So I tried getting my Rovan running over the past holiday weekend and no luck. I could not get it to stay running. It was also 89F and SO humid that I was dying in the heat and just getting all pissed off. Problem is that last time my Rovan ran was back in March when I did my idle break in. What did not occur to me was the carb settings were for temps in the 40's (very rich). The engine would fart then quickly die. I screwed around for an hour attempting to get the engine to stay running (the default needle settings are not correct for my carb for whatever reason. Got really pissed off and just quit.
Today was much better, 80F and comfortable humidity so I could spend some time and get the needles figured out. After adding a fresh spark plug, and setting both needles at 1.75 turns out I was at least able to get the engine to run and STAY running long enough to begin tuning. Long story short LS was too rich, and HS was just about right. Once I had a good tune I began to play, and first was I needed quicker steering . No problem, went into the Flysky parameters and bumped up the steering ratio. Next 30 min was just spent playing around and my takeaway is a big thumbs up on the 36cc's performance. The Rovan engine with the DDM pipe has some really impressive torque. A solid feed of WOT easily causes the rear MadMax road tires to break free even at speed. Drifting through corners is easily done and using the rear brakes to help rear steer is helpful. My brakes are pretty good, but i'll most likely end up stepping up to a front and rear hydraulic system. Top speed ? I don't know yet my parking lot wasn't big enough to max out mph's. Had one rear wheel hub nut come loose, but no other mechanical issues. The stock Rovan gearing seems a tad high for what I want to do, so i'm thinking I might swap out to a lower gear ratio.
