Here is my dual tail motor hack. It's not pretty, but the next version looks much better.

hi sfinckster

Can you please send me more information regarding the 'lipo alarm' that you built? Where can I get a scematic/parts-list for this unit?
Thanks
Bert

I just ordered a bunch of parts from heli-fever, and happened to also find all these BH parts in stock there so I ordered them too.

1 x EK1-0213(SK015) E-Sky Bearings (3mm hole) (EK1-0213) = US$2.50
1 x EK1-0228 E-Sky Center Hub Set (EK1-0228) = US$6.75
1 x EK1-0229 E-Sky Rotor Head Set (EK1-0229) = US$6.75
1 x EK1-0231 E-Sky Paddle Control Frame (EK1-0231) = US$4.38
1 x EK1-0234 E-Sky Pitch Control Link (EK1-0234) = US$3.13

Total of $23.51 and it didn't add any more to the $10 shipping they were going to charge me for the other parts. Hey, if it works, great. If I need more parts, I'm patient. The BCP isn't my primary heli anyway. Hmmm.... maybe with the Esky BH head it will be

you got a way better deal than I did. Maybe I can still cancel mine!

I just checked heli-fever, and the 0231 & 0228 are out of stock. Did you get the last ones? I think that's why I haven't ordered from them already.

That's where I got mine too. They're out of Hong Kong, but they ship pretty fast.

I may have. I got on their web site, then had to take care of a customer. When I got back to the site, a couple other parts I was going to order were sold out. It was only an hour later. I made sure I rushed my order then, so everything in my cart would be available.

As I mentioned earlier in this thread, I started out with a BCP, but bought the HoneyBee CP2 barebones kit instead of rebuilding the BCP after a catastrophic crash. The HB flies much better, IMHO. I am getting much more comfortable flying the HB, and the other day I managed to do 5 consecutive rolls with the HB. I have even trimmed the HB to fly a hands-off circle in the air (hands off for 30 seconds or more).

The only major difference between the BCP and the HBCP2 is the head.

If I can get my BCP to hover as stable as my DF4, I'll be happy. Right now it sort of darts around. I can hold it in a hover, but once it gets off the "bubble", it takes a bit to get it back to a stable hover. A lot of this could be my blades, but I'm sure a new head design would help.
I do most of my flying in my office. As long as I don't go too high (papers blow around on all the desks) I'm all set. I can fly the DF4 around in little circles. Very slow and controlled flight - land on the conference table and kitchen island display, stuff like that. I wouldn't dare try it with the BCP the way it's handling now. My Lama 2 is easy in the office, and my DF36 is too big to do anything but hover in here.

I have noticed that my BCP is a little unstable in my small shop, but if I fly it in the larger shop it is better. I always attributed it to the rotor wash bouncing back from the counters and walls in the smaller shop because they are much closer to where I am hovering. I seem to get cleaner air in the large shop, the walls and stuff are much farther away.

WOOHOO,
I went out this evening to fly and for the first time I feel like I can say I was doing just that, flying. It just seemed to click I guess. I was able to hover for a couple of minutes straight within a 5 foot area, and "bring it back" when it flew out of that area! Not perfect by any means and I'm still not hovering a whole pack, but MAN what a rush. I feel like I'm going from the "thinking about what to do" into just reacting. I am PUMPED.
Kiiski

Congratulations. Yes, it is a good feeling when it suddenly clicks and all comes together.

OK guys
I actually plan on trying to pull a Kiiski this weekend with my bcp. I'm nervous. I think it's because I know I have some slop in two of my cyclic servos. The reason I don't fix is because I know I'm gonna crash and buy new parts anyway but I wonder if thats the right way to look at it. If I do...WHEN I do, I'll wonder if it because of me or because of the slop. Before this, I've only tried hopping it around 2 or three times but that was like two weeks ago and all I've done since is read, read, and read somemore. Any tips Kiiski (or anyone else for that matter)?

Quick question guys!!

I hit my blades against the wall and when i went to straighten them out again, the flybar is very loose. It wobbles back and forth, how do I tighten it up. The blades are floppin all over the place. I tried tightening the little hex nut inside the blade grips but they just spin.

Any suggestions, It spinds up fine without the blades on and nothing is really bent.

There should be a ball on each blade grip, and links going from those balls, to the balls on the seesaw, which is in the middle of the control tray. Is all that still there ?

Are you talking about flopping around when you spin them up? Check the rotor tips for damage. You may have lost the weight in the tip of a rotor. If you did replace the rotors. If this isn't it check the shear pin that holds the head on. The small wire that goes through the shaft. You also may have bent or broken the hollow shaft that holds the blade grips together. You can't see this shaft without taking the head apart. I replaced my head the other day and found out my spindle (the rod) was severely bent and I didn't even know it. I had some wobble, but didn't know why.

Yea, its really just the balde grips that wobble, the blades themselves are ok. One of the blades hit a box in my living room then it twisted around and the blade grip ended up upside down, so i had to take the baldes off and twist it back to normal, that when i founf it to be be very loose. All the links look fine. It spins up (without the blades on) Nothing looks bent. When I spin it up and keep it at almost full throttle and make some Cyclic adjustments, its kinda hard to explain but they react, but it slow motion, very sloppy.

Maybe it is a bent shaft, but i feel like its something else... hmmmm

If the grip flipped over it's very likely you bent the spindle. A good way to tell is disconnect the paddle links from the grips and rotate the grips. If the spindle is bent you should be able to see the grips vary up and down as you rotate them. If it's bent, you need to remove the grips from the head with two (yes two) 1.5mm allen wrenches. If your really good you might be able to grip one side with a pair of needle nose pliers. The hex head screws turn on the spindle so just turning one side won't loosen them. Once you get one side off, pull the other grip out with the shaft attached. Then you'll be able to see if the spindle is bent. Be carefull to keep all the parts in order. They must go back the way they came out. Unless you happen to have the old style head with 2BB grips. This is an ideal time to switch the washers while its apart or change to 3BB grips if you want.

Pulling a Kiiski! LOL
Personally, I would fix whatever is wrong, sloppy is only going to make it harder. I was doing fairly well last week, then, on Thursday, all H broke loose and I couldn't fly it worth beans. I had a servo with a few teeth missing. I replaced the servo and the very next flight was my "breakthrough". The flight after that was tough, and this morning was worse. I was hoping it wasn't pilot error, and it wasn't. My tail motor had spun a bushing, I replaced that and this afternoon, I was back to "hovering". This time, I only had three "barely in control" landings for the whole pack.
It seems to me, that the trick is (and I may be dead wrong, correct me here guys) but when you do a correction, you seem to need to correct, then counter correct slightly, before (or right as) you start to change directions.
Kiiski

Your not "dead wrong", but not entirely correct either. The trick is to make smaller corrections to begin with. Flying helicopters is like bowling. Engaging the brain is dangerous. Once you get to a point where your reactions become automatic, or basicly subconscious (and yes it will happen), you'll be flying 3D before you know it. As I'm sure you already know, it doesn't take much stick to make this bird move. You'll get to a point where your thumbs just do the right thing.

You're doing great. At least you recognized you had a problem and started looking for it. A lot of people who start flying insist the heli has to be junk and just give up. Can't possibly be that last crash that bent something, or broke something that isn't obvious to the eye.

If anybody's interested and have a Harbour Freight store nearby, most of them are having sidewalk sales this weekend. I picked up a precision screwdriver set with metric allen wrenches and nut drivers for $1.99. And an aluminum case with adjustable dividers which will make a great flight case for $15.99. Oh yeah, and a 249 piece dremel accessory set for $11.99

The sales may be specific to your area, but this is too good to keep to yourself.

And by the way, I am in no way connected to Harbour Freight. Except I may think of claiming them as a dependent on my taxes.

I know what you mean. When I raced RC cars, I used to see that all the time, the newcomers saying the car they just bought was a POS. The guys I used to race with always said I was over doing it on the maintenance and set up, but somehow I always (almost!) seemed to beat them! Hmmm. And just as a side note, FULL PACK BABY!!!! I only had it do the "flushing down the toilet" action once and was able to recover. Funny how this 40something gets as giddy as a teenager in love over a "toy".
Kiiski

well I can say I am down right hooked on the mini heli... I am starting to get the hovering down... sort of and it is so freakin cool. I did not think learning to fly would be so rewarding. Much different experience than with my R/C cars and trucks... I just thought that the helis looked cool and boy was I right in thinking that this would open up a new world in RC for me.

Also thanks to all those who have put such great info in this thread! - nice!!!

Is this when I quit having the look on my face like I'm constipated?
(My wife's comment)
Kiiski

Kiski, the constipated look will leave at some point. Then as you start to do tricks, the P-factor will hit. This is when you almost crash and pucker up to the point you are sucking p-gravel up.
