Ok, this is for those still flying with plastic head's, tails, and other parts but you guys with "bling" on your heli's are welcome to chime in too (..like you wouldn't anyway )

If there was a part (or parts) that you'd like to see done differently/better CNC without replacing the whole head/tail, what would it be?

Would you like to see specific upgrade parts that would be a direct drop in replacement for existing easy to break parts without replacing the whole head/tail etc? Or would you prefer to just go all out CNC?

Are there other than tail and head parts that would benefit from being done CNC? Would there be a benefit of doing them "better" from plastic, or would you go straight to metal?

My initial thoughts are:

Flybar Holder
Blade Grips
Anti Swash Rotation bracket

I'm sure there's more?

Just remember if you install one or 2 replacement parts on a plastic head, you are quite possibly transferring a possible breaking (not braking!) force from the metal part to a softer plastic piece.

I tried replacing a few parts first, namely the washout arms & base, swash, antirotation bracket. But when I started replacing head parts such as seesaw, flybar control arms, etc., I noticed that the CNC parts don't always work well with the plastic parts. For example, the blade grips are different sizes in CNC and plastic; the plastic grips should be used with the plastic core, and CNC should be used with CNC core.

Ask me how I know this...

you guys are interchanging CNC with METAL...CNC is not a material its a machining process, plastic can be done by cnc also

http://www.helidirect.com/microheli...v1v2-p-5373.hdx

so I am not exactly sure what you mean when you say "what parts do you wish were cnc"...do you mean upgraded to metal,or more precision cut

to answer the question I actually prefer plastic as I think it survives crashes better.I cant help but think some of these guys chasing vibes ALL THE TIME ,who have metal heads have tweaked something ever so slightly,and you could be chasing that forever.yes plastic can develop slop,but its usually cheap enough to replace if necessary.so its a trade off,if you are crashing regularly I think plastic is good,if you are not crashing so much and want more precision,cnc aluminum is the way to go.but having said that,some of the plastic parts would be fine if the tolerances could be a little more precise

you can CNC any materials, just load it up right tools and program for it. Those things are fun to play with when boss is not around..heh.

I wish I have access to one now, make some carbon frames and other parts.

Far as from HBK2, I'd rather upgrade to BeltCP or HBK3 parts. Most of metal parts are not sold separately.

That's true, a popular CNC plastic is Delryn (SP?). I thought of that when I posted, but then I haven't seen any non-metal CNC head parts for Esky helis (King/Belt particularly...)

Maybe I should rephrase this question a little:

What I'm talking about is modifications and improvements to the original design without FULL replacement. These design mods would be "DROP IN" replacements for the old parts - not an attempt to fit new/different parts to the existing head/tail/frame whatever.

I'm new to this, so my flying skills aren't tuned enough to tell which parts are more or less precise than others .. damn, my own thumbs are't as precise as some of yours

For instance... (only a few that I can think of right now)

Blade grips that fit the original design, but are machined to fit Align blades rather than messing with little spacing washers.

A Flybar holder that doesn't snap at the smallest stress..

I've heard about ESky using low quality plastic in their parts... how about something better? Delrin? Aluminum? Carbon? Take your pick..

There are other parts that are just poorly/sloppily designed/molded too?

Broggyr:

I do understand that replacing parts with metal could cause the stresses could be transferred in or out to other parts. The design is only as strong as the weakest part. So in these cases maybe the goal is not a stronger part, but a better designed more precise part. Or, if metal was important for strength, replace it as a "set" with the parts that would be affected?

Zaw:
I wish I have access to one now, make some carbon frames and other parts.

What else would you make if you had "access"?

This is all just rough "dart board" theory at the moment that COULD turn into something much more tangible in the near future. (wink wink nudge nudge)

Thanks for the input,

I'd like to be able to upgrade my tail maybe on my HBK2 to metal w/o buying the head and have full travel across the slider w/o binding.
I'd like it to cost $25 or less. That's my wish.

What I don't like about plastic is the flex it can have.
If you have say a thin servo arm and a ball at the end, the servo arm is not going to flex in it's rotational plane, but if you push hard enough on the ball, the servo arm will twist causing the rod you are pushing to not move all the way. This can be a good thing however for servo binding since the plastic takes the flex. I just seem to find that metal heads for smaller helicopters tend to fly smoother than plastic ones given the same servos, mechanical setup, radio etc. which of course can factor into the smoothness/responsiveness of the helicopter. Back when I had my first plastic head nitro Shuttle Zx, the blade grips would always break going out to the ball. One or two other plastic links would need replacing also.
I don't mind the spindle and mainshaft taking more of the hit and saving the metal parts. I have to replace those two no matter what since they almost never make it out w/o some sort of a bend to them anyway.

blade400 have good plastic head but stupid blade holder break if you look at it wrong. it also give full pitch if you adjust the swash location use TX PIT values.

HBK2/BeltCP head is Unique among current heli's I would just keep that design but not in Esky approach or any other.

I would just replicate the plastic to metal and make everything interchangeable. replaceable ball links etc and able to mix and match with plastic counterparts.

I would really like to see a nice cnc mount for a Flux Capacitor.

Just convert to HBK3 it give you full range without going metal. Metal tail is wast of money anyways.. I think plastic ones give you better range then metal.
