The battery plate is securely fastened in place under the spruce lip
with socket-head bolts at the back.
Behind the firewall of the 97-inch Ag Wagon is a securely epoxied
spruce stick that acts as the front retention for the battery plate.
bolted into place, the pack will never
accidently come loose and it can be used
in more than one airplane. The plate is
made from 1/8-inch five-ply plywood, not
Old Wives’ Tales
In the “old days,” I used to hear people
say it was great building for electric
power because you could remove all of
the plywood and extra reinforcements.
It is true they don’t need to be built
to withstand the fuel and vibration from
glow/gas engines, but they must be built
to withstand the torque of the power
system and that means proper engineering.
Today’s kits/ARFs come with electric
power in mind and are built light, but
strong. Don’t out-engineer the engineer.
Mentioning my program mix set to
act as a throttle cut/throttle hold for my
airplanes has generated much interest. I’ve
received photos of other radios and mixes
and am nearly ready to publish them.
I could use a couple photos of the
Spektrum DX6i, the DX7 (not 7s),
Hitec, and Futaba t7c or similar. If you’ve
programmed a mix for one of those and it
works, send me a photo and I’ll include it.
I’m targeting the December issue, so time
is a factor.
