Megamodels become UK Agents for AvioMac large model engines

Aviomac specialises in large model aircraft engines suitable for giant-scale aircraft. The company has been making large model engines
for over 25 years. Thanks to the 3-D CAD/CAM designs, the careful choice of raw materials used and high quality CNC machining capabilities, we can really say that Aviomac engines are an excellent choice for model makers. The range runs from 35cc single-cylinder to 240cc six cylinder boxer, with plans for a 500cc twin in 2004. Megamodels pioneered high capacity petrol engines in the late 1970’s with their Lancaster powered by four 60cc petrol engines, and have watched developments closely ever since

Cylinder heads being manufactured at the AvioMac factory

The whole range is covered by a 3-Year warranty, and full spares back up is available. All crankshafts are machined from
solid steel stock, and all ballraces are aerospace grade. All the engines from 70 cc upward use dual-ring pistons to improve the life
of the engines. Well proven Walbro carburettors are used throughout the range. All the multi-cylinder engines have a choice of
magneto ignition with Easy -Start or Solid-state electronic ignition for the easiest starting large engines around.
