Tekin FXR and 4 cell Lipo

[SDS Customz]

I have ran my fxr's on 4s for quite some time(with some coating even fully submerged wot) with no issues. Get hgher volt caps and roll. I run 16 turn 5slots or 35 turns

Thanks dude..So what I shall'd do just need cc bec connect with battery and other end directly into RX?

And disconnect red wire coming from esc at the receiver. Don't forget to swap to higher voltage capacitors on your fxr's.

[ninja turtle]

so to the people running 4s on the fxr, what did you set the voltage cutoff to?

it should be around 13.2 right?

with the hotwire i can only get the setting to go to 12.

what am i missing?

thanks!!

[nitrooxide]

And then!!

pick it up, its itching everywere 4s sounds great

[nitrooxide]

bump again.
come on ppl , you guys were did you all go?

So how did it go etc etc.
how many 4s packs are you up to atm??

please let us know.

i ran dozens of packs before i gave up on 4s eating berg 3rd gears. but the fxrs held up without issue.

Sweet!

My Wraith is a blast on 3s 40C with Traxxas Titan 21T 550 motor, and 13/56 32 pitch gearing!!! I'm getting the itch to drop to 12/56 gearing and up to 4s 40C...not sure my driveshafts and gears will like it though.

EDIT" Yes I'm running external CC BEC.

Your titan motor is not going to like 4s. It will take it, but it will not last long. The brushes are not serviceable, and they will not last. But it will be fun while it does, and at $23 a pop, the motors are cheap enough.

[Natedog]

LOL, I was afraid of that but I'm really loving the torque and wheelspeed lol....makes me giggle uncontrollably... Yes, I knew about the brushes but they are harder compound than most serviceable types...any idea how long it would last? What motor would you recommend that will last and have powder like the Titan 21T?

[The Violator]

I would stick with the titan motor, just expect to replace it. How long it lasts really depends on the luck of the draw. Brood makes 550 motor and it is priced well, but I have not ran one, or even seen one run so I cannot speak to that motor itself ( no specs on the page, maybe EddieO will chime in). I can only speak to the incredible performance of Broods other products and, IMO, if he is willing to put his name on it, it must be a decent product.

Thanks, that looks like the old Kyosho Magnetic Mayhem motors that had forward and reverse rotation versions...great motors! Still got one used somewheres. Also similar were the Kyosho Lemans PT 360 and ST 360, one had bushings and the other had bearings...also great motors. Looking into the Brood 550 motor!

It's not the brushes on the Titan motors that are the problem in my experience with four of those motors. It's the brush springs bending and failing. They're bent tabs, and they get too bent and warped or snap apart and don't work anymore. And that was on 3S lipo.

[CREEPERBOB]

Does anyone know if CI still sells the larger caps, I could'nt find them on his site. I've got dual FXR Pro's and some 1250mah 4s lipo's for my super and need the bigger caps. TIA.

Thanks, they probably overheated the springy tabs that the brushes are attached to and lost their tension, then it arced more, got hotter and melted down?

That's new...and nice!

[CREEPERBOB]

Thanks guys , I noticed the Tekin 1000uf cap is still 16 volt where as the one from CI is 25 volt. The 4s are 14.8 volt, pretty close, maybe the 1800 uf would be a better choice at 25 volts.

Yes, better to have a little more capacitor than you need. When they get overheated they burn up and or pop. Just replaced a motherboard in computer last week with several burnt and puffed caps lol.

Yeah, we recommend the 1800uF for 4S. Have Fun!!
