Title: Futaba servo mounting Post by: realm wrecker on July 13, 2010, 03:54:45 PM Hey guys,
I'm building my own trainer from a kit (Thunder Tiger Ready MK3) and have run into some confusion wrt servo mounting on the servo tray. Please help me out here. Here goes the problem description: While mounting the servo on to the wing, i drilled holes (2mm) thru the servo rails and fit the aileron servo there. However, later, on reading the Futaba manual, i realised, i was supposed to use the brass eyelet and rubber grommet between the servo and railing (since servo has to be insulated from vibration ) . So i started off to do this and realised the grommet/eyelet pair wouldn't fit inside the 2 mm hole and needed a bgger hole and thus expanded it to 3-3.2 mm hole. However, now i realise it was a mistake, coz the screws provided with futaba are much smaller than the hole. :( I can remedy this by adjusting some nut bolt pair to the servo mount. But i want to know where i went wrong. How exactly does one accomodate both grommet-eyelet fitting (which needs a 3mm hole) and the mounting hole on the servo itself (2mm) at the same time? :headscratch: Title: Re: Futaba servo mounting Post by: anwar on July 13, 2010, 04:54:11 PM You need washers, which are provided, I believe.
The picture in the thread below should give you a fair idea of how this works. http://www.rcuniverse.com/forum/m_8336917/anchors_8338635/mpage_1/key_/anchor/tm.htm#8338635 The metal eyelet goes at the bottom (see this thread). http://www.rcuniverse.com/forum/m_1297852/anchors_1297852/mpage_1/key_/anchor/tm.htm#1297852 Title: Re: Futaba servo mounting Post by: realm wrecker on July 13, 2010, 08:49:34 PM Perfect ! thank you so much Anwar. Helpful as ever (and quick too) :bow:
I'd been looking at it upside down all along :banghead:. And now when i read the manual again, it seems so obvious.....so much for not making silly mistakes |
