Hello
I totaly agree with SAB
Steph Carrier tried the contra adverrun on one plane and the three-bladed Falcon with a Plettenberg motor on the other.
After tests he equipped the second plane with a Plett and three-blade engine.
I asked him why.
The reason for the contra is to brake on the descents but as the braking is done from the front, the yaw stability is less good..
