helidirect 400tooth belts
(gotta love that odd-even pricing strategy lol)
best belts i have used so far. never had problems with jamming, etc. it survived major crashes and doesnt even get frayed. UNLIKE align belts....my new XL belt failed on maiden flight and caused a minor mishap long time ago. i bought a couple of these because they were cheaper, i never even had to use my extras because i still have the first one in my heli and it's like new even after my two last failed roll attempts.
