There was room and I had additional batteries on board . Not a thing wrong with spin on props,
15" on I1?
how much clearance was there between the prop and plastic nose piece, zero?
Why in the world, (given the choice this time), would you go back to self tightening/spin on props? (because of the "time" it takes to install 8 screws??) That's nutz and misinformation!
You clearly have no idea how long it takes to screw in the 8 little screws, so I'll tell you.
It takes less than 10 seconds to leisurely screw in 2 screws. (more like 6)
Times four motors, you are at 40 seconds total.
If you are really old and slow, and you were give an additional 20 seconds, now you have 1 whole minute.
Taking 1 additional minute to "securely" fix the props to the motor is NOT time consuming, and in NO WAY should be used as an excuse or deterrent from using bolt on adaptors.
You're gonna be flying in the wind some day, and when you come to an abrupt stop, one of them props are bound to spin off. It's not a matter of "if" it'll happen, it's a matter of "when" it's gonna happen. I absolutely could not sleep at night knowing that I have spin on props with no locks on my expensive I2.
Lastly, it is human nature, (no matter what he subject), to knock the other options.
It's a knee-jerk reaction to "justify" your choice to others.
Just please don't choose spin-offs because it takes "too much time" to screw in 8 screws, (because it does not)
Just my 2 cents, not trying to ruffle your feathers buddy
