Cox Sky Ranger Micro Trainer Review


Most micros are durable due simply to their lack of mass. Not the case with the Cox Sky Ranger micro trainer. Made of super tough FlightFlex™ foam, this is the kind of “tough” that could handle a 1 year old’s teething fit (almost) and still fly. No, this is not safe for a 1 year old…anyway, on with the review!

Intro and Flight Footage
5X5 Review Scoring



Hard to sum up in just a few words (watch the review video to get the whole picture), the Sky Ranger is tough, plenty powerful, flies great with power on, glides not-so-good, and is best hand launched and belly landed with the gear removed.

This is the truly affordable, durable, first time micro trainer. You’ll spend more time in the air than you will repairing or fiddling with the Sky Ranger so your cost of ownership is of the lowest in the business. The run-times are good and the stability is trainer-class. No, it’s not the precision you’ll eventually want as your skills improve, but it’s always better to learn in an old ’69 Ford LTD four-door tank than a little Mazda Miata, right? The Sky Ranger will help you build good, basic flight habits and provide many, many hours of fun!

    Thanks for the recommendation, fellas! The Sky Ranger was the first plane I put in the air…had 2 of them, in fact. Flew the wings off every sunrise and sunset for a week…great little plane in very calm weather for the newbie pilot whose palms get sweaty and knees shake a little ( like me). Literally burned both planes up learning how to keep them in the air. Great review, guys! Thanks!

    I am looking to buy an RC plane, and I was just wondering if this one is three channel (ailerons, throttle, elevators) or two channel?

    • avatar Kurt Gornek says:

      The Cox Sky Ranger is a three channel airplane. To clarify though, it has Rudder, Elevator, and Throttle. The main wing dihedral causes you to bank (turn) when rudder is applied. This is the typical 3 channel configuration. Good Luck!

    thanks for the help :)

    P.S. do you know of any three channel airplanes (ailerons, throttle, elevators) because a friend has both kinds and I found the one with ailerons easier to fly

    thanks again :)

    Does anyone know if there are alternate batteries that can be used on the Sky Ranger? Or is it only compatible with cox 2s 180mah battery that is provided? Would an e-flite 2s 180mah battery work? Thanks for any suggestions.
