james,
thanks for the post great to hear it flies so well with stock set up. are you flying from hard surface or grass ? or hand launching it ? as i said i have a belt drive unit i might like to try just to see what difference it makes in flight times and performance. the belt drive i have is from hobby lobby and still uses a speed 600 motor. here is the link to it if anyone is interested. it is a 2.3:1 olympus belt drive,so i will be trying a 12x6 prop and the stock 12x10 and see what my astro flight watt meter says
