I've used this setup and it works very well (all but the top A arm mod - so far). Even on a green track, the car was great on its first shake down run; however, I had some minor problems with the back end breaking loose coming out of tight turns. Two possible causes: I found the front droop was uneven which I have fixed and I too messed up with the different diff cases and the rear diff was once filled with 600K oil and I may have not gotten all of it out when I refilled it with 50K. Anyway I haven't had the car back on the track to see if the problem is fixed. However this Hybrid setup won the big Serpent Challenge race in Brownsville this Spring. It was by far the best ECO car at that race and why I bought the MGT7: no option parts plus I had access to the driver and his setup! (BTW tires were S5 F and S3 R for the race I was using S5 F/R)
.
I got the car back on the track this weekend and the problem was better but still loose (hot green track). I double checked with the racer Sunday that he really did have 50K oil in the rear diff - he did.. Since he is a very good driver with better throttle control than me, I softened up the ESC so the acceleration had some expo in it and the car was much better. I still may try some lighter diff oil; however, I want to make some other changes he suggested first such as reducing the front droop that I had increased to help weight transfer to the rear in an effort to stop the loose on power condition. He also said to set the ride height at 10mm (F & R). With the temps at well over 100F, all the cars were loose even on a prepped track.

Has anyone tried using a carbon fibre chassis instead of the alloy one?
If so what thickness was it ? Any improvement on a med traction track?

Who makes a CF chassis for this car?

What kv motors do you guys use for racing?
Ive been using a Trackstar 2400kv 18/44 which is fast , but am close to dumping with 6000mah batteries if i do more than 1 lap of warm up for 6 minute races.
Just bought a Tekin 2250kv but haven't tried it yet going to try 19/44 anyone else use this motor?

The 2250KV is a truggy motor it might be a bit too torquee for on road. I'm running the TEkin 2050KV buggy motor and I just turn down the amp draw on the ESC and I'm running a 19/44. Others are running the big Tekin Buggy motor (2650?) but they just turn down the throttle end point so they don't use all of the motor.

ok cool
I've recently finished fitting my SNR graphite chassis ,id recommend it to any GT7 owner as it shaved over 100g in weight over the alloy chassis and running it back to back the car feels like its on its tippy toes , and responds better to changes
awesome upgrade!
Steve at SNR has great after sales service and is easy to deal with.
Now for some graphite shock towers.

We've been racing with 2250kv Tekin T8 (me) and Trinity 2300kv (two folks) on our track with no issues. My gearing ratio is 21/44 and I've just bought a Trinity 1950kv to try.

We had started racing with Tenshock 2650kv in our track (19/44), however, higher kv motors are power hungry and you're forced to use bigger batteries and with higher discharge.

In our track, the sweet spot seems to be 2250-2300kv @ 4S but I'll try a motor with more torque so as I can try to preserve my batteries

p.s.: 2050 has more torque than 2250

higher kv motors are more power hungry and offers more RPMs with less torque
lower kv motors are less power consuming and offers more torque with less RPM

with the correct gearing ratio you can make different motors reach equivalent top speed (if the car project allows, of course)

Ive been using 2400kv motor with 6000 mah Thunder power lipos
19 / 44 , i run on a large track 6 minute races.
I can only do 1 lap of practice and i nurse the car half way through the race to conserve battery power, then ill finish the race with out dumping.
Ive bought some 7500 mah Turingy graphene packs to sort the problem out
anyone else tried using these packs?

I also bought a Tekin t8 gen 2 2250kv gearing it up 20 /44 but was no where near as fast as the 2400kv

have you tweaked punch/torque control in your esc?

yea I've adjusted the speedy
but the 2250 kv just didn't have the zing of the 2400kv
Im buying a 2500kv orion motor this week so i don't think power is going to be a problem combined with the 7500mah i reckon it going to be a good combo.
The track i race on is big and open so I'm on full throttle a lot.
