Good news for everyone else than Doctor Mark:

"The inner shaft for Lama 400D will be available approximately on 16 Nov, we
will inform you when it is available."

Ok I just woke up and read this post. My question(s) is:

Who is "WE" in the post? A Vendor? Walkera? Xtreme?

Why isn't it good news for Mark? Is he starting his own extended shaft company? Boy is that a setup line waiting to happen or what?

"We" means Xtreme.

Bad news for Mark means, he does not need to build them himself which I believe he enjoy

[KCV6]

LOL Lars,

I do indeed enjoy the challenge. Thats good news that an aftermarket one is going to become available. From my experience running 22mm longer at the moment is great and just what the 400 needs

Cheers... Mark

While I wait for my converters to turn up I decided to play around with a couple of spare 450 canopies. certainly not everyones cup of tea, but I kinda like a lot of red on the 400D.

Also a decent pic of my dual linked lightened flybar with the 22mm extender fitted. Is flying very nicely in this configuration Still waiting for calm weather to play some more with the paddled flybar.

"Certainly not everybody's cup of tea ... but to me it is clearly the very left canopy in the first picture" !!!

Sven, yeah I definately like the "chinese mask" series of canopies. The Align one was a freebie from the good folk at RC711 as they had accidentally sent it too me instead of the mask and were very apologetic and sent the correct mask with my next order free. I seem to collect 450 canopies, if they are on special when I get other bits I can't help but buy one. Cut back they work really well on the CB180D as well. Just slide the original canopy inside and mark the outline and start cutting.

Well my 53Q3 wreck (burnt out) is coming together nicely now as well, am using a lot of the 400D mod parts on it seeing as they have near identical blade holders and shafts. My workshop is looking like a production line. LOL.

Mark, you have too much time on your hands

I always wondered why they put only one link on the flybar???

You can just produce mate, I can take some

hi gerner ;that is good news about the new inner shaft excuse my ignorance this is an extended shaft if so this is just getting better and better .don't think i am flying at marks and mels level but when i do get to fly it is really good ;had some nice flying tonight thanks for the info on the shaft . cheers mike

I mentioned this before on other occasions - but Xtreme does NOT make extended shafts (I still have not figured out until today why they go and call their way to increase the distance between the two rotor planes "xtended shaft" - when it is not??

There are two - or since Mark (and Hardy&Reiner in Germany) three ways of getting a greater distance between your rotor planes:

1. self made extenders like Marks:
only for people who have the means and the knowledge ... which is probably 2%
2. xtended inner shafts:
this has been done with the 34cm helis for years now (and for the larger ones for the Big Lama from Esky for quite a while). There were many different "rods" that were used ... piano wire, screw drivers, brass rods ...
3. and this is the way Xtreme goes (and its the ONLY company I know doing this):
A "longer" upper head that increases the distance between the rotor planes.


If you look at the stability I dare to claim #2 is the most stable of the 3 solutions ... and also the easiest way to perform the mod.

[Gerner]

I can live with the extended upper head

[blacksteel]

thanks sven for the run down on the shaft thing;will an extended upper head reduce blade strikes .i stumbled across this today at www.centuryuk.com am i seeing double if it is what i think it is then i will be able to order my parts from the uk .sorry forgot to say click on to razor cx cheers mike

You are NOT seeing double mike, at least that is what I would claim ... they do the same thing in Germany (of course, if you would want to be sure, you would have to find someone who actually own a 400D and a Razor CX. But in Germany the Walkera 400D is relabeled as Robbe Blue Arrow XL ... the parts are the same and I would be very surprised if it is different in this case..

As far as blade strikes go ... the DISTANCE between the two rotor planes is what lowers the probability of blade strike - HOW you achieve this distance is basically unimportant ...
... just personally I would prefer an extended shaft over anything else, as the extended head as well as Marks extender don't offer the same stability ... long shaft with a short head is - in regards to the forces that are created there - always going to be superior to the longer head (but I don't imagine anyone would be even able to realize the difference) or the extender (same judgement)

Long story short - theoretically the longer shaft to me is the most stable solution - but I doubt anyone can fly this heli in a way that the difference (or superiority of the longer inner shaft) becomes noticeable ...

They are smoother than a coaxial and drift around in turns due to there being no second set of blades trying to couneract the movement of the main blades. This just means to get nice sharp turns you have to turn it in and apply a bit of power to pull it through the turn. I think thats the best way to describe it. I think the nicest thing with the CB100 is it's brushless out of the box.

Mark

hi mark thanks again for your help sorry think i got a bit mixed up it is the cb 180d that i have been looking at .it seems a nice little heli do you think it would be suitable for someone that has only had coaxial helis ;the reviews and videos that i have seen seem to suggest that it would be ,thanks mike

hey sven ;this is the first time i have seen this ;i suppose it is a good thing if someone like century have picked up then it must be a pretty decent heli ;which is what we all thought anyway .going back to the extended shaft thing is this something you have done in the past with other helis ;if so is it something you are looking at doing for the 400d
