Also, here is some cooling plan.
Due to the hi-profile designe, I put some form for help to the cooling of the engine head area.

Recommended to ues the long length plug heater.
It is real deep....!



I'm use Rapicon 30% fuel fo my 175 engine. This fuel is way better than other glow fuel.
This Rapicon fuel is significantly better feel compared to other fuels. At 2013 F3A world championship, Paysant-Leroux Christophe was used it.
will update soon... and see you at the field.
