It is a plans build project with many building hours but at least i can build, at my own budget and time.
Planning to start building the wingspar still this summer season , nice hot and dry weather in ZA
Helped a friend on a BD4C project for 3 years and finished the project in 2012.
It was the first project flying and completed in ZA of the BD 4 C version.
Very fast aircraft ( taildragger) and is a high time plane that controls excellent in flight.But be warned difficult to land (taildragger version) It will bite any pilot if there is a lack of concentration on landing!
We won the President's Trophy Airrace with it in 2014 and finnished 7 th this year.
It has a lycoming IO 390 in it (210 hp) think that a renesis will do good as the BD have lots of space firewall forward.
Will post some photos to you in person, don't know if the group is the right place for it las i don't know the rules
Cheers

Le Roux,
I hear you. To me, the p/u version also makes more sense. PL was so against it, though, that I thought it`s not worth doing.
What plane are you building? I am rebuilding a Bede BD4, and the rotary is not off my menu.. I have a Conti io 470 for it, though.
Regards,
Erik in Oz.

Erik :The plugs up version suites me better as there is for me more advantages than disadvantages.
If the intake manifold stands upright, then the throttle body is just in the right place, for the intake duct of the cowling and to make use of the ram air effect and simplicity of placing the air filter.
The hot exhaust exit, is in the middle under the engine, and with no complex bends that must passes the engine mount spaceframe. The exhaust exits the cowling on the same way than any other aircraft engine like lycoming or continental.
The oil cooler sits under the psru as in the normal version , and the air passes through the oil cooler, helps with the removing of the radiant heat of the exhaust as it is in the middle right behind the oil cooler.
The radiator can be side mount co-pilot side as there is enough space due to the side sump.
The gravity feed of oil that flows back to the side sump is in any way the same as in a normal version.
I think that I don`t have to “invent the wheel” as it was been done before by a genius builder.
As Lynn E Hanover always says and I quote: I could be wrong!

Hello Le Roux
Beautiful work. I find it interesting that you chose to do the plugs-up version. Any particular reason?

Completed the intake manifold for my 13B "plugs up" mount.Adjustable for the best performance (18 - 24 inch) then can be locked by silicone 50 mm hoseNext step to place the 4 injectors on the 44 mm intake runners.
