Freak Accident

[heliman]

Today was hovering my 500 than suddenly heli went crazy!! Luckily I wasnt hovering it too high, landed hard.

When I took out the canopy I found this :


Battery connector loose


Rear torque shaft bend

Front torque tube also tio siong. Damn sian ah...

Sad to hear about the crash. This is the common issue with deans although it doesnt happen.

Hope nothing major was damaged (except the tail )

I think battery connector came loose resulting in heli spinning widly than hard land, rear torque shaft bend and thus resulting in front torque gear kena stripped.

change the connector type

erm , i suggest you get rid of the deans and change it to something like EC3 styled connectors ... like this : (pic below)

Advantages:
A: they are alot easier to solder than deans ...
B: red coloured ones can handle up to 80A/100Amps depending on which type you buy..
C: they are easier to pull out and attach

Disadvantages:
A: you gotta resolder alot of connectors if you got alot of batttery packs
B: gotta find the connector for your charger. or resolder your charger port.

honestly , after buying some turnigy backs from .. with EC3 connectors its really easier to connect/disconnect

Bro: where can get in SG ?

Not sure if jet hobbies have them. I bought mine from Hobby City (HK) but mine is EC4.

You might want to consider Anderson Power Poles (sermos). No need to solder. They work efficiently even rated for 45A I've used them for even high AMP application. I have it on my 450 and my Monster Trucks...Singapore Hobbies have them...

does it look like this

[jffry7]

Yup the connectors at the bottom of that photo. They have the connectors only at the store but not on the website. You might be able to get cheaper ones online.



this is the actual connectors...
