the prop i was given with this airplane has a tiny knick in it. its about a quarter inch by quarter inch are that took maybe 1 layer off the back of the prop(its still intact, just a little thin in that spot). it may not even realy be that big........

will it be ok to use it to crank my engine up with? ive broken in and tuned glow engines before, just never on a plane. i was thinking about trying to tune it and run a tank of fuel through it later this morning.
