Hey guys,
Have a ys that has developed a knock and no longer runs. Was wondering if there is anyone or anywhere to send these for repair! Thanks in advance

Central Hobbies used to service YS engines, that's where I sent mine.
The web site shows two places that do service but none are in North America.
Cheers Floyd

I have dealt with Nick Verano (I think Nick is his name directly) of YS USA before.
He's from Nevada. very helpful guy.

I too have dealt with YS America in Nevada for parts, but not sure if currently in business.

A quick search shows this source for parts only:

https://www.rcjapan.net/index.php?ma...a7l3372lv4v5e0

What size engine? I built a quartet of 120s, (of different versions) from boxes of bits and still have quite a lot of spare parts.

On that note, can you add some more detail. Along with the "Knock", is there compression, rough turning, etc.?

The Real Jet Jockey · 09-13-2021, 07:20 AM

Compression still seems good as well as the bearings. There is no grinding or hard spots when turning the motor over. I believe it is a 140 with the supercharger. I will get it out of the plane here shortly and have a better look

Thanks for the help so far guys!

Post some pics and anything you find. Maybe some of my spares would be compatible if that would help.

Personally, think that anything worn internally, such as a connecting rod, would not really stop it at least from running. having said that I would recommend having a boo to ensure nothing rattling around inside that can cause irreparable damage.

CK Aero is the new YS distributer for North America. They’ll do service as well.

Yup a quick google works every time so here is the link:

Get a quote first if you can. Central Hobbies was reasonable with the repair costs. I think my service cost was $30.00 plus the parts they used. But when I checked the costs for shipping, parts and service the engine was border line worth fixing.

I figure your shipping alone is going to cost $60.00 back and forth. It might not be worth fixing the engine in the long run.
Cheers Floyd
