Na, your cool glad you asked now instead of later. It is a shorter main shaft and the linkages to the head are different. This is the newest fad on fbl systems. With a shorter main shaft you drop the head lower to the center of gravity and making a more stable heli while in 3D flight. Unfortunately I have a fly bar system so I will not be able to use the main shafts. On the other hand If I keep them then I will sell them at retail after I get back to the states. It is a two pack with two sets of jesus bolts. at least thats what it looks like. Any takers, I will be in the states in 34 days and a wake up so on Day 35 I will be back in Ohio for about 10 days. Retail was $11 and some change.
The Align head is about $36 USD plus you need a 3 axis gyro (i.e. 3GX or tarot zyx) and fbl main blades. you could be looking at [starting] just over $100 USD to get started.
