The TufFlight 4D is the ultimate 3D plane. It does all the 3D moves, PLUS IT's DURABLE! No worries in learning to fly like the big boys.

4D = 3D + Durability
Durability saves you TIME

It's simple and it's the truth.

What is 3D?

Performing 3D aerobatics is flying beyond the stall of the wing using thrust vectoring and the power of your motor to hold the plane in the air, NOT the wing.

Strange things happen when a plane enters the "post stall regime", or 3D realm. An aft CG actually makes the plane easier to control! You find yourself flying your plane so it acts like a helicopter. You see how slow and low you can fly instead of how fast or high. Practice becomes really FUN, and you amaze yourself and friends by doing "impossible" things using very little altitude and airspace. Your left thumb becomes more important than you had imagined possible in the days when you formerly flew only circles, loops and rolls.

Joe and Mark have been practiceing 3D moves on their RealFlight sims and designed a 3D plane that stands up to repeated "dirt naps" typical in learning to fly 3D low and close. The result is spectacular, and helps speed learning of harriers, waterfalls, and the signature holy grail of all 3D moves - the hovering torque roll. You gotta know how to use the rudder to get there, and this plane will take you all the way.

We searched for a name to mimic the "space bar" on your computer for instantly restarting the flight sim after a crash, because this plane does pretty much the same thing -- it saves you TIME, so you don't need to pick up the pieces and go home after a mistake. So we thought of "4D" - 3D plus and extra "D" for Durability to let you Master Space AND TIME !

Never before has the world seen this degree of performance and crashability in a full house 40 size knock your socks off 3D performance package.

If you're a profile fun fly airplane fan, but get a bit nervous about flying your balsa ship too low and crazy, then this is the plane for you. At 4.5 lbs with a Saito 72 and APC 14 x 4W, it's simply incredible and gives you immediate recovery capability from all flight attitudes. A TufFlight 4D with an OS 46 FX and Tower tuned muffler spinning a Master Airscrew 11x4, is the perfect combination for learning 3D down low where you can see what you're doing and progress the fastest.

The 4D employs the trademark TufFlight break away engine mount and durable shock absorbing EPP wing. These protect the radio compoments and allow easy field service of all typical 3D practice crashes.

New innovations for this plane are durable plastic fuselage and FULL FLYING stabilizers. Both "rudder" and "elevator" move as a single piece and don't need hingeing! Plus, our innovative pull pull aileron design gives very durable, slop-free and serviceable hinges. They install easily and survive countless cartwheels, botched harrier landings and engine failures which tend to drop the plane on the tail and aileron tips.

All parts feature flexible or sacrificial crash-forgiving mountings, and easily remove for service. As a bonus, the fuselage tail assembly, dorsal and pectoral fins and landing gear remove in minutes for easy storage or travel.

Use Radical or mild throws as you like, but for full 3D, you need 45+ degrees on both rudder and elevator. More can be better, and this plane will help you experiment to test the limits.

We give you the perfect 3D machine. The rest is up to you.
