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.

T-6A Texan Motors

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!

T-6A Texan II – Build Log

About two weeks ago, I started building a T-6A Texan II.  This is the Beechcraft version built by Raytheon Aircraft Company.

In the image above, the fuselage is about complete.  I am fitting the cockpit items; dahs and pilots.  None of this is glued in place yet; I still have some trimming of the front dash to do.

This should be a very cool airplane!

Specifications

Wing Span 63.0″
Wing Area 647.9 square inches
Flying Weight 8 to 9 pounds
Length 58.3″
Motor Working on power configuration.
E-flite Power 90 or Power 110?
Hacker A50-16L?
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.

First Cilantro Harvest and Process

I harvested and processed fresh cilantro from the garden today.  Once your cilantro is ready for harvesting, cut from the plant, discard and brown leaves and wash.  I then let it dry on a paper towel overnight.  Lastly, I dry my cilantro for later use.  Using this type of drying approach, the cilantro will stay for up to 24 months.

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.

2014-02-24-BeefsteakTomatoes268x200

Planted More Beefsteak Tomatoes Today

It is a beautiful day out today so I thought I would do more thinning and transplanting.

Today I planted 2 more Beefsteak Tomato plants. These should be ready to harvest in late May to mid April.

2014-02-24-BeefsteakTomatoes2_268x200

More on Tomatoes…

I also planted more Rosemary and Greek Basil.  These should both be ready for use in about a month as they are already very mature pants.

This is the advantage of sowing seeds, indoors, early in the season!

FettucciniAlfredo268x200

Alfredo Sauce

Alfredo Sauce

Author: Bob Mixon

Alfredo sauce is very versatile and wonderful over fettuccini and other pasta. Use this basic Alfredo sauce over pasta and add broccoli or shrimp. ~yum~

Servings: 4

Ingredients

2 cups (1 pint carton) Heavy Cream
12 tablespoons Unsalted Butter
1/2 tablespoon Fresh Garlic, Minced
2 cups Parmesan Cheese, Grated
2 cups Asiago Cheese, Grated
Salt and Fresh Ground (white) Pepper

Directions

1. Add heavy cream and butter to a large sauce pan and cook, over medium heat, until butter melts; about 3 minutes. The key is to heat this slowly as to not scorch the mixture.

2. Add the fresh minced garlic.

3. Slowly stir in small amounts of the Parmesan and Asiago cheese. Stir sauce continuously as the cheese melts.

4. Once all cheese has melted, remove from heat.

5. Let the sauce stand for 5 minutes before serving.

6. Salt and pepper to taste.

Notes

Fettuccini Alfredo – Add this Alfredo Sauce to cooked Fettuccini and mix. After the butter has melted, step 1 above, add 1/2 cup fresh lemon juice. Once you have combined the Alfredo Sauce and Fettuccini, incorporate 2 teaspoons grated lemon zest and a small pinch of nutmeg. Top with steamed broccoli, asparagus or shrimp.
