Venom Fireballs

[Allanto]

Hi iv been reccomended venom fireball motors for my off road double blaze twin motor. I want higher speed than my stock 540 27 turn silver cans, but i still want better off road performance (i..e. more Torque) is this true with venom fireball motors, I want better off road and better top speed.

If so what Turns should i get i.e. 17 turn 19 turn ect ect, bare in mind im using a silver star ultra esc and people have said they burn out on dual motor 19 turns.

 

Many Thanks and other cheep motor reccomendation appreciated.

I've got two 17 turn Venom's in my TXT-1. They make a huge difference to the speed and torque and are very cheap. Whats not so cheap is the ESC set up you will need for running them. You will either need and top of the range single ESC capable of handling the two motors or do what I did and Y lead two seperate ESC's together. You need to watch your battery as its quite a punnishing set up for it. Although the Double Balze may go slightly easier on things than the massive wheels of the TXT.

when you say watch the batteries do you mean they run out wuick because that not a problem, i have 3x 3700 mah 7.2v nimh batteries plus a charger whitch will charge all 3 in 6 hours, or do you mean the poor old tamiya conector will melt. if so what should i change the conector too? and how do i do it?

Havent you just answered your own question???? if using a silverstar ultra esc I wouldnt recommend anything more than the silver cans! 

I run 19 turn venoms in my twin detonator and they give great torque and speed but I have burnt out about 3 ultra star ESC's before I found out that what Modelsport say about the ultrastar is incorrect.  I got my information from the guy who makes the esc.

Your batteries will run out faster than you're used to if you're using two 17 or 19 turn motors (stating the obvious really). But also having two high powered motors coming off one battery does place greater strain on the battery than any usual set up. If you've got cheap 3700mah batteries, as I did, they can easily overheat and melt, as mine did. Though as i said earlier the Double Blaze may be a slightly different kettle of fish from the TXT which is obviously a lot bigger.

ive been running twin venom fireball motors for a long time now both in my clod when i had it and in my twin detonator i use the 19 turn motors in these and it produces loads of torque and speed

you dont need to buy a top of the range esc for them either, i use the ripmax xtra no limit esc (used them in the clod and wild dagger with these motors) and now ive got the same set up in my twin detonator this esc is fine with two 19 turn venoms just make 2 Y- leads for the motors and it runs them fine (over 2 yrs so far and no problems)

the only other thing i would recomend is uprateing the conectors to the deans type not that ive had any problems with the std conectors

just for refrence i also run cheap 3700mah battery packs with this set up

Okay quick question about Venom Fireballs themselves.  On their website they list these specs for their motors:

Fireballâ„¢ Modifieds come in four different winds to suit your need

for speed.

• VEN-1312 [15 turn Double]
  • 7.2 Volts / 29280rpm 8.4Volts / 34920rpm
    

  [*]VEN-1313 [17 turn Double]

  • 7.2Volts / 25560rpm 8.4Volts / 30180rpm
    

  [*]VEN-1314 [19 turn Double]

  • 7.2Volts / 18720rpm 8.4Volts / 20500rpm
    

  [*]VEN-1315 [21 turn Double]

  • 7.2Volts / 15660rpm 8.4Volts / 18360rpm
    

But, then I went to trinity's website to look at the specs for the P2k motor and found..

TYPICAL SPECS:

RPM: 30,600-this is an optimal manufacturing figure, actual RPM will probably be lower and vary between samples.

Power: 116.7W

Efficiency: 70.7%

Torque: 175N-mm (Newton-mm)

Okay, so what gives? I know that the spec's for the P2k are "optimal" AND that the timing for the P2k is set for 24degrees advanced while the Venom's are set for Zero degrees. BUT, shouldn't the RPM's be higher for the Venom Fireball motors? Or are the P2k's really a whole lot slower?

...the timing for the P2k is set for 24degrees advanced while the

Venom's are set for Zero degrees. BUT, shouldn't the RPM's be higher

for the Venom Fireball motors? Or are the P2k's really a whole lot

slower?

Bear in mind that the Venom motors do have ajustable timing, which, if ajusted, would result in more rpm.

Bear in mind that the Venom motors do have adjustable timing, which, if ajusted, would result in more rpm.

yeah... but comparing the 27t P2k @ 30k+ RPMs vs. the 21t Venom at 15k+ RPMs it just seems like such a HUGE difference. Could it really just be because of timing?

Also consider that the P2k is the type of motor you use when you want

to win ROAR-sanctioned stock races; whereas the Fireball is the type of

motor a backyard basher on an extreme budget uses.

that makes sense...

The Trinity stock motor is designed for performance, so it uses quality

parts with fine tolerances, is fitted with the best brushes and springs for the motor and the

armature is carefully balanced by hand, all designed to get the absolute most

speed out of it.

The Fireballs are built down to a price. The brush hoods are just

screwed on instead of being properly aligned with the armature, the

armature isn't properly balanced and the components are the cheapest,

not the best. They come with the timing set to zero as that is cheaper

than finding the optimal timing on each and every motor.

At least they are better than the extremely cheap Orion Pilot motors,

those have so much of a gap around the brushes in the holders that the

timing could adjust itself, usually shortly before the motor fell apart.

You would also get a lot more speed out of a Fireball if you set it

with the 24 degrees advance a stock motor has, it wouldn't last too

long before burning out though.

[jimbo858]

well with that explanation the $27.99(US) for the Trinity motor sounds like a good bargain! 

I just burned up one of my 21t Venom Fireballs in my LunchBox.  I think I'll go to the LHS one of these days and pickup a Trinity P2k. 

Anyone have any other suggestions?

Thanks for that explanation; I've been trying to figure out how Venom

can sell a motor with dual ball bearings and ajustable timing for $15,

it seems too good to be true.

okay wait.... before I trash the old fireball... how do I know when I've "burned" the motor?
