The bolts then go right through the cross mount and plate with the countersunk heads sitting in the recesses in the cross mount. This spreads the load into the mount plate, and makes it bullet proof.. A really neat idea.
Dude! That sounds exactly how I'd like to set mine up. Any idea where I can look to find the pics/info?

As i read it it's exactly as per your description.... He just epoxied on the X-mount on and re drilled the two holes that didnt align. The x-mount re-distributes stress away from the area where the holes are. Plugging the old holes in itself is really not achieving anything very usefull because the glue in the hole doesnt add any significant strength.

I'm sure this mod could be used instead of motor box glassing for those who dont like the mess and fuss of working with resin and glass. In fact I very much suspect it would be stronger than glassing.

just do yourself a favour and get normal sized screw drive for cabane struts... all my hands was painful from doing that with tiny tiny screwdriver....

i have almost finished assembly, i decided to go with thrust40 and added hacker x55, and mg65 wich i had lying around... i guess i added a touch of too much epoxy on one side of firewall and now my motor is not 100% flush with firewall... should i just dremel it out? or fly like that? there is like 2mm gap between motor and firewall..

If the motor is sitting skewed over then you really need to fix it otherwise the stock thrust angles will be out of kilter which could really mess up the handling..

The epoxy is probably just catching the edge of the motor and you might not need to remove very much to allow it to sit flat.

You will have to work hard to have it ready for the weekend, the AMR needs a few more hours spending on it than most other ARF's

Weather has gone crazy here so no idea when i'll get the chance to fly next. 9 days ago we had the hottest March day ever recorded in these parts at 23 C (73 F), no wind, perfect conditions (dare I hope for a epic summer?).
Today I wake up to freezing temperatures high wind and 6" of snow, had to dig my thermals back out and scrape the ice and snow off the car

Remove the circlip and test fit your T40 again before resorting to removing epoxy with a dremel or iron.
