Chapter 1: Crash Cost
First the 4 things that always/almost goes in any crash on the Hornet 2:
1) Main Shaft
2) Brass inserts
3) Brass Insert Screws
4) Main Blades
5) Conical Gear
6) Carbon Tail Drive Shaft
7) Tail Bevelled Gears
If we do a simple addition....Crash cost = $130++ rite? No
Not if u have the following:
( ranked in order of 'must-have')
1) Ms One Way auto kit---$46
2) Titanium Tail Drive Shaft--$15
3) Some Extra 2mm hex screws
4) Extra Carbon rods......
5)!!! Must Have: GWS micro Pinion Puller----$14
It's worth the extra $$$
1)MS-OneWay: Switch out the metal cross pin for a 1mm carbon rod..... file the rod on the ends so that it'll not fray when u push it thru the metal sleeve and the main shaft..... This way... when your blades strike something, your carbon cross pin would snap first..... In a crash, u'll save the tail gears, conical gears and ur tail drive shaft.
Also... even if u do not do this mod, with the oneway, ur conical gear, tail gears and shaft will stop spinning once u cut throttle..... lNo more stripped tail gears! .... In the worst scenario, u'll only have to change ur conical gear
UPDATE: This carbon cross pin trick is only good for mild flying... if u're doing acrobatics a better choice would be using body pin clips from R/C cars.... These clips can also be sheared... but chances of wearing out the one way sleeve is higher. It makes for easier maintenace and does away with the CA....

2) Titanium Tail drive Shaft
For $15, u will not have to worry about snapping ur tail drive..... ( I know i used to destroy mine really fast cos i had the habit of piro'ing too much ...)... Also, the stock carbon tail drive will wear down and twist and fray which causes tail wagging in flight..... a point which most people never realise.....
How will this titanium upgrade help in a crash?
Let's say u stripped ur conical gear and ur bevelled tail output gears... On the stock carbon dive shaft setup... u'd have to painfully remove the gears .... most of the time, u'll end up ruining the stock carbon shaft ends as well...... and the bearings are a B@#$! to remove from the tail drive..... With the titanium shaft, u simply use the GWS micro pinion puller and the gears can be removed easily everytime... becuase we're using epoxy to attach them on.. not CA....
Also.. the stock carbon tail drive shaft is under 2mm .... so even if u manage to acquire 2mm rods.... u still have to sand them down to fit the bearings snugly....
Update: An even Cheapo method..... if u do not want to buy the titanium drive shaft.... when ur'e done Ca'ing the bearings in place on the tail drive shaft, coat all the exposed areas of the carbon shaft with CA.... this will reduce the the amount of twisting of the carbon fibres in the carbon drive shaft.... and will reduce chances of u losing the tail in pirouttes..... |
