Well here it is guys. The new tail set up seems like it will hold quite well once I get the gyro gain sorted. I'm still trying to get the tail rotor to not come to a full stop with full right stick. (Tail motor is Direct drive puller)

Here's my set up

Brushless outrunner main and 25 amp Align ESC (Out of Blade 400)

Brushless out runner tail and HexTronik 10 amp ESC. (With USB programing)

GWS 4530 push on prop with propsaver.

GWS 6 Channel micro receiver.

E-Flight G90 HH gyro (Also out of Blade 400)

TP 1320 MAH 3 Cell lipo

JR 6102 TX

The beginning

New tail motor test fit

Tail ESC and wiring.

Tail motor wired

The two ESC and the wiring I'll use to connect everything. The JR servo extension will be soldered to the tail ESC.

Tail ESC wiring done.

Done

Cope, I'm really curious to see how the outrunner tail works out. The inrunner tail works pretty good but I betcha the outrunner stays cooler and allows you to run a bigger prop. Please post your findings.

So far just doing hovering tests the tail motor is always cool. Using the puller set up it is always blowing over the motor.

I tried a modified stock tail prop last night (modified by drilling out the prop shaft hole to fit the larger prop saver mount.) I will try trimming the stock tail rotor and see how it works. At full size it was a little to much prop for the little out runner.

The main motor looks like a HeliDirect HDX300 motor but where did you get the tail outrunner ???

Yep you nailed it, The main is the (POS)HDX 300 out runner.

The tail out runner came from Hobby king in China.

See here. ( It dose appear they no longer list them on their site?)

Spec.
Model: 1811-2000
Kv: 2000rpm/v
Weight: 10g (With wires and mount)
Suggested Prop: 7x5
Suggested Power: 7.4v
No Load Current: .4a
Thrust: 130g / 5000rpm
7.4v no-load speed: 15000rpm
Peak Eff Current: 5.5A
Shaft: 2mm
Diameter: 18mm
Length: 30mm (including mount & shaft)

If you do order from them be prepared it may take a long time for you to get you stuff. (Even if you pay the 18.95 or 3-5 day delivery. )

I will say I'm VERY happy with this set up so far. I need to wait to go to the field tomorrow and really ring it out. I have hovered two packs in the living room in both idle up and normal. This thing flys so good I see a lot of house flying in it's future.

I'll let you know tomorrow how it dose under full loads!

I have had great luck with the HDX out runner as the main power source in my CPP. (I swapped the brushless inrunner Park 370 out of the blade to reduce torque on the main shaft of the HDX. I'm also flying the stock plastic head on my HDX to reduce rotating weight+ using Stock BCPP main gears and shafts.)

The blade CPP handles the power of the stock HDX 300 outrunner great.

I have an EVO 90 as well as a Shuttle Zxx and something about this little bird just draws me. I love to be able to fly collective pitch in the house.

Not to mention as long as I don't wreck any of the electronics most parts are 1.99..

I think this will be a great heli to teach my friends on and let them crash at will. All the flight characteristics of the larger birds at one millionth the cost.

I just cant say how happy I am with this build!!!

Thanks for all the help.

IMO the HDX 300 heli itself is a POS but the HDX 300 motor for 19. bux is a Fantastic motor. Mine is over two years old and runs Great. Best 19. bux ever spent in this "potentially expensive" hobby !

Yeah Doug the HDX outrunner is a great motor. The POS I was referring to is the HDX kit.

Can any one recommend a decent head speed for flying carbons?

This thing really seems to be screaming.

Cope, Some folks have run 3000 HS, or higher but its really a personal preference. I'm not sure what mine is-- maybe 2800 or so. What size pinion are you using ??? You could try one with one less tooth. I'm currently using a 9 tooth with the 3800 kv outrunner.

I'm running the 9 tooth as well. At 100% Throttle in idle up.

3000 sounds like where I'm at. Or darn close to it.

I went to tach the thing just now and the battery in my tach. is dead.

The thought of one of those carbons cutting lose kinda gives me the willys. It's not the blade that I'm afraid of, It's the cheep plastic head giving up that worries me.

I got my charger fired up and cant wait for the sun to burn off the snow from last night!!

I'll let ya know how it goes.

Thanks again.

resurecting CP Pro
I have also built a CP Por with brushless main and tail
I am using park 370 main and a fiego tail motor
got it up a couple of days ago
a little of tweeking and it will be awesome
I also have a HDX 300 on the shelf looking pretty, but not flying
I am having a bit of problem with the tail holding on the CP Pro
a bit more adjusting and all will be good
not able to put the stock canopy on it due to the battery size

Out door flight report.

This thing is pretty sweet. Flies great, but still has issues with the tail stopping. (Hextronik computer programmable 10Amp ESC DOSE NOT HAVE A HARD START OPTION!!)

I think a better programmable tail ESC may be the ticket.

Over the weekend we had 15-20 MPH wind on the lake and we fly on the shore, So some wind to deal with...
The Tail set up held fine, Response is lightning fast. Faster than I need.

I'm still having issues getting the tail to hold rock solid. Just when I think I've got it I goes. This may be because of the motor driven tail and varying battery pack voltages? Or It just may be my gyro set up.... I will readjust and report back.

A few notes on the lighter side of this little heli.

The wind.

While flying in a heavy breeze with some large gusts, I had the CPP up about 60', Much further than I normally fly. The wind started gusting and I decided to bring her back down to a more normal level. Here's where things get interesting, It WILL NOT come down! I'm flying in normal mode and continue to drop stick, Nothing. I drop the stick and watch the blades slow, tail rotor stop, Pyro starts, Still not dropping!
Well I figure full down stick ought to do it, I drop to 0 throttle and watch the blades d@m near stop before it decides to come down.

Note to self, Next time use Idle up....

After the resulting crash and repair one of the guys in our "Club" asks if he can try to fly the CP. I tell his sure but "It's kinda tricky to fly."

He proceeds to get about 1/2 inch off the ground and ball the sucker up!
I could tell he was upset, so I just laughed and told him it was probly still ok. (Broken boom, Bent feathering shaft, and landing gear) I lifted it off for a quick hover just to make him feel better and put her away.

It sure is funny how folks think they can fly these little bird just because they can fly a 400 or 500. Nope sorry, not the same!!

After the crash we were talking and he said "It never even crossed my mind that I might crash your heli..."

Ha gotta love the training aspect of these little guys. Once you can fly this sucker you can fly anything!!

Thanks guys.

I think We're all gonna have to wait for the weekend, The wind is really ripping today so flying out side is not an option.

A few questions

In my gear travel menu (Gyro gain) I'm at -150 This setting keeps the tail prop stopped. (but it will still fire up if I spin in a circle with the heli in my hands.) +41 HH mode? This setting has the tail prop spinning fast. I switch to this just before lift off. Once the main is spun up some. In this setting the tail seems to respond faster to me turning in circles. That's why I'm thinking this is HH mode for this gyro.?

By changing the numbers in Gear travel I can make the tail motor speed up or slow down. I assume I should leave these numbers allone and adjust sub trim from here on out?

Rudder travel
R 100%
L 100%

Sub Trim.

Rudder
L 56

By changing the amount of sub trim I can also change the speed of the tail rotor.

So, Witch one should I be adjusting and how do my #'s look? ( For best tail lock, and lets not forget there's still the gain on the gyro itself)

A gyro question. Because I'm running the ESC off the gyro, Should I run the gyro in DS mode? I tried DS and STD with out noticing much difference.

In my first post I said Full right rudder made the tail stop. It's Full left rudder that makes the tail stop. I tried putting the L rudder travel to 0 , (The lowest you can set it.) but it still allows the tail to stop. I sure wish I could set it to, L rudder travel -5 or so..

Let me know what you want me to take picks of and I get em up.

Thanks again.

Another thing I forgot to mention is how good the paper clip mod works!!

That is a cool trick. Any one not using it search it on this forum and you will not be disappointed!!

thanks to who ever came up with that one!!

I probably saved at least 100 bux worth of center hubs with that mod
I wish I could be more help with the tail settings. Awhile back I had the same exact problem with the BL tail motor shutting off with full left and NOT restarting fast enough--- resulting in 2 or 3 unwanted piros Because I was using the stock radio at the time I couldn't change any settings so I ended up just going back to the brushed DD motor and ICS50 ESC. I'm not sure why but the brushed motor and ESC would always restart faster than the brushless.
Several fellers have had great success with the BL tail including tutelar, micro-maniac and buildem336 to name a few. Lately I've been running a Hacked on King 2 tail assembly on my BCPP--- works pretty good but I'm always interested to see different CP tail solutions.

Something to try (and I have no idea/reason why they might be connected) is your cutoff voltage on your main ESC...

Last night I upgraded the firmware in my CC ESC and turned on LiPo cutoff. My tail ESC (red wire disconnected) exhibited the same condition until I turned off low voltage cutoff on my main ESC. Strange but true.
(Or it was pure coincidence with something else that I changed unknowingly...)

Try it and let us know!

(EDIT Yeah I been busy, A Wedding, Work, Flying, Life. )

Here She is, Reborn again.

Shorted tail boom, Tail switched to pusher ( This allows me to run the numbers in the TX Gear CH. and Rudder closer to zero, Witch I think will allow for better gyro hold.) And solid copper wire landing gear.

Her good side.

Tape side. (Scar face)

Painted woodies.

Naked

Thanks again for all the help.

PS I have yet to try lowering the voltage cut off in the main ESC. I'll try that in the next day or so.

Sorry guys is that to large of a format for your screens?

I like large picks and use high speed so I forget that it may blow out some screens.
