Should I DFC my 500e or 600 nitro

[stunks]

Am stuck between which One to DFC, can I have some help to decide witch one to do please.

Personally, if they are both flybarless already with the EFL head then I wouldn't bother putting a DFC head on either. The 500 Pro DFC head needs crazy head speeds (around 2900 to 3000 rpm) which will screw up the tail hub and probably cause it to throw a grip if it's the 500 ESP or earlier that you're upgrading. Plus, it's much easier to replace main grip control rods than servo gears.

I wouldn't bother unless you like changing servo gears after every crash regardless of how serious, well at least in my case that's always been the experience

I've been reading this and some interesting points about servo gears busting on a crash with a DFC head. How does this pan out if the servo gears are metal? Does it do further damage and chew the actual servo motor up instead of the gears or do metal gears still strip?

Cheers,

i have a 450 and 500 with dfc heads I found that with align metal gear servos it would destroy the entire servo in a crash, however, with plastic gears they strip and can b replaced

My 600 has long gone so cant comment!

But my 500 was an EFL PRO, and i changed it to DFC head, and dont regret it, at all.! (500 is best at High HS anyway)

The pro's,
Looks right (the EFL PRO) always looked top heavy, dont care what anyone says the Align DFC heads are sexy as hell
Overall the heli, seems to be in 'waiting' for tx input. (like it's waiting to bite)
Cyclic input is noticeably sharper.
Appears to roll and flip with greater aggression. I.E it's like it initially accelerates on cyclic input faster but with less lag.
Appears to roll 'tighter', and elevator is definitely sharper during fast pullout's.

The Con's.
Needs a decent fbl setup, if doing anything other than 'banging' about.
Eat's servo gears, at any opportunity!

Conclusion.
Whenever my 500 pro is on the 'naughty shelf', im missing out on what this hobby is about. (fun).

Thanks for that, that was my thoughts about the entire servo being destroyed if it had metal gears. So basically when using a DFC head it's best to have servos with plastic gears.

in my experience yes, although stunks has align servos on his 600 with metal gears and plastic horns and dosnt have a problem, the plastic horns break and not the gears

the dfc head is so last year
i'd wait for the new fl head to be released

[bigbladelittleblade]

If it ain't broke, don't fix it!

Have Align 515s on my 500 Pro DFC. They have metal gears as standard. Never had a completly destroyed servo but the teeth on the two largest gears crumple at the slightest whiff of a bang to the blades. Other than ball links and the odd feathering shaft nothing breaks on the DFC but I'm replacing at least one set, usually two sets of servo gears. I've got nothing against DFC heads per-se. I'd just rather rebuild an EFL head than pull the frame apart to strip out and refit servos.

I like the feel of the dfc head but do you need to change from efl ? ........No.......they will fly fine as they are, although I did run harder dampers in mine.
