Hey, I am having some issue thinking that is NOT directed to me.....;-)  Seems I have had them all plus some....but so far, only on the ground....so far.  Geesh.

 

Now, Gordon, not to dissuade you, but I gotta ask, why are you wanting to go "plugs up"?  Ed mentioned a couple of the advantages (which I consider pretty minor) and in the old days, IIRC, plugs up was used to allow top clearance, especially with the old school distributors.  However, that is not a big an issue now.  Also, your turbo may take a lot of room unless remotely mounted.  I think that the Defiant (kewl plane BTW) has quite a bit a room compared to some planes....EZ's come to mind. Heck, the EZ I saw with a rotary must of been installed with a shoe horn.  While not overly roomy, my turbo rotary 13b, in my Velocity would have been much more difficult, I think, plugs up, especially since it would have required even more fabrication...which may not be an issue for you.....

The tech took my transponder since it was not properly reporting altitude to have a look....but when that problems is solved....on to a squawk party and then to call a DAR.....YIKES!

Welcome, Gordon!

 

Wikipedia claims only 100 sets of plans for the Defiant were sold.  How far along is your plane now?  You will shortly hear from Ed Anderson I am certain.  He is the plugs up guru for this list.  You will find a lot of really sharp guys here that can help you with almost any problem.  We have had all of them!

Hi all,

 

I’m new to the flyrotary (FR) list and am building a Defiant with two turbo 13Bs.  I am looking at mounting the engines “plugs up” as described by Neil Kruiswyk and tried to contact him at the home.com address listed on the FR website.  My e-mail keeps bouncing back.  Does anyone have a current address for Neil?

 

Beyond that, I would like to identify others that have mounted these engines sideways (plugs-up).  How many hours do your projects have on these installations?  What issues have you uncovered that may be related to the plugs-up orientation?  Has anyone found (more than expected) difficulty cooling that may be related to air pockets in the cooling jacket?

 

What about engine mounting?  How do you grab the engine block?  Have you looked at the stresses at the attach points?

 

I’m also considering a constant speed prop.  Tracy Crook advises me that his PSRU will accept only electrically adjustable props and I have identified IVO and MT as possible suppliers.  Are there other electrically adjustable props in this power category?  Are there other PSRUs that accept a hydraulically actuated prop adjustment?

 

Thanks in advance for any advice you all can offer.
