Just received the pictured option parts for the H'Bird Elite CP............on with the build .............Looks as Century has done some homework and the MJP Carbon fin set sure looks better than the stock flimsies.

Do I need to upgrade to the one-way gear/bearing?

Not mandatory by any means, but it will save wear and tear on the main spur gear and if you are going to try to autorotate this little bugger it is absolutely essential.

Hoverup,

I started out with the gyro up front like you but I found that the Rx up front and the gyro in the rear was a better configuration. It’s much easier to get a solid for the gyro in the rear. Give it a try and see which one you like.

Great pictures Boyd. Could you please post a flight report ?
Do you need the power of the Himaxx 2025 or will the 2015
be enough ? I'm getting ready to buy a brushless setup for
my cp. Thanks.
Hal

Sorry about the 2025 mis-label, it's the 2015-4100

I have flown both gyro locations on Hornets and H'Birds for sometime now and have found no difference in performance. With Futaba 240's and 401's, I have rock solid tail performance every time. Can't say the same for CSM HLG 200's, as they don't perform at either location for me. There is no reason based on gyro physics that favors either location, but if it ain't broke don't fix it.
Candidly, my equipment layout was driven by my own experiences on equipment separation for RFI elimination, between things like the ESC's and rcvr. Also the length of the connector leads on the Futaba S-3108 ( very short for a 120 degree CCPM arrangement) drove the rcvr location which in turn led to the the gyro's position. It works fine for me and was easy to keep the tangle of wiring from taking over the heli

Only a few flights to date. The little HiMaxx is plenty powerful and with the low profile "Walt Ferar" mast collar and the CNC head from Century, I am finally able to get a decent range of + to - pitch. I'm flying various ModelSport and "W" symmetrical blades with mixed results but with the headspeed up and plenty of pitch to work with, I am satified with these blades for the sort of flying I do. I dropped the stock woodies due to the flutter factor associated with 2200-2400rpm head speeds that I like to run. I'm averaging about 10-11 minutes on my favorite light weight Lipolys - Apogee 830mah 3s packs.

Boyd,

What pitch range and head speed are you running?

And what is that tail esc you are using?

Regards

Jamie Wilson

+10 to -7 @ 2400rpm
I'm no 3D pilot but this gives me plenty of control at the top of my loops and the belly-up portion of rolls

The tail ESC is a TREC programmable from

http://www.dionysusdesign.com/trec.shtml

You can program the throttle curve to eliminate the dreaded "T/R won't stop spinning without full left rudder commanded" and limit the high throttle voltage when using a 3 cell lipo pack (and who isn't). It's a high frequency ESC that will help keep your T/R motor cool and long lasting. This is the best T/R esc available at the moment IMHO.
