If the engine is new - you probably want to start with a 20x8. If it is setup well and broken in - you could go up to a 20x10 or perhaps a 22x8.

You could also try something like a Xoar 20A - the Quadra 50 and 52 seem to really like a variable pitch prop.

How about 23x10 MSC prop coz i have it on hand atm...

I'm sure it's well set up and broken in...

A 23x10 is too much prop for a Quadra 52 - the Quadra 52 would be considered underpowered compared to current "modern day" 50cc class gas engines. Most current 50cc gas engines would struggle with a 23x10.

Most current 50cc class gas engines would use a 22x8, 22x10, or 23x8. I think the largest prop you would want to try on the Quadra 52 would be a 22x8. You are better off staying in the 20" prop range.
