6.34 should have more grunt out of the corner and less top end, whereas 5.4 should reduce grunt out of the corner but give more top end.

On a short track, Boost might not come in, soon enough, so I would look at a smaller pinion.

BagofSkill · #**322** 20-08-2009

all I can say is that if I run a 22t pinion and 30 Boost I get a car that is very soft and smooth on acceleration (by comparisson) and great top speed. But it's never going to spin the wheels on acceleration.

If I run a 26t pinion ans 15 Boost I get a car that has MASSIVE punch out of the corners and off the line, and pretty good top speed. This has the ability to spin all four wheels on carpet if you abuse it.

The track is small like I said, 20m (65ft) straight. So ultimate top speed isn't an issue, but rip on the infield is.

Do I have a problem or am I going down the wrong path?

DCM · #**323** 20-08-2009

maybe the 22 is just too smal a pinion, and the motor is over-revving.

hey fellas where can i get v200 software.

BagofSkill · #**325** 20-08-2009

With the 22 pinion (82 spur / 1.7 IR) and 30 Boost my temps hit 70 at the end of a 6 min race. If I run a smaller pinion temps drop, if I run a 23t pinion temp goes up to 75 and if I have to drive aggresively in traffic even higher which can cause the motor to go soft towards the end of the run.

Take the setup you like best and post the setup for me to see.

How long is the straigt away from inside corner to inside corner? Got pics?

BagofSkill · #**327** 21-08-2009

Hi Randy,

Picture of the track attached. It's 15m (49 ft) from apex to apex on the straight.

Setup I like best is:
DB 0
BS 100
NW 10
TP 3
VC 2
PC Off
Boost 15
CL Off

FDR 5.6

This gives nice punch out of the corners but I could do with a bit more top end.

If I go up on Boost and higher FDR I loose punch but gain speed.

Theoretically, if I leve gearing alone will high boost give me less torque and low boost give me more torque?

Thanks,
Chris.

Is there new software due?

BagofSkill · #**329** 21-08-2009

New software is out but you have to email Randy and ask for it.

mikeyscott · #**330** 21-08-2009

Turbo feature sounds interesting, but changes the gearing etc. Need to do some research for my 2WD and 4WD both running 7.5 motors

Randy p · #**331** 22-08-2009

Chris, a few questions:

What is the motor timed at?
Can you hold WOT from the corner getting onto the staight away?

In general when you gear up a spec type motor you can use the torque if it's there. But if the motor runs out of torque the only way to get more speed is rpm. This is why timing comes into play.

BagofSkill · #**332** 22-08-2009

Randy, the motor is a Redline 13.5 timed to 0 on the can.

The corner coming onto the straight is a little too slow for WOT. You can make it work by it's quite risky!

Randy p · #**333** 23-08-2009

Ok, try 10 on the motor, 15 on timing boost. Set turbo at .5 delay and full. You MAY have to drop a pinion or two on this setup but run it first and check it 3 minutes into the run for temps.

BagofSkill · #**334** 23-08-2009

Randy, What can I expect the 10 degrees on the motor do? Is that more punch at low-medium speed, before the boost timing ramps in?

I ran alot of tests today and it seemed if I went too big on pinion I started to loose punch again. Favorite combo was 5.8FDR, Boost 24, Turbo 10.

Next week I can try adjusting motor timing and Turbo level.

Hi Chris,
I was running:
24/89 (6.68 FDR)
Boost 25
Turbo 15
0 Deg on motor (GM 13.5)

<45 degC after 6

I though I had you on the straight and wasn't lacking on the tight bits either. I'm pretty happy with it. The Turbo did start to cut in on the straight, it just kept pulling all the way to the end.

I did try a REALLY low FDR (8.01), with boost and Turbo max'd and parts of the infield needed the turbo to kick in, which it never did, so thats not the way to do it!!

Kristian was running his Novak at <5 FDR and could keep up but he nearly melted it in the last final!

What cars were these?

Randy p · #**337** 24-08-2009

10 on the motor will give the car low end snap. It also carries this timing throughout the run so you must reduce timing boost to use it like this.

Where do I start in a 4wd buggy on a short track (20m straight) with a Losi 6.5 with the new v200 softwere?

DCM · #**339** 03-09-2009

Dual Mode
Timing - 80
Limiter - 80
TP - 3
DB - 0 to 10 (depends how you like it)
BS - 100
NW - 8

Start about 10.5:1 gearing, check temps after.

Cool as I'm changing my 7.5 Losi to a 6.5 Speed Passion
