Customer service

I’ve been dealing with Helidirect for quite some time now.
I am not a patient man lol. When I order something I want it now.
Helidirect has always exceeded my expectations with their attention to detail and expeditious delivery.
I’ve never once gotten an email days later saying somethings back ordered or that someone’s dropped the ball. This company is on point and beyond.
Thank you all for your amazing service.

I replaced a 55hz hyper with this engine. I'm finding the breaking in this engine quite joyful. Seems to hold consistent smoke and already makes great power.

I selected this engine for my Aligne TRex 600 Nitros because I wanted plenty of power to being able to handle 3D flying and this is powerful engine with plenty of torque and a very smooth operation. I am very pleased with my purchase.

I put this engine in a Synergy N5c and it was a perfect fit! Easy to install and provides the power I need plus overhead. The engine was easy to break in and tune. I'm a happy custimer!
