Recently, I bought a nice little 33" profile electric 3D ARF. Also ordered some micro servos as recommended by Tower. Received the kit and manual stated that sub-micros were needed to complete. I sent an email to Tower and they immediately responded. Tower is crediting me for the wrong servos - I do not have to send them back, and they are correcting their website information on that particular model. Awesome service!
A few years ago I had a fuel pump catch fire while fueling up a nitro airplane. I couldn't see the flames, but I could feel the heat. I immediately smothered the fire with a rag. No damages. So, I sent Tower an email regarding the incident, noting that the on-off switch was not isolated from the pump itself. I didn't ask for anything as the fuel pump was 2 years old and out of warranty. Well, Tower shipped me a brand new pump, free of charge! Now that's service!
I've been buying from Tower for 20 years and they've always treated me right. Good products, good prices, on-time shipping - and they back up their stuff (and take care of mistakes)
