Nitro TC3 conversion coming......
 

Not being satisfied with my 18T for speed running, I decided to get an onroad car that is 1/10th scale, and also Nitro, so I have more room to do a conversion over a typical electric touring car.

I just won a NTC3 on fee bay for a very cheap price, and I even get to sell off the nitro/radio gear to get back some more dough. Nice!

Anyway, looking around the net at specs, I'm trying to pick out my motor/esc. I read that for the world's fastest rc car challenge, a NTC3 was used (in brushless trim) for the same reason I chose it. His specs were the Phoenix HV-85 controller, and a Neu 1509 motor, with the lowest kv, I believe a 2Y, so 1820 kv rating. Also used an 8s Lipo pack, most likely to keep heat down from current draw, and for size reasons.

I was thinking of using a little higher k/v motor so I can use less battery (less weight), and figured that heat wouldn't be TOO much of an issue since the car is relatively light. I'm torn between using the 1509 or the 1512 series for more torque and maybe less heat since I'd be underworking it.

For my ESC duties, I haven't decided yet. I'd like to use a Quark just because I'm used to them and know how to mod them to keep them cool, but at the same time I would like to just once have a plug and play system that doesn't need me hacking into it.

Throw me some ideas, car should be here by the weekend then I can figure out a mounting idea.

I too,a monster truck/truggy person at heart,has been bitten by the onroad bug.My vehicle is the Traxxas Nitro 4-Tec,though not known for its handleing all I care about is.....topeed.My setup is the Mamba Max 5700.With 41t spur,15t pinion my best thus far is 52 mph on 2 cell lipo.I'm still waiting for my 3 cell pack to arrive.l

This would be nice, I just traded my nitro CRT.5 for a nice NTC3 and thought this would make a really good brushless touring car. The NTC3 is built so much better than the TC3 and TC4. If you come up with a motor mount please post pics or if you plan to sell one I'm in.

Have you made a motor mount for you'r NTC3 yet? If you did do you have pics? I am going to start working on mine soon, nowhere to run nitro around here and it would be cheaper for me to convert than buy a new TC for my local track.

Thanks.

Here you go....
 

Here's my mount. I actually felt inspired today (thanks to your post), and banged it out in a couple hours of tinkering.

It's a piece of 1/8" aluminum angle stock, bought it from Lowe's a long time ago, 2 inches x 2 inches.

I just drilled a big hole in the center-ish, then took a motor mount from an E-Maxx, and drilled ONE hole at 6:00, and then at the 12:00 spot, I made a groove, to allow for adjustability of the motor, for pinion sizes. I clamped the e-maxx plate down and used my Dremel with 1/8" bit, and tried to not wreck the E-maxx plate too much. It ended up plenty good for what I needed, just isn't AS pretty as some.

I was going to do Lexan and all like I did with my brushless MGT convo, but this is simple enough and strong.

Drilled some holes to line up with the stock engine mount holes, and have some extra back and forth play there if needed.

3mm bolts with locknuts, and boom, instant motor mount.

I want to shorten up my wires on my Mamba Max 4600, but am waiting until I get a battery, so I can figure out final layouts, move everything, then make them as short as possible.

I could never charge anyone for something like this, I sorta wing it. There's plenty of football on tv on Sunday afternoons, so I bounce back and forth, or measure it up in front of the tv, so it doesn't really count as "time" that way. riiiiight. I used a Dremel, a cordless drill, a 1/8" drill bit, a piece of sandpaper, a sharpee, a square for measuring, and a set of digital calipers for fine tuning. Oh, and a dry-erase board for drawing up ideas.

Just sit and have a look at it, no metal shop needed, really.

That looks good, I was thinking about trying to find some carbon fiber like that for the motor mount.

Carbon would rock, not sure how to make a 90 degree bend though for the mount, unless you are thinking of some other way to mount it down to the car.

There is probably something else to mount it to other than the bottom deck, then you could just use a piece of flat carbon sheet stock and go to town. That'd rock.

Was thinking aluminum servo mounts. I think I've seen carbon bent like that, not sure though.

any updates to if someone made a quality mount for the ntc3?

The easiest way to do it is to look at the mounts Tekno makes. They are generic based off of your motor can size, and then it's bolt and go. I'm using one now on my MGT 8.0 conversion, in another thread I have going. I'm still using my own from above, it's fine, but there are cleaner options.
