MP Jet 061BB F1J special.
|
This is a factory tuned MP Jet 061BB. It is fitted with a pressure tapped backplate, remote needle and large bore venturi. It did 21,900 on APC 5.7 x 3 on 5% nitro and 30,100 on 5 x 2 Graupner on 5% nitro. The Aeromodeller engine test estimated 0.32 BHP at 28,000 rpm on 40% nitro. If it can spin an APC 6 x 2 at this speed it would be in the same league as the Shuriken and the Rex-06.

This version was a Doug Galbreath tuned MP Jet 061BB. Modifications included a Nelson plug adapter button, custom needle valve assembly, increased exhaust timing, lightened piston, rebalanced crankshaft, transfer passages machined into crankcase casting and corrected shaft bearing preload. Performance was claimed to be 28,000-29,000 rpm turning an APC 6x2 propeller on 50% nitro, putting the modified engine in the AD-06 league.
A radial mount, pressure feed backplate and spinner nut are standard accessories.
