Tonight I got my new DL 50 mounted on my new Goldberg Extra 330 that I found online from Graves RC in Florida. I bought the last Goldberg Extra 330 I could find online as well as a Goldberg Edge 540. Both planes are 77" . I plan on mounting a DL50 on the Edge next. I had lost my first Goldberg Extra 330 three weeks ago when my "buddy" crashed it by pile driving it into the runway. Post-mortem found that we had lost power to the Spectrum AR7000. Must have had a bad battery or broke a connection as he was churning the sky. Plane was a total loss as the motor was 8 inches in the dirt. The old-style aluminum mounts were mangled and one of the mounting ears broke off the engine casting. Muffler was also crushed. Although I did save all the electronicsall servos and receiver. Still I'm worried that the motor bearings or shaft may be damaged. It's currently with Bob at DLUSA for an estimate of repairs.

Because I'm impatient, I had him send me a new DL50. This time I'm using dual batteries on a Smart-Fly PowerExpander with voltage regulator to a JR R921 receiver with four antennas. Talk about redundency!

Unfortunately, I just now found that my new Vess 22B prop won't fit because the the stock prop bolts are not long enough to fit through the thicker Vess prop.

Two questions. Does anyone know what size these four prop bolts are? They appear to be metric because none of my standard cap head bolts match. Also, I plan on running the engine tomorrow, but I have a gallon of 32:1 gas already mixed with Ryobi 4-stroke oil that I use on my Quadra 52 in my Giant Aeromaster. That gas/oil mixture seems to work fine on the Quadra. I do have some Lawnboy smokeless, but didn't want to (nor know where to) dispose of the gas I have already mixed. Do you think it will be a problem to use the Ryobi for the first gallon of break-in on the DL50.
