Brand New Pro Boat Mystic 29 up in smoke !!!!

[HUNTER]

thinking of getting a mystic can you tell a newbe why they would say the venom 2s 5000 40c was the wrong battery?

Unless they're a hardcase pack they should be fine. Who told you they were the wrong pack?

[gzee]

they were talking about batts. and blown esc's. >another question why should you not use hardcase packs

[Steven Vaccaro]

I use two of these esc's in my twin mono and some rather large props. So far they are are great.

What we are seeing is that esc companies are starting to shy away from wanting to warranty burned up esc's like that.
There reasoning is that all of them are power cycled/tested at the max loads. So they are assuming that if that's the case, they should run fine if run at their respective ratings. Is it right or is it wrong? I'm not sure. Just passing along some info.

Just to add on this conversation I am running my Pro Boat Mystic with two 2S hardcase 5000mAh 50C batteries from "John the Battery Guy" and a X642 balanced prop. I am not having any issues with heat, motor, ESC and batteries are almost as cool as when I put the boat in the water. HOWEVER, I am having issues with the ESC. First time motor just quit, released the throttle for about 10-15 seconds and she ran fine for about another several minutes, then quit again. This repeated in about the same time sequence two more times until I brought it in. All cool as a cucumber. Day two, running boat about 5 minutes and it went full throttle, no rudder control. Luckily my lake has a thick layer of weeds around most of the shore and boat went in weeds vice bank at full bore. Motor cotinued to run full speed and then I thought to try reverse on the transmitter (I know the ESC has no reverse) and the motor stopped. After several seconds I had full control and ran the boat, which was on the other side of the lake, out of the weeds and to me. Opened hatches up and all electronics and batteries still cool as a cucumber. So if Pro Boat thinks there ESC fails because of too much pro, not enough battery or whatever excuse they find, they are crazy unless an X642 is too much prop and I don't think so.

Can you give me any more info on John the Battery Guy like prices ect.

Oh, him again. Are you getting 20 minute runtimes out of those packs? FYI, they're Gens Ace packs with a new sticker on them. Look closely at this one:

And then at this:

20 minutes? Yeah, no.

The X642 is too much prop for that 1800KV system for anything longer than a 2-3 minute racing situation, especially if you haven't replaced the 3.5mm contacts on the motor/ESC... That prop has a high pitch ratio and loads the 1800 system too much for "sport" running...

[gzee]

Just going to say that because i just got Gens Ace 5000mAh 40c for $34 from Hobby Partz.Same batt. just his sticker .

[sft2]

Yup, other than the sticker, my GA 5aH 45c packs are identical, including the charging harness that he sends with them. Don't use that harness in the boat, though. The bullets aren't going to handle 65 amps for long. I made new harnesses with 12g wire and Castle bullets. His must have some magic to be getting 20 minutes, I get 6 minutes.

[BBQSteve]

Darin,

I don't know what race situation has to do with it, but my Mystic running stock and a X642 prop with the 50C 5000mah batteries will run as cool as a cucumber greater than 6 minutes full speed in an oval. Anyone in the Tidewater area is welcome to come watch anytime. I know you have more experience with these electrics, but I am just telling it as it is.

sft2, I think that 20 minute thing is a copy from one of his car ads where you run one battery at a time for 20 minutes total. Anyway I'm happy with my performance.

[JimClark]

Not sure why you guy's are so into the hard case batteries. if you get them wet they are pretty difficult to dry out unless these cases are better than the ones I have seen

Jim, I only use hardcase ROAR packs because I have them left over from my Slash. The next packs I order will be nekkid. My two best packs spent a few hours underwater last weekend and seem dry and perfectly functional, though.

[BBQSteve]

Not into hardcase, just what I ordered for what I thought was a good price for what I wanted. I keep the water out of my hulls.....or at least try to.
