What tail rotor blades are those pictured in the above link (black & red)? I would like to purchase to see if they make a difference from the stock 120SR tail rotor.

[GravityJunkie]

I believe they use Walkera/Novus tail blades:

Looks very similar, just doesn't have the white on it anymore. That's the blade I run and it works stellar.

Yes, specifically the 4#3B tail blades. The 4#3Q are larger and are white with the red tips.

First of all thank you to all who have posted on this site as there is so much information here, I find something new each day.

I have finally learned how to fly enough (lite inverted hovering, flips, circuits, weak FRF but getting there) to commit to going BL. Although I am not an expert by any means I do want to develop my skills on this little guy and a simulator till I’m good enough to commit to the bigger birds. Since I suspect it will be some time till I buy new heli (and my wife allows me to drop the coin) I figured BL would be the way to go to have a powerful enough machine that I can fly anytime and not kill my bank fixing it if I crash.

Anyhow now that I have a HP05 and 9T on the way I’m concerned I may have a bit too much power and not enough battery life. I only fly outdoors which I understand is where the HP05 is better. Should I try a HP05/8T pinion combo, stick to the HP05/9T, or try and find a C05M/8T combo (which seems to be impossible to find in stock these days)?

I know this a loaded question and many have their own preferences but I’m not a 3D flyer (yet) and I figure the more time I’m in the air, the more practice I can get in.. or am I completely off and am better off sticking to my decision and buying a load of Batteries?

Anyone know where I can get a 1.5mm 8T pinion and where a C05M is in stock? Maybe Ill get both and try for myself.

Thanks again to all!!

For what its worth stay stock for indoor flying. I fly mostly indoors with this lil guy- 3D in our shop, flips rolls huricanes circuits etc.. Just did a bl conversion to try since i have motors and speedys laying around from walkeras. One word RIDICULOUS! Its hard to keep smooth in a tight place unless ur a 3D pro freak.

In my opinion find a battery that will output more power/upgrade connectors.

One question.. How the heck are you guys getting good cg with the 120 motor on back?
I have my 325mah pack as far forward and its still super tail heavy.. Custom lipo tray??

How long is ur tail boom
Make about 5 3/4 long

I can probably shorten it a small amount..even more with a smaller blade. thats next in line..

I am still using the stock tail motor on my BL setup. HP05S with a 9T pinion. I went to a 7" long tail boom, trying to make things easier on the motor. It's actually pretty good, even in pitch pumps, with 70% travel adjust, in IU at 100% throttle. Using 26AWG tail wires (120SR size), direct-soldered to the 3-in-1.

Today the tail was starting to not hold as well, and I could hear the tail motor "singing" at full bore sometimes. So I bent the tail rotor to add more cup/pitch to the blades. That helped.

Went home and cut down a 120SR tail rotor from the stock 2.5" or whatever it is, down to 2.0". Had to CA the center hole, then drill it out to make it fit on the stock tail motor shaft.

Tried it out, it works quite well. Pitch pumps are still fine, and I can give more extreme collective & cyclic inputs, and the tail still holds. Better than my stock tail rotor, certainly. The tail motor gets warmer during use, vs with the stock tail rotor. So it's working harder, but it's not even close to hot. And I really like the white tail rotor, it's easier to see :) Having taken off my tail fin, the tail doesn't always show up very well. It makes me think about coloring it with a red Sharpie or something, to make it even more visible.

I don't really notice wag problems or anything. It's still not perfect. I'm sure the 120SR motor, or dual coreless, are better. But for $2 or so, available locally, it's pretty easy to try out. And it's better than the stock rotor, even when just using the stock motor.

Hi,

I'm still running everything stock.. and always have a tail blow-out.. I'm sure is my poor cyclic management..

Do you think by lowering the pitch % will help..

I'm running

Normal mode
35-50-100
IU-1
0-50-100

thanks
quest

[s0laris]

Yes it will help

[questerng]

Hi,

Thks.. Will try that.. See how different it will be..

[questerng]

I hear alot of reducing the pitch %.. what would be a good starting point.. 70%..? 80%..

Bare in mind I'm running stock main and tail motor..

Start with 70% then go to 75% may be ur Max unless u have done the extended tail boom if have done this then you can take it up to 80%.

Thanks bro,

I did extend the boom..

will try it tomorrow and see what happen.. will this compensate for my poor collective..

hopefully this will let me enjoy the mcp X more.. while I learn to better manage my collective..

cheers
and god bless..

I would really like to connect the yellow wire to the back of the board but I cant determine from the picture exactly where to solder the wire.is it on the right solder joint of the little black component. Mine has a little resistor just below this and I cant tell where exactly where the yellow wire goes.

[RedOctobyr]

Take a look through Matt Bockman's excellent conversion guide. About halfway down he has a good picture of where the yellow wire goes. Click on the picture to view a larger version:

thanks I looked at that pic until 330 this morning but I didnt think about enlarging it. With it enlarged I can see exactly where it goes. Very happy now and thanks again. This is one awesome group of guys here on HF.

Well I am ,, don`t think the rest are he he he,, Oppss Did I type that out loud :-)

They are ALL a grate bunch of wa.... oppsss Guys and very helpful, hats off to you all.

[QUOTE=dbennettya;3145866]8T pinions are pretty much free if you remove one from the stock motor.

I've found with that combo that I really like the performance with a 7T pinion. Climb rates are awesome and after 5 minutes of tearing up the sky I put back 200mah into the 300mah Turnigy Nano batteries. A big plus is that this combo doesn't bog at all :)

Don

your setting sounds great! i have the HP05 with 9T and i also think its to head speed VS to low moment force. your flight times also sound great.

could you please tell me where you bought the 7 (and 8) tooth pinion?

thanks

Omer

[questerng]

Hi..

I've tried reduce the pitch % to 70.. And it barely Hoover.. Then 80%.. still not much punch.. Tried 90%.. It feels better.. For recovery if I loss it.. If you know what I mean..

When I flip.. Tail still blow out.. Makes me think the tail motor might be on it's way out..

Well., I'll try a new tail motor and see what happen..

Thanks for everyone's help..

[tntburnett]

make sure you have zero pitch at half throttle. if not turn each linkage two times up. if you have done that make sure your gear is pressed all the way up against the bearing.

Have a Blessed week

I saw you new video using 12T. I have followed your instruction in video and post. Purchased Helimax Novus CP brushless conversion kit and steves converter. Motor runs fine with out shaft installed. However, once I install the main shaft with gear the motor will not turn the main shaft. Any assistance is appreciated.


Thanks!

If I'm understanding your question. It sounds like you need to elongate the motor mount holes in the frame so you can adjust the mesh between the main gear and the pinion.

you have to turn the main gear manually first so the pinion meshes correctly to the gear, this is bec. the mesh is too tight. When you turn up the throttle, you may even have to help it start up by spinning the main gear while it's on.

I think he's running a 12 tooth pinion. The 9 tooth is tight but I'm surprised he could get the main gear on with out moding the frame.
