RE: YS 160 v OS 160
Dear Troy Newman,
Thanks for your answer. Firstly, sorry for my English, it is not my native language. I purchased the defective YS engine from Central Hobbies (USA), invoice No. 91799, so, I got the YS P. warranty, is not it ?. I purchased this engine because of the YS “good reputation” and also because the YS operator’s manual said that the engine can run on 15 % nitro. That is not true, the YS engine I bought from Central Hobbies (USA) does not run on 15 % nitro, it only runs on 30 % nitro[/color]. I also tried 20% nitro fuel (more expensive) but the engine did not like it, I got bad idle and bad mid range transition. Trying to fly my model with this YS engine on 15% nitro I had several dead stick landings before I had a fatal accident, I lost my plane. The 30 % nitro fuel is extremely costly in my country, so, I wanted an engine that can run on 15 % nitro. I read the YS operator’s manual before purchasing the engine, I trusted to YS, I got the engine, now I feel deceived !. Well, I sent the engine back to repair to YS P., I had to pay the shipping charges to the USA and then back again to Caracas, it was costly. I received the “repaired” engine back from YS P. as bad as I sent it, the defective YS engine did not run on 15 % nitro, again. Then, I contacted YS P. by e-mail, I was answered by Dave that: “…..The only thing required on your engine was a piston modification… “ (some small holes were opened in the piston to ensure proper fit of the ring to the sleeve). Can you imagine it ?, a brand new engine needs to be modified by the seller in order to intend it to run ?. That is crazy !!. I paid to YS for an engine and, after sale, they are “experimenting” on it!!. Is that a honest business ? . No, it is a fraud !!. One more time, that is crazy!. YS took my money and gave me a problem instead a satisfaction!. On top of that, I never received an answer from “Mr.” Verano to my e-mails when claiming because of the defective engine and the bad service. I sent several e-mails to him but it seemed to “Mr.” Verano that Caracas is too far from Gardnerville to give proper after sale service to such a “distant” client ! He did not honor the warranty for my engine. “Mr.” Verano never assumed his responsibility for my defective engine and his bad service. I think that, In spite of I am not an USA customer, my money is as valuable as the money of an USA customer. If I were a USA client (citizen), most probably I would not had suffered such a discrimination !
I do not want to be ironic but I have to say that, to be honest, Yamada Mfg. should rewrite their operator’s manual as: some YS engines might run on 15-20 % nitro, most of them only run on 30 %.This four stroke YS engine has been the most expensive and frustrating engine I have had in my life !. I am flying models since 1973, that is 34 years. I was a YS engines user for a long time, had various of the two stroke engines. I purchased my first YS (along with a JR radio) from Circus Hobbies, do you remember them ?.
I have never had such a problem with a OS engine. I have to repeat that I do not recommend YS engines anymore because, in my personal opinion, they are not reliable and mainly because the after sell support is extremely bad. To me, the OS 160 is by far a better option than any YS engine. Actually, I am about to start running a brand new MINTOR 170 engine on an Impact plane. Still waiting for the announced OS 200, but YS, never, never again in my life!
