I have a Tesoro Bandito with the brown 8" coil. I bought a 11" coil off ebay that I
couldn't use so decided to make it work with the Bandito. I got some foam and wire
and wound up a concentric. The TX was low (5.5V) and poor air test depth. My TX
resistance was a bit high so I got some thicker wire and rewound it.
Now I have 8.5V p/p just like the Brown coil and the RX is nicely nulled but I still get
only 7" in an air test. The brown coil tests to 8". I didn't want to change the RX cap
as I want it to work with the brown coil.
When I originally set it up I ran the TX and RX wires separately with shield on it's own
wire and grounded the shield to TX minus in the connector at the control box. After
winding the new TX I tied the shield, TX minus and RX minus together in the coil
like I assume the Brown coil is. I had it sounding when you touched the ground balance
pot with the separate wires but seems good now.
What can I do to increase the air test? I assume it should test the same or a little better
than the 8". Any ideas?
