Default Ntc3 ran away

So after about two years up in the shelves i decided to start up my Nitro tc3 plus and i was running it in the parking lot then all of the sudden it went full throttle and just kept going and hit a curb. Thank god nothing broke.

But my question is i probably do need a new controller and receiver and i wanted to use the one from my lst2 but that car has been in my garage for 2 years also. would it be save to use the receiver and controller from the lst2

It sounds like the receiver battery took a dump in your ntc3.
Swapping out the radio and receiver for something
better is always a good thing. But if you don't loose
the AA batterys and that problem prone AA battery
holder you will be asking for more run aways.

Or you could buy a OFNA micro failsafe that will prevent runaways due to low receiver batter voltage or loss of signal. Cost about $20 or so.

Once you program it, it will move the throttle to the brake position if it goes into failsafe mode.

fail safes work a lot better with a rechargeable battery pack...some of them don't even work with AA batteries due to the discharge curve..be warned..

Smile runaway

i did away with the AA batt pack soon after getting started in rc cars.

my first runaway came after a hard, 'high g force' turn caused my batt wire connector to come apart just enough to leave my throttle wide open from last radio command. the next few moments were not pretty and the carnage not on my 'want to do again soon' list. after 'WHAT THE..........'. i walked over to my car and tried the controls....the batt reconnected from the force of impact! i now without fail put a piece of electrical tape on the connector.

some servos will allow a spring or 'gummi band' to pull the carb closed but others won't decrease throttle if carb was 'open' when servo power ceased.

I've had about 2 or 3 of these in the last 20+ years, never fun.

Ever notice how runaways only happen at full throttle? Never at half or quarter. And the car always seem to find the hardest object out there to stop on. Oh the RC mysteries to ponder.

Send a message via ICQ to valk Send a message via AIM to valk Send a message via MSN to valk

the real fear is when your in a parking lot that still has cars/people around... np if it smashes itself on a curb, its when it goes barreling into someones property or person at full throttle.

I accidently side swiped my foot when i first got the thing in the summer and i still have the scar on my toe.. ouch.

at least its cheap to fix. i bent my chassis almost in half from the impact, but had spares from various rollers lol.

Default Maybe not for this thread.

Last time this happened to me. I was running a 28 inch airboat. 10 inch prop swung by a k&b .61 doing big wide full throttle circles toward 2 guys in their small fishing boat. I was lucky and it died within 10 feet of them I thought it was gonna join them in the boat. What a mess that would have made.
