Hi

Motocalc is no good if you don´t know what to put in...

Try a Hacker B50 11S 6,7:1 on 12x2600 Sanyo swinging...say a 16x10 or 17x12.

this setup would give you lot´s of power, and nice cruiceing at very low throttle.

Daniel,

For a 5lb plane you would need about 10lb thrust. even here the B5011S 6,7:1 would be a very good setup. useing 12cells and a 18x8/10 prop. or go for the classic Diablotin setup, B50 13S 6,7:1 18x10 and 14cells, 2600Sanyo HR ot GP3300.

hope this helps =)
