Electric Renny 2ME Version 2

I’m a Beginning Builder and Flyer.

I’m putting together a Northeast Sailplane electric Renny 2ME Version 2.

I have lots of questions since this is the first plane I’ve ever built.

Question One is about the V-Tail.

When I attach the Rudders to the V-Tail panels are they only supposed to rotate in one direction?

The rudder hinge line has an angle to it. And as I put Hinge Tape on the Rudder and V-Tail Panels, it appears that it will only rotate in one direction.

Is this normal?

Since I can't figure out how to load photos into this thread....
I've put the photos of the V-Tail here:

Hi I'm Bob in Seattle. V tails are not easy for a first time project. I am also struggling with a V tail on an Omega. Call around your local area and find a hobby store or club that has a V tail ship built or on display. Go look at it very carefully and see how this thing works. It's not obvious or easy, but once you see it in action you'll understand what you have to do to make it work. Bob

Just from looking at the first pic,you need to put the hinge tape on the other side of the rudder/elevator.That will give you travel in both directions.

Next step Servos in the Wings

Today I will Attempt to put the Servo's into the wings.

This will be when I cut open the beautiful monokote covering with an unskilled hand!

Here are the wings before I destroy them.



I hope that IMage tag I used works.

Well my Renny instructions don't give me a clue as to where these parts go!

I guess Parts are Parts!

Do anyone know where these parts go?

I hope I inbedded a picture, if not here is my desperate link.

NewBee Question Number 45

Well, I just thought I'd move onto the motor since I'm stymied with all the other parts in this model.

I have a great little Hacker motor that goes in the Renny. It comes with a plastic disc the same size as the plywood disc of the Renny. The Renny plywood disc has a hole so large that the Hacker motor can’t bolt to the Renny Disc.

So do I glue the Hacker plastic disc to the plywood Renny disc?
Then do I cut holes in the plastic disc to match the holes in the plywood Disc?
And then mount both disc into the fuselage?

Hi Don,
I have a Renny NIB, so I am very interested in this thread. Based on some previous experience with sailplanes, I would say the triangular horns on the right are the flap horns to allow more down flap travel. They also induce some differential towards the down side because of the shifted pivit point. Again, good for flap use.

later,
Mel D.

Well…. Onward to placing Servo’s in the Fuse.

How do you determine placement front and rear for best CG?

I have found two other photos here in RC Groups.
The Red plane is “Stuntman” and the Yellow plane is “Charger”

The Red plane mounted the Servos “Between” the Wing Bolts.
The Yellow plane Mounted the Servos “Forward” next to the front wing bolts.

How do you determine where to mount?

Don

Hi Don, I have only built up 4 electric ARF gliders. So I am not an expert. Having said that, here is my opinion. The wood motor mount is just a universal mount that they give in the hopes that it will fit your motor or gear box. It didnt fit your motor gear box. The plastic mount is made for your motor. I would make a 1/8 th inch thick plywood mount like the plactic one and use it. I wouldnt use the wood one they gave you or the plactic one that came with the motor. The plastic one looks to weak to be safe. Just make up a plywood mount useing the hole patterns in the plactic mount. I am assuming that you have some basic shop tools. When you mount it in the plane don't forget about the proper thrust angle. It's usually 3 or 4 degrees down angle and 3 or 4 degrees to the left. Good luck

I built my Renny a couple of years ago, I have lots of hours on it now, I'll dig out some photos and or take some more, I did a few things a little different that worked out well. I hope the instructions are better now than 2 years ago. By the way I didn't use any of the supplied control horns, a used aftermarket nylon stuff I'll try to include a photo of those. I also ran the controls for the v tail over the top and connected them to the top of the ruddervators. pictures coming tonight. John

Renny Instructions no Change over years

Thanks for everyone’s help and input.

The Renny instructions are cryptic.
I think they were transcribed from a Slavic language I think.

I did figure out that it is best to mount your servo’s forward toward the nose of the plane. The fuse tapers as it goes back, and this tends to limit the length of your Servo arms.

Renny build

It's a little tight fitting the servos in the back but I have plenty of throws on the servos, mine does really tight loops. In the attached photos please note the servo arms arm epoxied on, just make sure you cut off a little square of covering and glue straight to the balsa control surface. I ring mine out pretty good sometimes and never had an arm come loose. my over the top method takes away all the headaches of fitting the controls inside and inline with the rear boom opening. You'll need your battery as far aft as practical to keep the CG right and if you put the servos in front of the battery you'll never get the battery out for charging, my battery is a new polyquest 1800 3s "20"C My aileron rod is a carbon fiber rod glued into the rod ends. Also sorry about the sloppy tail attachment I had a crash last fall and had to cut the tail back out to rebuild it. it still looks great from 500 feet away. Good luck John
