I ‘ve been looking at the new E-flite Carbon-Z Cub since it came out late last year.  I was looking for something  electric to have some fun with and this one really fit the bill, with the added bonus of being float ready. So I finally got one.  Look for a build (assembly) log soon.

The E-flite® Carbon-Z® Cub aircraft is the first to offer patented Carbon-Z strength and rigidity in a giant-scale package. Like the full-scale Cub Crafters Carbon Cub SS airplane, this ultra-lightweight model by World Aerobatic Champion Quique Somenzini is astonishingly versatile whether your intention is to cruise gracefully or surprise scale admirers with envelope busting aerobatics. Its Carbon-Z structure has been molded with all the detail you’d expect from a traditional model, but you get the popular benefit of weight savings plus maintenance ease. Despite the size, this giant-scale model disassembles quickly into compact parts you can transport in almost any vehicle.

Based on a platform known for its legendary versatility, the Carbon-Z Cub makes giant scale so simple—now even more RC pilots can go big. Its enormous Tundra wheels tackle just about any terrain you choose to romp from, or you can easily mount the optional Carbon-Z Cub Float Set so no RC adventure boundaries stand in your way. A mechanism is included for towing sailplanes with wingspans as large as 3-meters and there’s even an optional camera mount so you can take one-of-a-kind images from a bird’s eye view. Even if you get carried away, the Carbon-Z structure is easy to repair.

A major part of what makes this giant scale icon so versatile is the control innovation package included as standard equipment such as the digital, metal-gear servos, and slop-free ball-link hardware. Because the included flaps are functional, greater control at low airspeeds is possible in addition to the ability to significantly shorten takeoff and landing distances.

Although this aircraft may look tame, its brushless power system has been specially chosen to offer incredible muscle to take full advantage of its multi-purpose potential. But if the ultimate Carbon-Z Cub experience is what you’re after, then you’ll want to install the extraordinary Spektrum™ AR635 6-channel AS3X® Sport DSMX® receiver (sold separately). An all in one unit, its AS3X System will allow you to experience agility beyond the immensely popular Cub form, deliver enhanced stability and a feeling of control that’s always crisp and natural. The 6-channel aircraft transmitter you choose should at least have adjustable dual rates and expo. For your convenience, the power system and battery compartment can accommodate a wide range of 6S Li-Po configurations.

    Glad you are back to the blog.

    I have flown a number of these, both stock and modified. The are a very good, light weight, scale flying cub. But the flying is dramatically improved by adding 50% aileron differential.


    • electricdan says:

      Thanks Jim, it’s always good to hear from you. I’ll keep in mind the differential (which seems to be a lot) when I have the chance to get some flights in.

      Also, would be interested in your modifications and I assume you’ve got her on floats as well.


      • Jim Feldmann says:


        I do not own one. I went to a float fly in Oregon where there were four of them and two or three guys in my club have them. I have flown them on floats, with stock motor and prop and with a smaller motor. (You do not need a motor larger than stock.) A lot of folks do not like the stock prop. I have flown them with and without differential and with and without aileron/rudder mixing. With flaps and a little headwind it will land at a walk. With a little stronger wind, you do not want to use flaps. It does not like gusty wind, either in the air or on the ground.

        A lot of folks do not like the stock wheels because they are too rigid and have broken the landing gear on oops landings.

        So It seems, from my experience and what the 6 or 7 owners that I know have told me, you might want to replace the prop with an APC (I don’t know what size, but check RCGroups.), replace the wheels with something softer, and you should change out the aileron Y connector with separate extensions so that you can put differential in it. The aileron/rudder mix is up to you. If you like using rudder in turns, don’t bother.

        They also say the blue paint comes off if you look at it wrong. One guy repainted it with better paint and another guy gave it a clear coat.


      • electricdan says:

        Thanks for all the helpful information. The prop some are using to replace the stock one is an APC 15 x 6.

        I have a set of Dubro inflatable tundra tires I might give a try after the maiden.
