My gripe is just the fact that it's 'electric.' The Pegasus was a joy to build, and a total riot for the first 20 minutes of owning it. Then, I had to re-charge 'the' battery (with a DC/car plug quick charger), which only took another 20 minutes. I kind of got tired of it after the first 2 hours of playing with it. The Mabuchi RS-240 can and Tamiya 6-cell flat-pack is the equivalent of having a Honda Civic VX (D15Z1) econo-box, when I now own a '71 Mach 1 w/351 Cleveland pushing 400hp (that's why I don't have the Honda anymore, BTW).
That's basically the difference (to me) between my 'cute' little Pegasus and any of my Nitro cars. Once I got the SuperTen assembled and broke-in the stock GT-15 engine, it was such a blast! And after the first tank ran out, all I had to do was flip open the cap, fill the tank, and I was on my way again. I drove the first set of tires off that car the first day I had it. I was hooked on Nitro and will never look back. A buddy of mine gave me the other Pegasus after he bought a Kyosho Nitro Inferno and transferred his radio and servos over. He was MUCH happier.
I'd thought of getting a super-nasty racing motor, full bearings, and replacing the mechanical 'swiper' speed controller with a Novak Rooster I have floating around, but then there's the whole 'gotta get some monster batteries and some kind of a super-charger/maintainer (is Tekin even around anymore?) and spend the time charging & peaking batteries before my limited number of runs (based on how many battery packs I buy/build), and I just can't think of any good reason to do that.
I have much respect for those with the patience to run their electrics, and run them well... but I just never developed the appetite for the care & feeding of the batteries and deciding which motor worked best with each one to get the most power and/or run-time like my buddy Lewis did (stupid fast Yokomo YR-4 with at least a dozen motors and twice as many battery packs). He'd get his strategy figured out on which combination would be the most dominant during our road races (he was a helluva driver, too), and I'd hag all that up just by switching from RedLine 15% to Blue Thunder 20% Nitro. We'd get together on Friday nights in his garage to prep for the next day's fun, while he was charging/peaking the batteries and recording the results from his Tekin charging station and pair with the appropriate motor, I'd mount and 'belt' my tires (with duct tape). He preferred slicks and bought the belted HPI tires, where I would just buy a couple sets of Pro-Line Road Hawgs or Speed Hawgs (which is all that would fit my car, aside from the expensive Kyosho factory tires) and spend an extra 5 minutes per tires applying the duct tape. I guess I was more into the cheap tricks and instant gratification of Nitro.
Still, I'd love nothing more than to have those days back when we'd tear-up parking lots on Saturday mornings.
I'll go sit down now.
