This STE heli is a real Frankenstein, but still it is 80%+
Minuature Aircraft stuff.
And, 99% of the new stuff came from Ricks’ www.ronlund.com

My Setup – rarly imitated, thank god.
MODS and Parts:
- I made
a aluminium “L” bracket for the servo tray. The kit has a pair of bent L-brackets that hold the lower
portion of the tray to the front bulkhead. These brackets tend to crack after time, so I machined a
bracket out of solid Aluminium on a Bridgeport milling machine. I tapped the holes, and there is no way
this thing will crack!
- I didn’t
want to buy another swashplate, so I milled out those slots in the plate
that allow ball link pliers to be used.
MinAir is now shipping plates that have this done already.
- See
the STE Pics page to see the Bergen frame
changes
- I use
aluminiun screws and nuts wherever possible to save every gram. I try not to use washers and such when
not absolutely nessesary. Over the
years of building and fixing these, I learned what things loosen, and
slip.
- I use
a big lower bearing on the mainshaft.
The Fury uses 4 bearings on the shaft, but there is no good way to
use a lower bearing on the SE, so I have to do the next best thing. For now, I use a 50% thicker bearing on
the lower, and dual bearings on the upper. I am finishing up a CNC bearing block that allows using 2
regular bearings, or one thrust+radial.
Since the elevator swingarm is not there, there is plenty of
clearance for any bearing(s) I want.
- I use
a Bergen Torque Tube system. It
has one universal at the front, and uses a solid connection at the
rear. It uses $5 tubular arrow
shafts, and they are easy to change, and a LOT cheaper than the MinAir
carbon shafts. My tail drive also
has almost no wind-up; even the carbon system on the Fury has some
twisting, but the arrow shafts are MUCH more rigid.
