Well, after a couple of years on the shelf, I've decided to finish my 34% CA models Extra 300L. This is the older version of what is available today, but it should be an excellent project. I've got a BME 105 for power. I'm thinking of using dual recievers with no powerbox system, just the recievers. I'll use dual reciever batteries and switches, and a Smart Fly Optical Kill Switch. Servos will be Hitec 5955's for the elevators and rudder. I'd also like to use them in the ailerons, but I may use 5925's. There will be two per aileron. I'm going to use a Hitec programmer for the syncronizing.

I still have to do some sheeting on the fuse and install a couple more formers.

Steve, a very nice plane indeed. I have 31 flights on mine with a DA100. I dont do much 3d, but it can fly precise manuevers quite well. Enjoy the plane.

Thanks Ragz,
Did you modify anything when you built yours?

Thanks,
I already have the Graphtec mains. I just need to pick up a Petes Models tailwheel. I plan on counter ballancing the elevators, "I think". I may go a little larger on the ailerons also. I need to look into some wing fasteners.

i use bolts from the inside the fuse to hold the wing roots, rather than bolt from the top of the wings INTO the wing tube. I dont like that method. if u PM me your email, i will send u some pics.

I've followed a couple of Carden threads and I also like the way they have the wings atached.

Got some more work done on it. I added the bottom sheeting. I also added a little extra where the stringers are a little weak due to length.

I also glued in the tri stock on all the formers where they meet the fuse. The rudder tray was also glued in.

After looking over the instructions, there didn't seem to be any suports for the wing and stab tubes sockets in the fuse, so I made some rings out of scrap for the stab tube. Once glued in, I checked alignment and glued the stab tube in place. I also glued the wing tube sockets in place. I'll add some 1/4 X 1/4 to the top of the wing tube sockets. I also capped the ends of the tubes that will be glued into the wings and stabs.

Built the fuel and smoke tank mount next. I used a piece of 1/4 light ply and drilled some holes to lighten it up some. The rails are 1/4 X 3/16 spruce. This mount was set up parallel with the thrust line.
