From passion to professional manufacturing

Model maker since 1985 and jet pilot since 1998, the founder of CMJets began producing custom fuel tanks to meet the needs of his own aircraft and those of close friends. Step by step, this personal work evolved into a professional activity in 2014.

Since then, CMJETS has supplied fuel tanks for well-known manufacturers and brands such as João Matos RC, Jet Model Factory, Pirotti Models, SebArt, and others within the jet aviation community.

Custom fuel solutions built for real aircraft

Discover our tanks

CMJETS designs and manufactures Kevlar fuel tanks for gas engine models, glow models, turbine jets, and UAVs. Both serial and fully custom solutions are available, always focused on fit, durability, and performance.

All Kevlar tanks are made to order. We usually do not keep tanks in stock, as customers can personalize their tanks with names or logos, creating a truly exclusive product for their aircraft.

Standard manufacturing time is approximately one week. For custom tanks, customers can contact us by email and provide 2D or 3D plans with dimensions.
