1S Stryfe Build

So after purchasing some 1S motors from eBay a while ago, I decided to finally do something with them. I purchased a 1S LiPo from Components shop. It is a 1000mah 35C 3.7V. It came with a JST connector fitted, but I decided to replace this with an XT30.

The point of this post is to really demonstrate the power that I have found to be in these motors. The motors in question are FF130-3733 (10 01 25). They are of the same dimensions as the MTB 130 line only with a slightly shorter shaft. The wiring for this Stryfe is the standard simple loom, from the battery to a switch (Cherry DC2), then from the switch to the motors, then from the motors back to the battery.

The performance I am getting with this setup really surprised me. Gen 3 Koosh are getting ranges equivalent to my more high level blasters. The rev up speed is similar to Honey Badgers. I expected the system to be a bit lacking in the tourque department but I realised this wasn't the case. I can very easily 'finger bang' this and have it reach acceptable ranges and velocities. These motors are also incredibly quiet, at full speed they sound like a rhino running on a 2S.

Overall, I was just very surprised with this setup. I wasn't expecting the results that I got. I would consider this a very easy build for a first time LiPo user as it only uses 18awg wire and a smaller connector when compared to it's bigger brother.

The pictures show the size of the LiPo and how much extra room there is for anything you may want.

Cool.

Have you got a link to the motors and lipo?

Nicely executed modification, you've set yourself up for some future upgrades nicely. You can upgrade that micro-switch when the time comes.

Question for the floor given I'm currently elbow deep in motor spec sheets and stuff: FF equates to metal brushes, right?

is there a uk link for the motors?

Do you have any spares that you could open up? I'm curious to get at the brushes and windings in the absence of a spec sheet.

UK Link, sorry I don't know why I had the US eBay open - http://m.ebay.co.uk/itm/5x-130-mo...a8eb9cb6f1fff9e542%257Ciid%253A18

EDIT:

Boff, yeah I have one that I was just using for experimental purposes. I'll crack it open and put it on the Imgur album.

It should, which worries me. They're more than likely not genuine Mabuchi so they may not follow Mabuchi naming convention though. NewsonNerf, was the that FF130-3733 brush/size/wind code printed on the motor can (no mention/images of it on the eBay page)? Nevermind, it was in the imgur album. Razz

If they do have decent torque they could well be demanding quite a bit more current than Rhinos or Honey Badgers so you might want to consider a higher output pack and XT60 connector in the future.

SSGT, yes it was printed on the Motor can. Might have to set up a multimeter and see the draw on these?

So they are, I missed the imgur album link in your first post. Razz

The brushes look like carbon based brushes to me which is a good sign. Measuring current can be tricky. If you're not careful, and if you don't know the resistance of the shunt resistor that the multimeter uses for current measurements (it measures current by measuring the voltage drop across that known resistance), you may find that using the multimeter to measure the current changes the amount of current the motor draws in the first place.
