Default prop Question

I'm running The Red DJI 920KV motors on 4s mounted on my Disco and they don't seem to perform like the 95s I used on my fly away. Although I had different motors ( TBS 900kv's) these motors have a bit more pop when mounted on my F450. This disco has a bit more weight indeed ,what do you recommend I buy to get my disco to fly better using these motors. Finding the right prop with the flat spots in the mounting hole is a bitch. Everything I find won't fit these motors.

I just drill mine out and don't worry about the flat spot, I'm sure someone will chime in and tell me they are now unbalanced and my quad will fly like but I don't know any better and have a blast doing it.

450 size quads up to around 2kg go well on that spec motor on Graupner 9x5's, I am using them on my TBS Disco Pro with similar 2212 900kv motors on 4S, very happy with the performance.

Those are the 9.4x4.3 props for DJI platforms that can't use the self tightening props. They are notched for the DJI motor shafts.

I have the self tightening version on all my gals and 3s or 4s give excellent performance. Although using 4s gives a lot more pep to your step.

Do they have those that fit the notched DJI motors? But then again I was checking out my motors tonight and one of them is not sounding well at all. Second time I put bearings in it too. I think I'll just order 2 T motors to match my My 2 good TBS motors and get a set of 95s so I can get back to flying with confidence. Dam I hate using my CC but oh well.

Thats what I'm using now. There o.k but not as nice as the ones that came with my Disco . (Graupners 95 ) . They are a prefect match for this rig, like I said one up I think I'll just bite the bullet and order a couple of new motors and Graupners and get stop messing around with these DJI motors. Then I will replace the bad DJI motor and get a K2 board so I can re build my F450 for my back yard basher.
