How about a bit more separation between the solder points for the wires.

+1 .

wouldn't mind the ESC not coming soldered either versus the superman strength stuff used now :lol:

Sorry...I don't know if this had been posted before. I just got a VTX8 with A62 on my SCT410 (running Tekin Pro4 HD 4300kV), I wanna know if it is necessary to update the firmware to A64?

What is the difference between firmware A62 and A64?

There is no A62, do you mean A61?

Anyways definitely upgrade to A64. Here are the upgrades.

Thanks for all the suggestions guys..... all I can say at this point, is we do have our own items we are looking at. Don't think much needs to be changed... but its been 5 years, time for a something a little different.

For some notes....
- unit coming with wires not soldered = we did that originally, almost 1/2 of our warranty failures were related to poor soldering or crossed connections. Yes, the industrial solder was a little tough... but it would not fail.

- separation between solder points = would be great, but hard to do unless you make the speed control larger -- no one wants that.

- data logging = if it can be done to get actual useful data.

- truggy motor = what is a truggy motor? I have seen and heard of a good number of driver who have successfully used our motors in truggies. If you like we can put them in a different package and call them truggy. The 2700 was only done in limited quantities for those "crazies" who think more is better.

i am one of those who use your motors in truggies and they work well, however, from what I am hearing there are still benefits to a truggy sized motor like what Tekin sells versus what you currently have avaialble. I'll find out this year as I plan to try it.

I guess I will clarify this slightly. When I say what is a Truggy motor?

When we were developing our VF8 motors we asked our drivers who ran truggy what they needed, sent them motors to test. The results we got from them was 1900 motor was more than enough for what they needed. It didn't require something completely different or redesigned to provide a high level of performance.

yeah, I am curious on that myself. as you know I felt the VF8 series worked well in my truggy, but this year I do want to compare what kind of performance difference I gain or give up with a buggy sized motor versus a truggy sized motor, as far as can length goes.

I am expecting that if traction is there, the truggy sized motor will outperform the buggy sized motor torque wise. Also will run cooler.

But its relative to conditions you see. So if I see say 160 on the buggy sized motor but 130 on the truggy, but performance is equal, does it matter at that point?

hope tha tmakes sense.

For the truggy vs buggy motor, I run a .21 nitro engine in my truggy. same as gets run in a buggy.

I can't imagine needing more motor than a 1900 as I had to turn punch down in buggy. Tekno recommends a "buggy" motor for their et48. If people really want more bottom end I guess just go up in KV and down in gearing.

so i had a viper vtx10 B.E on amain on my wish list and i was about to get it today and now its gone... wth :confused: discontinued ? i needed that too:(

I haven't heard or seen very many locals let alone pro's that run the shorter can Buggy motors in electric truggy.

Think of the Truggy motor as a tuning option, like a 540 vs a 550. The heavier SCT Trucks had trouble with temps with the 540 cans. The 550s run cooler, have more torque, and allow for more aggressive gearing.

Running a Buggy motor in a Truggy will work, but your really stretching the limits of the motor. I could see it working in lightweight truggies on smaller tracks, but most truggys are heavy and are run on large tracks. The extra torque is needed in these situations. You have to be spot on accurate with gearing using a buggy can in a truggy. You generate less heat with a longer can (truggy motor) so sometimes it could be an issue to run a buggy motor on a truggy.


There are many manufacturers that have made truggy motors, Tekin, Hobbywing, Orion, Trinity, Castle etc. Honestly, I am surprised that Viper would take a "What is a Truggy Motor" mindset.

Does anyone know what rotor comes in the 10.5 black edition spec motor, part number VIPER10501?

12.3 spec rotor. BE10 Mid Torque 12.5 or BE11 High Torque 12.5 rotors would be options if looking for a little more zing...

We spent the better part of year testing motors and configurations. None of our drivers ever reported any issues in speed, temperature or overall competitiveness using the VF8 motors in Truggy.

There are different ways to build a mouse trap. Yes 540 2 pole motors to 550 2 pole motors made a huge difference in 4wd SC - then 4 pole, beat'em both. But we made a 540 4 pole, that was more efficient than others 550 4 pole.

There are many different factors that can generate heat in a motor including, stator design, wire size, rotor design, stack spacing, internal can design, sensor --- and we are not even talking esc or software yet. There are always options to work with and try...
