The Dubro 150 sized soft mount will work if you want to go that route.

Jtec
 

I bought the Jtec for the saito 1.2 and it was perfect for 1.8 also.. :)

I have the dave brown 120 mount on the 180 saito...fits great !!

120FS-1024 Mount?
 

Is that the 120FS-1024 mount? I have one of these and the Saito 150 is much to wide to fit. Did you have to cut the mount?

Thanks for the reply?

they only make one 120 fs mount... right...so i guess that's the one !

Don't be afraid to spread the beams a little !!

THANKS!!!
 

Well, It fits like a glove! Thanks, I would have never thought to spread out the arms.

I can move forward on building the Chippie!!!

Just got done adding some re-enforcements to the fuselage. Should hold up to the Saito 150 alot better!

Thanks, Again outssider

Sheet metal screws are too soft and the heads will pop off in the long term

Drill and tap the holes for machine screws

RE: HELP!!! Engine Mount for Saito 150?
 

I found on the black fiber engine mounts if you use the correct tap size drill, drill it out then use a SOCKET HEAD HEX SCREW driven with a drill you can
drill the screw into the mount. Grind a small taper on the bolt screw before you start. Then be quick running it in and quickly reverse to run it completely out. There will be heat generated and the thread will be hot enough to mold around the screw. Do this several times until you are satisfied that you can hand screw the screw into the mount. I have never had one come loose as the mount acts like a locltite device. If you are concern of comming lose you can through drill before you power drive the screw. Then you can also put a nut on the back side.

Given you are working a 1.5 you might want the nut. DON'T use 4x40,, 6x32 minimum.

I tap the holes and use the tap in a V/S drill

The plastic holds onto the threads. even a sheet metal screw will not vibrate out.

Try a sheet metal screw in wood and it will back out faster than you can shut the engine off

My socket head screw is a 6x32 not a sheetmetal socket head.

why dave brown give this metal screws ?if it is not safely....i am thinking this metal sheet screws may be produced specialy strong for this mounts.had any body used this 120f dave brown mount and saito 150 with original metal sheet screws .???? help me please...

You will have to make your own choice.

For big engines I never use anything that isn't retained by a locking nut and or locktite. This means only machine screws on my plane.

Ask yourself one question. How confident am I that this won't come out and have I ever seen a screw of this type come out before. If so Why?

i am using original dave brown metalsheet screws over ten flight and everything ok...And vibration get lowest ...

and thanks
