700N DFC: Do you need to upgrade the plastic clutch/ starter bearing block to metal?
The kit comes with plastic clutch/ starter bearing block. Do you guys see the need to upgrade to metal?

I think the frame for DFC is narrower than the standard. So does the metal upgrades fit on the DFC?

No it don't fit ,the plastic one looks to be ok any way but I'm sure align will bring ally starter blocks out so we can make them more money

I bought the original blackhead 700n in 2009. At the time I decided to build it with all kit supplied hardware and only upgrade part that failed or caused problems. The original issue With the clutch block is it would allow the pinion to move just a bit then it'd break a tooth off the main gear. I figured if I was breaking main gears I'd upgrade the clutch block. When I assembled the plastic one I sanded the two halves where they join together. This allowed it to clamp down on the bearing tighter. In the years since building it I've never stripped a main gear. Still have *all* the stock lit parts on my 700. True with all my Align heli's.

It is annoying though the more you think of it ?
Align new they had a problem so they released there own metal starter bearing block .
They make a new DFC heli and include a new plastic block .
Possibly they have made it stiffer to stop it flexing but why test this on there customers again surely there making enough money to supply quality parts :-(

Me and my Butty happend to us both , makes hell of a racket when it does it , mine used to jump but not rip the teeth off but u could see the marks where it happend .
I then fitted a third bearing block and the metal bearing block and around the same time they brought out the M1 gears .

It was a problem and seems to be resolved , there will be even less chance of the block flexing in the DFC frames though because its so much narrower

I believe the gear change fixed the problem though , I remember the earlier gears used to wear out fast coupled with worn bearing in the clutch and main shaft then under hard pitch changes you could make the gears slip easily .

OP,
The plastic clutch stack bearing block works perfect so its up to you if ya wanna upgrade..Ive had 2 older 700N's with black heads and one newer 700N LE..Ive put hundreds of flights on them bone stock with no upgrades..Feel free to click the video title and look through my 700N videos on youtube.

Watch at YouTube

If you do,you'll see all I ever had to do was change the clutch shoe and liner..Heli had a few hundred flights and needed it haha..I also have a bunch of videos of my first gen 700N flybared which was problem free..
Seen well over a hundred at my club alone in the past few years and never seen anyone have issues due to the clutch stack bearing block...You already have it so fly her the way it is and "IF" it starts giving issues which im sure it won't,upgrade it..

Hello guys,

Cool down please. It's just a question that I asked and there is absolutely no need to bash each other up. If it is anyone's fault, I will take the blame. My bad..

Cool. Cool. Cool.

By the way, I really appreciate the comments and thoughts. It was all meant to be well..

Happy flying..
