My 80m 2L beam is destroying rotators (sm PP and Orion 2800). So far no problems with the beam. What is happening is any backlash in the gear train leads to rotational oscillations from the turbulent
I should add that the brake isn't needed for start-stop braking, the RT21 does than well. It is intended to prevent wind driven oscillations when not being turned. My 80m 2L beam is destroying rotato
This post makes me wonder what rotator people with really large 80m Yagi's like W0AIH use? I believe that you want to brake the mast and not the rotator which is not easy to add now. I am told that p
My son's Audi SQ5, had an electrically operated parking brake built in to the caliper. Might be available in other models. You might check the junk yards, or even auto parts stores. Shouldn't be har
How about something like an oil filter wrench. Power a solenoid, or some such thing, to release the pressure when you want to turn it. Maybe another solenoid, with some 'over-center' device to lock
Yagi's Makes me wonder too, since all high power gear trains have backlash. The small PP I had from K7NV showed a surprising amount of backlash, more than Kurt thought it should have. He also commen
How about the DX Engineering RT4500HD. Published spec's are a bit better than the 2800. Not sure if it's enough to make a difference. Rich - N5ZC Yagi's Makes me wonder too, since all high power gear
Any possibility that a flexible coupling of sone sort would solve the problem? Stan, K5GO Sent from my iPhone _______________________________________________ _________________________________________
Yes the larger prop pitch motors have a lower gear ratio but the gear box is larger and considerably heavier so I assume it is stronger. I am not sure if the medium has any more turning torque than t
I do two things here on windy ridge: when the power's off I use relays to put a short circuit across the DC motor in the prop pitches and also the TIC Ring (2-motor). A DC motor with shorted terminal
M2, at one time, did offer the BMW rubber coupling isolation assy, for their OR-2800 rotors. The rubber coupler was sandwiched between 2 x new plates. The 2 x new plates were bolted between the oem d
Searched for the BMW driveshaft damper part - $1200 from BMW with a $500 discount, $31 on ebay. Could there be a quality difference ;) ?? Also, could make one from multiple threaded end (plate/plate)
What is the BMW part number? Will it fit the Orion hole pattern or do you make a mounting plate? John KK9A Searched for the BMW driveshaft damper part - $1200 from BMW with a $500 discount, $31 on eb
I guess emails with attachments just don't make it, so here's a repeat: Here's the story on the flexdisc ("Giubo") isolator: I learned about flexdiscs because my race car used them on the rear (drive
Sorry, it's 26-11-1-229-065, I'd recommend the OEM Febi-Bilstein unit. _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mail

Grant, Mitch here from Alfa Radio Don VE6JY did a lot of experimenting with shock absorbsers when he had has big 80 meter beam. You could something like that. I have made one from a torque disk (repl
