Nitro RC racing on a budget Part 2 

I don’t know anything about the racing scene but I used to love rc cars growing up! Back in the 80’s the Tamiya kits were legendary. Having one usually meant you had an uncle or grandparent that could help you put it together. A few of my friends had Tamiya kits. One had The Grasshopper and my cousin eventually got Blackfoot. There were tons of local hobby shops back then where you could get everything you needed. One shop catered exclusively to RC enthusiasts and they had EVERYTHING. I miss those days. What I’m watching in this video looks like RC racing on rocket fuel! Lol

7:47 Holy shit, that boy damn scootin' down the front stretch lol

Get a polishing wheel on a Dremel and polish out the idle screw and channel. Polish it all out. Don't use strong abrasive just a soft wheel with little polishing compound.

You've probably already figured this out by now but I just found your channel and I'm burning through it. I had something very similar happen to my SH engine last month (and they likely make the Dynamite engine as well). I was doing the same method as you regarding using elastic hair bands as a fail safe throttle return by replacing the grub screw of the throttle linkage with a longer screw to hook the band onto. What I figured out was that ^that^ caused it to be pulling the throttle slide closed, but doing so in a way that imparted an angle on the slide against the inner bore of the carb where it resides. This happens because the servo pulls the ball end one way, where the band on the screw pulls the opposite direction at the opposite end of the slide linkage. When everything was new, it was no issue as the slide was held so concentric to the carb that it couldn't snag or jam. But after 6 gallons, it finally started to bite in a bit. I fixed it by simply switching to hooking the hairbands around the ball, where the servo linkage snaps onto. Doesn't cause it to come unsnapped, and removes the moment arm bending loading from the slide. Back to smooth as butter w/o buying or replacing anything.

Your carb wore off cause it was on angle, you have to align carb straight as possible to throttle rod, and once you mount it you have feel by hand that it moves freely

Budget, right up my alley. Im gathering up the goods for a budget car. I have a preowned hb 818 i think, cheap ali express pipe, and ordered a sh ps2010xbhcp. Im hoping its a good engine? I might buiild my own starter box. What servos are you running? I have a bunch of airplane fuel to use up but will try it in my hyper 7 first. All i know about nitro is you dont want the slightest airleak anywhere, intake or exhaust!

That’s a bummer you dealt with so many different problems my first sh would get stuck at tdc often even after a gallon and a half

whats the redwbeel on your flysky

What did the retaining screw look like?

Nitro by me is $65 a gal
