Hi Dave, I was reading through several posts and noticed that many are about the .63s and bad regulators. Was it just a learning curve? Has the problem been addressed??

I do want to order one, but I'm concerned that as soon as I get it, I'll have to send it in for repair.
If newer engines have had this problem corrected, is there any way to be sure that I'm getting an engine from the new batch (serial number, stamp date???)

Thanks
Shawn

I don't believe there ever was a problem. You should realize that the percentage of people who post here is an average of less than 5% of the total people who buy engines from YS. 5 problem engines out of every 100 we sell is a small number, I'm sure you will agree.

Don't worry about it. Get one and have fun!

Thanks for the vote of confidence Dave. The order is placed

I BOUGHT 4 63s, 4 110`s and 3 140`s including an L FOR MYSELF AND FRIENDS and we are all very happy -just read the adjustment settings well and use the right fuel.

Enjoy
Gerrie

Good Flying!
