Electric Flight Technical / Re: Rookie ESC/Motor connection question
« Last post by itsme on Today at 22:07:52 »
Thanks for the feedback guys.

The model it is installed in is a Ripmax Wot 4 EP/GP which is specifically designed for electric set up and has an additional cooling hole on the underside of the fuselage plus an extra air intake in the cowl, so hopefully that will suffice.

All the components such as ESC, motor and battery are as recommended for the Wot on the Ripmax web site so I'm hoping not to have too many issues. The motor comes with a suggested range of props so I'll try those out with a meter fitted to monitor amps.

One other rookie question. Having checked the balance on the completed model, I will need to add extra nose weight and rather than using dead weight (lead) I plan to use a flight battery to replace the BEC feature on the ESC. Question is which wire do I remove, red, white or black? I'm guessing black and would cut up an extension lead rather than the ESC lead. Thoughts?

Cheers

Ian
Bit complicated for no real reason. Just add some lead.

You need to remove the red lead, this is the positive, leaving the signal line and ground. Rather than chop up an extension lead, just ease the positive pin out of the plug and tape it back to the cable out of the way.

Just to let you know that Joe took his Silent Flight Electric “A” test with me on Saturday. This was his second try at it and he passed with flying colours. It just goes to show how important preparation is. I am sure he wouldn’t mind me saying he was a little shaky the week before but this time he was spot on.
Congratulations Joe.

I would strongly endorse the ESC cooling requirement.
An ESC creates about as much heat as the brushless motor and to make matters worse it does not have the advantage of rotating parts to swirl the air about to dissipate the heat.
A positive airflow over all the ESC is important.

Excellent day's flying at Thurnham yesterday amongst friends and blessed with fine weather.  :)
However a couple of crashes occurred :'(
Si wiped out my poor little Graupner 'Terry', although I did offer it up as a sacrifice in the combat session and the attack on my tiny aircraft resulted in a vertical dive to halfway down the slope, but it is repairable and will live to fly again another day!  :nananana:.
Mike from the Bickley club brought along his 1/3rd scale K8 which was unfortunately caught by a gust just after launch and it side-slipped into the ground making a mess of the fuselage, but the wing and tail group survived intact. Mike says it also is repairable and that he'll have another fuselage built in a few days and it will be back on the slope again in the very near future. :af

When Joe and I arrived at 9am, we noticed that there was a lot of fast food joint's litter dumped in the lay-by, thrown there by the night-time visitors to the lane.  >:( >:( >:(  So when I left at about 4:30pm, I picked up all of it and on the way home, deposited the couple of bags of rubbish in the local litter bins. It will be interesting to see how much accumulates by next weekend!

A variation on the timeless classic that is the 'Slow Poke'. From Durafly...this new version of this retro flier takes minutes to assemble from the small number of components in the box. For relaxed easy SLOW flying it's fantastic. Super slow fly-bys, tight turns and easy inverted flight all make it really enjoyable to throw around in a relatively small space like my local club field.

Here's a PDF version of the list for those who can't read excel files. I had to shrink it so that the columns fitted on one sheet, so the text may be a bit small. But you can always zoom in. Unfortunately the PDF version won't offer filter and search functions, so you just have to read it.
