 Hey All, what is the significance of the C-rating of batteries? What would a 4S 2200mah 20C battery do compared to the exact same battery but a 40C instead? Many Thanks, Dan
Read this; it's pretty much the most accurate, complete, and concise explanation of C ratings that I've seen yet. Incidentally, I wrote it

 Oct 04, 2012, 09:13 AM Just here for the pie. Canada, BC, Ashcroft Joined Jun 2011 427 Posts Something that's been missing for me is a table or chart of RC size classes. I see .60 (I'm guessing is gas/nitro engine size, 60cc), 450 size, park flyer, micro, peanut, ultra micro, etc. What do these all mean? How do they relate to the size of a plane? Any links to relevant information would be helpful--even search keywords. Google isn't being much help. Thanks in advance for any help. Cheers! Randall

Micro and ultra micro are just different size of parkflyers. Peanut is usually describing small free flight or rubber band powered airplanes.

 Nov 30, 2012, 09:34 AM Fly it like U stole it Champaign, Il Joined Mar 2008 2,452 Posts No stupid questions if you don't know the answer. PM = Private Message. Its just a forum thing, not RC. Click on the little mail icon under someones name or go to there home page by clicking on there name and scroll down until you have the option to send private message or e-mail. I still can't figure out PLF and VLF? Some form of his kit completeness I think. Maybe PM him and ask. Matt

 Dec 14, 2012, 09:06 AM Registered User Joined Dec 2012 5 Posts I am a beginner to this hobby. I bought Easy Sky Yak-12 (ARF) and it came with the motor mounted in the nose. Only problem I see is that the shaft of the motor is tilting slightly down and to the right. Is this normal. The motor is mounted on a spring loaded plate with 3 screws and the screws can be adjusted to change the angle of the shaft. But I was not sure id the angle was purposely kept to get rid of torque of the motor or something. Please let me know if I should change the motor angle to straigh ahead. --Paul
