Pulled the trigger on a vtx10be for my T4.2 the other day, can't wait to run it. Gonna run 17.5 indoor for a little while till outdoor starts, then the 8.5 goes in. My truck is all Viper power now so It will be interesting to see how the vst motors act with the vtx10be, I think this Castle esc I'm running doesn't do the vst motors justice.

I have the VTX10 /VST 9.5T combo in my SC10.2 truck. I have the gearing at 20 pinion, 84 spur gear as a start. I do not want to melt anything. Is that a good start or would the 20 pinion and 75 spur gear be better?

Your right on target I run 84/22 med size track 35 deg on can 9600 pwn and 95 on the punch truck pulls like a banshee!

Hi Nikos, I have a VTX10R BE esc and a VST2.5T motor. I set up my esc on program 6 (modified blinky), my motor on default mechanical timing and I run them in a 1/10 touring car on a large outdoor onroad track. My car is silly fast for a couple of laps and then performance drops suddenly, to like 80% for the rest of the heat. The esc gets really warm - no thermal shut down, but I guess this is normal due to the super powerful motor. What do you think causes the drop in performance? Could it be my batteries? They are old I'm afraid and maybe they can't handle the power requirements. Any other ideas? If I reduce the mechanical timing to 15 degrees, will it help? Thanks for your great products and your support!

I have it in practice mode right now. I get to run it the first time this Friday.

Can you change the punch and timing in training mode? I drive so bad I need reverse :)

Buzz.

punch yes, timing now. Timing is locked out when reverse is activated.

anyone using a vtx10 non "R" without a fan in a b44.2 with an 8.5 motor. No boost.

billtc3 - its most likely a combination of the motor and the batteries. As you mentioned the 2.5 is crazy fast, but crazy inefficient as well. My guess would be that most the people you are racing against are using motors in the 4.5 range - still crazy fast, more efficient over whole run. Decreasing timing would help slightly, but don't know if its enough. And yes, when pulling that much with a low turn motor, condition of batteries makes a difference. What you describe is a trait of older batteries.

Wildcat - If you have some cooling holes cut in your body to be sure air is getting through, you should be in good shape. I ran a 7.5 in my 4wd and a VTX10 in development a few years ago -- unfortunately I haven't run much 4wd buggy since.

Niko,
I am hearing that all new vtx10's will have the same caps as the BE version. Is that true? I hate trying to find chassis space for caps. The little caps mounted on top were pimp.

:rolleyes: Look back at the second post and Niko2002 posted photos of the VTX with the pigtail caps mounted on the side. Personally still not a great option for the B5, don't think it will fit like that.

hmm, the low profile caps can sure be mounted, but removing the cap pcb from the terminals is nothing short of hell, lol. I will pass on that. shortening the leads "should" make the caps more efficient, but again, they are huge.... oh well

Yea if you have a hot enough iron you can get them off but I'm concerned about damaging the ESC.

I just setup my temp sensor. What is a good temp for this motor? What is a danger temp? I have a couple more temp sensors on order. I want to add one to the ESC.


Buzz.

160 on the motor same for the esc imo

Thanks. I really do hate letting the magic smoke out of my electronics. You can never seem to get all of the smoke back in to make it work again.
