VVRC 40 Twin

So....I have a VVRC 40 twin, generation 2, that I purchased a few months ago to go on an EF 74Ē Laser. I was speaking to a very repeatable RC business insider several days ago and he has about talked me out of using it. He wasnít bashing Valley View and spoke highly of their customer service. I know that the early engines did have some issues with the crankshaft but from my understanding these have been corrected. I REALLY want to use this engine but am concerned about the reliability of it. Iím sure I would have great customer service if I experienced issues with the engine but donít want to lose a plane in the process.
Anyone have first hand experience with this engine? Just looking for some reassurance before I put it in the air.....TIA

Well, FWIW........there certainly are a "LOT" of them in the air......I personally would not pass on a great engine, simply based on what one person might have to say......having said that, it also means recommended oil ratio & proper tuning.......again, FWIW

I have 3 of these engines. They run GREAT! I've got them in Slick's, Edge's and Extra's. They replaced the 33'sand 35's that were in there before, Should have done it along time ago...lol!

This is the kind of reassurance Iím looking for. I really really want this to be a good engine, love the idea of a smooth running 35cc class twin.

I would not hesitate to put one in any suitable plane. That being said, I’d make sure my engine was running well and that my installation included baffling, but I’d do that with any engine.

Flew mine today, it's about 5months old, over 3 gallons through it not a hint if any kind of problems. The only draw back I had with it was. The first 3/4 gallon of gas +-, starting it by hand was out, used a starter. Now with more time on it, hand starts no problem. Very smooth running twin.
Now when you want to move up, their (valley View) 70cc twin is very nice also.

I have seen 2 broken cranks within the last 3 months. The latest was the new version.

Mine is almost 4 years old. Just had it overhauled and updated the crankshaft and case. It is great engine.

Mine does not have the CNC crank case like the one in post #9, looks nice. When did they stop using a CNC case?

This is what I was warned about.

That is part of the upgrade to the original V1 engine now referred to as the "Classic"
