70cc twin V2







This will be the second plane I have built. The first one was a Lanier Staudacher that I built last year that is the picture of my avatar. I'm going to build this plane just the way it was designed by Kevin Walker.
I know that Terry did a build thread on this plane a while back. I'm no where near the the builder that Terry is, if you don't know who I'm talking about you need to check out the Viper-ST 100-120 build by Terryscustom amoung the other threads he has going. He also did a very informative thread on vacuum bagging.
After reading the Vaccum Bagging thread I decided that I wanted to vacuum bag the foam in this kit. I ordered the EZ-Vac pump kit from ACP Composites on Friday and I hope to get it next week. I also have decided to use the West System resin instead of the poly glue I used on my Staudacher, so this is totally new to me but I'm looking forward to learning something new. I have a buddy that is wanting to finish his 38% Laser 200 so we will vacuum bag his wings too.
My shop is not real big, it is only 10' x 22' so this is going to be a cramped build, but I will make it work. When it comes time to set the incidence I will move it over to the garage where I have a lot more room.
Here are the spec's on the plane.
Wing Span: 119"
Fuse Length with spinner 109"
Weight depending on set up: 26-28lbs
Motor 85cc-100cc (DA100 recommende
Well enough of the chatter lets get to building. I looked the plans and the manual over and got started on building the fuse sides today. I have a piece of 3/4" MDF that I will use for my building board. I picked up a couple of pieces of 6' X 3/4" aluminum angle and screwed them down over to plans and wax paper. I scarf cut the stiffest and straightest 3/8" balsa on the sander to make the longerons and attached them with clamps to the 3/4" angle. If you notice I ended up using binder clamps that you can buy from Staples, these are really cheap and they work extremely well for holding the longerons against the angle. I got all the sticks cut and glued in place. I pulled the sides up off the plans up and splined sanded them. I used several sheets of 80 grit sand paper attached to another piece of MDF. After I had both sides sanded I glued in the anti-rotation doublers and the stab/rudder servo plates. I have gotten about as far as I can now until I get the motor box built. I'm going to try and get it built this week.
