I use some different tiger motors that have regular round 5mm prop adapters, I think that those should be able to be drilled out or modified in some way. I am also interested in the tiger 9x3 carbon props though quite pricey have a similar profile to the Vision props and are a very high grade factory balanced carbon prop. So far I havent seen local stock of either props and I am still quite happy with the GWS 9050 triblades performance getting around 8 min flying around 1350-1400g with my gimbal and 2700 or 2800mah battery.
I really dont know how much smoother they can be with gain adjustments but my pretty much default gains have given pretty good results in calm conditions. They get a bit nasty in strong winds but that winds at 40-50kmh with a heavy phantom so I don't think too much can be done there regarding that but if the wind ever stops I will see if I can get mine tweaked as well as possible. Recent 20kmh winds are pretty calm here and so its either fly in wind or stay grounded, maybe should have stayed gounded the other day as I had a pretty nasty crash after breaking a prop. All my error still as I went through a tree pretty hard but flew out of it landing and inspecting everything. I hadn't noticed any issues and thought I checked the props very closely but about 10 minutes more air time when getting some higher shots from about 70m a blade broke and it came down fairly hard after hearing a pretty nasty sound in the air as the prop failed.
I find these GWS props quite frail and if you ever contact a branch best to replace the props as they are pretty cheap about $20 for 2 full sets here. I have hit this same tree on a few occasions too as its on my local FPV test track and did notice a hairline fracture on a prop after each impact i flew away from. This time I must have missed it but light was a little low but really not worth risking a full setup over $2.50 or $10 in props. I was lucky it came down in very long grass and hasnt had much damage but the shell may be slightly bent so I think I will replace the top with a spare I had. Broke all 4 props too and possibly damaged my vtx antenna again.
