The port side of the fuselage sports the other elevator and the rudder servos (above). The surface mounts make any adjustments quick and easy. The side force generators (SFG) are easily removable with two screws each (top right), however the author has yet to have a reason to remove them. A detail shot of the landing gear shows the expertly painted wheel pants (at right). Two machine screws hold them securely to the gear.


tude, I trimmed the U-Can-Do SF out. Just a couple clicks of aileron trim were all that was required. The rest of the flight was spent get- ting a feel for the plane, as well as doing pho- to passes with my wife, Jenn, behind the lens. My initial impressions were that the U- Can-Do SF was extremely light in the air and very easy to fly. I first threw some loops and rolls at it, then some flat spins and tum- bles, which it performed with ease. The 65AX, spinning a 13x6 APC prop, provided an excellent power to weight ratio, with un- limited vertical potential on tap. After seven minutes of excitement, I brought the SF in for a safe, slow landing.


As I put a few more flights on the U-Can- Do SF, I quickly realized that it was becom-


ing one of my favorite planes, and that is say- ing something, as I have more than a few. On low rates, it is extremely tame and forgiving. With the rates cranked to the max, it is capa- ble of any extreme 3D maneuver you can think of. It excels at performing rock-solid harriers and the side force generators defi- nitely make a difference here.


With both sticks thrown into the corners, it tumbles better than any other 3D plane I fly. Upright and inverted flat spins are spec- tacular, roll rate is blistering, and knife-edge loops are doable with very little coupling. With its fat, fully symmetrical airfoil, the U- Can-Do SF slows down quickly once the pow- er is pulled back, and floats as if it is a foamy. Don’t be fooled though, the SF is no one-


trick pony. It also excels in the precision and pattern departments too. Just flip to low rates, and crisp point rolls, hammerheads, figure 8s and square loops will have you fly- ing like a pro in no time.


It’s a keeper


Great Planes has been setting the stan- dard for an affordable, pilot-friendly way to break into the 3D flying world for years with the U-Can-Do line. The SF continues and improves this dynasty, adding in even more bang for the buck. Whether you are an inter- mediate pilot looking for a first 3D aerobat, or a seasoned pro seeking to hone your skills, the U-Can-Do SF has something to offer for everyone!


Your author’s patient wife Jennifer models the U-Can-Do SFfor the camera (at left). She picked that scarf specifically to match the plane. The U-Can-Do SFperforms a knife-edge for the camera (above). Note how little rudder is required with the SFGs. Overall, it is an incredibly good flying airplane, no matter what flying style you prefer.
