AJ Sun, et al,
The pictures may have mis-led you and other viewers..!!...sorry..... At some point in the distant past, I had covered over the engine cover on top, pending the time I got another engine. For the moment, I just doped it over too, but intend to mount the engine in the normal upright fashion as it originally was, and then cut out for the engine head!.

The mount for my "new" K&B 19 is a different story, as I want to retain the mounting bolts for the K&B 35, but have the option to mount a K&B 29 also, in the event the K&B 19 is not powerful enough for my simple demonstration flights! The engine bolt holes don't line up for the other engine sizes.

My idea is to use short aluminum flat strips (1/16 inch or 1/8 inch) on top of the existing engine "logs". On each side, I will drill 4 holes through the aluminum. The first 2 will fit over the K&B 35 bolts, and allow me to tighten the "flat" down securely with the nuts and washers. The second 2 will be for the K&B 19 bolts sticking upwards. I will drill out a bit of the "logs" for fitting the bolt heads. This will bring the new engine approximately 1 1/8 inches further forward.

I should be able to mount a K&B 29 in the same fashion if wanted, and also have the option to unbolt it at any time and mount a K&B 35! Let me know your thoughts!
