Minicat Velocity Cat-New

[Phaleronic]

Hey fellas,

I just received my new Velocity Cat and I'm impressed. I do have one issue though and that is a penny sized area of spider cracks on the left side of the hull (i'm attaching pictures). EDIT-Jim and crew were responsive and offered to rectify the crack situation promptly, they really do help the customer as much as possible.

I have a few questions though. I have my old Futaba Magnum FP-T3PG that I'd like to use in the boat, but I need a new battery pack for the transmitter (can't find either on ebay)-and charger, and a new micro receiver. Also, what brand and rating of battery should I pick up for this thing?

Thanks for any help in advance! :)

see if this fits, I have this in the mini eco from minicatracing http://www.hobbypartz.com/77p-sl3000-3s1p-30c-3333.html

I am building one from a hull and hardware I think most people are using 3s 2200 mAh batteries

Great, thank you for the link, I'll give them a shot.

The directions give a maximum of 2200 mAh for the boat, what happens if I push a higher rated battery (motor burnout)?

[Rich]

A larger mAh rating will only give a longer run time. Think of mAh as the "gas tank" in your car. I would take some measurements to see if the lipo I suggested will fit.

I think it's more of a size restriction these boats are tight for space

These are designed to use 3s 20c-25c lipo, Any higher on c rating & you risk damaging the esc. sailr on this forum is the best one to speak to on any of the Minicat Racing boats. Or get in touch with them. Martin.

Got it, I'll take some measurements tomorrow.

Thanks for the feedback Alex.

I'm talking to Jim about the cracks, I'll ask him about the battery threshold too. Thanks Martin.

A higher C rating WILL NOT damage an esc! There is no way possibly for that to happen! If the boat is using battery C rating as a method to limit current draw there is something seriously wrong! The higher the C rating the more amperage the battery is CAPABLE of delivering, not what it's going to try to force into the esc and motor, current draw is determined by the motor and prop not the C rating!
The higher the C rating the longer your battery will last in terms of charge cycles as it isn't heating up as much or being stressed as much as it is not being discharged as close to its limit.

[sailr]

Sorry, but you are totally wrong! High C rating batteries deliver a very high PUNCH on first use which some FETS and Capacitors cannot withstand. This is from experience, not conjecture! We found this with our older ESC's which were designed back when 20C was the latest and greatest.. Our new ESC's should be able to take them OK but as a precautionary note we recommend staying away from anything more than 25C.

Why do you think people are adding more capacitors to their esc's? You never heard of this until 30-40C batts came on the scene!

You heard back from us immediately upon contacting us. Too bad you posted this before giving us a chance to make it right to you. You proposed a discount or replacement. You agreed to a certain amount of refund which we have provided to you. Your post makes it sound like we were not responsive. Most on here know our customer service is beyond reproach so we found your premature post a bit puzzling. Your proposed that perhaps it was the esc hitting the boat on the inside during shipping. We took that to heart and now all esc's are bubble wrapped inside the boat before shipping. Thanks for the suggestion!

Sailr is spot on re higher c lipos & you will blow the esc in these boats going higher than 25c. Ask me how i know, I went from 25c to 45c fully understanding i would probably blow the esc as i intended replacing with a better higher amp esc anyway & as expected it blew a few weeks after. Re higher c lipos i went from 25c to 45c & now using 60c & saw higher speeds with each increase in c rating on the same size lipos. Martin.

[Boaterguy]

the C rating will not blow the ESC, the C rating is how much a battery CAN discharge, not how much it WILL discharge.
Again use the gas tank metaphor. a gas tank with a large nozzle/ hole can put out more fuel, but the gas won't come out on it's own, but the motor will draw a certain amount of gas out of the tank.

[martin]

I think youll find that the 30amp esc in these boats cannot take the extra amp draw that the motor can draw from the higher c rated battery & ends up blowing the esc. Martin.
