I am upgrading my 700 to FL DFC head. The question I have is that, can I use 710 blade on FDC head? The reason I am asking, it seems like every DFC 700 I see, most are using 690 or 700mm not 710, that's why I am wondering if is there an issue with using 710mm blades.

You can use 710mm on your Trex 700 DFC. It will not have clearance issues.

Pro
- lighter disc load

Cons
- since it's DFC, you will have to run with a high HS
- thus, this will be harder on your 12S setup
- Battery, ESC & Motor runs hotter vs 690 or 700
- shorter flight on your current setup

Nothing is w/o a penalty. It should be OK If you
- take it easy
- manage your collective
- smooth on your inputs
- keep your +/-100 of a 2k HS range
- +/- 12 degrees on collective
- monitor temps on your set up
- 14S would be ideal

This based on my 400+ flights on my Trex 700 v1 with FBL (v1 & DFC and SXT) with advance 3D. If you just fly around, most like you will be fine.

Hope this help and good luck

with Nitro .. you are limited in power. This could be the reason.

I had found out that Helix 710mm are pretty light and should work for your 700 Nitro.

I run Cyclone 715mm on my Trex 700 nitro with DFC head.
I also use 115mm tail blades

I fly a YS 120SR-X - so power is only slightly lower than an electric (lol)

KDE Conversion

To OP, have you considered KDE head conversion? It still uses traditional FBL head and link but just the main shaft is DFC.

Rudyy,
The answer is no, but certainly I I would like to see the picture.

It looks nice. Do you have to use the same blades holders?

Look into some Helix 700mm FBL. Light and geared towards the nitro birds.

Yes.
Slightly less power than an electric.
But, not too much.

Glow 120 - maybe 4 BHP continuously.
Electric - maybe 10 BHP momentarily/instantaneously/briefly.
