You might want to start with an ARF Heli like the Shogunv2 ARF or an MX400 ARF.
Now as far as large electric helis go, There are several on the market in a lot of price ranges. For one example click on the link below my signature.
These are top end Helis and you would want to have your piloting skills down pretty good. Not because they are hard to fly, it just hurts to wreck them, once you have so much money into the large electrics. A good kit to start with is the T-rex. It has huge parts support and very good instructions. It is a great first heli to build. And they fly like a charm too.
The big Turbines are very, expensive. I have never had the pleasure of trying one to say how they fly. You can do a websearch for VARIO. They have some serious turbine heli's. Hope this helps :)

G'day Sancho
My 2 cents
Skip the counter rotating thingee, they do not really fly like helicopters and do littel to further your flying skills. They are inherintly too stable and end up being a nice novalty item.
Considering you already have a heli , learn with it, it will be more rewarding.
Now on to you Tornado
The roll issue you are experiencing needs to be tracked down, before you start playing with linkages and servo arms set the heli on a table, disconnect the motor if possible, if not be careful.
Once you power it up check to see if the swashplate is level, if the swash is sitting flat dont change the servo arm or linkages. Small helis have a tendancy to be very skittish when getting off the ground and what you are experiencing may be normal. What you need to have is a level swash so the heli wil sit flat in flight, when attempting to take off often it helps to get the heli straight up to 3 or 4 feet height. It seems scary at first but these helis tend to get much more stable as they get a little height.

I think i know ur problem
 
The same thing happened to me when I tried to get off the ground with my CX. When lifting off you may want to keep doing what you were when you used the right control stick. The best thing to do is to get it a couple feet high and it will become stable. It's perfecly normal.:D Also another reason is when lifting off your blades conduct a lot of air forcing it down, but when pushing it down it's getting forced up and hitting your heli. This is a lot of trouble but it's just one of the many things to learn about flying a helicopter:)

Hey great choice on gettin CX
 
I have a blade CX and its a lota fun and really good for beginners. It's fun to fly in the house and outside. It's really easy to fly and get used to but dont get all gitty and fly 200 feet in the air! start out at 6 feet and learn to control it:D . That's it for now.

jcblough 07-23-2006 12:19 AM

I agree w/ ozace. I learned to fly helis my first go round on a blade cp. I just got another blade cp and a blade cx in a trade. I haven't messed with the cp again yet, but I will say that short of orientation work, the coaxial isn't gonna teach you much. You barely have to touch the sticks. My cx will hover hands off for several seconds, the cp you can't take your eye off of for a nano-second.

The CX is a load of fun. Prob my favorite gadget at the moment, but It's not really gonna teach you or prepare you to fly a "real" helicopter.

sorral 12-26-2008 04:06 AM

I need some real help!
 
I just got a Heli-Max Axe cp v3 for Christmas. This is my first RC ANYTHING. I read all the instructions, charged the battery, watched the video, then took it out for its first flight.

I was going to start like the video said, just power it up and try to hover it then land it. The problem was, as soon as it got about 1 inch off the ground, it went over sideways. I think the rotor blades are trashed.

Once I get new blades, I would like to learn to fly this thing, but don't know what happened!
HELP!! It was a nice gift from my father-in-law, and I always wanted on, but don't know what I am doing.. I live in a rural area, and do not have an RC club around to get hands on help or service.

xuzme720 12-26-2008 07:06 AM

Welcome both Sorral and Sancho2!
You guys would both probably benefit from Radd's methods. Go here to see it and get started. I never would have gotten in the air without it!
And if you still need help feel free to ask away! One of us is bound to have an answer...unless something distracts u.....oooh! look a chicken!

sorral 12-26-2008 07:18 PM

Thanx!!!!
 
I have checked out the link, and have read a lot of it. I guess the only thing wrong with my heli is the rotors I broke last night.

All the things I thought were wrong with it, is explained as normal, and that is why the rigorous training to get used to it, and overcome it..



THANX AGAIN!!!!!!!!

sorral 12-29-2008 08:16 PM

i got started
 
I have gotten through about half of the recommended training course. I do feel a lot better about powering up and controlling the heli. I will log back in to let 'y'all know when I am flying.

I do have a question though. Where I live, it gets below freezing, and snows. Will this kind of weather have adverse effects on my heli?

xuzme720 12-29-2008 08:58 PM

way to go! As far as weather goes, YES! lol The cold isn't good on the Lipo's they like it warm, at least 40-50 degrees F. If you keep them warmed in the house or car it really shouldn't bother you too much. If it gets real cold there, you can wrap the bats in something like neoprene (wetsuit material) to keep in the toasty goodness. just pay close attention to the batts temp. for hovering you should be fine like this...

sorral 12-31-2008 06:24 PM

first flight
 
this morning I decided to try my first flight. Have been practicing as instructed. Got the Helli up to a hover, then it started drifting left! I was setting it down when it crashed into the snowman in the front yard:sad:.

Broke the tail rotor, a main rotor, and both main blade grips...checking online now for cost of parts.

this has probably grounded me for quite a while...nice paper weight.

Twmaster 01-04-2009 06:35 AM

Sadly part of the learning curve. Helis are a harsh mistress to master but so worthwhile every time you make a step forward.

jasmine2501 01-04-2009 09:31 AM

Ouch, bummer dude... but you have learned the lesson of the tail rotor thrust!

When the helicopter is properly balanced and trimmed, the helicopter will lean into the tail rotor just a bit - many people make the mistake of trying to hover with it perfectly level, but most helicopters have the clockwise rotation of the main head, which means the tail rotor thrust will be pushing to the left, so you have to lean the helicopter just a bit to the right to maintain hovering. Keep practicing and play with the simulator and you will get it!

Yup, Radd's method works best :)

sorral 01-21-2009 06:36 PM

new parts
 
I ordered new parts for my broken heli. I did run into a problem, When checking part #s in the manual that came with my heli, the main rotor grips # was incorrect. When they arrived, they were not right. I checked the part sent to me with the book, and the numbers were a match. When I did a bit of research, I found that Heli-Max put factory upgrades on my heli at the factory, but did not list the parts in the manual.

When I contacted Heli-Max with the problem, I asked them about reimbursing me the $2 for the shipping on the part sighting it was their book that cost me the shipping charges. They promptly emailed me and offered to send me the proper replacement parts no cost!!!!!!!!!

I get a little hot under the collar about manufacturer mistakes, but Heli-Max was very quick to make me happy.
I am still waiting for the parts (was shipped yesterday) and still do not know how to fly the heli, but I do respect Heli-Max for the quick customer service, and for stepping up to the plate to make me happy. Being brand new to RC Helicopters, I don't know reputations of the manufacturers, or who likes what model best, but I do know that I like what I have because of the service I have received. Now I just have to get it fixed and work on my piloting skills!
:D

jasmine2501 01-22-2009 08:11 AM

That is cool :)

They are getting better I think - certainly the new Axe 400 looks like a better offering from them. It is nice to know they have good service too!
