Welcome to DLUSA, the stateside home of the world famous DL50 gas powered RC
airplane engine. We're located in Irving, TX (just north of Dallas), and are
dedicated to helping you enjoy this new addition to the field of 50cc
(and now
100cc) engines. Although only in existence since early 2007, this engine has
already rocked the world of RC gas engines. It's low price,
high quality
and exceptional performance have allowed many people to start flying 50cc gas
planes when they never could before. For the same reasons, many can now fly
second and even third planes.
As it's made in
China, its quality and customer support were immediately suspect here in
the US. Nay sayers said there would be no after sale support and
that it would self destruct in short order. Not so! Many customers have given
them a licking and they just keep on ticking. They've been dissected by the best
and only quality components and machining have been found. When a supplier
defect (carburetor high speed circuit) caused problems, free replacements were
quickly dispatched to all who were affected.
On top of that, every engine sold by DLUSA is subjected to an extensive Quality
Control Inspection and any defects found are corrected before shipment to
customers. What does all this mean for you? It means that any problems that an
engine left the factory with, won't reach you unlike ones drop shipped from Hong
Kong or China. It
means you can rest assured we are here to support you after the sale and
that the engine is NOT a "throwaway", but one you'll enjoy for a very long time.
It means that we're just a phone call away if ever you need us.
Since this engine will allow many new people to enter the realm of 50cc gassers, DLUSA is also committed to helping you get started down this new road correctly. We want to make your experience as fun and trouble free as possible, and help you avoid the pitfalls that have affected the "gassers" that have gone before you. See you at the flying field!
