CRF is Team Orion's proprietary Swiss technology and this is one that we like most because we believe it brings advantages over regular technology and we will keep pushing and developing the CRF technology in the future.

Adrien Bertin the Team Orion nitro engine R&D manager, worked for several years at Sirio and was also developing products there. The Alpha line using standard engine technology, can be considered as the finalization of his previous projects,

CRF = high quality engines using unique CRF technology
Alpha = high quality engines using standard technology with competitive pricing.
