That is a nice motor mount if you use a shorter can motor. However, longer "XL" size cans may be a tad too long and interfere with the suspension arm, especially if the motor wires come out the back of the motor (instead of out the side of the motor).

If that is the case, you will need to design the motor mount so the motor sits higher up to allow suspension arm clearance. Unfortunately, this may cause pronounced flex in the mount, especially when landing from jumps. This flex will affect the mesh and mess up the spur.

In that becomes a problem, I recommend finding a way to support the other end of the motor via some type of bracket. I actually used a thick piece of very firm rubber under the motor as a support and it seems to work well.

A single Titan will be a bit overworked IMO.
