My Posts This: Topic Forum | My stock JR tail pitch link broke last week.
I read the posts above and decided to replace it with the Eco 8 part 67715 thinking it would be a stronger part.
I just received the new part today and the pitch plate is more flexible than the stock one. It does have a little web under it but seems weaker than the stock part.
The tail slide ring is metal and has two bearings but the supplied ball is to small and needed to be replaced with a JR ball.
Also, the small ball links do not come with the 67715 so you need to order them (67564) and the 2mm bolts.
Unfortunately the Eco links are too tight for the JR blade grip balls so you will have to resize the Eco links.
This mod is MUCH less expensive than the K&S version so its hard to pass up in favor of just replacing the stock pitch link but I dont think it is the answer to the weak pitch plate.
I have not yet had a problem with the stock tail ring so I'm not sure I really needed a metal one anyway which makes all this extra work a little unnecessary.
My main concern is the weak plate since I have already had this failure which resulted in a bent tail output shaft, ruined hub, broken tail control arm support and a MAH carbon blade with grip whizzing over 60 feet over my fence! I was lucky I didnt have more damage to the helo or me!
I will try this new part and hope for the best but I think we need something better.
