While we all would like to see our installations weigh in at 300 lbs - I have not yet seen any credible figures showing that having happened. I think probably that Perry Mick would come the closest when he was flying with no PSRU - just direct drive. While my early inexperence with aircraft design led me to the flawed "...if in doubt, make it stout."" philosphy - I just never realized how quickly an ounce here and an ounce there would quickly add up to 170 lbs overweight - did have 44 lbs of battery, but still heavy. In any case, to make you feel a bit better, here is the breakout of my FWF installation 377 lbs dry and 406 wet.

It came in at around 350 pounds. Add in a 3 blade IVO prop, oil, and coolant and I am at 400 pounds... Needless to say that is not what I was hoping for as Zenith lists their FWF for a wet O360 with a 2 blade metal prop at 400 pounds. What have others come it at for a dry weight for their 13b setups? __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
