Align T-REX700E PRO DFC HV Super Combo question

[mswify]

Guys,
I'm buying the Align T-REX700E PRO DFC HV Super Combo, do I need to replace anything? Cause I heard the BEC that comes with the package is rubbish

I was also wondering why do I need BEC while I'm using HV sevos?

How about the bearings do I need to replace them as well?

Bearings are fine. Kit is pretty good. Might want to invest in tail blades lighter than 6 grams such as rail blades. Not all kits are affected but some kits have a bad tail hum with heavier blades. Closer to 5 grams the better. Just use a 2s lipo to power up the servo's. If you do not want to use a 2s lipo then get a quality BEC like this...

If your super combo is a true HV kit then it shouldn't come with a BEC, I have the 700 Pro DFC HV super combo and there was no BEC in my kit nor is there one in the ESC.

A ddj74 said, run the RX and servos straight from a 2s lipo.

You have any experience with this BEC? I have been looking for a decent 12S BEC.

I use that BEC (Gryphon) in both my heilis. Regulation Type is "Switching" so it never works hard and never gets hot. Voltage limit is 75 volts so you can wire it straight into ESC (see pic). note; The extra two smaller wires from the ESC are Telemetry.

Originally I ran 2s lipo but like BEC way better.

I use the gryphon GSR-7075 LMT on my 700DFC HV kit as well. Works great so far. Light 3D flying

I've used similar from that company and was rock solid...many here have with no issues. I'm planning on getting rid of the 2s lipo but going for the big dawg bec on my Gobber...

Cost a lot but probably one of the best in the market. Love the lcd display!

ihave the trex 700e DFC HV with DX18 and AR9020 and ESC phoenix ice2 HV with 3GX include.
my question is
I have to install both receiver 3GX and AR9020 or just AR?

if I have to install 3GX and AR9020 together how they are connected?

No, you don't need to connect the AR9020 and 3GX together. All you need to do is connect the two satellite receivers to the 3GX.

no with spektrum radios all you use is 2 satellites with the 3gx. "DSMX satellites" at that.

BUT if you want to use a standard receiver then follow this video...
