Has anyone decieded to use push pull for the throttle on your 600n? I did but am just waiting on the servo linkage balls to come in. anyone have any they would sell? 3 total with the hex nuts. Genuine align only please. Thunder tigers dont work good! Also wondering if the new ys 50 could be ran on push pull? Someone please help me on the linkage balls!?!?!?

Just curious, what's the reason for push pull on the throttle?

There is a very fine line between "hobby" and "mental illness."

Whats the point?

Other than redundency but if you check your links now and then I dont see an issue.

The balls from the T-Rex 450 will work. They are the same size. You can probably pick them up and any Quick Mart!

Are you doing this for some sort of redundancy on the throttle linkage?

The YS 50 comes with a single arm, but could be modified with any servo arm.... I too am curious as to why pull pull?? since it is very little torque, especially with the silky smooth carb on the YS, and the ball links, it just seems like overkill.... kinda like having an 8717 on the throttle, but I am looking for the speed...

But Honey, I can't live with just stock.....

no i really just like the look since all the other linkages are push pull and the throttle looks odd. Whats the real reason they put push pull on everything else ya know!

Push pull is used to eliminate the stress on single linkage systems that are under a substantial amounts of stress. Push pull systems create true two force moments at points of rotation rather than one force moments that result in strained servo horns. Just make sure that your push pull linkage is almost perfectly parallel otherwise you'll create other problems at the joints.

I'm also going to use the push pull setup on the throttle.

My thought is if the frame were to get broken it might help on the chicken dance.

schoenju, whilst I totally agree with you have you seen the setup in a Synergy. They use supports on top of the servo to hold it in place and no push pull setup. So maybe you don't really need push pull at all.

Yeah I have seen that setup. It's pretty slick having those servo supports. I think that having pushpull and cervo supports would be overkill on some situations but that all depends on the situation.

Push pull on a throttle, overkill for torque reasons, somewhat justifiable for redundancy issues. It's your bird though!

The servo supports (bridges) and pull-pull linkages do the same thing. They are mainly to help with servo output shaft wear. Having a pull-pull linkage on something that requires considerable torque keeps wear to a minimum. The servo bridge (as I call them) do the same thing with a lot less linkages to build. Build an EVO, with all those linkages and you will have sore fingers when you are done. I prefer the bridges. Keeps things simple. I personally don't see why an servo could not be incorporated right into the carb of an engine. It would not need much torque to turn the barrel and instead of a mechanical linkage you'd have a servo lead.

Like this?????

Or a small servo integrated to the carburetor??

That is a nice idea!!!

A fast micro servo integrated right into the carb. It would need very little torque to turn the barrel. It would also end a lot of BS when it comes to setting up the geometry of the linkages and probably save a little weight to boot.

Now that's an idea. A mini servo attached directly to the carb throttle. Like an HS55 and design it so that it would be totally rebuildable.

It would have to be fairly tough. Governors work them pretty hard. I think an OS50 with a choice of mechanical throttle or integrated servo in the carb would be a very nice option to have. I'd pay the difference! The idea could be applied across the board to other engines, plank engines included.

You would need to isolate it from the engine vibes though else a small servo would fail i guess...
