Have we figured out how to stand this engine off the firewall yet? I don't think those aluminum columns that many people use can be used on this engine or can they? I spoke with you in Toledo and you said there is some special radial stand off you guys were working on (plates?). I think the Edge I have needs 7 1/4 inch from firewall to the fornt of the prop hub. I'd like to put one of these on the plane (30%). When I measured it in Toledo it was something like 6 plus inches. I'm very interested in one of these.
I just noticed the top right picture shows the distance as exactly 7 1/4 inch. I wonder if this was exactly from the front of the prop hub, it's hard to tell if the tip of the tape measure was right on it or not.
Joe,
Regarding the question about headers,
there are headers available. One of which is a "centerline" header with a 3/4" id that has the usual drop and rise and it aligns exactly with the centerline of the crank. That should work just fine for cannister installations. He's also working on another arrangement where the header angle near the exhaust port can be changed by the user. Direct manufacturer contact would provide better information on all of that.
As for the mounting, the radial mount is 1 inch from the back of the mount to the engine, and I listed all the dimensions as best as I could in a post a couple up from this one. Most of the 50cc planes I fly have a distance of about 7-1/2" from the engine mounting box to the face of the cowl so it should not require anythinng more than a ply or hardwood spacer equal in thicknes to offset the distance between the radial mount and the aircraft mounting surface. I can't see any reason why short aluminum standoffs could not be used as well between the radial mount and the firewall if that's what the owner desired.
When I took the pictures I was using a Macro feature on the camera for better close in detail, so I would imagine that the tape measure would not be as accurate a depiction as it could be. The dimensions in the other post are pretty accurate.
For Everyone:
Since the Taurus 3.2 uses a multi bolt propeller hub it's not a bad idea to obtain an inch pound torque wrench. This actually applies to any engine that uses a multi bolt hub. When you install the prop, simply use the torque wrench to tighten the bolts to
40 inch pounds and periodically check them once in awhile to assure yourself that they are well secured. This applies even more to those that use a wood prop where the hub will compress a little over time. As I said, this is a good thing to do with any engine that uses a multi bolt prop retention method. It's a cheap investment and excellent insurance, and checking the security of the propeller should be a part of the preflight for
every R/C plane.
