150cc Extra 300SP ARF 

Instruction Manual 

 

 

Congratulations and thank you for purchasing the Performance Aircraft Unlimited 123” Extra 300SP! The Extra 

is arguably one of the most renowne d aerobatic aircraft ever produced. Walter Extra, who designed the original 

Extra, named his aircraft by the horsepower rating of th e motor placed in them. The Extra 300SP is one of the 

newest releases in full scale and now R/C use. 

Our aircraft was designed with 2,694sq inches of wing 

area while keeping the total weight to a m inimum. 

Whether you want an aircraft precise enough to compete in IMAC or 3D until you’re airsick, the PAU Extra fits 

the bill. Its light weight give s you the stability in  high-alpha to take it to the ex tremes of the flight envelope. If 

tumbling maneuvers are your thing, our Extra 300sp will deliv er with picture perfect wa terfalls and blistering  

tip spins that are not for the faint of heart.
