A while back, my flying buddy Gary gave me a Balsa USA M-1 Bristol as a thank you for some work I had done on an airplane of his… or maybe it was a few airplanes… or a bunch! Anyway, we had both seen it at a swap meet and I had admired it but he bought it. I think it may have been traded off and then reacquired at some point before it found its way to me but in any case it has been sitting in a corner of the shop for a while now and I finally picked up what I think will be an appropriate power system for it, the E Flite Power 46 and a Castle Creations Talon 90 Speed Controller. The Talon is a bit of overkill but for some reason seems to always be available at a relatively lower price point in the Castle line (my favorites). It has an outstanding BEC capability and can handle up to 6S and 90A. Castle and E Flite are among my favorite brands. The first task was to build up a good engine mount for an airplane that was kit built to mount a glow engine. To mount the motor out far enough to get the back plate beyond the cowl face means spacing out somewhere around 3″ to the back of the motor in this case. Nose weight is also not a consideration since the Bristol is so short nosed and more likely would need more weight up front if anything. Finding some 3″ spacers is difficult at best, and I like the idea of something more rigid anyway (long spacers tend to flex or twist a bit under load). To accomplish this I decided on using some shorter spacers mounting to what I refer to as a sub-firewall and then more short spacers to the X mount on the back of the motor. This assembly is very strong and uses a few easier to find smaller spacers and some rigid plywood to put the motor out where it is needed. Here are some pics showing the assembly.There are a few other necessary installation tasks… servos to be mounted, an arming switch to mount, and making sure the battery can be located in a spot where the plane will balance… but progress is being made. Looking forward to flying.
