But the thing is you can easily bore/stroke or even due both to a gasoline engine to get the equivelent power output, and have an engine that will run on that gas for upwards for 45 mins when that brushless 8hp motor you will prolly have run time's barely reaching the double digits. Plus I can just see that esc becomeing so hot or the batteries themselves over heating because of the amp draw that motor needs. You have to factor in those thing's. Remember the old say "Things that Seem to Good to be True Usually are", this kinda seem like on of those type things.
