More R/C Setbacks!!!

Normally just a post a day gets written, but some topic/news came to mind that I wanted to share, so three or four posts will be written tonight. First a bit of bad news about my Slash. After the first run of the day yesterday, I put the batter on the charger, them when it was done, I went to put it in the truck.

 

While I was hooking the connecter to the pack, the red (Positive) wire broke, coming out of the connecter. Love it when sodder breaks! It looks like I’ll be down until I order a new battery pack, which will be in a few weeks. That or get a ride to our local hobby shop.

  1. Solder. Similar problem i had, but the solder didnt break, it melted. When i ran the steeper pitch longer rake propeler on the revolt 30 boat it does a few things. First off it moves more water and in turn makes boat travel further per engine revolution and increases speed. The other thing is the bad part, with those pay offs for speed comes the sacrafice. The motor is trying to reach its optimal rpm, to do this with its newfound load the motor will draw more amperage off the batteries. Drawing excess amperage creates heat, in the motor, lead wires to motor, and batteries. If the temperature exceeds the melting point of solder….well there goes your soldered wire conectors…may have happened to you.look closely at connecter it may have melted, if so your engine is drawing to many amperes…youll need to find out why.

  2. Not sure if u know kenshin so ill tell you a bit about electricity, pertains to all but i mention it more or less with regards to your slash truck. This is in pretty much laymans terms..lol.. Ohms law..it takes 1 volt to draw 1 ampere (amp for short) thru 1 ohm resistance. Voltage is the motive force in which posotive wants to get to negative or negaitive wants to get to posotive. If voltag is increased enough it will actually jump thru air itself, aka a spark or arc. Amperage is the amount of flow of electrons once a circuit is closed. Think of it like a garden hose and a fire hose. Garden hose, less flow..low amperes. And fire hose, big flow, higher amperes. The more amps a load(motor, lightbulb for instance) draws, the larger the wire guage must be. Light bulb,low amps, thin wire…big electric motor, more amps, thicker wire…i think you get it. Ohms are a unit of resistance on a closed circuit is made. If reaistance is to high elecctricity will not flow. Load in a circuit is resistance. Think of those electric little slot cars on the plastic trac you might of had as a kid. The trigger you had in your hand was a device controling resistance, it varied resistance, and a variable resistor is called a rheostat. Squeese the trigger full, low resistance, greater flow of amps, car goes fast….less trigger pull, higher resistance, lesser flow, slower slot car…resisters work by changing the electricities power buy converting into heat. Remember E=mc2. Energy cannot be created or destroyed, it can only change form. A resistor changes the higher flow of powers form into heat, therefore letting less power thru…. Your speed controller on your car is a rheostat…or variable resister..im sure youve heard ppl say if you get shocked its not the voltage that hurts you, its the amps…that is abosolutely true. A good example is during a thunder storm. A massive amount of negative particles collect in the lower half of a cloud, and posotive particles stack to the top. To counter this posotively charged particles collect below the cloud on the grounds surface. The massive collextion of negative in the cloud wants to find ground, opposites attract…the coltage increases to a monumental level until it actually overcomes and actually flows thru open air to reach the ground…voltage is massive but nothing has happened yet so traveling out from the cloud is a path called a stepped leader, it searches for the ground to meet the posotive. At the ground the posotive send up a short streamer to meet the negative stepped leader. Once contact is made “caboooom” the lightning stoke, now and only now a path has been created and a massive flow of amperes unload to the ground… I hope this helps you ot dude…
