RE: Science Olympiad
Odd but all of this questioning was really geared toware me NOT spending all the money that the hobby requires yet, now that I"ve learned so much, I think I'm going to order a few props, a motor or two and a watt meter and do some experimenting. I'm sure I'll be able to quit whenever I want. My wife is already saying "its rocketry all over again!"......
The instructions for selection of the various components really helped. The selection of the motor is the only problem. I can't find any brushed motor that uses KV or turns in its description but that shouldn't be a problem since most havea "maximum Wattage" rating. I know a bit about electronics but I'm glad you mentioned the voltage sag. I would've missed it and the extra current it allowed.
I'll let you know how it goes.
