RE: Change of pace.
Busy yesterday, shopping for a reciever & tiny wheels, downloaded & printed a plan,
dug out some servos, park flyer control horns, canopy & carbon tubes for pushrods.
I promised myself to finish my last project before starting another one but the Roaring 20
is so small it won't disrupt things too much.
I really should mix some fuel & give the engine a run. The mix I've found is:
Castor oil - 10%
Coolpower Synthetic oil - 10%
Nitro - 15%
Methanol - 65%
Should that be ok?
Mike, this is the voltage reg I use, just 3 parts, the chip & 2 tantalium capacitors.
I have used it on 3 cell lipo packs but it can probably handle much higher voltages.
Excuse the drawing, it was done on some default program on my laptop.
I usually make an aluminium bracket to mount it to the model & this acts as a heatsink
but it doesn't have to be very big. The higher the voltage of the large battery the harder
the reg would have to work & the more heat it would have to dissipate but from 7.4 volts
to 5 volts is a very small step. Keep in mind also, the more servos the greater current &
more heat. You should be fine driving 4 average servos & a reciever. - John.
