Nitroholic Posted December 30, 2014 Share Posted December 30, 2014 Is this the actual square pieces that sit on the ends of the axles? If so...that's not an uncommon problem. They copied the design from FG, and it was a problem with them too. Easy to cure. Get a slightly longer grubscrew to start with. If you look at the tip of the grubscrew, it's slightly conical. This actually reduces the contact area. So what I do is to carefully mark where on the axle the grubscrew contacts. Then...remove the square and carefully drill just the tip of a drill-bit in where the grub sits. This makes a conical pit for the tip of the grubscrew to sit in. Then do up with plenty of threadlock. That means that even if the screw loses bite, the wheel square stays on. Don;t go mad with the drillas you don;t want to go through it and weaken the axle....just make a 'nest' for the screw to settle in. 2 1 Quote Link to comment Share on other sites More sharing options...

flatout! Posted December 30, 2014 Share Posted December 30, 2014 Yes definitely drill it I didn't do it to my yamma buggy, wish I did thou, wow you've got ten tanks through it ? Mines still stud there with no servos or a receiver in it but I'm sure it's still ok only put about 4 tanks if that and the receiver went on me, so i bought a king motors and no problems here Quote Link to comment Share on other sites More sharing options...

peter000 Posted January 3, 2015 Author Share Posted January 3, 2015 Just one more question does any one now if there is any over engines that fit the yama buggy cheers Quote Link to comment Share on other sites More sharing options...
Nitroholic Posted January 3, 2015 Share Posted January 3, 2015 You should be able to fit any CY or Zenoah engine. Also...don't bother with a KM throttle servo. There are plenty of servos to choose from which are better quality and give better performance. Try an Alturn 780 metal geared one or the power HD 1501 Quote Link to comment Share on other sites More sharing options...
flatout! Posted January 6, 2015 Share Posted January 6, 2015 You won't go wrong with advice of these guys matey, and iv got a load of stuff for the yama buggy pal, to full cars worth and they both run fine but no carb and pull start on one but one of them, but the other is bang on and it's had the trottle servo changed and it's quite quick the servo i mean!

macgregor Posted January 11, 2015 Share Posted January 11, 2015 most engines will fit. you just have to mount it correctly. rcmodelz still have some stock of squares to fit the yama. Quote Link to comment Share on other sites More sharing options...
flatout! Posted January 11, 2015 Share Posted January 11, 2015 (edited) I'm thinking of drilling the axel so the grub screw seats it's self in it, iv sat it on the flats and tightened them so tight i can't go no more but the drive side still comes a drifted with red locktite to, it's going to have to be drilled im sure unless the square your on about are a better quality then ill try them, it's a yama buggy i don't think anything on it is any kind of quality lol! But I'm getting theyre with it, iv made it a project to make it better because i believe with some time and effort it will be a strong little buggy, my Mrs is using it at the minute so all good and it's getting used Edited January 11, 2015 by flatout!
