Thoughts on this.

How about this, http://store.polkshobby.com/scripts/...0100&conum=002
and a Losi Insane? You would be into it for around $35 (esc and motor) plus shipping.

Hey bugman

I would be willing to make that plate for you, in South Africa unfortunately and think postage would kill it before it started...

Very interested in doing the Mamba Micro and outrunner idea, any help and ideas would be great.

As for the ESC, I was given a 1/16 Revo a while back that was originally brushed. The previous owner had decided to try and save money by buying the cheaper model and fitting the brushless stuff himself. It was an Easyrun 25A esc and 7800kv motor. It handled the revo just fine, not blindingly fast and the motor would heat up fairly quick. That said i am sure the 25-35A esc's availiable at those HK online shops will be fine in an MRC

I wish I could see that site at work.

I should hopefully have a plate this afternoon.

[toyotatrucks83]

I'm running a hobbywing 18A ESC with a 3600kv tacon 2040 in a MRC pro. It works great for a basher. I'm also running a 25A hobbywing with a 2900kv Tacon 2445 in a maxstone16. The MRC pro is very limited on space for mounting. The 18A esc is very small and has held up to months of abuse. 2s and 3s lipos. No extra external BEC. I've been super surprised. I agree with getting a program card. It is so handy.

[redemon]

But how does it work on low speed?

[redemon]

So which one 18amp or 25amp?
Does it depend on what motor you use?

[bugman72]

If there isn't much difference in price (or size), then I would go with the higher rated ESC.

I almost got the Tacon inrunner, but like the power curve of the outrunners more. Plus, outrunners have a higher efficiency than inrunners.

So, redemon...PM me about the plate. I'd like to get my hands on one.

[redemon]

I will post up some pics as soon as its in my hands.

Im prolly going to get the hobbywing esc and the 14 dollar inrunner that bugman is using

[toyotatrucks83]

Both the hobbywing esc are just brushless sensorless motors only. The low end is fine I guess. That seems to be more dependent on the motor you buy. I was running a 2040 4120kv and it was pretty fast. But I couldn't get it to run slow. I'm able to go pretty slow with the 2040 3600kv without cogging. But these setups are in no way comp level. They won't go slow enough to creep in tricky situations. I've managed to get up down and around some pretty narly stuff but it takes alot of practice with throttle blipping and technique.
The 18A esc is much smaller than the 25A. I can post some pictures of the 2 ESCs so you can make your own call. Even with the price being roughly the same if I needed to buy another esc to run a motor in the size range we are running I'd buy the 18A hands down.

[toyotatrucks83]

One more side note. I don't know if this applies to all brushless sensorless ESCs. No matter what kv rated motor I have, a 2s lipo always allows smoother and slower slow speed than 3s. I tried a few different batteries of different sizes and rating to see if it was a problem with battery input and esc programming.
I make this note cause I was attempting to run a really low kv motor and just use 3s lipos to gain wheel speed back. But it didn't really work that way. My 4120kv did better slow on 2s than my 2900kv on 3s. The 2900 did way better on 2s than the 4120 on 2s. But that should be suspected.

[bugman72]

But you are discussing the attributes of a brushless inrunner. My outrunner is rated at 3500kv and I am using an 800mah 40C 2s lipo. I can very much creep with this combo with no issues of cogging. I would also disagree with my particular setup not being comp-worthy. I'm not taking any offense to your statement, I'm making a statement about the use of an outrunner and the advantages out holds over a non-sensored inrunner. Do a search for the outrunners that JohnRob has sold over the years and the number of National winners that have used his motors in their winning rigs.

Now, while I am not currently doing this, JRH's philosophy is "volt up, gear down". I don't think you would necessarily be doing yourself a disservice by running a 3S pack, as long as you gear accordingly.

My opinion...if you have the extra little bit, go with the Sidewinder Micro. It works with both brushed and brushless motors, is super small and can be programmed with a Castle Link to tune however you like. If you don't feel like you have quite enough control of the speed on the low end, go in and change the throttle curve to take out some of the linearity at early trigger pull. The Hobbywing ESCs just don't offer that much customization. I know my 35A Hobbywing ESC and program card don't and that's what I'm running in my 2.2 torsion with a Revolver Black.

[toyotatrucks83]

You are very right bugman. I am only talking about inrunner motors because that is what I have. Just sharing my experience. I would like to try an outrunner.

[redemon]

Tacon has realeased a finned 2900kv motor.
Im gonna try it, and get the motor that bugman is talking about.
Im gonna try different things.
It wont be hard to sell what I wind up not using.

[bugman72]

I believe that there are a few guys on RCC that are running the finned 2900KV motor. From what I remember, you will need to do some trimming of the fins in one area to get the motor to fit. I would be very interested to hear your results after comparing the two motors.

[redemon]

Yeah I will have to trim some of the fins where it sits at the transmission.
But the front and rear bearing is sealed on the finned ones.

[redemon]

I will hopefully be ordering all my stuff tomm or saturday.

[bugman72]

Any luck on the motor plate, redemon? Just curious...don't mean to rush. Oh, and Toyotatrucks83 just let me know that the outrunner at HobbyPartz is currently out of stock. It might be worth a call or email to them to find out when they anticipate the motors coming back into stock. Sure wish they had email notification like HobbyKing does.

***EDIT***

I'm not sure if this motor will work, but it's pretty close to mine.

http://www.hobbyking.com/hobbyking/s...er_5250kv.html

It's a 5250KV outrunner that is only 2mm larger in diameter than mine, so it should fit on the transmission. Probably the biggest benefit is that it has a 3mm pinion shaft, so standard pinions should fit. Plus, it's in stock. I'd be interested in hearing from someone as to the performance of this.

[redemon]

I sent you an email bugman.
He told me he cant get the file to open, it said it was creted by an incompatible version. Whatever that means.

[bugman72]

Sorry, didn't realize that was YOU. I had a couple of other friends checking on getting the part machined as well. Replied to your email this morning with 2 new files. Did you get it?
