HobbyKing® Radjet Ultra 100MPH Airplane 790mm (PNF) (RU Warehouse)

Description

Are you looking for extreme speed right out of the box? If so, we've got you covered. The 100+MPH Radjet Ultra is here!

Extreme speed, easy assembly and wicked good looks, these three things sum up the all new Ultra Radjet PNF airplane! Constructed from durable EPO foam, the Radjet Ultra is one tough airplane, perfect for handling the extreme speeds that this model is capable of. The wing is reinforced with a large carbon fiber wing spar to ensure no flex during high speed flight.

The Radjet Ultra's potent power system is capable of propelling it to speeds up to and even exceeding 100MPH*! This model features an elevon setup with two digital metal gear servos pre-installed. The servos provide plenty of torque keeping the control surfaces in place even at full throttle. Simply put, this PNF model was built for speed!

The included brushless power system can be used with both 3S and 4S lipoly batteries. Two propellers are included in the box, a 5x5 and 4.75x4.75. You will need to use the propeller that matches which battery you will be using. For 4S, use the 4.75x4.75. 5x5 with 3S. Both setups offer excellent performance, however if you are a speed freak looking for true 100+mph speeds, you will want to use the 4S lipoly setup.

Be sure to check out the flight video above. We used the Quanum GPS logger to show just how fast this model can fly!
