I think you have a communication issue. The feedback you’ve received from others is that you communicate ambiguously. You clearly have some technical knowledge. You also undermine your credibility by reaching conclusions presumptively without acknowledging ahead of time that you’re speculating.
An example is when you advised a member it would be a good idea to send their motor to Mark Sutton (Duc Shop) for blueprinting. When asked if you had talked to Mark about that, you refused to answer directly and instead, gave a lecture on engine building. Only after being asked repeatedly, did you finally acknowledge that you had not talked to Mark about it, and didn’t even know if he was recommending that service for the pv4.
... Lots of energy and time into a passive aggressive statement
