For those using the MH rotor head on their Mcpx, which damper shim spacers are you using, soft or the 3D hard? There's not much difference between them, only .10 in. The instructions stated soft for indoors, hard for outdoor 3D. I'm planning on using MH carbon blades and KBDD, which are slightly heavier than stock plastic blades.

Thanks,

Brian

I used the hard dampeners. Seem to take out more slop and they fly fine indoors for me.

Embrace failure because without it success would be normal.

Thanks,
I was leaning that way. Hopefully I'll be able to start my brushless conversion tomorrow, awaiting parts. Going to try a Clubheli AE05 motor with 8T, 7A esc, AEO brushless converter, V2 Mcpx stock tail extended 1", stock frames, carbon motor support plate and swashplate realignment pin from Astroid Designs, MH rotor head and swashplate.

I never thought I would be going this route with RC helis, but the technology is getting much better, and the flight characteristics are making big improvements.

Let me know how the brushless mod works out for you.....

My V2 brushless setup
snjbird, very nice flying!

My V2 Mcpx just went brushless, it's working great so far. My setup includes: OverskyXP-7A high speed esc, Aeo m5 motor, Aeo converter, MH parts-full rotor head, swashplate, hollow aluminum main shaft, Astroid carbon motor support & swashplate realignment pin assay(CA glued), 140mm hollow tail boom, KBDD new Pro 3D blades & tail rotor, batts-Hyperion 250, Nanotech 300.

There's a lot of information out there, thanks to all that are sharing there experiences.

On the esc, I decided to add the stock Mcpx longer batt. connector, as the esc connector is a little short. I basically assembled the complete esc power system by building a wire harness including, stock Mcpx power lead, esc power lead, and added two short wires to power my converter. Twisted and soldered the wires together, then soldered to the esc board. I mounted the converter to esc, esc to 3&1 board using some thin black very sticky servo mounting tape. I soldered the motor leads to the esc. All soldering was using a Radio Shack small iron 20W kit(had some nice small tips).

I also added some black RTV to motor wires, and converter wires where they touched the board, to keep them in place-worked well. I also added a small RTV to the frame mounting points to make it a bit more secure than just two screws.

The new KBDD Pro 3D blades are the best for me yet(compared to stock, MH carbons, stock KBDD's) These new blades are responsive, but give a nice stable hover and forward flight-I wish they would make a carbon version of them.

I reduced my collective pitch range slightly+- 7%, just enough pitch to load the motor good in climbs without straining it. I'm running a throttle curve of Idle one 100-90-100, anything past 80% seems like 100% to me.

With the AEO M5 motor, just a bit of frame work is needed on stock frame with a Dremel tool. The stock tail holds well for basic 3D so far.

Hopefully Eflite or Align will produce a true 'high performance' micro heli, 2S powered for the future

Very nice clean job razz.
The only thing I would change is the tail rotor. The new v2 blade holds much better than the kbdd. I just swapped them back and forth today to confirm it. My main kbdd 3d pros were only available in hot pink, do they offer new colors now?

Thanks, I'll try the stock V2 tail blade. I really didn't think there would be much difference between them, I added the KBDD after my first hover. The main 3D pro blades are very good! But they are only available in hot pink so far. The original KBDD mains were terrible for me, not straight, loaded the rotor head too much, vibration inducing.

The new Pro blades work great at higher rpm also from the BL motor.

no problems with the V2 board and the brushless?

I may eventually pop on the co5M, but for now mines still stock with the hot pink mains, and can do pretty much to a certain limit. I wouldnt mind a bit more power, like your motor. Is it MUCH more power, or just more good usable power?

No problems so far, I have about 15 flights. The power increase is noticeable, but not huge. It runs at a higher rpm, most say it's smoother, more efficient, and the tail will produce more consistent thrust. You still need good collective management. The BL mod does take some patience, is a challenge to solder, but rewarding like most heli stuff

I would really like to try the next step up in power(H05)motor, but requires a different tail motor and blade. Some have had issues getting that to work with the v2 board...I've read some have had good luck.

I'm happy with mine so far, it's a challenge to fly well, fun to tinker with and fly indoors when it's cold outside. Definitely sharpens your flying skills

If your'e not up to the build, there are a few guys that can do the work for you, check out the site HF...Astroids design...makes some awesome parts, very high quality, very knowledgable, can get you in the right direction.

Thanks! The M5 motor version is working well. Will maybe build a H5 version in the future?

I was doing some pretty large backwards loops, gaining a lot of speed down the backside where the tail would just let go, weather vaining around.

I thought a SR120 on the tail along with Hyperion 550 batts might be fun

i never had good luck with the 120 tail. maybe it was in my setup, not sure.

yea, through looking at posts on HF, most have had good luck with the SR120, but it has to be used with the "RRC" prop, proper gauge wire, higher output motors...there's a lot of variables with all BL mods.

I believe you have to find someone thats had success with a particular setup, and then build it...just experimenting is 'hit and miss'.

I'm hoping that Eflite will build a high powered brushless version of the Mcpx. It's fun to tinker, but I would like to buy a BL version, at a reasonable price, that flies well.
