I see these two helis for sale in the t-rex store. It looks like the major difference is the head. Could someone who has experience with the f3c and dfc explain to me what is the difference while flying them. Thank you.

f3c is a type of flying in competitions. Being as smooth and precise as possible in very subtle movements as seen here. To be good at this requires a different type of control than crazy 3d.
DFC is a type of head design ,,usually for much more radical 3D type flying ,,,I will not go any further

Watch at YouTube

Setup is everything, All my heli's can fly far better than I can pilot them

Thank you for the reply. If I understand you correctly, I, as a sport flier would find the f3c head more to my liking than a dfc head.

That I can not answer because I have never owned or flew a f3c head. Hopefully some one with experience will chime in. But I will say you can certainly sport fly the dfc head no problem.

Opinions will abound but if I didn't know what I wanted I'd steer clear of any DFC.

I think that you need to watch some f3c videos to see if that is what you want to do.

I think the DFC head would probably serve you well for sport flying. Just because you can does not mean that you will fly wild 3D routines.

F3C are built to be subtle, but move fast enough for any sport flyer , 3D helli are built to be unsubtle so they can do all the movements of 3D real fast, me, I am a sport flyer and would pick a F3C any day, my 2 cent.

I think Align is using "F3C" as code for "non-DFC". Both should be able to pull off the same manuevers relatively well.

I would buy the F3C myself.

E820, Raptor G4N, X50F/E, E620, Forza 450, and some planks.

I'm a 3D pilot and I'd buy the F3C.

The swash-follower-less hype seems to be ending. Was big for a while. I think it's people not wanting to deal with the requirement for rock hard dampening and knowing in the back of their mind that any teeter whatsoever is stressing the pitch arms. And it doesn't functionally do much except lower the head profile, which is plenty low on models that incorporate the swash followers in the base of the head. Was form over function, IMO.

Keep in mind that this heli was designed as a camera ship, only the massive power available without that equipment has drawn the 3D crowd.

Anyone remember the Avant programmable heads?

Back in the "flybar" days.

I dislike DFC heads. Im not supposed to use the word hate.

If that is the case I own a Align 700 V2 with the pre DFC FBLs head and I own an Align 550 DFC pro. Between the two I prefer the V2 pre dfc head overall.
And even more so I hear if you want to explore low head speeds which would be really great on a 800 and the DFC head may have problems I have heard.

With designs that integrate washout arms into a reduced height head block, there are now precious few reasons to stick with a DFC design. There is absolutely nothing that a DFC head can do that an appropriately configured conventional head cannot all the while allowing total tuneability for any style of flying at any desired headspead and with no demand to maintain the head utterly free of teeter.

I agree,,,the only good thing about dfc I would say is it does look really cool. But then again my circa 1995 Min Air 1005 gasser looks even cooler with a flybar and all it's gismos AND Mechanical Mix and all!!!

I second what Ben and the others said.
Furthermore, there is no added value for a DFC head even in comparison to an ol flybar head.

A STD FBL head will suit you as well, but if the choice is between f3c and dfc, f3c all the way. That head is also tunable for more agreesive flying with just changing the paddles.
