Default OK will get back to you

I just ground the collar off, the bearings and bush remain the same.
I grind it off a bit at a time until the old collars fits.
With this method if you have the old style collar you will have all you need.
I am getting some more shafts so will do a before and after picture next week.



Spare parts for the new head have just become available.

Well here is some photos for the 450 DFC main shaft with the collar ground off so that you can put the old style collar on, to give you the necessary adjustment to put the new DFC head on the original sport V1.

I did this with the dremel secured and twizzled the main shaft on it to remove the collar.
Keep going until the old collar just slides on.

As the old collar is quite big it will fit snuggly.

Mostly DFC

Don't mention 450 DFC parts availability though

I did the shorter upper bearing mod I dont have many flights on my sev2 with the new head but I will let you all know how it goes but the traxxas bearing 5x11x4 does work and it does allow the mainshaft to drop lower into the body of the heli.

Boogie how did you get the bearing out and replace it?

I've just ordered the dfc and am trying it on a se v1! I know, retro!

you could try beating it out overtop a large socket

apply some heat to the bearing and it will come out even easier

Im just done with installing the DFC on my SEV2, I went with the bearing mod, my old bearing just fell out? Very easy mod. Ive just had a quick hover alls good but ive got way to much positive pitch now, an easy task to recitfy tomorrow. Thanks again boogie for the tip.

Not a problem at all quick question is the swash plate you are using a sev2 swash or a 450 pro/sport swash? The reason for me asking is because your geometry looks a little off where your links connect to your servos and swash. I think that may be a reason why you have too much pitch also try relocating your servos to the outside of the frame if you have not done so, oh and try moving the ball stud on the servo in maybe 1 or 2 holes so everything will be symetrical this is what I did to my sev2 and everything works perfectly.

Yeah im on a pro sport swash, ive got the pitch sorted and back in the correct range - i had to shorten all my servo to swash links by 4 full turns. Thanks for the further heads up i'll prob give them a try laters if the weather holds up. I want to fly it as it is and take it from there.

Anyone know if it would be possible to just replace the inside frame on the Sport V1 with the V2 version? It looks like they have all the same holes but I can't tell if they all match up or not. A V2 upper frame costs around $14 so it's not much more than what replacing the bearing would cost.

Figures, after I take all the time banging out a bearing and replacing it with a thinner one. Maybe this will put the head up just a touch higher? Probably not, either way it's kind of a moot point for now. Once I burn through my 2 DFC shafts I'll replace the bearing back to stock and go for these.

They probably only did it because people were just buying the Tarot shaft and installing a DFC on their SEv2 / Sport v1 anyway instead up "upgrading" to a Sport V2 or Pro the way Align wanted them to.

Hi guys I'm also in the plan of converting my SE to use the DFC. After reading all these conversion threads, I got the idea if I'm right for the conversion that I either

1) change to a thinner upper main block bearing & use the align DFC shaft.
2) change to a thinner upper main block bearing & use a colar with the tarot shaft
3) use a Align SE DFC shaft with its supplied colar.

But I got a question that if I use the colar sitting above of the thinner upper main bearing, does it got enough space to turn the colar screw?

Yeah, there's enough space to tighten the setscrew but you should just get the proper DFC shafts for your heli and be done with it, no sense in changing bearings now that the proper shaft is out.
