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!

Cheesy Fresh Corn Grits

Grits are a fantastic side and can be cooked and used in so many ways.  In a short few months, we will be coming up on fresh corn season.  Use the recipe, below, to kick-up your next grits dish.

Ingredients

2 tablespoons Unsalted Butter
1 tablespoon Canola Oil
3 ears Fresh Corn, kernels removed
Kosher salt and freshly ground black pepper
2 cups Whole Milk
1 1/2 cups Stone-ground Grits
1 1/2 cups Grated Aged White Cheddar
1/4 cup Grated Parmesan
Fresh Parsley Leaves, for Garnish

Directions

  1. Heat the butter and canola oil in a large saucepan over medium-high heat.
  2. Add the corn, season with salt and pepper and cook for a few minutes.
  3. Add the milk and 3 cups water and bring to a boil.
  4. Slowly whisk in the grits until well combined and continue whisking until smooth.
  5. Reduce the heat to low and cook, stirring occasionally, until thickened and smooth, about 45 minutes; add more water as needed to keep the mixture creamy.
  6. Remove from the heat, and whisk in the cheddar and Parmesan.

T-6A Texan II – Motor Selection

To continue on with my T-6A Texan II Build Log, I am in the process of determining the appropriate electric brushless motor.  There is a lot of science around selecting the best electric motor for specific applications and, I must admit, I am still learning.

This aircraft is designed for a .75 to .91 cu in 2-stoke engine or.91 to 1.00 cu in 4-stroke engine.  I am estimating the flying weight to be 9.5 pounds.

A good starting point for sizing electric brushless motors is to use the following:

150 watts per pound Scale Flying
200 watts per pound Aerobatic/3D Flying

Since this is a military aircraft, I am basing my initial calculations on 150 watts per pound. With that said, 150w X 9.5 = 1425 total watts.

There are many electric brushless motor, battery and prop combinations that can be used.  So many that it can be confusing.  So any input is greatly appreciated.

UPDATE – I’ve made my decision.  I’m going with the E-flite Power 90, 8S 5000mAh batteries and 16×8 prop.  This will produce 1800 watts max. which is plenty of power for this aircraft.

Options I am looking at right now are:

MOTOR/PRICE RPM/Volt (Kv) WATTS CURRENT CELLS RECOMMENDED PROP
E-flite Power 90
$129.99
325Kv 1800 50amp
65amp max.
6S to 8S LiPo 16×8 to 18×8
E-flite Power 110
$139.99
295Kv 2000 55amp
65amp max.
8S to 9S LiPo 17×8 to 19×10
Hacker A50-16L-V3
$169.00
265Kv 1862 80amps
100amps max.
8S 16×8

I feel any of these motors would work well in this aircraft.  If you have any comments or recommendations, please leave them!
