little rustler could outpace my kia like it was standing still

Not to mention, my Rustler, was in that video!

Boy, this rustler should be in the Hall of Stupidty of Mike and Ben! (No offense)

It's a beast though......

I guess my blunder, was when I was resting my hands on the back of my Rustler tires, for a little to long, I had a mark on my hands, and I just couldn't get the flat spot off the tire....

I actually drilled a few holes in the sidewall.....

Then I tried to get the flat spot out, again, by just pressing, and little did I know, it actually came out...

Now I have a few gashes in my tires....

A few weeks ago, I was attending my first race at a new track with my 8ight-e. I had been practicing at said track for about 2-3 hrs and felt pretty good about it. I was putting down some good laptimes imo and not really crashing.

Well, the first qualifier comes around, and I am doing a few practices laps/getting my transponder in the system. The last half lap before we line up to race, I hit the big triple in front of the of the drivers stand. (Side note: when I say in front of the driver's stand, you literally could touch the cars if they hit the jump at the closest approach.) I hit the jump at a weird angle and smash my buggy straight into the wooden stairs leading to the track. Needless to say, the deceleration was brutual..lol. I broke my front bulkhead mounts and bent the crap out of my front shock tower, right before my first qualifier. Doh!

The announcer made a wincing comment, and later on, the people in the enclosed shop 100ft away said they heard it! Pretty embarrassing. Luckily, i was able to compete in the second qual and get 3rd in the main via some handy ziptie placement and CA glue :)

bump!

Bullet connectors are cheap, can handle a lot of current, and are easy to use. They are, however, very easy to short..

And that is why as of today there are less bullet connectors on my e-bike and more andersons.

Hey Metallover, cool tattoo!

Man that must have hurt... What voltage was it?

[Metallover]

I have six 5ah 6s lipos on my bike. It was at 66v when I shorted it. There was a HUGE flash/pop/spark and it scared me like noneother. Thankfully, it didn't hurt as I wasn't directly shocked and I wan't wearing any metal (rings).

The worst part of it was trying to wash the stuff off! It didn't come off until the end of the day after washing my hands vigerously 6-7 times..

The worst worst part of it was that it fried one of the connections inside the pack so I had to open it up and re-solder the joint. I wan't sure if it would hold up at first but it can take the limited 20a the bike pulls.

holy

ouch, I don't think I wanna solder 66V packs...

That WOULD be a great tattoo though..

Wow 66V?! That is actually high enough to electrocute you... I'm sure it was burned into your skin which is why you couldn't wash it off easily. Thankfully I haven't fallen victim to a large discharge like this (yet). I do have plans for a rather large railgun though...

Way back i tried backflipping a maxx, only got as far as nose strait down and hit the ground like that.

2 half maxxes where the result.

yikes. i have 7 packs of 6s lipos, all 5k. two other 5s lipos too. and all with 6.5mm bullet connectors. i'd better double-check the shrink wrap tonight to make sure no metal is exposed!!

my biggest blunder was using a novak discharge tray to discharge a 7 cell racing ni-mh pack. i don't know what happened - the polarity was right, but somehow a few of the cells fried instantly!

Electrocution is a result of the current, not the voltage. A 1V high current shot is much worse than a 400V low current shot.

Yup, 30-60mA of AC current is enough to cause muscle paralysis (can't let go of circuit and can't breathe) and 100-200mA will fibrillate your heart, which for the most part will kill you unless you are defibrillated. DC current values are slightly higher but still relatively low.

That said the voltage has to be pretty high to overcome the resistance of the human body. However if you are wet that value can come way down.

Given these circumstances I don't think the 66V DC from the lipos could electrocute you. Even if he was wet, standing barefoot in a puddle only about 5mA would flow, and again that's absolute worst case scenario.

My RC Blunder

One of my RC buddy's has a HandyMan business, My biggest blunder was hiring him. He come over Monday and Demo'd and gutted the entire bathroom in the master bedroom. He asked for a few hundred bucks, I cut him a check for $1,000.00 to cover a few days labor and materials. Well, I haven't seen or heard from him since.

Some of you seem to be missing the point of the thread?

An e-bike using RC components doesn't count, and an RC buddy screwing you doesn't count.

OK I guess we'll take what we can get hehe. ML get some rubber gloves, and Bondo get some better friends!
