Default Kaos Electric Konversion

My electric conversion of the Tower Hobbies Kaos is described in the PDF attached.

Technical details are found in the spreadsheet towards the end before the photos.

This plane's photo appeared in February 2014's Model Aviation.

More pictures!

I'm planning to do a King Kobra. Axi 4120/18 and Jeti 60 from about 7 years ago (because I have them) I bought the kit immediately upon hearing Sig planned to discontinue it.

Default Bridi Killer Chaos Electric Conversion

I spent the last 2 weeks converting my trusty old Killer Chaos to electric. For those not familiar with this version of the Chaos line, it has a 62" wingspan, 57" length and 700 sq. in. wing area.

I built this kit (the BlueJay version) about 10 years ago. It had a Super Tigre G.90 with a long tuned muffler, Perry carburetor and Perry fuel pump. 7.5 lbs. empty; 8.25 lbs. fueled. It boogied along pretty good. :-)

For the conversion (my first), I installed a Rimfire .80 brushless motor, Castle Talon 90 ESC, Align 5200 mAh 22.2v 6S 65C LiPo battery, an Arm-Safe port and a 3-blade 12 x 8 propeller. The net weight savings with this combo is 9 oz.

I put the first flights on it this morning and I am ecstatic with the results. The flight performance is every bit as good as the nitro engine, but without the mess and vibrations. And the battery measured 71% capacity remaining after 5 minute flights. In other words, the battery is way too big.

I ordered two 3300 mAh 22.2v 65C batteries which will save another 7 ounces a still give about 6 or 7 minutes of flight.

As to temperatures, the motor, ESC and battery run lukewarm, even during aggressive, high power settings aerobatics.
