Hot Bodies Cyclone – From Stripped to Ripped
I happened across a used carbon fiber Andrew Hillman World Champion edition Cyclone roller in almost perfect condition. I say almost because 90% of the screw heads were stripped and it needed bearing and belt replacements.

Since this outstanding RC has sat patently waiting for something special to happen, I decided to let it see some speeds that many RC’s only dream about. Initial testing of the Mamba Max 7700 A123 3S powered Cyclone went very bad when an old front belted tire blew at 57MPH at mid-throttle and broke the rear blocks and a couple pins. Despite the damage, I still wanted more speed. Sure 7700Kv motor isn’t recommended with the 4S packs like the slim MaxAmps pack I used, but there have been more than a few nuts like myself to go ahead and do it anyway. Although I added a new roomier Cyclone Brushless Motor Mount, I made some extra tweaks on the mount with my Proxxon mini-mill to allow for the extreme 50T/88T gearing.5.JPG (2591391 bytes)

After breakage and belt replacements, I swapped the stock bearings for some Boca Plus Plus Ceramic models for maximum spin. A Spectrum RX/TX set was added to assure high-speed control. I topped it off with a DNA ProtoForm body with wheel wells intact for better aerodynamics and pre balanced high shore Jaco foams to handle the speed. How fast? Let’s just say with the later added Castle BEC and fans on the ESC and motor it easily and6.jpg (166718 bytes) consistently rips way past 70MPH on high speed runs without thermaling. The Cyclone is now a bullet that will outrun all but the most specialized RCs. Drop the gearing and voltage to something normal and that Mamba Max system will easily spin all day at the track.
