what size engine should i use?
i have been using electric power for so long that im having a hard time picking an engine. the plane is a cox model 12 that i picked up. had a dla56 layin around so i mounted it but im not so sure that it will have enough power to hover nicely. i live at 4300 msl so i need that taken into consideration. with the dla it weighs in at 18 pounds. thoughts?

RE: what size engine should i use?
I would love to see people buy one of the better engines once in awhile instead of just the cheap ones for them to learn the differences. People only want to see RPM comparisons which mean almost nothing in a true power and torque comparison. In any case, an engine that weighs close to a pound less than anything else in class, even if using RPM as a power comparison, delivers the equivilant of more power through lighter aircraft weights.
In this case there's a lot more difference than that. Same as there would be with an MVVS 58 or a 3w 55. People leave a lot on the table when all they do is shop price.

RE: what size engine should i use?
Being at the altitude Im at here what would be a good test of an engine here to see if its going to cut the mustard? Guess Im thinking along the lines of measuring lbs of thrust versus weight of the plane. Would that be a good way to get an idea? If so what sort of ratio should I be looking for?
