The car was bind to the remote from the factory. There’s no manual but all you need to do is the usual by turning on the remote first and then the car. Much to my surprise all the switches are at ON position! There aren’t any clear marking so I didn’t know that. I put the battery in Transmitter and BOOM! It’s on. I plugged the battery in the car and the light came on immediately.

The body is the touring car style like the body from 1/10. I can’t quite make out what the car is it but I guess it is Honda Accord. It has windows and lights masking which is great. The body is very wide, even 2.5mm offset wheel can’t fill it. I tried putting it on WLtoys and it is perfect fit at least for the width, not body poles.

On to the car, first thing I notice is diffs are nice and tight, almost like ball diff level of tightness. Honestly I thought they would need a rebuild with thick grease. But I guess this is typical for Mini-Q because I bought a spare and it has the same tightness. Good job, Sinohobby!
Anyway, my car is going to get drift makeover so I’m not particularly concern about standard diff but I think you should know because I guess most people are going to use it for racing.

The included charger really works. The input power is 5V 0.8A. It charges the battery to 8.4V and 4.2V per cell. Actually I had a bad experience with small charger overcharge before so I was a bit skeptical about using the included charger. But this one will go with me everywhere.

Voltage output to servo is 5.02V. The servo is fast and precise. They claim that it is digital servo and I believe that it is.
Steering linkages and toe adjustment use 3.5mm ball head. Knuckles and shocks use 4mm ball head. Everything is adjustable down to wheelbase.


The Drive With Stock Setup
It has good grip through tight corner with slight lift off oversteer. The car changes direction without the weights to fling it out or to do anything unexpected.
I don't do much TC so I can't comment much further. Let's talk about drifting with this chassis
The only thing I did was changing the wheels and tyres for drift tyres. But this one is a bit special. The wheels are Atomic AMZ 2.5mm offset and the tyres are Drift Street (DS Racing, yes, that company that make drift tyres for living) F2 compound. They are bloody difficult to find so I don't use them much in case I wear them out and can't find replacement. Anyway let's continue.
Turn in is as expect from open diff all round, a bit lazy and not sharp. Once it start to slip it can maintain the momentum all the way without shooting the car out off the line. Transition is, again, lazy from the diff but it doesn't do anything unexpected. It cope with constant direction change very well and can carry momentum without shooting the car out the other way unexpectedly.
A very pleasant drifting experience indeed. Even with stock setup it drifts better than a fully modded Mini-Z AWD with gyro.


The good
- Reasonably price for a competition level car.
- Available both as RTR and ARR.
- Carbon fiber chassis, very strong and light.
- Metal swing shaft (CVD/ dog bones)
- Full ball bearings.
- Fully adjustable camber, toe, ride height and spring tension without the need to buy additional parts.
- 3 Wires digital servo (again, I take their word for it... the servo is super smooth though).
- Compatible with some Mini-Q Q3 to Q6 spare parts, most importantly compatible with spur ger for adjusting wheelbase.
- Compatible with Kyosho Mini-Z AWD parts such as differential, swing shaft, wheels. Also presumably compatible with Mini-Z AWD DWS springs too.
- Compatible with Kyosho Mini-Z Autoscale Body from 90mm to 102mm wheelbase.
- Low Voltage Cutoff of 2 in 1 unit actually works.

The bad
- No manual or standard setup guide included
- MAJOR DESIGN FLAW! Rear toe change when suspension move up and down
- Not very well build out of the factory, some screws were not properly tighten, strange spacer at the rear that bend the upper deck upwards. And most severely the car doesn’t turn left and right equally. Lucky all of this can be fixed by rebuilding the car.
- Some quality issue like bent body catcher, loose ball cap at suspension arms generate a bit of slop but not too severe.
- Very short servo arm but very long steering knuckle arm so the turning angle is very limited, again this can be fixed easily by replacing servo arm. But out of the box it's much worse than Q3 to Q6.

Final verdict:
This is not a car for beginner. You need to have some tools like hex screw driver to rebuild the car. Also you might want to take a note before take everything apart because it doesn’t have manual or setup guide. Even though the build quality is questionable and design flaw at rear toe, the car itself is fantastic. Once I sorted out the problems the performance is stable and I dare say it's miles better than Kyosho Mini-Z AWD.

Hard question: Q7 or AMZ?
Tough choice! Choosing between these two is like choosing between Serpent and Xray. Just go to your local track and see what they run there. Take a look at the competition you want to enter to see which chassis is allowed. But for pure fun with tinkering with setup I wholeheartedly recommend the Mini-Q Q7.

----- Modding/Fixing Video Library ----------------------------
Q7 video will be published once every 2 weeks. It's actually a new video each week on my Youtube channel alternating between Q7 and other cars. I'll try my hardest to make it happen until I run out the parts or the things to do.

1st Mod: Servo arm. The biggest offender of this car for drifters.

Now that the video is done, this body will live happily ever after on my shelf of honour alongside my Tamiya Mini 4WD collection.

Finally the final verdict and the end of off-the-shelf parts drift project. Enough videos for now, I'm taking a break to finish my thesis and prepare for defense.

Ya reckon??

Sino Hobby seem to have decent wee cars, very similar to WLToys 1/28 scale but more on-road and more hop-ups.... https://www.facebook.com/rcminiq/

Those are drift tyres but the chassis loos like very competent and adjustable touring car.
I guess the price would be the same as TR-Q5OP and include both grip and drift tyres.

Sinohobby have been making good and cheap 1/27, 1/28 cars for a while now except the TR-Q5OP, that's too expensive for what it is.
Q3 (Turnigy TZ4), Q5 (TZ4 Drift) are widely popular. With this new one with double wishbone suspension it should rival AMZ especially if the price turn out to be what I expect. It'll be in the direct firing line of AMZ.
But if anyone want DWS for cheap... WL is the way.

I hope this small scale will become more popular for years to come.
