Arriving this week, Evolution's new gas airplane engines. We'll have the 10GX (10cc), the 15GX (15cc), and 20GX (20cc). Ounce-for-ounce, every Evolution gas engine is stronger and runs smoother than just about everything else in its class. All benefit from superior Evolution porting technology, Walbro carburetors and ball bearing supported crankshafts. And their sophisticated electronic ignition systems give you the flexibility of powering them with standard Ni-Cd, NiMH or 2S Li-Po battery packs; no regulators are required. No more expensive nitro, clean up times are reduced (except during break-in, the GX engines can be a bit messy), and they use the same mounting options as most nitro engines. Stop in at the shop and check 'em out, or check them out at Evolution's site here.
