Thank you very much for the advice. I really appreciate it. I did not know about this. I will replace the propeller with a fiberglass one.
Very interesting......I have not thought about it although it makes sense. I am quite new in this field.
Master Airscrew Nylon props work pretty well although NEED to be balanced. If they get knicked a little bit, sand it down, rebalance and keep running it. APC props are balanced better off the shelf (still should be balanced), and are a little more efficient/quieter but are more expensive and if it gets knicked it should be replaced. APC are composite props.
I'm still new to this field, too. I scratch built 1 flatbottom boat so far and am still trying to figure out how to drive it... LoL.. Its a blast to run, and gives ya something different to do. (I normally run 1/8 MT and 1/10 ST r/c trucks so this is waaaay new to me)
