AeroWorks 30cc Extra 260 Conversion to Electric – Motor Mounted

This is the second article in my AeroWorks 30cc Extra 260 electric conversion project.  In the first article, I listed all of the electric parts I am using in the build.  In this article I show how the electric motor is installed.

I mounted the electric motor in my AeroWorks 30cc Extra 260 yesterday.

And here is what the airplane looks like now, with the electric motor.

I used the same DLE standoffs and fabricated a simple motor mount.

It is simple, light and rock solid.

I was a little concerned about how this would come together, but all in all, I am very pleased with the end result.

The ESC is mounted below to get as much air cooling as possible.

 

 

 

 

 

 

Tomorrow I plan to complete the installation and go flying!

AeroWorks 30cc Extra 260 Conversion to Electric

I have been flying my AeroWorks 30cc Extra 260, 76″ wingspan, for over a year now.  I have more then 200 flights on it and absolutely love it.  Its a wonderful aircraft and can do any aerobatic maneuver you ask of it.  The only issue I have had with the airplane is the DLE 35cc RA gas engine.  I have done just about everything I know of to resolve the “load up” issues, I have finally given up on it.

Electric power is so advanced now that I thought this would be a good airplane to convert.  I have been flying smaller electric airplanes for ever but this is the first of this size.

After many conversations and questions on RC Groups, asking friends and other experts, I finally settled on the following configuration:

Electric Motor MOTROLFLY DM-4330-298
298Kv, 2700 watts
ESC ZTW Gecko OPTO 120amp HV ESC
Arming Switch MPI Spark-eliminating, High Voltage Arming Switch
Connectors EC5
Motor/ESC Connectors 5.5mm Bullet
Batteries 8S 6600mAh, (2) 4S batteries in series

Here is the new motor, ESC, arming switch and series battery connector all wired together.

Next, I need to get it mounted in to the airplane. I am currently waiting for some additional parts. As soon as its all mounted, I will take some pictures!

100cc Extra 260 IMAC Competition Aerobatics Build

One of my favorite airplanes is the Extra 260.  I have many in various sizes.  This is my AeroWorks 100cc Extra 260; which I use in IMAC International Competition Aerobatics events.

Wing Span 104 inches (8.6 feet)
Wing Area 1867
Weight 27 pounds
Engine 3W 110cc CS Gas, 12.8 HP
Servos (9) Hitec Digital (Programmable)
Power Distribution Smart-Fly Power Expander Pro

3W 110cc Competition Series (Twin Cylinder) Gas Engine

I decided to power this aircraft with the 3W 110cc Competition Series Engine instead of the DA-100 because of the horsepower it produces.  The 3W 110cc engine produces 12.8 horsepower; which provides unlimited vertical for hovering and punching out of any maneuver.

Electronics and Flight Controls

The electronics and flight controls have become very sophisticated.  Programmable servos, multiple servos on all flight surfaces, remote receivers, optical engine cut-off, backup and fail-over systems and more…

Each of the (9) servos are connected to a dedicated receiver channel.  This provides the ability to fine tune each servo.

Smart-Fly Power Distribution

The Smart-Fly Power Expander Pro provides power distribution, regulated voltage to all servos and fail-over power (battery) management.

Cockpit

Cockpit detail is required to for IMAC competition; both pilot and dash details.  Besides, it looks cool…
