Pretty much what you do! Optimize. Adjust in one direction until the result tend reverses. But remember, it is multi variable optimization. Rubber width, rubber length (or mass), prop pitch, prop planform, etc.xiangyu wrote: ↑February 27th, 2020, 7:18 pmHuh, I didn't realize thatcoachchuckaahs wrote: ↑February 27th, 2020, 6:26 pm Remember, the regular Ikara. Is cut down, so the pitch would be higher to match larger diameter. Probably want to re pitch to around 2.0 P/D, then vary from there. Probably between that and 1.5, but we are not using those props, so you need to test.
We are generally between 30 and 40 degrees at 1"radius, but the pitch is definitely specific to the prop planform. I've seen some much higher, some much lower, depends on prop.
Coach Chuck. Well, it's been working so I never really thought about it.
Thanks for the new insight.
In terms of increasing flight times, what should I try next? My propeller I have rn is pretty much matched up to the rubber and I can fly consistent 1:35-1:40 or 1:50 probably if I "risk wind". Also, I am currently using a 39 inch rubber loop and ending up with very little winds when the plane lands. If I keep increasing the length of the loop (which would pack more winds), what might happen, would it keep increasing my flight time until the extra weight of the long rubber outweighs the power from the extra winds? (I'll be testing by experiment this weekend, but just curious atm)
