Default Lightest battery load.

Show me what is your lightest battery load to power E-models. I'm more into heavy duty gear, but in recent times build many micro size models from tiny EDF jets to my other passion, flying 3/D aerobatics of the lightest kind requiring not only lightest power and electronics but the source to run them ''slow-low and very close"!

The lightest scratch build creation I came so far in EDF jet is some 270 grams AUW, running pretty hot on 30mm fans off 3S/650 to 850 mA packs of highest C rate I can get hands on for 2 to 3 minute fly times. Anything larger is impossible to fit in due to the restrict space and CofG.

3/D wise, I managed much better with reasonably sized models at 850x100cm (S/L) at mere 130 grams plus mini size 2S/260-300mA lipos as some 17 to 25 grams. My new target is to come closer to 100 grams AUW, but not lower as I build these models only for outdoor flying in calm conditions so even carrying these type of models to my flying site creates enough head wind,

Micro EDF jets converted from toy gliders to full RC power running on mini 3S lipos.

Not much space for the power source.

Rather stressful little toys to fly.

Most exiting is always the sling shot.

Few packs to run micro fleet.

Super light outdoor flyer on 2S/300.

2-4 minutes of slow-low-close fun on tiny packs.

Fleet of my 3/D micros is getting lighter day by day with new creations.

One of my early heavier build on 2S/550.

A real dog to fly at 550 grams on 3S/1Ah.

Slight lighter but still a dog on 3S/850.
LOL.
Currently while local H/King warehouse is going bust, closing, I find very difficult to replace any type of lipos with more stock so making most of what I got on hand.

My latest delicate creation is nearing completion for my lightest battery loads.

My latest Dead Calmer getting stiffer with more carbon.

Another great maiden flight with my latest creation on the lightest battery in my collection.

3 to 4 minute flight time on tiny 2S pack with my delicate creation.

Working on the lightest in my DC Series, this one will be powered by 2S/260Ah pack, hoping for 100 grams AUW or near.

Another 'Delicate Creation' in making.

100g target.

Funny thing this eve, flew three "DC" models before dark, so next one was this "B&W" ( top pic) on 2S/260, hooked it up 3 times and no go! Just kept on beep-ping! I said bugger, must have lost its bind.
Back on the bench, just realized I took the wrong TX to fly it! LOL. Didn't check its log book before taking it off the shelf. LOL. Too many models, LOL.
