Looking for a super slow moving servo
I would like to find a servo for a set of mechanical retracts that operates extremely slow.
Does anyone make one like this or is there a way to convert a standard servo to have extremely slow arm movement? plaez halp THanks, Mike |
RE: Looking for a super slow moving servo
Is there a reason you dont just use a retract servo?

RE: Looking for a super slow moving servo
You don't need a servo. You need a servo slower!

RE: Looking for a super slow moving servo
Mid to high end transmitters can be set to slow servos, you might check to see if you can do this via your tx. A note: Retract servos are not proportional, so you'd need to use a fully proportional servo for the TX method to work.

RE: Looking for a super slow moving servo
thats awesome!!! you're awesome!!! I have a futaba 7CHP/PCM radio. So I don't know if it will. Don't remember seeing that function...... Do you know by chance? I think it's 'mid range' radio. |

RE: Looking for a super slow moving servo
Actually it's not throttle delay, it is just delay, and is settable on any and all channels in several differnetly places, either directly on the servo channel, on the mix, or on the condition,. I don't know on the 7C, but I know first hand the 9ZAPs, 12DG, 12Z and 14MZ do it.

RE: Looking for a super slow moving servo
9C and 7c don't have the slow feature, except on the throttle. A servo slow, will not work with a regular retract servo. Retract servos are not proportional so they cannot be slowed by any external source. You do not want to use a regular servo for retracts, because it is drawing power at either end of its travel. It's only idle at center. Airtronics makes, or used to make a 94739 proportional retract servo. Not sure of availabilty, though.

Yep.
I don't see the need to ever buy a retract servo. It's not proportional so you can't adjust travel. Sounds like they'd be a pain to adjust the throws and end points with just cables or rods going to the gear. But yea, I'm gona probably get that 10.00 dollar do-dad and call it a win. I really appreciate the help guys. Can't wait to start on my new HoB .20 Mustang P-51 Look for the build thread this week! Mike |

RE: Looking for a super slow moving servo
ORIGINAL: TLH101 You cannot use a regular servo for a retract operation. When the gear are in the up, or down position, the servo is drawing power from the battery. Just as your eleevator servo is drawing power at full up or down. The only time a regular (proportional, non retract) servo is not pulling power, is when it is at center. FEATURES: Positive Up and Down Locks Tough Glass-Filled Nylon Construction Light Weight - 2 oz. Pair 1/8" Tempered Steel Gear Legs Mechanically Operated From Standard Servos ORIGINAL: TLH101 The only time a regular (proportional, non retract) servo is not pulling power, is when it is at center. They only require power to turn the servo's engine when the potentiometer says it needs to be in a place that it isn't currently or has a load on it. If you put one on a landing gear, it goes up, locks and thats it. Goes down, locks, that's it. Unless you have the travel not set right. |
RE: Looking for a super slow moving servo
Agree... if set properly, you can use a standard proportional servo for mechanical retracts. The locks in the gear will keep the heavy load off the servo. If adjusted improperly of course the servo will draw a lot of current, any servo on any surface will draw a lot of current if configured poorly... don't do that.

OK

RE: Looking for a super slow moving servo
Ok so I put the reg servo in #3 and use the throttle delay which is perfect!! How do I get more throw on the servos to get clser to 180*? Can a 9 c do that??

Borrow your neighbors 5 year old so there is someone with small enough hands to get it built. tghat is a very small plane. We used to have a racing class for it, that little plane is really a cooker. |
