Quoted from fanuminski:

Hello - Yes, the 1:48 is the right scale. I bought the Messershmidt on Ebay (Messerschmitt Bf-109G-10 1/48 Model -$35 or so) to replace my crappy stock fighter plane
and added a fighter pilot to the inside and also the lights/guns under the wings that connected to the existing wiring hookup for the stock fighter plane.
the prop I didn't do anything with at this time - so it's stationary
For the biplane, I painted a bit and used some waterslide decals for the correct lettering on top along with the german crosses out of vinyl self stick.
for the prop I bought these on Ebay:
4pcs 716 Coreless Brushed Motor Set 55000RPM 7x16mm + 45mm Propeller CW CCW

and to slow down the speed I bought these resistors on Amazon:
uxcell 10Pcs 330 Ohm Resistor, 5W 5% Tolerance Metal Oxide Film Resistors
amazon.com link »
There is enough room under and inside the nose of the plane to mount and hot glue the motor/prop.
I think I used two resistors in sequence to slow it down enough and those I placed under the playfield when I ran the wiring from the prop down
and hooked it up (currently) to the hurry up light.
hope that helps.
Its just a bit of work - but not too expensive and I like having a working prop.[quoted image][quoted image]
