Not wishing to contradict others, but I think 70W/lb is plenty for your relatively lightly loaded, high-lift sectioned model, providing the prop diameter is reasonable and the grass isn't too long. My 30lb Super Cub leaps into the air on <70W/lb. Go for 100W only if you want a healthy safety margin of power, but either move up to 8s+ or if sticking with 6s remember the batteries/ESC/motor will have to deal with 100A.mick a wrote:thankyou very much gents

as im a nitro dinosour so understand that bit
is it around 100 w per lb i need ?
