Please help. I recently purchased a Giant Lanier Stinger ARF (84") and it has no right thrust built into the fire wall. The manual lays out how to put in 2 degrees of right thrust "if your engine requires it". How do you know if your engine requires it? I plane on using my trusty Zenoah G-62 for power. If anyone out there has Built the kit or ARF please let me know what kind of thrust if any at all you used. Thanks.
