I have been trying very hard to get my bixler to tip stall, but won't do it. My other planes have terrible tip stall tendancies, my dynam catalina and starmax MX2.

I think maybe people having tip stall tendancies may have one/both warped wing with incorrect washout, this is not uncommon with these foamies, which will bend and warp in heat and with pressure eg laying one wing against something for a long period of time. And quality control in the factories aren't high either, so may be like it from new.

Don't forget weight, I was flying FPV, she was nearly twice as heavy as stock, with vTX, camera, antenna etc all on the fuse, this alone will add to the willingness of it to tip stall too.

I would expect weight to only effect the speed of stall, not change tip stall tendencies. Unless the weight isn't balanced, one heavy wing will be bad

Well it's weight above and below CG, I also had 109 grams of landing gear sticking a good 6 inches below the airframe as well. I don't think any of these things by themselves are going to guarantee a tip stall, but I would say the combination makes it more possible.

And it took a flair from a stall recovery even then for mine to do it rofl, I have never noticed a tip stall tendency in normal flight.

Playing around with some props over the weekend I think ive found my preferred prop for the Bix, after watching the video's the difference in props really shows, I was using the APC 6x4 but the MasterAirscrew 5.5x4.5 was so much better, a lot smoother and less noise (before anyone says it.....they are both balanced exactly the same) first half MasterAirscrew second, half APC
prop test (2 min 2 sec)
