THi Again,
My question did not bring many people attention (((-:, I understand it is not really exciting ..
sorry to insist I know it is a stupid question but I need help
searching a method to mechanically pull/release/hold my rotor trim (compensator) cable I started wondering if any of the gyro pilots from this forum are using such a device where one has to put one's hand off the throttle to turn the trim wheel ?
Is it ergonomically realistic to release the throttle to trim during especially the ascent ?
(my throttle keeps where it is when I put off my hand from it of course)

That does sound cleaver Rob. Thank you for sharing it.The Xenon uses a really simple system. Two springs attached to a string pulling on the control tube. The spring comes up to the console where it can be put into a tiny sailboat jammer. It weighs ounces, is beautifully simple and works. Takes a second to adjust. I’ll post @ pic when I get a chance
Rob
Yes it is always possible to add more weight, complexity and redundancy to any system.Uh, wow, Rob, sorry, but I can't get excited about that design.
It's like correcting a car pulling to one side by hooking a bungee cord to the steering wheel (vs. aligning the front end).
Gyro trim should have its own linkage attached directly to the rotorhead, all separated from the control system.
Kind of like "aligning the front end".
That way, trim can be used as emergency secondary control.
The RAF, for example, has a particularly inappropriate trim system, which adds force to the control arms/push tubes.
Some owners have added a second gimbal arm on the torque tube rear dedicated to the trim springs. That's a prudent mod, IMO.
No it takes minimal effort and is quite precise. When my machine was newHi,
the small string blocked by a sailboat jammer is a creative idéa !
I am just wondering if it is not difficult to tighten and release the rope finely ?
a trim must not be an on/off system
must you pull hard on the string ?
maybe on a tandem one has to pull harder ?

Vance can you tell me the manufacturer and part number for the actuator you use.
I use a liniar actuator that weighs about a pound.
Good evening Rob!Vance can you tell me the manufacturer and part number for the actuator you use

Good evening Rob!
SOViK 2" 2 inch Stroke Micro Linear Actuator, 12V DC Push Force 22lbs 44lbs 55lbs Built in Limit Switch, Includes Mounting Brackets
This one weighs a pound. If you want more power or a longer stroke they get a little heavier.
Last I looked it was available from Amazon for $50.99.
Brand NameSOViK
Item Weight1.0 pounds
UNSPSC Code39120000
By contrast when I fly a magni Cavalon or Calidus I am astonished at how hard I have to hold the stick and the effort required to turn. I took my last BFR in a Calidus and my arm was exhausted afterwards.
Rob
James Ketchell, the guy flying around the world in an M16, flew a DTA J-Ro and commented that he couldn't let go of the stick like he can on the Magni. Will a heavy stick make for easier hands off flying and make a gyro feel more stable?
