Made a little progress last night, here are some pics as promised. I didn't have to modify the tunel because I shortened the header. You could leave it the full 12" and cut a hole at the back of the tunel.

Eric,
It's looking like yours is coming along nicely. I will be using the front exit canister and I don't think I'll have to cut my header. I wont be able to get to it until next week anyway.

Now I'll assemble the 32oz Dubro fuel tank and mount just ahead of the wing tube. Since this plane is on cans, I've placed an aluminum or brass tube for the vent line that will run between the cans. The exit is just ahead of the landing gear.
At this point you should assemble the entire aircraft assuming the exhaust is on as well. Be sure to include the prop and spinner because we're going to need to check the CG and mount the batteries and such. CG is approximately 7" back for this purpose.
Now that I've located good positions for the batteries and regulators and checked the balance we'll go ahead and fasten them in. These locations are what I am using for the DA-100 so you may end up further back or foward depending on setup.
Again getting back to the canisters, I don't want the heat from cans going back into the fuse. So...I am going to remove everything in front of the wing tube and cover it with matching Ultra-cote and reinstall. Since all my holes are already drilled, this will give me a very clean looking install.
Side note: I have drilled holes for the zip ties holding the tank in because I am covering the lower deck. Otherwise, it's not necessary.

I just recieved all the extentions today and I now have the canisters for the DA-100. Time to get these finished up and get them out to the feild. Now it's time to get that 85 installed as well. We should have some video of the 100cc up on the web site soon as well.

so is the 98" length with or without spinner wondering if this will fit in my 06' f-150 regular cab
That's without the spinner.
On another note, I've been getting asked a lot of questions about the DA-85. I will try to get started on the 85 install tomorrow evening or the next. Here is what I have thus far. DA recommends not using standoffs for this motor. If you look at this picture I posted earlier of the motor, I've had some wood base mounts rings made to mount this motor. Since DA provided the template with the motor, it was pretty easy to do. With the eye balling I've done to this point, the carb will be off the firewall just a tad. I still plan on cutting a hole in the firewall for the carb intake. There are other ways to achieve the correct mounting of this motor but this works for me, and looks nice as well.

Ken--
You shouldn't have to cut the hole in the motorbox. We have several guys flying the DA-50 on warbirds at my field with the carb really close to the motorbox. It runs just fine that way. I don't see why the 85 would be any different

I agree, but there are other reasons for doing so. One, I'll shed a little weight and it will make my throttle easier to install and second, the carb will be taking air from inside the fuse at a more constant pressure. Eric, how far is your carb off the firewall?

Not much about 3/8" I think. I know that some of the other kit manufacturers are recomending cutting out the fire wall for the 85. There is quite a few engine mount sugestions for the 85 on FG. I like WH Toms idea using four 3/4" sq hardwood standoffs and boxing the top and bottom with light ply. He left the sides open for neadle adj. I had made alum. stand offs and have them installed on mine. I'm planning on a redo with this method. I should have mine flying next weekend weather permitting.

Thanks Eric,
I am getting ready to start mounting the DA-85 for mine. Hopefully I'll get some photo's up tonight. Good luck with your maiden, I am sure it will have you smiling.

Part one of getting the DA-85 mounted. I made a copy of the template DA provided and rechecked the measurements. As with the 100, draw a vertical and horizontal line on the “+”. Cut out the copied template and tape it to the firewall making sure your lines intersect the template. Mark and drill for ¼-20 bolts.
