Can anyone have the drill holes template for mounting the MVVS58 on the composite-ARF 2.3m EXTRA 330L. I used MVVS58 with KS Canister as shown so the mounting of engine shall be side mount.
The template that I used is not correct when I mount the engine dome on the fuselage and cover with cowling, look through from the front, I saw that the center line of engine is not at the center for spinner back plate.

The only way to do this accuratly is to put the airframe on its tail, and place the engine in the position you require, set up with thrust lines and attached to the exhaust, put on the cowl and move the engine around until you get it into the required position, spinner back plate in the centre of the cowl opening, gently remove the cowl without disturbing the engine and mark the mounting holes, it will be easier if you remove the carb and put extention studs on the mounting flange, carefull of debris entering the carb.

Thank you Mike. I got an idea and will do as the same you described. I think this is the most accurate way.

MVVs adds tack screws to their extension back mounts for this very purpose.

Hello Khun Prapan

Pic of what Pe is talking about, the small siver things adjacent too the stand off, note the fixings are not attached on the first photo, the second photo shows one of the stand off spacers in position to centre the drill to make the hole in the bulkhead, third photo shows the mount with its fixings in place, note the bottom Isolation mount (top in the photo) is upsided down to enable fitting into the not quite large enough bulkhead.

Thanks Mike. Nice pictures.

Prapan

Thank you BaldEagle, Since I do not buy mounting plate from MVVS as I consider to save weight so I will drill the holes directly to the firewall and mount M5 scews (4) to the firewall using 1-1/2" standoffs. Another concern is that I have to mount engine in side way since my header looks like this....picture. I don't think I have space on motor dome surface which is enough for MVVS mounting plate..

This is a picture of KS header.

I will have to moiunt the MVVS similar like this one.

Prapan

But I don't think I will mount the MVVS like this picture on Composite-ARF EXTRA 330L 2.3m the guy in Germany. He put a lot of efforts on it.

Hi Pe, Is the drill holes (6) for spinner and 2-blade prop 24x10 of MVVS-58 the same as ZDZ 50NG?

If you give me the data I have to compare, I may be of help.
