Even in this side view (at right) you can see the motor wires. For better appearance –after  these photos were taken– I enclosed the fronts of the louvers. Plenty of air enters through the firewall openings and openings in the bottom of the wing just behind the motors. See photo on next page.

The  canopy is stock. I did not even have to move it, and  the  same grey haired pilot  who has flown it–off and  on– for 16 years, says he likes it better as a twin electric.  
Above  are the parts that come with the 2826/12 Pulso motor. The assumption here is that one is going to mount the motor in front of the firewall. This seems to be the case with most motor manufacturers, but we mounted ours behind the firewall. So we used  collets on the prop shafts. We also used a wheel collar

You can tell a lot about the quality of a product by just looking at the external craftsmanship. Little things, like the care  exercised in putting the shrink wrapping   on the extension wires’s gold plugs. For better current flow, the wall thickness of the Pulso  plugs is 0.6mm rather than the standard 0.4mm.
A peak inside reveals that the motor extension wires have been firmly welded. Because welding these wires is a tedious and risky procedure, many other brand motors use unwelded  extension wires. They use  lacquered wire instead. In June, 2009 Pulso introduced a radical design
