Help With Motor Mount / Stand Offs

I've a Art Tech Mustang that I'm trying to make / use a different motor mount for but am struggling to find the right thing / size that will work.
The motor is a turnigy 35-30, I got one of these motor mounts
http://www.giantshark.co.uk/motor-mo...-p-404918.html
But it's too wide as the space I have is little more than about 40mm

I have 2 mounts that come with the motor and was going to try and get some stand offs like these but ideally approx 38mm long
http://www.hobbyking.com/hobbyking/s..._4pc_30mm.html
and put them in between to make a mount similar to te otehr but smaller but I can't seem to find anywhere that has them in stock, does anyone have any idea who in the UK may stock them ???

The alternative is I try and use something like this mount instead
http://www.sussex-model-centre.co.uk...xd.asp?id=1192
How would I go about fixing that to the actual plane I'm lost for how I'd do it, I've made a plate out of ply that I can just screw the other flat mounts to but can't see how to get one of these to attach??
Any help much appreciated!!

I bought aluminum tube and built my own standoffs for a glow to electric conversion I did last year. They work great and were very easy to cut. Most LHS or DIY stores should have aluminum tubing.

May give you an idea how it looks.

No need to overthink this. Go to the hardware store and buy some nylon stand offs of the appropriate length. Fine tune by adding washers.

Take a piece of 1/4" sq balsa. Chamfer one edge (cut off the corner ata 45 degree angle). Cut to approximate length and glue 4 together with the chamfered edge in the middle. Run a drill of appropriate length for the bolts you will use down the hole in the middle (use slow speed or your fingers). Line with aluminum tubing (optional). Cut to proper length, and use as stand-offs. If desired, box the standoffs with thin ply or balsa.

No need to go buy standoffs.

I ordered several sets of spacers from the folks at Aluminum Spacers. I tried the nylon ones from the hardware store but had some stress cracks form on one of the tube walls and lost my confidence in them. The aluminum ones were cheap and they shipped asap. I bought a set of 3/4'' standoffs and bought a longer set in case I needed to cut my own to fit.

Nice work.. but unless you have everything absolutely balanced don't you risk vibration... I'd add a ply box around those stand-off bolts (effectively providing an anterior firewall for the X-mount), to dampen resonance.

This is what I did to electrify a Big Stik. Double mount to save existing nose gear setup and use existing blind nuts behind firewall. Dave

Mine are made from 10-32 threaded rod, hex nuts, fender washers, blind nuts and PEK tubing from Lowes.

Buzz, nice deal but a little long for just 4 bolts for me. Either a mid plate, thus shorter spacers on an aluminum tube box mount to eliminate vibration. Zee

Thanks to all for the suggestions, Buzz yours looks like the one that'll work best with the set up / space I have, did you mean pex rather than pek tubing ??
