BTW, Boomtown has some fine products. I've bought a lot of stuff from them..
Yes, scale is my thing but sense I crash more than land, I'm tempting to do the pod and boom thing until I can actually do a planned landing. All I'm reading is how much better they fly and look. The look does nothing for me but if it's flying better maybe I'll just do the scale thing when I learn CP, or stop crashing the coaxial.
On a side note, I was flying a coaxial in the sim at the LHS and the sim was behaving like my CX2 does. Point being that I figured my heli wasn't set up right or some adjustment was out of whack but if the sim behaved the same way, maybe I'm expecting to much. Of course my skills DO need to improve (as my sign on suggest) but my previous experience has been with the syma 107g, which is a much snappier heli, imo. I realize the CX2 is a much more involved heli and will put me on track to do CP (the syma won't) but that being said, I guess I thought the CX would respond like the syma.

DISCLAIMER: Not diss'in the CX!! Be cool! I love it, look at it when it's on the shelf.... yadda, yadda, yadda

Brushless

Well, I got my brushless up and running. The rudder was reversed and don't you just think that caused a little excitement on 3s!! For now, it has to be on its best behavior at 2s and normal settings on the DX6i. Then, I'll work my way up to the 3s. When I first hooked it up, especially since the rudder was reversed, it was like a bronkin bull. It was ALL OVER THE PLACE I'm glad I tried it out in the 2 1/2 car garage because in the house it would have destroyed itself and the furnishings. Not to mention my basement rec room has low ceilings. No, Lee, I couldn't patch them if they got marked, they're 12 X 12 old-style tiles.
The whole thing got changed around to:
1811 -2900 motors instead of the C-10's.
10A ESC's instead of 6A.
GA-250 gyro (MEMMS style) instead of the Eflite G110 piezo gyro. Much smaller package and better holding.
The mixer was a problem that was solved with an Arduino microprocessor loaded with OllieW's code.
The battery tray is the typical credit card mod with stock skids. Luv is after me to put the Blade 400 skids and flat plate Velcro stuff on it again. It does keep the heli from tipping as easily.
The V-Tail thread has many of the antics involved with getting this thing going. Luv and Ollie are the real heroes. The switch to the 10A ESC's seemed to give this more umph along with the other motors.
I'll fly this as is with the wimpy settings until I get more time under my belt. I'll try different blades and 2s vs 3s power as time goes on.

Lee, you gotta get that girl off your sig, I cannot stop staring to pay attention to anything else. Hehe. Nice to see KJ with a decent setup. The addition of the 10a esc's is a response to your ealier post noting how hot the 6a versions were getting. It clued me in to the fact the heat generated was a clue of how poorly they were performing and very low efficiency. Heat is always resistance losses due to amperage draw. They work but were killing the flight times and choking off how much power was actually driving the motors. Now your little heli on 3s is gonna scare you. At 100% throttle end point setting on your DX6i you will now have full power. Not sure I would want to see it on 125%. I tell you guys the truth, if you take this outside and full throttle this thing the next instant it is up 60ft before you can throttle it down. And now with those 55deg blades these things rock!

without going through the coaxmixer-training procedure one should go with 100%... if one performs the training procedure the resulting behavior would be the same for both 100% and 125% -> ergo, 100% is the right way to go (or lower if one doesn't want to have all power available )

BTW, nice build, Luv!

WOW!
Now that all the frustrating steam has lifted, I'm glad to see that KJ has one very nice, super flying heli to enjoy. It goes to show you how at times something simple can cause a problem and be easily overlooked.

It's not all rosy. It seems to do something different on each power up. Details at 11. You have to laugh or you'd cry.

There was a recent discussion on the Walkera CB-100 thread about tail wag and one guy said no matter what he did he could not get rid of it. His solution was to put boom support struts on it and get as much tension on them as he could. I've got those on my Lama 4, but can never get them very tight, Do any of you guys have them on your CX-2's? If so, where did you get them and can you post some pics? Do you think they help much?
