silvalis - its hard to say, without knowing some of the other settings on the esc and radio. Don't know why it would make a squealing noise on one profile compared to the other. I would understand if boost was enabled in one profile over the other- as far as overall power (making the tires balloon up), but from the factory profiles 1 and 2 should be without boost.

If you are not adjusting anything with a ProGauge then the factory settings from #2 should be more slightly more suited for an 11.5 (we don't sell that wind so its hard to say for sure). Everything in RC is trial and error. A set up that works for one driver my not for another. A little while ago I ran my 2wd buggy and thought I needed more bottom end power. I let a team driver try it and he said the bottom end was crazy aggressive.

What gains should I see with your VST tune up rotor 12.80mm TORQUE type in a 13.5T VST motor?

I am thinking of ordering one for the 13.5 in my Buggy today..

The 12.80 rotor is mostly used in Modified motors 7.5 and below. 13.5 motors already have enough torque and adding more will just make more heat and you will lose top end RPM. I would suggest using the 12.5 default rotor from our testing.

Congrats to all at the cactus.
I do have a few questions for whom can answer them:

1. How do i tell if i have the newest version/firmware for the progauge?

2. Where would i find some team driver setups? Just want to get a starting point for most of the categorys.

3. Whats the difference between the vtx1 and vtx10 speedos and which do we recommend for offroad?

4. I ran into a problem at the track. I have only ran the speedo/motor in blinky so far and i changed to profile 4 and made some adjustments but after about 1o mintues the throttle stopped. I thought the truck lost a pinion or blew the diff but both were ok. I checked motor temp, its around 140, so im not sure why it stopped. I shut off the speedo and turned it back on and it worked but the throttle was a little delayed. Could this be a sensor wire or is there a voltage cutoff for the battery? Any thoughts would be great.

Thanks,

ok, thanks.
The system I had in question with the squealing was a vtx10 and a SPv3 8.5 in a dex210/ko eurus fhss. Everything else on the ESC was default - apart from tx calibration. Might change to a 13.5 and boosted profile anyway...

Here are some answers -
1. The ProGauge does not have a software, it only reads what is on the speed control.

2. There are some posted on the Viper website forum. I have reached out for setups from Cactus and will post them when I get them.

3. VTX1 is designed for 1s use, mostly on road. It can also be used with 2s. Down to like 7.5 motors. I think the only other difference is the SBEC setting is lower because it's designed to work with 1s batteries.

4. First thing to check would be the motor and esc temp cut off, they are different depending in different on profile (unless you change it). Anytime there is a motor problem, check the sensor wire. It's an important and vulnerable part of the brushless equation.

silvalis- I had a SP motor previously that made a lot of noise, I know other who have as well. That makes some sense now.

I hope everyone has a great racing weekend!!!!

Viper on TOP and sweeps stock spec buggy classes!!!!

Mike Friery Arsenal used to dominate

The Cactus Classic was held once again at the legendary Scottsdale R/C Speedway while under new ownership from Hobbytown USA. This event would be one of the largest yet to show that this is not just one of the longest running races in its 26th year, but also one of the most prestigious and popular. The SRS/Hobbytown group put on a great event as usual.



In the 17.5 Stock 2wd Buggy class, it was Viper team driver Mike Friery taking the TQ honors after qualifying was all said and done. In the 10 minute A-main, Mike would get out to a comfortable lead and never look back. He used a VTX1 ESC with a VST 17.5 motor. Viper driver Nathan Lavery would also make the A-main event and finish a very strong 4th place.



In the 13.5 Super Stock 2wd Buggy class, is was Mike Friery once again capturing the TQ with Viper teammate Bryan Eady qualifying 3rd. In the 10 minute A-main, Mike would lead the field for the first few laps. However, a few mistakes would drop Mike back to 5th early on. However, with lots of determination, Mike was able to reel in the leaders and take the lead for good with a few minutes to go. Bryan Eady had a great drive as well to end up 3rd overall, giving the only two Viper drivers in the main two podium positions. Mike used the soon to be released Viper VST-BE 13.5 motor and VTX1 ESC for the winning combination.



Other notables include newly signed Viper driver Travis Amezcua and Billy Fischer making some of the modified A-mains. In the 4wd Modified Buggy class, Travis would qualify and finish 5th, and Billy qualified 7th and finished 8th. In 2wd buggy, both drivers again made the show with Travis qualifying 9th and finishing 6th while Billy qualified 8th and finished 9th. In the 4wd Modified Short Course class, it was Travis qualifying and finishing 7th.



Great job to all of the Viper drivers!

CONGRATS TO ALL OF OUR DRIVERS, WONDERFUL PERFORMANCE AND TEAMWORK!!!!

Hey all, i have a few questions please now that i finally got the esc plugged up and calibrated. i have the 10r. sorry if its a lot of questions at once. but they are on my mind and want to get them out while im thinking of it tonight.

1. i have to race 13.5 blinky mode. im in mode 1 of the pre load profiles. im using a radiopost tx and with nothing adjusted yet. i need brake on the brake throw. the drag brake is fine but i have no stopping power when i push my finger forward past the neutral it just rolls. can i adjust the mode 1 for more brakes and still have blinky?

2. i need to hunt for an esc for my ft 4x4 that i get to open monday for my b day. im looking at this 10r that i have and i see in mode 2 that it says 6.5 t to 9.5 t. what happens if i get a 550 5.5 motor?

3. what is hole shot that i see in table 8.2 and will that work with blinky

4. if i get the 10r for the 4x4 where do i solder that capacitor pack on at?

5. in the post above. 13.5 black edition?? when and where?

thanks all
sorry for so many questions at once

1. factory default on the brakes is only 75%-80% - you can turn it up to 100%, then adjust EPA to make sure the wheels don't lock.

2. yes you can run a 550 motor with the 10R

3. its just that - designed to try and help give you a hole shot off the line a the start of a race. Little more instant power to beat others off the line. and yes with blinky.

4. If you wanted to get the extra cap bank - it would solder on to pos and net battery posts.

5. Little something we are working on...... working pretty good so far!! But remember the VST has taken some recent checkered flags as well.

thanks for the reply. think i got my brake to where i want it while out testing on the street. i was able to adjust some items in the pro gauge to where im just shy of locking up from going full speed to stop. takes about 3-4 feet to get to a dead stop from full bore at a 50 or so foot straight shot. and blinky light is still flashing incase the blinky police show up at the track.

regarding question 2 about the 550 motor. so the wind is irrelevant? i have/had the question due to the preset charts that came with the 10r showing 6.5 minimum. is that a "suggested wind"? its probably more curiosity then application use for me. i assume when i get the vst 5.0L i wont be needing boost on it due to me seeing a post earlier in the thread by either nikos or ekim (i think, i cant remember who ) about using it in a sc10 4x4 with 62/14 that the punch was dropped to 35 percent.

edit. after posting this i went back to the pages and it was nikos. would you mind sharing what your settings are for this 5.0 L so i can get it on a sheet for my notebook?

I just received my 5150 Copperhead and have a question about setting it up with my TX. I have a DX3S, should my travel be set at the max 150% or 100%? I have both set at 150% and it seems to be working ok but with a 13t on my SCTE profile #5 it doesnt seem(seat of the pants) as fast as my NEXX10 with my Novak GTB/4.5HV with a 14t pinion(both running Nano-Tech 5300 65C). I was expecting the 5150 to be insane and it seems fast just not what I would expect a 4pole 550 5150kv. Granted this is just in my driveway it may be much different on the track, I'll find out tomorrow.
