Full Description

This model was the last ever free plan to be published in RC Model World magazine (RCMW August 2017). It was designed by John Rutter especially for his Saito FA-40 four-stroke engine, although similar-sized engines will also fit. The sleek nose is also perfect for a brushless motor conversion. For 5 function R/C.
