Hi All, This is my first post here, so forgive me if it's wrongly formatted or the technique stinks!!

This is my first foray into Electric flying, in fact I haven't flown an aircraft since I did a bit of Control Line stuff back at school - some 40 years ago.

I've just completed a Wattage Impress trainer with the Electric motor that was supplied in the pack.

When I run it up to cycle the flight battery, after a short time, the ESC custs the power and the motor stops. Bringing the Throttle back to zero for one second and then back up starts the motor again.

I am using a 7 cell 8.4v 800mha set, with a Jeti 350 ESC and the supplied motor. The alarm tone suggests that the peak current for the ESC has been reached, but I was told that it should carry the load. The only other thing is that I'm cycling the new battery on the ground, so maybe something is overheating?

Has anyone any thoughts??

Cheers from the UK

About the worse thing you can do to any electric setup is attempt long runs without any cooling air. How long is "a short time" ?

It's most likely that the battery is losing voltage and kicking in the LVC (low voltage cutoff) on the ESC. This may be overheating of battery or esc. It's also possible the battery is not fully charged. The one thing it isn't is over current on the ESC because that battery will never deliver more current than that ESC can take.

What type of battery is it and how are you charging it ?

Whatever you are probably better off going flying.

Many thanks for the suggestion. I've done the prop off run in. I
think now I have sorted the problem out.

I was a little confused by the instructions that came with the ESC,
which said that only some of the range had BEC included. The notes did not specify the 350 as having the facility, so I had both the Flight battery and the Receiver battery installed.

Removing the Recever battery from the set up has cured the cutting out and the motor appears to have a greater rpm range.

With a bit of luck, weather-wise, I should be able to go to the
flying field that is used by the local Club on Sunday and introduce
myself and see if they will allow me to join and give me some
instruction.

I me a couple of the members in the model shop I bought my kit from amd they said I would be most welcome and that they would be delighted to train me.

The weather here is bad just now, with heavy rain, high winds and temperates of around 9 celcius. Hope it gets better as Monday is our May Day public holiday, so no work!

Happy flying

Ric

Yeah Ric, we have the May Day bank holiday all the way down here in Berkshire too . And the weather's not much better ! Good luck at the club, most of them are pretty friendly.
