Breaking News! P28GT

We have known about this car for some time now, and have had an exemplar inhouse for testing for a couple of months.

The car are similar to the old P28 Pan Car, but some differences are to be found.

  • Black FRP chassis
  • Disk damper setup
  • T-bar
  • Made for regular plastic bodies!
Other than this, it is basically the same car as the P28.

Before testing, we went trough the build of the test car supplied to us.
Everything fits very well together, and the looks of it are great. It just looks mean!

The T-bar is specially made for this car as you can see in the pictures. It is made of carbon fibre, and we got two different hardness bars to test.

The front suspension are the proven sliding kingpin style. This makes setup very easy, and it is race proven. You can use a lot of different springs to make it suit your driving style and grip levels.

The steering setup is smooth. The small servo used here is a Futaba S3114, but other alternatives such as Futaba S3154 can also be used.
It has a very good steering feel, and we can conclude that the guys doing the design has done a good job regarding ackerman settings.

Another trick this car has up its sleeve, are a very very wide front end. This is something we like very much. Going this wide, you can run lower offset wheels and really minimize the scrub. This should give you an advantage over the regular mini-Z type front ends where most people run extreme amounts of scrub.

The chassis plate are as mentioned earlier, made of FRP material. This gives some interesting flex characteristics.

It uses a regular MR-02 or MR-03 card, that most people know and love. We have not tested it with VE electronics, but I am sure this will be a potent combo.

Testing.

Initially the car was a bit twitchy, but after some small setup changes it really came alive.
The grip this car offers is extreme. The flex of the chassis does most likely contribute to this.
We ended up with some small radio adjustments to get the steering feel perfect. -4% on steering curve was all it took to calm it down.

The steering feel is very good, and it really has a precise feel to it.

We tested the car with a lexan pan car body, and also with a Mosler hardbody. The hardbody adds weight, and this helps in calming thinhs down, but a lexan body can be extremely fast on this thing also.

The car are shood with our tracks favorite tires, and they offer extreme grip. On a regular Z, most people struggle a bit with overheating front tires. On this car we are not! This is due to the reduced amount of scrub!

Testing has been done over m
any many hours of driving.
The setup that ended up beeing fastest at our track is as follows:
Soft T-bar
One disk on DPS. Over. Silver Reflex Racing spring
5000WT Kyosho gear diff grease.
Top shock oil: 500 CST
Top shock spring: Kyosho stock
Top shock preload: 1mm
Front spring: PN White MR-02 Lowdown. Preload until 0 droop.
15000 WT grease on king pins.
Toe: 0
Offset front: 1 (Equals 3 offset on a regular Mini-Z)
Offset rear: 3
Additional ballast: 6 grams center of the chassis
PN 33T motor.
Mosler body.


Basically what we can say is. We think this is maybe the fastest option chassis Mini-Z out there.
Things are kept simple but effective.
If you have raced Mini-Z before, you know how to adjust the setup on this thing. It really is intuitive.

So. If you club rules lets you use this type of car, you really should consider this one. Maybe one of the best option chassis out there as we speak.

  1. Thanks Rune! We have been running the GT with the VE electronics at our test track for a while now and it does run strong. /Johnny, Lajf Racing

    1. That I can imagine.
      Try the car with the white lowdown PN springs. Preferably an old set, and remove some dampening from the rear end. My car had overdampened rear end and was a bit lazy befoee I removed one disk.
