Blazing Star DA-60 Standoff - 1 inch (25mm) length with additional 2mm and 3mm Delrin spacers included. 

Blazing star mounts offer a convenient way to make up required mounting distance on your gas engine installations AND provide tremendous extra strength to your gas engine case in the event of a crash. Mount the aluminum blazing star mount directly to the back of your engine and use any necessary plastic spacers between the wood firewall and the blazing star mount. 

NOTE:

This product is designed to mount GP-61 and DA-60 engines to our 50-61CC Extreme Flight aircraft. The GP-61 and DA-60 engines are NOT the same length. The GP-61 is approximately 11-12mm LONGER than the DA-60 (146 vs 134mm). For this reason, our newer 85" series kits include four 11.5mm length aluminum spacers to use with the DA-60 engine to make up the length difference. Place these spacers between the Blazing Star mount and the wooden firewall.
