Do you have any video's of them running.
Always like to check out things that I haven't seen before.
Thanks for posting.

nutechracing usa had one of these once (as did a couple of others)...it had many issues with reverse, drivetrain etc ...here is their summary
"Things That Broke within 1 1/2 tanks I was able to run through it:
Melted front and rear differential boxes
Went through 2 sets of differential bearings
Stripped 5 different steering servo arms (found one place that stocked the arms and I ordered them in bulk lol)
Broke reverse gear twice
Broke all 4 body mounts on first light rollover lol never saw so many parts come off in 1 stinkin roll over
Threw 2 front drive shafts? couldn't figure that one out lol they just pop out of the cups and fall out lost 1 in the snow of my driveway and almost went through my snow blower lol that wouldn't have been good.
Lost various screws mostly the screws that hold the upper a arms to the hubs.
Cons after running it:
Steering is way to stiff, I played around with it until I was blue in the face all it does is make this annoying clicking sound but any light impact to one of the front wheels and it instantly strips out the steering servo arm then your draggin it back lol, I had to find my old dog leash when I ran this so I could pull it back when it broke.
Gears are much nosier then the FS with steel gears sounds like the motor is ready to blow up but its just the gear noise.
Cant find much for interchangeable parts
No dual steering setup even though they have another tab for a 2nd servo arm to connect but the servo tray is designed for only 1 steering servo would have to make a whole new servo tray and battery box setup for it to run dual steering servos.
Pros after running it:
Love the thickness and style of the chassis very stiff and well designed.
Love the solid alloy roll cage never saw that before I think it will with stand some serious rollover just need to find some body mounts that will take the abuse the cage can take.
Enjoyed the stock gearing I think its great right out of the box tons of bottom power and ok top end for a MT.
The CY motor was great lots of stock power with the gearing, started every time within 2 pulls, factory carb settings were almost spot on didn't have to mess with them yet granted I only have about 1 1/2 tanks through it.
2.4 Transmitters were pretty good never had any glitches or range issues and it has a ton of nice options including fully adjustable throttle and brake ARC.
Shock towers and shocks seem durable I will know more this summer when I can spend some more time rebuilding the MT so it will go longer then 3 - 5 minutes without something breaking on it it but they seem pretty durable I like the 2 per corner but they are very stiff stock for 2 per corner.
All in all it has some great features but as a whole I would say it failed beyond the point of trying to work with the factory to make some serious changes, I certainly wont pursue this right now or in the near future, I will most likely keep the MT for a conversion project but it will be something custom and make the buggy pretty for hanging up in my office but other then that I feel it was a waist of money in its current state and if nothing else at least I was able to do it before you guys waist your hard earned money"
and another owners comments
I have this same car as your testing and your right just a little bump and the top gear box ears snapped off and transmitted the energy back and broke the rear gear box shock tower posts off as well.
I have also stripped the front and rear gears completely and didnt even finish 1 tank of full.
1 front outer axle cup snapped (no 4wd only 3wd)
2 shock towers broke off (front& rear)
3 center diff case cracked on right side forward gear work (no reverse)
4 blew tires off (glue no good had to regule 4 times)
5 steering servo bad
6 shocks arent filled with anything (no oil)
7 body mounts broke off
8 they sent wrong and broken body
9 missing controler in package
10 exhaust has a crack in it from factory where pipe meets rear can
11 spark plug snapped
12 we took this completly apart and welded the diff gears together so we could at least drive it .
I made main supports for the top of both front and rear gear boxes that attach the shock towers to gear boxes .
I made main supports pushing inwards on front and rear outer shock mounts and
1 main support from front shock tower to main chassis servo plate to absorbe the impact of a basic bump on front end.
The roll cage is a major flaw in design because if you notice if any impact in front or rear of car all of this energy it transmitted into the gearbox shock tower mounts and they will snap off very easily
I also made additional main supports and raised the roll case to cover the spark plug supports go to and connected to bottom chassis to help protect roll overs .
Every mod I have doen is working great .
The company i bought this car from told me basiclly to get stuffed and i would have to buy new parts.
This is wrong in every way I only have had this car for 1 week before i had a chance to play then it broke first time out and its been down longer than I have owned it
Here are some pix
I have contact another supplier and trying to get all of these parts replaced warranty

Those reveiws definitly changed my mind about even cosidering this, sounds like for the "basher" this would be one giant headache. I will pass.

This is why FG must continue!!
Half a job may as well stay on a shelf!
Perhaps they're prepared to listen to ideas on R&D?
KM 'clone' Bajas have come on big time in the last few years.
Previously many would buy them as cheaply as possible and replace half of the contents within 6 months!

I don't see how the above damage was possible,i ran mine dead on full out into a large pine ,it cheared the front diff case almost off screws gone but case fine,bent a bit the front top plate,did not even bend front bumper,or frame plate,15 minuts later she ran again!Could not believe my eyes ,very little damage ,35 mph head on collition and she lived!
He must have had a bearing failure,i never did but replaced all major ones,abuse any machine too much and it will break,mine i bash and bash but try not too much,i broke my alloy KM baja nose frame off from reapeated high impact jumping,fun but not good for my babbies!

I considered FG but saw that there diffs fail too much,arent as wide and tires too much rubber just my opinion,(then i also run a Redcat mt wow that is rubber),compared to SY very same design but beefeir very smoth and very reliable and not expensive as every single part is available,i have the factory parts list and order direct.
I will make a video but till then see this one.
