Smart Idea

Yes, should be.

Would a tekin 2050 be better in this buggy then the 1900?

It will have a bit more top end but the 1900kv is plenty. I have it in a VE8 and its just the right power, even for a big track that I run on. The EB48 is much lighter than a VE8 so I would probably go with the 1900kv.

I always been more of id rather have torque and be able to tear it up in the infield and on the quick jumps after turns like most builders like to do so ok ill go with the 1900 since I know the 1700 doesnt have the top speed and runs hotter if geared the same for speed

I would say use the various calculators out there and determine an estimate on the top speed you are seeing right now for your track with your current vehicle. You can then backtrack to see what kind of gearing you need.

To be honest, the 1900Kv I would think would be plenty too with the standard pinion setups. When you need a clutch bell however they are limited in size (at least, the biggest I have seen is around a 20T) so if you need to gear up, probably a motor with more Kv will keep you in a clutch bell size that is more readily available.

So the 2050 is better since I plan on possibly using the tekno clutch then because of the pinions. Better because I want to use the clutch then is what I meanThanks so much for the great info.

That is what I am leaning towards based off of the gearing I am seeing with my vehicle for tracks out here (Tekno V4 D8, 44T Spur, 19T pinion, 2050kv Tekno motor)

It would be cool if tekno would do more clutch bells themselves in larger sizes than the 18T.

Well looks like 2050 then so I can use the clutch and keep temps down and runtime up

I'm wanting to get into the 1/8 e-buggy or e-truggy game at the end of the summer (bonus time!) and the EB48 at the top of my list. Might as well start with the best right? Been doing the 4wd and 2wd 1/10 SC thing and while it's fun I want something with ultimate power and handling. 1/8th scale electronics are so dang expensive though I might have to "borrow" the RX8 out of my SCTE for the EB48 and run something cheaper as a replacement...

I can't wait to see the pictures and videos after they've started shipping!

some options for you on the electronics front:

- Speed passion GT2.0 Pro does 4x4 1/10 easily with no external BEC
- Speed Passion Silver arrow V2.0 ESC on sale right now for 1/8, like $70 shipped in USA new

Have heard brushlesshobbies 120Amp ESC can do 4x4 1/10 as well.

Pretty much what I am doing to save money is the speed passion stuff combined with Tekin motors.

The same thing will happen to the 1900kv if you gear it for the same top speed as a 2050kv. Gear it for it's best perfromance, don't worry about top-speed. There aren't that many tracks where top speed can be translated into a faster lap time.

The suggestion on top speed gearing is to give you a relative starting point in comparison to another vehicle or motor. The 1900Kv versus 2050 Kv based on the experience I had owning both didn't have issues with temps when geared for similar top speeds on 4S. As you drop Kv however, this appears to be more of a problem on other motors when maintaining the same voltage.

You will of course adjust this to the feel of the vehicle around the track, but as is often asked, this will give you a starting point.

Out here, I find that gearing my motor to top out towards the end of the longest straight works really well. (info I got from the late Big Jim). I then adjust it for feel around the rest of the track, which, usually works out to a pinion size or 2 at most. This is assuming you have a the proper motor for the given voltage you plan to use.

You mean by looking at laptimes or... ?

Best torque and performance within reasonable and safe temp. If you gear a lower kv motor to have the same top speed as a higher kv motor it will obviously run hotter but several times now I've read "the 1700kv runs hotter". It doesn't, it's just being run in an over-geared condition to attempt to get the same top-speed as a 1900-2000kv motor when it's not supposed to be as fast.

Accept a couple less mph. less top speed and enjoy the extra run time and controllable torque.

It will be interesting to see what the sweet spot power system will be with this new chassis. It'll be light enough to possibly open up some other, more mild options while yielding good performance. Anything we can do to strain the electronics less is a good thing for E-1/8.
