First E5. First build

[Mikeunger]

Ok guys I have been flying BNF stuff and have almost completed the build on the E5.

I am setting it up as a normal E5 (not stretched )
6S 5000 battery
Scorpion 4025 1100 motor
CC 120 ESC
CC pro BEC
BeastX FBL controller
Spectrum 6i TX

All the wiring directions and such look very straightforward I am not seeing and big challenges there.

But what about suggested throttle curves, pitch curves and so forth?

As of now I am just sport flying, loops, rolls, tail stall turns, inverted stuff......

I know I can just start with a basic generic curve but I suspect you guys have learned the machine and could help me out.

BTW I am very happy with my 450X but WOW the Synergy quality is amazing.

I prefer to use the governor for consistent head speed from beginning to end.  I use the VBar governor, but the Castle governor should do well for sports flying.

As a rule of thumb, the 96mm tail blades spin optimally between 9,500 and 10,000rpm.  If you use the stock 4.0:1 tail gear ratio, that equals to a head speed of between 2,375rpm and 2,500rpm.  If you go with the optional 4.5:1 tail gear ratio, then the optimal head speed would be between 2,111rpm and 2,222rpm.

I used dx8 and ikon and its great. I have never used a governor before, so much easier.

What servos you planning?

[Mikeunger]

BK servos

Bk Servos are fast and powerful. You will really love the way they throw this light heli around..

BK servos

I am interested in learning how well the BK servos work with the CC BEC Pro.  I have not had any issues with either the Futaba BLS255/256HV or the MKS HBL950/980HV servos powered by the CC BEC Pro at 7.5V.  Still, I am interested in learning how energy efficient the BK servos are, and whether they could "overwhelm" the BEC Pro.  Just a few questions.

1) What output voltage will you set the BEC Pro?  I routinely set it to 7.5v for HV servos.
2) What BK servos will you be using?  The coreless 7001HV's or the brushless 8001HV's?  I understand the brushless servos are generally more energy efficient.

[Cliff Chmiel]

At the last minute on my e-5 build I put the bk DS7001hv  on my e-5 cyclic servos, Mks tail servo at the 7.4 v and have been very pleased there fast and powerfull. I think there fair priced too

I am switching over from the bls255/256 combo to BK servos next week once the order goes through.  I love them on my E7se.
Let us know if you need anything Mike.

[Cliff Chmiel]

Mike make sure you locktight the pin in the tail gear and the pin in the tail drive.

[Richard Rollins]

The coreless ones are the ones I use as well. 7001... Work great with my CC BEC PRO.

Rick

[curmudgeon]

OK.  So you guys are running the coreless BK DS-7001HV cyclic servos and the coreless DS-7005HV tail servo powered by the CC BEC Pro without brown-outs or glitches.  That's encouraging.  How high are you running the voltage?  7.5V?  8.0V?

[Cliff Chmiel]

7.5 here

[Rodney Kirstine]

I would think you would want to run them at the highest voltage you can to lower the current draw.
