GregHurst Posted November 27, 2011 Share Posted November 27, 2011 After some help, trying to start my Vapor pro with RB S5 engine using starter box , but it just doesn't seem to engage the flywheel enough. Don't think the starter wheel is over worn but it might be. But both engine, flywheel and starter box are second hand. Should the flywheel have teeth on the edge as it is quite smooth on mine and looks as if it might be worn. Any suggestions? Quote Link to comment Share on other sites More sharing options...
kingscott Posted November 27, 2011 Share Posted November 27, 2011 (edited) Hi I have a RB B9 and had a similar problem on a SMD starter box, I fitted a new starter wheel ( Edited November 27, 2011 by kingscott Quote Link to comment Share on other sites More sharing options...
GregHurst Posted November 27, 2011 Author Share Posted November 27, 2011 I have tried adjusting it, but can not get any better contact, fine lining it up just cant get it to lower enough or raise the starter wheel. Any suggestions on a flywheel? What size should the starter wheel be, ie its diameter so I can check if it is worn or not. Quote Link to comment Share on other sites More sharing options...
kingscott Posted November 27, 2011 Share Posted November 27, 2011 (edited) Ha ha I had the same problem, I lowered it that much I hit the drive belt with the top deck!!!! I have no idea of the diameter for you box but obviously there must be a wear issue if you cant reach it very well. Any Idea what make your starter box is? If not post a pic and I'm sure I/someone can tell you As for the flywheel most Nitro engines are much the same besides some are 2 pin and some are 3 pin for the clutch shoes , I can recommend www.answer-rc.com or Apex models, fire them an e mail. Yours will probs be a 3 pin! Answer RC defo stock them, and they look sexy! about 7 quid, you may wish to fire a set of new shoes in there a whilst you have the clutch apart. (age depending) they are about 8 quid for a set. Edited November 27, 2011 by kingscott Quote Link to comment Share on other sites More sharing options...
GregHurst Posted November 27, 2011 Author Share Posted November 27, 2011 (edited) Thanks for that, Not sure on the exact make of the starter box, but I will put a pic up if I can - Here it is. I am also hitting the drive belt and it is at this point when I just start to get contact with the flywheel but not enough!

dazj10 Posted November 27, 2011 Share Posted November 27, 2011 Find a bigger flywheel mate, I've had the same trouble a couple of times, and each time had to get a flywheel with a bigger diameter, I got them from eBay seller ...

GregHurst Posted November 27, 2011 Author Share Posted November 27, 2011 The one currently fitted is 34mm with no grip, how does size effect performance? Quote Link to comment Share on other sites More sharing options...
kingscott Posted November 27, 2011 Share Posted November 27, 2011 Not much is the simple answer! infact I'm sure you wont notice. Humm 34mm is not a small one then, I would go with the 35mm flywheel. http://www.apexmodels.com/gbu0-prodshow/ANSCS4001.html Again please contact them before ordering just to be sure Check this website is superb: http://www.twf8.ws/new/tech/clutch/clutches-index.html#flywheel size Cheers Adam Quote Link to comment Share on other sites More sharing options...
