I have decided to add some power to this, and have a 120 amp esc on the way, and am installing a Tekin 5 turn gen 2 in it. I had the motor but not enough esc to use it as it takes a lot of power to use. I need help on the pinion, I have a 20 in it now, but feel I need to drop down some on it, what size for an indoor track, small, clay?

I took the old Savox 1258TG servo out of this awhile back as it was acting up, as the buggy was driving erratic, all over the place. I forgot about removing it until I tried installing it in my DEST210. It would lock up on left turns for some reason, needless to say, I won't be using this servo. This would explain all my steering troubles in the past with the DEX410, that caused me to put it away for awhile. I recently put a 1257 Savox in it, and it steers great now. I hope to take better care of this servo.

I know this is somewhat frowned upon, but I am selling a bunch of upgrade parts from my sons 410 roller. It would be a great chance to upgrade your car, or add to your spares..search my posts and pm me if you find something..

Sounds like the HV 1258TG is using up more current. This is normally an indication that the BEC in your ESC is getting weak and can't supply enough amps to the servo to operate. The 1257 is a 6v servo and will use less power compared to the HV savox. Normally installing a power cap on the receiver should help when using the 1258 servo.

Im having my first race with the v4 this weekend, Dino your setup is working well only thing I did was use 1.3mm rollbar in the rear as it was loose with the 1.5, im finding the 7.5 is not enough unless im at full throttle for the turbo to kick in which is fine on the straight but the back straight is bumpy and the turbo unsettles the car would boost help here or be worse for traction, what about endbell timing? Im using hw 930 mod software geared 87/21 sp7.5 the 930 stock software has more adjustment would that work better, just curious how most guys setup there speedys any suggestions are appreciated thanks

Do you have the under the chassis rear weight? The extra weight in the rear helps keep the back end planted. As for the roll bar, its personal preference on the track. High speed or flowing tracks like the 1.5 to keep the back end from rolling to much, tight tracks, 1.3 - unless you need more steering on a tight track the 1.5 will help it rotate more.

As for gearing. I think you are a bit under geared. I normally run a 21 or 22 with a 6.5. With a 7.5 you should be at at least 22 or 23. I have even run a 24 with a 7.5 before on a big track. It was more manageable on power.

Just a question, if you are having trouble putting the power down it your track cold temp wise. Perhaps dropping 1 wt down in oil may help. It may help on the bumps. Maybe a video of your track and car can help me fine tune it more for you.

As for the HW software. What are your adjustments?
Remember the max total timing is 85 degrees. (Endbell timing + software)

Boost - I normally don't run this unless you are running stock. It tends to give you more low and mid corner acceleration, but I don't find it very linear or smooth. Especially not for offroad. The only time i would run boost is when I have a technical track and a very short ramp in a section that I need to clear. Most of the time on-road guys use boost since they have the grip to utilize this.

Turbo - This is mainly the top end setting. I normally run like 10-15 degrees of turbo timing. Remember this timing ramps up with rpm. I don't like running a very high turbo or boost setting, again, it unsettles the car more. I don't need to feel the turbo, I just need it to go a little faster down the straight. LOL.

You are better off changing the Punch 1 settings higher if you need more grunt. Punch 2 is mid to top end power. Think of Punch 1 like traction control. It works from 0-50% throttle. On 2WD I set it lower to control wheel spin (around 5 to 10), allowing me to run the slipper slightly tighter so that if I punched the throttle above 50% (punch 2 settings at 10-20) I can clear jumps easily, but let the software control the bottom end wheel spin. Makes sense? I can make a 6.5 feel like an 8.5 out of an corner yet it has the mid top like an 6.5. It really depends on your punch settings.

Low bite, I do Punch 1 at 10, Punch 2 at 20. High bite, Punch 1 at 15-20, Punch 2 at 25.

Endbell you can always add 10-20 degrees of timing for more power - I don't normally use more than that otherwise it creates unnecessary heat.

I used to run the HW ESC and love them.
Our entire team in Canada now use the Toro TS-120. It's almost the same ESC and has the same software settings, but it has blue tooth settings so I can change the setting on my cell phone or ipad or tablet.

The Orion is also very similar in programming.

Thanks Dino I do have the rear weight but I only have shorty lipos so that would be lighter than your saddle pack setup , temp outside is 26 but will be 30°c sunday, as far as punch I have it at 3 its a xerun v2.1so it doesn't have the different punch settings like the v3, I have turbo at 16 but I will try 10deg endbell timing 22t pinion and turbo at 10 and see how that goes

The servo acts like it is something major, I need to take it apart and see what's wrong. I just got a HK 120 amp turbo esc to try out. This thing looks solid and not a bad size at all.

Dino_D

With shorties, the back end is much lighter, so you need to compensate with lighter shock oil as you don't have as much weight in the back. Also you can try using the side weights or put some lead weights along each side of the shorty to bring up the rear weight a bit so that your back end feels more settled.

Ok will try that but seeing as tomorrow is going to be hot the rear wt might be ok, and I was way off with gearing I am now 87/24

My Track Star esc didn't last long. I smoked it in less than 5 minutes. All I can think of is it must have come in the nimh setting. Oh well, forget the 5 turn motor for now.

Dino_D

Maybe gearing - or boost or turbo settings are too high on the esc?

It never hit the floor. I think that nimh battery setting is the default setting and the lipos smoked it. Yesterday was one of "those" days, that is better served hiding under the bed until the day is over.
