Good save! That’ll get you’re attention!
Im not a fan of single connectors to gang up multiple servos either. In all my experience I’ve never had a plug failure because mine are separated and secured with plug locks.

The DLE 61 is very different from the 55RA. I used the Xoar 22x10 on the 55RA in the Corsair and it ripped, great performance. The 61 in the Corsair is just not the same, it’s much slower and harder to tune than the 55RA. I’m using a carbon Mejzlik 24x10 on it right now and it’s able to climb pretty well but level speed is much lower. I’m thinking of going to a smaller prop like you and see how it goes, maybe more pitch like a 12 or 14 to make up for the lack of revs.
