T-Rex 450 tail mechanics
This little piece of CNC art is the Microheli Precision Tail Pro SE V3. When you absolutely, positively have to remove any slop in the tail, accept no substitute
The only slight problem with this particular version is the screw hole for the ball link - it seems to be in some alien thread as yet undiscovered by human science. I think the spec has irrational numbers in it. It's still just aluminum, though, so it rethreads easily. Alternatively, you could just fit a Rex size ball link end on your tail pushrod. Align stuff should be no problem - they seem to hang their balls on the same thread as Esky, so you could recycle the ball and screw from your stock tail.


T-Rex/HDX450 feathering shaft
Requires shimming at blade holder roots, and bolts to replace the nuts on the Belt shafts. Creates more space inside the blade grips for Align blades, easier to tighten evenly, no more hunting for extra slim and deep box spanners. Better material and less likely to bend.

T-Rex XL 116 mm stainless steel main shaft
Put it in upside down so the waist doesn't ride in the bearing. Grind a small flat for the collar grub screw. Turn all servo links down to restore your pitch settings and say goodbye to the spool-up boogie. Reduces vibrations and should handle stress better than the original part.



King II main shaft
Same as T-Rex shaft: insert upside down, turn down swashplate links to restore pitch.

Align 315 Pro blades
Reshape the blade root to create clearance for the feathering shaft. Use two 1 mm shimms to fill up the blade holder. Lighter weight, better performance and more durable than Esky woodies. Once you try these, you'll never go back.



HDX Fiber FRP 315 mm blades
Use two 1 mm shimms to fill up the blade holder. No reshaping necessary. Extremely durable blades that perform well on the Belt.

T-Rex flybar paddles
Drop-in fit. They make control inputs less spongy and look great.

T-Rex new damper system
Split along the middle and these are a drop-in replacement of the rotor head o-rings. Much stiffer, they reduce slop in the feathering shaft and should be just the ticket for fixing those incurable tracking problems. The T-Rex o-rings work too, but won't be anywhere near as stiff as these.

T-Rex 450 canopy
Perfect fit. Some versions may need a little cut on the side so they don't contact the front servo rod. Provides more space for mounting the battery forward, which is just what the Belt needs. Looks good too.



T-Rex horizontal and vertical stabilizers
That's fins to us simple folk. Drop-in fit. Horizontal comes with its own mount - the original Esky boom mount has the correct screw hole spacing, but the new fin is shaped to grip the boom. Original mount still in the picture because I was too lazy to remove the boom and didn't have the heart to cut it off.



HDX450 aluminum skids
Legs need new holes outside the existing ones, and I couldn't find a suitable drill bit. The skid part and rubber holders are a drop-in fit on the Esky plastic legs.


So, come on, you compulsive modders out there - chime in with your own modifications and upgrades. I'm sure there are other parts that could be made to work on the Belt. Oh, and for those of you about to ask why not get a T-Rex or HDX450 in the first place: It wouldn't be a hobby if it had to make sense

That is some cool Beltrex! Now I know where to come when I'm ready to upgrade.

Ah, excellent. I was just on my way over to repost that list, but I don't mind someone else taking over the updates

[psilo]

Yep some great info there.

In particular there are a few must have upgrades there, the t-rex main shaft (so much better than the bent from new esky!), the helimax 400 main gear (much better again and can survive crashes!) and the align 315/325 blades (woodies or fiber).

These should definitely be installed when you next need to replace your esky one.

Just a note though, the helimax 400 main gear needs the bearing pushing through around a mm to stop it binding (push it 1mm up towards the head as it is flush)

ANOTHER_FINN!!! YOUR HERE!!!

SWEET!

Your Credentials are at the top, Please carry on LOL..

[another_finn]

Can't have all you wascally webels ruining Esky's spare parts racket all by your lonesome, can I?

Here's some gratuitous glamour shots of the (wanna)B-Rex before the final round of upgrades. The parts should already be on a plane... Can I still keep calling it a Belt as long as it has an Esky tail boom? Oh, and the motor and ESC, at least for now.

[DierWolf]

Almost lookin nicer than a Rex Self!!!

i gonna have to do over my beauty shots

I am so happy I found this area!! Great tips on the parts as the Belt CP parts are hard to find locally. But here is my question I have the E-Sky aluminum head and the feathering shaft is a rod that is drilled and tapped like the T-Rex but it bends like butter, it needs 6 shimmies to get it tight and hold tracking and is only available with the grips. There is another shaft that comes in the kit but it is 7mm shorter. O and once you go to these grips you no longer have to trim the roots off the blades.
