These parts are for 16a and some of 16b

If you’re planning on adding an FMA sensor and if you want a platform for it, this would be the best time to add a second part 391 & 394. (Gyro mount).  Luckily I ordered a second set before I mounted the tail boom.

CRASH NOTES

In most crashes the tail boom will bend.  I've broken the tailboom supports once.  For some reason the crashes afterwards the supports seems to survive. 

Keep a tailboom, supports and tail belt as backup.
