Team Orion Marathon 1900 XL RX packs
Team Orion have developed an entirely new cell to create the largest capacity receiver pack, the Marathon 1900 XL. With the use of powerful digital servos in addition to larger and heavier cars like truggies and monster trucks, higher capacity receiver packs have become a must for nitro fans and only top-quality cells should be used to avoid loss of signal and radio glitches. Maximum capacity is a key advantage in racing and only Team Orion Marathon packs combine extreme capacity with incredible performance. Available in both flat and hump pack configurations, they also come in 1700mAh versions and with a choice of JR or BEC connectors.
