RE: Four Stroke?
Ya, a two year warranty. I think I will send it back. I placed an order for another. I am too addicted to go without flying untill I get my engine back, lol. I know its sad....
The "knock" is very bad. Bad enough I get comments "Sounds like your engine is about to fly apart."
I usually use 15% fuel. The last gallon I bought was 10%. Although the "knock" was still there and I still had a bear of a time keeping it going, when it was running decent for a couple of flights I didn't notice any less power with the 10% as with the 15%.
I think I have been wasting my money on 15%. Is there supposed to be a noticeable difference?
