christopher small Posted May 26, 2016 Author Share Posted May 26, 2016 I think someone has changed the gears.it seems to be a 4f spline and not the 3f as found on 148 ,3003 etc Quote Link to comment Share on other sites More sharing options...
CARPERFECT Posted May 27, 2016 Share Posted May 27, 2016 Is it a genuine Futaba servo ? Ebay is full of copies , Do not ask how i know. And they have a different spline Quote Link to comment Share on other sites More sharing options...
CARPERFECT Posted May 27, 2016 Share Posted May 27, 2016 Futaba 3003`s for less than £4 ? std price £9.00 Genuine ones have a black spline coming out of then not white. just looked 4 for £13.20 Quote Link to comment Share on other sites More sharing options...
