Hi Electricpete,

I saw your comment about electifying the Jupiter and thought I'd share with you some work I did on mine. I owned a 'normal' gas powered Jupiter for a couple of seasons and enjoyed flying it a lot but wasn't so keen on the mess from glo-fuel. So I had a long hard look at how to convert it to electric power.

The main problem I came up with is that since the Jupiter is moulded its not as easy as on a wooden contructed model to customise motor mounting or battery placement. For example with the batteries you need to put the batteries into the area behind the motor firewall and can't very easily adjust their location fore and aft.

I managed to get round most of the issues but eventually decided to go back to glo-fuel and never got as far as test flying an electric version. I did manage to

To attach the new electric motor mount to the firewall I decided to re-use the original glo motor mount fixing points. What I did was to take the original glo motor mount and cut off the engine mounting arms. This left me with just the circular disc part of the glo motor mount. I then used some new long bolts to bolt through from the glow motor mount, through my electric motor mount and into the original firewall mounting holes. I have attached a photo which shows a 'dry fit' I did of the glo motor mount and the base of the electric motor mount. After testing the fit I then cut the glo motor mount arms off.

For the cog the original glo motor was a pretty heavy item so I used a .60 size electric motor to give me plenty of weight up front

The ESC would then have been situated at the back of the electric motor, in the cowl area to give it plenty of cooling.
