Ross Clarkson Posted January 22, 2010 Share Posted January 22, 2010 Hello, Why do we use the type of throttle linkage at the servo end that we do?What i mean is, the type were there is a small metal adapter on top of the servo arm and then the throttle rod goes through a little hole in this adapter and is secured with a grub screw. I have just fitted mine and it occurred to me, that if that grub screw loosened at full or even half throttle it is game over!!!! Why don't we use a more secure method? Really interested to hear your thoughts. Quote Link to comment Share on other sites More sharing options...
Rob Posted January 22, 2010 Share Posted January 22, 2010 I use a z bend on the carb end of the link and a metal clevis on the other,has never let me down yet but still allows for adjustment. The way i look at all linkages is to keep them as short ,simple and sucure as possible the less joints etc in the link the less there is to go wrong.

James40 Posted January 22, 2010 Share Posted January 22, 2010 I'm not sure what you mean Ross, have you a picture ? I've put ball joints on my P-51, they take up slighty off angles and any slop in the linkage nicely.

Dusty Posted January 22, 2010 Share Posted January 22, 2010 Ross do you mean a EZ connector? many other ways to attatch the throttle to the servo/linkage. Will find a link for you to keep you busy while people post their methods! Quote Link to comment Share on other sites More sharing options...

Ross Clarkson Posted January 22, 2010 Author Share Posted January 22, 2010 Awesome Dusty, cheers. Yes, it is an EZ connector but i will be changing it now. What way do you do it? James, where did you get your ball joints? Quote Link to comment Share on other sites More sharing options...
Ross Clarkson Posted January 22, 2010 Author Share Posted January 22, 2010 Ok, i have decided i want to change my throttle linkage. Unfortunately this will mean getting a new push-pull rod as mine is not threaded at any end. Can anybody link me somewhere i can purchase these? Wish i had a LMS near me!!!

James40 Posted January 23, 2010 Share Posted January 23, 2010 You can get them from any online stores or pop into Swindon Model Shop, it's not too far away and they have a selection of pushrods. I only fitted the ball joints because I wasn't happy with the quality of the clevises and pushrods that came in the kit. I replaced them with carbon rods, ball joints or metal clevises. Carbon is a nice material to make pushrods out of, it's easy to cut to size, easy to epoxy whatever fitting you like on the end, it has a huge amount of flex for taking up angles where metal would have to be bent and it's light weight.

Ross Clarkson Posted January 23, 2010 Author Share Posted January 23, 2010 Aaaaah, that sounds good James.Carbon rods with fittings epoxied on the end, cheers. Totally forgot about Swindon! Going online to check it out. Quote Link to comment Share on other sites More sharing options...
Bruce Richards Posted January 23, 2010 Share Posted January 23, 2010 Ross when you say "game over" if the throttle comes loose. I don't agree I had the throttle jam on several models (never due to these connectors though) and I have just flown around until the fuel runs out then landed dead stick. Never damaged a model because of a stuck/slipping throttle linkage. Quote Link to comment Share on other sites More sharing options...
Ross Clarkson Posted January 23, 2010 Author Share Posted January 23, 2010 Fair point Bruce, i didn't think of that. That would be one hell of a flight though if it happened at full throttle just after take off!! ha ha Quote Link to comment Share on other sites More sharing options...
Bruce Richards Posted January 23, 2010 Share Posted January 23, 2010 Yes I would not want to do it on a clod day like today my hands would be dropping off. But it does give you a chance to pass the TX around among your flying buddies. Quote Link to comment Share on other sites More sharing options...
kc Posted January 23, 2010 Share Posted January 23, 2010 Surely it's about time engine makers fitted a servo instead of a throttle arm so that we could just plug it in instead of having rods, cables or having to adjust the throw. Somebody must have thought of this before.......is it patented? Or should I have patented it before posting this! Quote Link to comment Share on other sites More sharing options...

Next you'll be saying my idea for a bagless vacuum cleaner should have been patented Ross, not sure if Swindon have carbon rods but I've got about 5 meters of 2mm and a meter of 1.5mm if you need some. Just let me know and I'll drop some round or meet you at the model club on base. Quote Link to comment Share on other sites More sharing options...
