Charger RC CR-1 Build

Thought I would Post a Build Thread on my Charger CR1 Foamy. This is my second CR1. I wore out the first one. This plane is a lot of Fun. It is larger than the standard foamy, and is made of 6mm depron. To me a foamy should fly Like a foamy. I have tried the more expensive airfoiled and built up type of elecric 3D planes, but prefer larger flat wing foamy type of planes. Here is what will be used in this plane.

HS-55 2 for ailerons, and 1 on elevator
HS-56 on elevator
Cyrus 4ch single conversion receiver
Hackler A20-20L
APC 10x3.8 slow fly electric prop
Castle creations 25A speed control
ThunderPower 1320mha 3 Cell 11.1 Volt battery
Deans connectors
CR1 http://www.chargerrc.com
Optional Landing Gear

I will be using liquid Nails #1 Formula for gluing in the servos, rcvr, motor, speed control, and landing gear. I use this glue on all my Famys. It is extremly strong, light, and remaing flexable, when dried, instaed of brittle like CA.

Here is everything that comes in the kit. There are CF for the pushrods, a nice decal set as well as depron templated if you choose to paint. I will be using the decals.

Next thing is to cut the bevels in the control surface. I typically make the initial cut with a straight edge and a razor blade, then clean it up on a belt sander.

The Fuseladge and Wing Has interlocking tabs and just snaps together, medium Foam safe CA is used to glue it all together, then the Rudder Is taped on. This step took 5 minutes.

A small peace of tubing holds the wheels on to the prebent landing gear. The gear attaches with two zip tyes.

The motor is attached to the included aluminmum motor mount, with the included screws. This mount gives a lot of surface area to glue and really strengthens the front of the plane

The foam had to be removed in the rear of the motor mount area to allow clearance for the rear bearing of the motor. A soldering iton was used to do this. The motor/mount is glued on with #1 formula

I added a small scrap peace of flat CF to the elevator to add some strength.
