Trex 700E DFC HV Super Combo

[msallua]

According to the Align website, If I buy the combo with the HV servos I need a Lipo 2s 1900-2300 . and then:

What 2s lipo 1900 - 2300 would you recommend?
As would be the connection?

I do not want to be plugging and unplugging the battery from the FBL unit
Anyone have photos or a diagram of how to use.

Thanks in advance

With an electric you can have two ways in order to power your electronics. #1. Install a BEC in parallel to your ESC (Speed Controller) and have your 12S LiPo pack power your motor and electronics. #2. Have a separate 2S LiPo battery to power your RX, Servos and FBL system.
Personally, I like the separate 2S pack, cause you can charge it once and fly your electronics most of the day. A 2S 2600mAh or 3600mAh and even 5000mAh battery will serve you well. Pulse batteries, NRG Outrage or Proggressive RC's Spyder batteries are all great choices.

Hope this helps you.

Ok, I choose the #2 way , how i connect the battery in the rx ? I do not want to be plugging and unplugging the battery from the rx.

FYI, I'm running the Align HV servos, and at 8.4V I can get my vBar to brown out. At 6V it's stable. So at this time I would only recommend a 2s LiPo and not a BEC in the 700e DFC if you want to run HV to the servos.

I was using a WR Hercules Super BEC (the $100 14s one).

You can install a switch. Something like this if you use Spectrum/JR.

Very interesting. I was under the impression that lower voltage meant a higher current flow for any given load. I wonder if there is something wrong with your Super BEC on the 8.4v circuit?

Why is it called DFC HV?

This is a common misconception for servos. The higher the voltage to a servo motor, the faster it moves, the more torque it generates and therefore the more current it consumes. If the output power remained a constant, then this would be true. But instead it increases dramatically with voltage.

It comes with the considerably more expensive HV servos.

Looks sweet, the flight is not so good though.

Whaaa!!? That flight was amazing. The video wasn't so good but Colin Bell gave that 700 a spanking.

I know that this is not the subject, but I was always wondering why do people like flights without no meaning, no precision, jerky movement without any sense and elegance. Just my opinion and explanation, thanks and sorry.

yes, yes I don't like Tareq either .

What about resolution guys. I am very conserned being not optimal for a CGY750, V-Bar or other units than the 3GX. Any information about that?

If someone can convince me about that I will buy one. Otherwise I will probably go for a GAUI X7 this time.

The resolution is OK because the new swashplate comes with two ball-link positions.

I'm guessing it's better, since this design no longer uses the long bell cranks.
And like previously mentioned: use the inner hole on the swash.
Other option would be the extended grip arms from KDE:

Hobby Hut secured a small amount of 700V3 kits get them now.

Arghhhhh. I want this to be my 1st 700 bird so badly. No funds though.

How much is one kidney in the black market nowadays .

I hope it does add enough. Unfortunally it does not add pitch resolution which is equally important.

As far as I know this is only supported in combination with the KDE DFC arms. KDE only has a bolt on version for the normal 700 head, not the DFC arms from Align.

I can't agree with you more!
