Once the canisters are installed, I will work on some baffle plates. I was able to print this true to scale image of the DA 200. I will use this as a template to cut out the baffle plate. I will be using CF thin sheet with poplar.

90 degree head for a Dremel tool would work, or an angle drill. Harbor Freight has several cheap ones that would probably work.

I got it done with this.. do not ask me how I got it in there!!

OK, I need a beer now, or two!! I got it in there and they are solid. I am very pleased with the results, but it was not easy!! let me see if the pics will show you what I have done..
SOon, i will have to undo all this!!! LOL!!!
The good thing is, that the aluminum plate is held in place with 4 screws, 2 on each side, with blind nuts on opposite side. Access to it is quite easy, so I am not worried.
SO that I can sheet the bottom and cut out holes for the stingers, and do the rest of the stuff that needs to be done, like covering the airplane. All that is left is to do is mount the throttle servo, and we will be done.
Then finish beveling the wings/ailerons, and cover wings/stabs, etc....

Sheeted the bottom of the fuselage for the area where the stingers will exit.

Installed the throttle servo: This is a tight install, very little room, seems like the way the headers are designed with this drop, I will not be able to get to the needles for the rear carb ;( ... Nothing is binding or impinging, but very close where the throttle arm is in proximity to the header. If only the headers were out by 1 cm.

Looks great Cam, remember a millimeter is as good as a kilometer!!

started working on the baffle plate. Still have a long way to go to finish this step....

I have glued on the baffle plate mounting tabs.

Then I placed the baffle plate on and positioned it...

Then i drilled into the tab, and inserted a 4-40 screw.

Here is a frontal view. The opening has a 2" height. Next step is to make the shroud.

these are two views of the propeller clearance...

I am going to manufacture my own plenum (or shroud), whatever you want to call it. Basically, it will be something that will contain the prop wash into a smaller area above the cylinders, that way, the air has only one way to go, and that is down and out thru the cylinder fins.
