Can't put fairing around stock electric prop engine anymore..

As the title says when i put the fairing on the front of the engine the engine won't rotate. When i put it on the back it explodes as soon as i stage to start the engine. Tried it without blades and that made no difference as soon as i deploy the fairing the engine rotates freely again.

In the past, new versions have broken some bearing designs -- not the concept of the design but the details of spacing needed to change. Version 1.7.0 has not been too bad, so probably you will be able to recover.

One reasonably sophisticated example that works unchanged in 1.7.0 is OffesIsMyName's

Thanks! The bearing itself is fine though, it's like the fairing just stops it rotating..
