21. The distance from the front face of the motor box to the motor drive washer is 172mm or 6.8 inches
(this is the length of the DLE-61, the longest of the engines recommended). Because the DA-50 is the
recommended motor we have included a set of machined aluminum standoffs to be used in conjunction
with the stock 2.5" standoffs included with the DA-50 to achieve the proper spacing.
22. The following photos show the GP-61 and Xpwr 40 mounted on an 85" airframe. We used a Blazing
Star DA-60 mount for the GP-61 (they share the same mounting pattern) and the full length Blazing Star
XXL Standoff Set to achieve the proper spacing with the Xpwr 40. You may notice we used a hacksaw to
remove 1" from the muffler downpipe to make fitting the cowl easier.
