Prabal,

I've attached the circuit diagram.

You only need to use two out of the three leads of the transformer. Either left and center or right and center (as shown in diagram).

Those are called alligator clips and can be bought at any electronics store. You can also get a lot of nichrome from a 'heater coil' and it costs only  :Rs: 20.

Today might be a great and wonderful day. It depends on you.

A great place to find Nichrome is from fishing leaders. They are the wire leads they use in deep sea fishing. It goes between the hook and a swivel further up the line. It's used to stop big fish from cutting the line.

I purchased just one of them and it has enough Nichrome to build 5 cutters. Mine has been under tension and used for 5 years and it's still as good as new.

i finished the wiring but because s.a 1's are going on i can do nothing.
on 24th: i will order parts for a avispad. going for a bush type plane.(preffered livery below)
after that i am planning to make a hd thermocol plane.(for source of extremely high density thermocol free; contact me!)
for that plane i will cut a clark-y airfoil!
