You got P. Phil, Buckeye Chuck( Marion Ohio) General Beauregard Lee in GA and a host of others. Phil has been right 37% of the time, So I am going with the General, since he said 6 more weeks.

Right now here in MI, it is snowing, 3-6 inches of lake effect snow till Monday morning, 14 degrees, wind chill of about 4 above and enough snow on the ground to float fly, if you can fly in 14 degree weather.

It is crow season in Michigan, not groundhog season.

there are many groundhog predictors. It is a way to make money. I am sure Indiana has it's own groundhog, but I don't know the name if they have one.

Hi Dag...

Something that might be of interest to you.....CAT6 servo extension modules (send and receive)

I thought so....and I was curious as they were saying that it could be used with a servo controller, I.E. for robotics or something, so, I called them, and was told there would be no problem using them with a receiver.

If you don't need the distance (ie your not building a real plane ) you can likely just wire your servos straight to cat 5/6 cabling. Use a couple of wires for voltage and ground, still leaves 4 for the signals (or run separate power). Actually seems to be what they are doing, just with a level converter to boost signals so they will go 100 feet.

...or, just use the Futaba S-Bus system that only requires a single servo extension to run as many channels as you want.

To this day I've haven't read an explanation of how the S-Bus system handles the electrical load of all those servos. In Giant Scale applications (IMAC for instance) each servo could pull a couple of amps of intermittent load. That, times the number of servos, always struck me as too much to expect from even heavy gauge servo wire over a long run.

Unless Dag has switched, if I remember correctly he is using a JR radio, thus the S-buss system won't work.

Well I haven't used the system, and am no expert in giant scale electronics (so disregard everything I'm about to say! ), but they did make mention in the video above that you can add a remote battery at the tail to provide extra power there if necessary. Just the same, you could run heavier gauge power wire to a distribution back there to feed the main S-Bus hub.

I don't think Dag is going to want the weight of another battery in the tail of this plane, or to have to build a hatch to access it either...

SteveT, just a random thought as I'd read your post. No need for an extra hatch, just build the tailgun as a push-in plug arrangement with some rare-earth magnets to keep it in place.

However, any extra weight any distance behind the CofG will need that much more weight in the front end to balance (Archimedes' principles re levers).

To those in the US celebrating Martin Luther King Day, or those in Canada doing Family Day: have fun!

Hi Steve - I never suggested that Dag do it, as he is already fairly committed with his JR equipment and I'm sure doesn't want to rework things at this late stage. It was merely a general response to pappy35's general question.

It's president's day but we can pretend it's MLK day, that's cool too.
