1) Understand that because of the two stage rotor design, the only true pinion is the slant toothed gear on the secondary shaft. The gear on the motor is a pulley not a pinion. This has caused confusion with head speed calculators etc.
2) Understand that the original Manual, shipped with batch 1, has the wrong secondary pinion size listed as well as a list of incorrect motor pulley to main gear ratios. The kit as of date of this post is supplied with a 22 tooth motor pulley and 20 tooth secondary shaft pinion. For head speed calculators forget the secondary gear and enter 204 in the box for maingear tooth count and the motor pulley tooth count (22 as supplied) in the motor pinion tooth count box
3) Make sure you have the new front tail drive pulley H0101-S Z37, identified by four bolts seen when viewed from underneath, make sure these bolts are loctited (loose from factory!)
4) Make sure you have two extra shims HC-232-S in the head assembly, these were not installed in the some of the first batch but have been in all since.
5) Make sure your boom to blade gap is at a correct minimum. set your blade pitch at zero and measure the distance from blade tip to boom, this should measure at least 145 mm see video [URL="http://www.youtube.com/watch?v=7_qEj6G1o_8"]SAB Goblin: Important Announcement - YouTube[/URL]
6) Make sure to fix your tail servo wire firmly out of the way in the boom so that the tail belt cant touch it and cut through it, hot glue works well.
7) use a servo lead extension between the tail servo and Rx/fbl unit, fixed so that if the boom breaks away the plug breaks away and not your servo lead.
8) Some folks have reported the Jesus bolts at the top and bottom of the secondary shaft have been breaking in flight. these bolts are not shouldered type and you may wish to replace these with shouldered type, the Align T500 Jesus bolts fit snugly.
9) Sab recommend WD40 to lubricate the main gear for the first few flights. Listen to their recommendation, WD40 is not a lubricant and in this case is being used as a mild cutting agent to assist in creating a pefect mesh with the pinion. Some folks poo pooed the WD40 and used grease or triflow and now have a sloppy mesh. The WD40 does its job and then gets flung off, grease remains and creates a grinding paste which carries on grinding the main gear away.
10) Canopy placement... easiest way is to turn the head so that blades are at right angles to boom then lower swash as far as possible and then slide over.
Please add to list!
