Im I just being picky

[bristol188]

Some advice please, I feel that the resistors in these two schematics are not
required or am I just being dumb. They are 10k and 10r which I take as 10000ohm
& 100ohm respectively. The power for both is coming from a bec (battery eliminator circuit) which means you can use just the one battery for power and radio in a model
electric plane or whatever. The 5vdc is already as smooth as a babes bum, I think! Do they perform some function other than current limiting? The Mosfets can take upto 20v on their gate and the control is coming from a Micropic.

I must have done somthing wrong! ah well blame it on-----

10r is a resistor with 10 ohms, not 100 ohms.

Without seeing the pic I am not totally sure what you are saying, but I assume it is a pull-up resistor so that the MOSFET gate isn't left floating. When they are floating they can be rather unpredictable.

Yes thats it I jumped in with a post to quick. Lesson use brain before
keyboard! and I did mean 10r on that resistor, small mistakes can lead to
big stuffups. The pics were uploaded i dont Know what happend I won't try
again. Thanks
