If you have a firewall mounting situation You should use a Hyde Mount. The Yamada (YS) Super mount is designed around the rails already being built into the model like this photo that I attached.

The Hydemount attached directly to the firewall. The standard YS mount would be the AR type. I recommend this version. It requires a nose ring mounted in the nose of the fuse. If your model doesn't have molded nose and the front cowling is removable then you need to pick a Type A mount. I don't really like the ARI style mounts with the nose ring incorporated. There are heavier and require a heavy strong firewall to keep the engine on the same thrust line. The type A mounts "don't" require a nose ring...but I prefer the engine mounts with them....I choose the AR types for my use.




The gator RC mount you are showing may be a solution is the model has a cowling in the front. See the Cowling is not strong enough to support the front of the engine.


I'm not familiar with you model 10x.....perhaps I can help you choose the right Hyde mount for the job.
The only 10X I know is my JR radio.
