Here is an example of SMR Pty Ltd's hardware for the R250 with alloy engine plate, all hold-down bolts and integrated cut out bolted to the rear of the plate enabling the model builder to position the tank outlet very close to the rear of the engine for best results.

Installed in a model the engine plate provides a firm connection between the engine and the model frame, and a great mounting point for the shut-off between the engine and the tank.
