Gypsy, its called "built in continuous profit maker for Uncle Frank" because of the power situation the blades need to be as light as a feather, but in doing this the inards are made of kitchen foil to resemble the home of a Bee, then they put some thicker kitchen foil over the top and stick it down with some strong glue stuff, when it gets hot and/or wet as well thats when chemistry starts to work on it and heyfranko there ya go again another customer damaged blade, ... that'll be £20k thank you.
solution heavy gauge Blades, so that needs more power from the mil, that needs stronger gearbox and bigger elastic bands, that needs a stronger airframe, that needs bigger petrol tank, that needs a bigger wallet !!
where do you stop this sort of problem, ... best go for a different make... but take your bigger wallet!
