have a dx-7 and x9303 and was thinking it would be nige to always find center stick on the collective. Then it hit me, why not put a spring return on it like the right stick. Anyone ever try this or do you know where I can get the needed parts?

I would start the Heli in HOLD and then bring the collective down in Normal before switching out.

Yup, it's been done.......

Try doing a search on "spring centered throttle" or "spring centered collective" to see what you find......

I think that most would find doing so a "nuisance" and possible safety issue.....

Edit: Here's the result of a quick search I just did ......

there are other threads about it too....

just use parts for right stick

I also think it is a bad idea though

I can't for the life of me figure out why you'd want to return the throttle/collective stick to neutral (50%). The only time you need to do that is during setup. If you put a flat 50% pitch curve, you'll essentially have the stick at mid point (no matter where it actually is).

I believe that the proponents of this method (the very few, that is...) claim that they can fly "precision" type maneuvers "better" by knowing when they're at exactly 0 pitch, thus the spring to bring the stick back precisely to center..... I fly the maneuvers I can do by "feel" and "sight" of what the heli is doing as does the rest of the majority ........... I don't particularly care if I'm at 0 degrees or not through any maneuver........

Altrex,

No disrespect meant but please make sure there is nobody in the immediate vicinity (for obvious reasons) after you make this "mod" to your transmitter while starting and shutting down your heli.....

All it will take is one "brain fart" and you'll be yanking those springs out of there faster than you can whistle dixie !!!

I see - and I meant no disrespect either.

I agree however that from a purely safety standpoint, this is a bad idea.

on the safety side

i can see the concern with a hot start, but that can happen with a heli setup in the typical fashion. i just have to make sure i stick to my protocol. i plan on starting in throttle hold and will setup my normal curve such that it will be a fast idle or something at mid stick. On landing/shutdown, i usually auto at the end so will be in hold again, can kill engine with trim then.

the reason i am doing this is i have a difficult time finding mid stick. i want to know where the zero pitch point is and when i am in the po sor neg collective range. i have thought about a detent and may try that instead.

who knows, i may love it, i may hate it. but one thing for sure, i wont know unless i try it.

thanks for everyones comments and concerns.

If you must,

a click detent is much safer...
ultra light, to give you the data you (believe) you want...

after you learn the area, then eliminate it. This really
is wanting something you have no real need for...and
the experience of accomplished flyers documents that.

If you ground practice a while, (no detent)then check for visual
placement, you would likely find that more beneficial
for your desired result. Finger and thumb gripping has literature to show
the placement modality is more accurate for blind movement than
thumbs alone. (more neurons are connecting)

Not everything that can be counted counts, and not everything that counts can be counted.

Altrex - if you're having difficulty finding mid stick then you are short on practice. Plenty of practice in developing muscle memory and KNOWING your helis flight characteristics works wonders. It's like playing a musical instrument; practice, practice, practice and develop complete familiarity and feeling for the required inputs. These can often be nearly immesaurable in precsison flying. As for using the detented left stick, are you mad ? You'll be denying yourself any accuracy in collective control. Just try some more basic manouvers like a forward flipping path when you do a hesitation when the heli is inverted/non-invertd. You need bags of collective control to get this right and any detent will completely screw this up.
Equally, a left spring would be a PITA although perhaps to a lesser degree if you're a pincher rather than a thumber.

Vegetable rights and Peace
