Electric motor backup

Electric motor back up giving 20 mins of low power when your piston engine fails.

It's a great idea, especially if you can replace the starter motor and alternator with it. It'd be really nice to get an extra 20hp on climbout through using a cruise prop and having a little electric boost, followed by regenerating that power off the motor later. If you could tune it for the amount of drag that you got at Vbg, it could be a great safety feature.

 

(Also, you can put the batteries in the tail or wherever you need to to correct CoG problems. What would be fantastic, if you could get the wiring right, would be a battery you could slide along the rear fuse and get CoG near optimal every flight.)

This must be the sort of thing "ONE Aircraft" is talking about with their new recreational plane? They are calling it a hybrid system to give an extra 25Hp on take off, but not sure if it de-couples to provide emergency power. The set up looks a little heavy to me.

Weight is your enemy. Nev

Really great, it would be better to integrate it into a stand alone gearbox to replace the Rotax one but.

 

Might cut a foot off the length and save some weight. Also removing the extra (electric) motor mount.

 

Considering the Rotax gbox already has clutches inside, these may not be necessary or could be combined with whatever setup they have....

 

That much weight, that far out, currently must load (overload?) the existing engine mounts somewhat.
