Step 2, solder the postive and negative battery leads from 2 E Sky 20 amp brushed ESC's (EK2-0600A) together then solder to a deans connector. The 20 amp ESC for the tail motor is over kill but I got the ESC in a batch of HBK2 motors I bought for $5. Step 3 solder a HBK2 connector to the tail motor wires that way it will plug into the ESC. The HBK2 main motor that I have installed already has the HBK2 connector installed.

Lookins like your build is coming along nicely.
When you get ready to fly, you will notice what I've said about the tail control being completely independent of the main throttle...

Morning Fellas, Well it's the morning of build day 1 and I thought I would share a pic or 2 of my scratch built frame and all the electronics that need to go into it.

Niiiiiiice!!!

Status: offline 		Correct me if I am wrong. All the guys flying the Century tail have never tried BL for the tail. There is a clear difference when you fly in windy condition aside from the durability. Also the $8.95 is without shipping. The converter is $15 shipped and the $14 ESC is also shipped. As far as the connectors, you don't need them because the motor never break. Solder the wires directly to the ESC. I hope I don't come across as nagging, may be I am, hehe b/c it really is the best and I don't want people to miss out. Is there another person here with a BL tail who can comment on the BL tail performance? Anyway someone has to try it to believe it. Soul has just finished an AR6100 fully BL, may be he can add. Actually none of these messages are directly to you. They are information that others may find helpful.

Exactly!

I don't believe that pot is meant to adjust trim at all. I think that it adjusts rate feedback gain, which is consistent with your measurement. Rate feedback does not help with trim offsets, only with transient response.

Evidently, on the F40, the tab on the transmitter is the only means of trimming SS yaw rate.

I checked rate feedback gain again last night. If it does change it, it's not by much. I certainly didn't see a 30% difference in the output to the tail as I rocked the board back and forth when I set the pot from 0.5V to 3V. I'll play more this weekend and see what shakes out...

Ah ha!
I saw those guys in your photo and wondered about that. It was the only thing I could figure they would be used for. Good catch!

Can you enlighten me on what some of the other parts are? I'm not so familiar with SM parts as you are I'm sure. I was trying to figure out where the RF section is etc yesterday.

I thought they might have been, but I never sat down and checked to see where they where exactly connected.

I'm sure you know some of this, but for the other:
Small black things are resistors (3 numbers correspond to the value, 333 = 33x10^3 = 33k), small tan things are caps. The small black things with three pins (one on one side, two on the other) are either NPN or PNP transistors.

RF is still black magic to me...
However on the first picture, the 31136G chip is an FM single conversion receiver IC (I still haven't found a datasheet for it yet).

Second picture, working left from the crystal socket (with is in the bottom right): CFWM 455E is a Piezo filter (455 kHz band pass), and I *believe* the aluminum box is a tuning coil for the antenna.

Seeker, I bought that frame about 10 months ago. It works well the only thing I didn't like about it was getting the battery far enough forward to get the CG write. I wound up gluing a quarter and a nickle in the nose of the canopy to get the CG write. The pictures of mine are in post 1424 page 57.




Center of gravity is perfect on mine but I'm not using the vertical fin that came with it either. I picked up this
canopy which ships with a lexan tail fin that i taped to the stock vertical support.

I would love to try the BL setup, especially now because I don't have to mess with a converter. I have seen someone fly a Blade CP with a brushless motor and it flew VERY well. There have been others that I heard of using the brushless motors saying that their tail authority was better than ever.

I am torn between further upgrades on this heli (such as brushless tail) or moving up a step to a HBK2 or similar. Won't happen soon due to cash restraints, but there are just so many options that I don't know what to do

I'm flying a 11.1v 1300 mah battery that weighs about the same. It's working well , but I had a hard landing on the cement in my garage last night and broke my frame. Actually, I think it was the boom strike that broke it because I don't think I hit the floor that hard. Anyway, I have a spare frame so I should be flying by tonight probably indoors because we have stormy weather in Phx right now. Temperature went from 110 down to 65 in about 1 day.

Chuck - looks like the build is coming along well. good job. We are all waiting with baited breath to see how it comes out. As far as battery weight goes, just today I decided to give another battery a try. I have one on order but it won't ship until mid-june. So I swung buy my LHS and picked up a common sense rc 7.4v 15C 2000mah battery. I weighs 104g according to their website. I flew my first pack with it this evening. Went swimmingly! HS is through the roof so stability is fantastic. I am using the HBK2 motor and there is plenty of torque to lift the extra weight. The real surprise was flight time. I run a stop watch every time I fly so I know what I'm getting and this time I got a wopping 22min 43 sec flight! It was amazing. I figured that the weight is a bit more than double the weight of the 900's I have been using which are 49g and the mah is a little more than double as well. I figured that balancing the weight with the increased I would get about 1/2 again as much flight time not more than double. I was also expecting that my temps would increase as well but it turned out to not be the case. The temps in the motors and battery are not any higher than before when i was getting roughly 9:30 flights. I don't think you will have a problem with that battery.

Good luck with the build.

Have a great holiday weekend all!

Status: offline 		It Flies!!!! The Beast is alive!!! I got everything mounted, got the servos turning in the right direction, did a quick adjustment of the swash and took her into about a 30 second hover about 2 feet off the floor. It looked pretty good. I need to make some fine adjustments to the gyro the tail wants to do the quick wag back and forth. The swash needs some fine adjustment, but other than that I am HAPPY!!!!!! The total weight with everything installed is 414 grams.

Broggyr, the HH gyro solved the tail motor initialization problem. As soon as the heli starts to turn the tail motor kicks in and brings it back to it's initial position ASAP. The tail did not seem to have any problem keeping up, I was afraid it might with the HBK2 main motor with a 9t pinion and 11.1V LiPo but she did real good.
