Actually I am using the converted glow P51. I am powering it with a cobalt 400 with a 3:1 gear box. I am using 8 2/3a nicads to start with. The are rated at 800mah. The static thrust on this set up is 20oz and 7A. I have not run a long duration test because I lost the set screw on the prop holder. I am also having 8 cell 700mah packs made. I will be getting 50 of them so some will be for sale for around $12.
Here is the P51 in construction
