It is time to start the next project...in the midst of other projects of course. This will be my fourth Vario build and while I do have a several other helis, Varios builds are my favorite...the only limitations as we all know are time and money!

After flying Doorman's eBenzine I wanted to do the conversion and it was time to get my new Benzine a new "set of shoes" so to speak and something new to wear.

So this build thread will be the slow methodological journey from Benzine to eBenzine to eVario EC145 running a four blade head, etc, etc...

This is the end in mind. Stan, this really is the one!

So in the beginning this is where we started...a stock Vario Benzine with a G230 gas burner...good but about to get way better.

Out comes the motor, exhaust system and fuel tank making my Benzine look a little naked

With a Darrell Sprayberry mount kit from EastCoast Helicopters and some new electroics we are off and running.

Quite a difference i know. I am running a Hyperion HS4035-0400 Motor with a ICE HV120 ESC and a Castle BEC Pro on 12S...a beautiful thing. This is running through the standard gearing and Vario clutch delivering a headspeed of 1200.

It flies like a dream...So from there it was time to gather up all the other do-dads to build the EC145. The Vario EC145 is huge!!! or as my grandson says "ginormous"!

While the eBenzine looks a little empty be assured she is ready for the task ahead.

Next phase is the set up the 4 blade Vario head and stabiliztion system. For stabilization I will be using the Helicommand HC3-SX. But before that goes in it is just setting up the head, the links, the follower and getting the pitch set.

Next will be setting up the stabilization and sorting that out...stay tuned.

Wow that is a cool topic, I am thinking of doing the same thing to mine in my Scratch build Cormorant.

Did you take the weight before and after the conversion?

Very nice e-power conversion!! It's cool to see more folks coming over to the dark side...e-power Do you plan to eliminate the electronics tray, so you can do a full cocpit?

All helis and planes have an expiration date stamped on them...you only find it after you crash!!

And moving the follower so the links are vertical I hope. The SX will do the phasing for you.

I did a Florida Hospital EMS BK117 once. I just got it finished and took it down there to show them and they showed me their new EC135! The BK was gone.

They could have asked me if I minded them getting a new helicopter, just no consideration some people

Going To Be A NICE UNIT!!!!!!!!!
Paul,
The subject heli really looks great... it is going to be a show stopper for certain the way you build....
Looks as if you have the head ready for some "final" tweaking... and like Peter mentioned the links will be vertical when we start the set up.... we might even be able to get it ready for the next test hops tommorow afternoon...... LOOKING GOOD!!!!!!!!!

Peter, you are right.... that was not very nice on thier part!!! Some people!!!!

Benzine to eBenzine weight
Yvon,
I did not weigh it before the conversion and wish I had...my guess is with the 2 6S 5000mah batteries I have dropped 2kg.

It is definitely lighter...I am just not sure how much. You can tell it in the heft of carrying the heli and the flying. The other big thing is lack of vibration. In the gasser configuration it was well tuned but had the tell tale small vibrations that the gas version has. I would be lying though if I told you the gasser Benzine didn't fly well. So did my turbine Lama.

Below is a pic of it and my grand daughter, she is sad because she wanted a ride in it!!! Now that was an awesome project...should have never sold it.

Thanks

That Lama was quite the ship but I'm sure the 145 will be a stunner as well.

HC3-SX
After a couple of afternoons of trying to think in German...just joking... I figured out the manual and software interface on the Helicommand HC3-SX.

I really like the way the unit programs once I figured it out. It is small as you can see and replaces the tail gyro, provides a head gyro system and on the SX even has the horizontal control which allows for leveling the heli to the horizon. I programmed the unit by loading my swash type, configured for scale flying.

The head is set up shown with the pushrods vertical and the follower locked down to provide that layout. The HC3-SX then allows you to set the phasing till you get it where you want it.

Doorman met me at the field and we tweaked it just a bit and then put the eBenzine with the HC3-SX in the air. One word, sweet...she flies awesome with the unit and the 4 blade head. So with that being a non event even in a stiff breeze we go on to the fuselage build...

With the rest of the weekend weather appearing to be a blowout I should get more progress done and some pics to show...
Stay tuned.

Your project is coming along great.

I am following your thread with interest as I am on a similar path with a Vario BO.

Can you tell me what value (degrees) in Helicommand setup software you used to achieve your successful test flight?

Mike

P.S. The Hyperion motor you are using looks a lot like the Scorpion range of motors. Does anybody know if there is cooperation between these companies and if there is an interchangeability of parts possible?

Hi Mike,
Thanks for your interest. First, Hyperion Motors are made by Scorpion I have been told.

Secondly, if you can tell me which paramaters you are looking for I will be happy to share.

The pitch curve is running -3, 4, 9 at the top. I am running a flat throttle curve. All ATVs are at 100% and the transmitter is set up as a single servo swash. The Helicommand basics programs everything. I can even take screen shots if you like.

As I did the setup in the Helicommand I used all of their recommendations for scale. The only thing I tweaked was the phasing by 5 degrees.

Let me know what you are looking for.
thanks

Oop’s sorry Rckfish. My question was very vague.

I do not wish to intrude on your thread more than necessary. Please visit mine at https://rc.runryder.com/t635651p1/

Stan (doorman) was kind enough to communicate a lot of useful info to me and Joe (East Coast Scale) has been of great help as well. (Gentlemen such as the aforementioned are a credit to our wonderful hobby).

Mike,
Yes Joe and Stan are awesome...I am lucky enough now to have Stan living close by!

Don't hesitate to ask any question...that's what threads are for.

great project, looking forward to see how it goes. One question, was there any particular reason why you went for the helicommand HC3-SX and not the helicommand rigid? I know they are both rigid but i am interested in your view as i will be going down this route myself soon with a vario 412.
thanks

Allan,
Basically I liked having a small unit that can even replace the receiver by using satellites.

And I felt like it was newer updated technology...that is pretty much it. I did not have either and needed to purchase a unit.

Thanks

I watched Danny from Esprit run his heli through the paces with his HC3-SX and it was a rock solid performer. I'm so comfortable with the set up of my VBAR that I was hesitant to try a new learning curve. Maybe some day...

I can walk you right through the setup if you ever go down that path.

Thanks bud! How would you compare the programming and tuning to VBAR? Is it straight forward and user friendly like vbar 5.1?
