GRC front motor conversion kit for TRX4 (read notes)

Here is me playing with it out of the box. I removed the sound because well copyright music in background. Besides, who cares 40 minutes of rambling. here are the cliff notes
- Will need some fitting if you use aftermarket parts
- Its noisy even in finger spin. wonder how much grease will silence it
- driveshaft has tight joints. bueno
- 2 bearings are loose. holes too large. maybe by design? illogical tho. bad machining? probable.
- only works with the stock 45t spur gear and NOTHING else. you can see me fiddling until i realized that
- motor can be "hot swapped"
- i recommend a 540 motor over the 550. way more space and flexibility
- gears had no packing oil. slight surface rust!
- Most of the provided screws are too short. Many of the provided hardware barely thread in. BAAAD. Consider replacing with +2 or +4mm for many of them. Cause if you strip the alum, you are done.
