Default Can anyone help?

I have been strugling with my 110 for 6 months and haven't got it in the air for more that 5 seconds at a time! I have had stability, engine, frame,and fuel problems. Its like one problem after another. After a frame and motor upgrade (v7) I flew it for the first time yesterday. MORE problems!! I got the motor broke in and tried to fly it. First it took a slighty hard landing only enough to snap a training gear, but didn't even bend the landing gear, so i decied to fly it without them. Next lift off, no control whatsoever! I had a bad enough time controling it with the training gear now with the gear off it is like flying a completely different heli. Anyway my question is does anyone live near Ontario California who could possibly help me out and see what the hell I'm doing wrong? It is like I can't dial it in and have any sort of control of it. I am about to lift it of the ground to about 100 ft and then kill the engine and watch what happens.

Thanks
Graham

Killer,
Relax. Once thing at a time When you say you have no control over it, what do you mean? Is the tail swinging hard in one direction? Is it banking hard in one direction? I have a 110 with a 0.069 and it took some readjusting of the ball link pushrods up near the rotor head (sorry still haven't learned the technical term for these). Make sure they aren't binding one another. They should also be at 90 degrees. It explains this better in the manual. Trust me, I know the frustration. It took me awhile to get most of it sorted out. Also, if you have had several hard landings, you might have bent the tail shaft. Mine was bent and when I replaced it, it made a HUGE difference. Finally, I decided to put a piezo gyro on mine. The mechanical seemed ok, but I believe the gyro does aid in keeping the tail stable. Last week while at my parents in maine, I was practicing out on the frozen lake. I can finally hover and have started with FF, although very slowly. Once everything is dialed in, it should handle much better. Also, just thought about something else. Did you balance the heli fore and aft?

I bought my LMH used and first time out I could not control it either so I went over it piece by piece following the manuel. After making the adjustments as per manuel it flew perfect except for the pilot errors Alan

Just a little update. I decided to go electric and what a difference. I got the Choppahedz carbon fiber crutch, Astro brushless with 8 cell 3300 Sanyo pack. I had more flight time the first time it took off as electric than all combined as a gas heli!!. I do have some vibration that I can't figure out though. Not sure if it is blades out of track or out of balanced blades. One question though. When i track the blades on the gound they seem fine but when I get it into a hover they look way out of track. like a 1/2 inch or so.
Am I doing anything wrong?
Hey iloweru care to give a fellow LMH fan a hand? That is only about a 30- 40 minute drive for me. Let me know.

Thanks Graham

I would reccomend you go down to 6x4 (do you know how to re-track the blades). Hopefully the higher rotor rpm may help you a bit with the stability. Watch your swashplate when you start trying to fly, if it starts jiggling all over, you need to investigate some RF interference problems.

Killer,
When tracking the blades put a piece of electrilcal tape on one blade and run the helicopter up to hovering you will be able to see the rotorblade that is higher this way. You need to track the heli at hover RPM. Once dialed in you will probably get rid of all of the excessive vibration and have much better control. Also check the gear mesh at the Spur Gear and the TR Pinion gear if either is too tight you will get vibration from this as well. Use the trick discussed in the manual with newspaper it works very good.

Thanks for the info KLRico and Choppa123. I do have the blades tracked, but i will check on the gear mesh on both gears.
I have a couple of questions for Choppa123.
I am very impressed with the carbon fiber crutch, but it seems as if the crutch flexes a little so that the tail boom wiggles, is this normal? Second, if you can help me with this or anyone else, I am using the Astro 020 with a phoenix 45 controller and 8 matched 3300 Sanyo cells. Every once in a while it looses power for a split second causing loss of altitude, about 2 feet during a hover, and then power comes right back. I don't know what the problem or problems are. Any suggestions?
Thanks Killer

I'm sure you've checked all the connectors.... My second idea would be is the problem with the power, or is it aerodynamic? Does it happen in forward flight?

Killer,
I have noticed the CF being a little flexible in the tail area. I will be moving up to 2mm CF on our next production run. However it should be OK and I have not noticed many problems with my set-ups. Definately check out the connections on your set-up. Make sure everything is solid, wiggle the wires while under power this will usually show you that there is a loose connection if there is one. Also check the length of the wire coming out of your RX if the black wire is longer than 4 inches before being connected to the deans antennae trim it down to 3.5-4 inches and then connect it to the deans. This usually takes care of the problem. It's an easy step to miss, the Lite manual says 3.5-4inches and the Deans documentation says 6 inches. I have found that 3.5-4 is best and will usually get rid of the glitching. You shouldn't have noise coming from the brushless motor since there is no arcing there. Try these and see if that doesn't help. If not give us a call 310-787-9909 9-5pm.

Hey Larry,

Just out of curiosity... Did you ever work at a hobby shop?

Killer,
No I never had the oportunity to work at a hobby shop. Aside from having RC Cars as a kid Lite Machines was my exerience in RC. I have to say the last 5+ years have been an eye opener and I am having the time of my life. The best part about the whole experience for me is talking and sharing ideas with everyone and meeting and flying with people. I have to say that in all of the industries/jobs i've had we are truly fortunate to have RC.

I was wondering because i used to live in southern californa and our local hobby shop's LMH guru's name was Larry. He made some custom parts to upgrade the regular Vmax heli to a .15 r/c car engine. It all seemed like it's too much of a coincidence ... It's a small world after all.

well now i am down to just battling this "new" problem. I have got the thing pretty stable, probably as good as it is going to get. It is this damn glitching that is pissing me off now. Just today because of the power glitch it crashed. I was a couple of feet off the ground, power was lost for a second and slam into the ground.
Here is the setup I am using. Astro brushless 020 with CC controller 45 amp i think it said it came with a 35a but the instruction manual says 45 amp controller. I am using a Hitec receiver and Futaba radio, 8 matched Sanyo 3300 cells.
These are the problems i am having.
1. loss of power for a split second, say every 15 seconds, but doesn't do it all the time. 2 and everyonce in a while it seems as if the motor puts on the "brake" and sounds like it is going to strip the main spur gear which it slowly is. Yes, the brake is disabled!
As chpoppa123 suggested about the deans antanna, yes it is fine like he said it should be and connections seem fine. I have no idea what the problem could be!
Anyone else using the Asto set up have any of these problems?

Hi Killer G:

I'm not sure if you're having the beginnings of the same problem as RotorWing, but check out this link below to another Astroflight situation. Read the first and seventh post particularly.

Also ... I wonder if when the "brake comes on" there are any funny scraping / squeaking / grinding noises?? The motor may be getting ready to throw a bearing, or loose a magnet ?!?

http://www.rcuniverse.com/forum/Anot...1531461/tm.htm

Come to think of it, there were problems a year or less ago with some of the Phoenix ESC's, and I recollect the 35's, but to the best of my knowledge, that has been resolved for 6 months or so. It bothers me, though, to think of how many of these problem components get lost on the back of the shelf in the LHS, or a distributor, and resurface later to haunt us ?!?!?!?

My ten cents worth,

Russ []

I am not sure if the motor or speed controller are bad they are brand new. I think that the reason the "brake" was coming on was my fault. I didn't have the gear mesh tight enough and i think it was the gears slipping! I flew it today and no "brake" sound. I think I have that problem solved. I did though lose power for a split second only a couple of times. It seemed to be much better.
I have one question. Should the speed contorl be mounted far away from the receiver or is it ok to be close to it? I have the speed control held down with a rubber band and it sits on top of the receiver. I few it with the speed control hanging away from the receiver and the glitching seemed to be down by about 95%.
