A landing light can made from a boat searchlight. I did have two more tips but forgot what they were just now.

Here we are ! To ensure formers are the same both sides Draw half a former to a line Now fold the paper along the line and cut out the former through both pieces of paper. Unfold and you have a complete former. The shampoo in the bottles makes good spot/stain remover from mattresses and upholstery.Scrub in with a toothbrush and sponge out with a damp cloth or sponge. Mix the rest with your car shampoo or use as a shamp for the car.. Brilliant.

Hi All,

New props ordered, only 1 in stock so I will have to wait until I get them, and now the weather turns.

Regards

Robert

Hi All,

Props arrived during the week plus a new 4s 5000 battery pack.

I have done some static thrust tests with my watt meter attached, below are the results

3s original 7x5 2 blade props 2lbs thrust drawing 15.8Amps and 191 watts = 27watts/lb

3s with 8x6 3 blade props 2.6lbs thrust drawing 27Amps and 315 watts = 45 watts/lb

I had to trim down the new inner props to 7 3/4" to give clear the fus

4s original 7x5 2 blade props 3.2lbs thrust drawing 25Amps and 400 watts = 67 watts /lb

4s with 8x6 3 blade props 4.8lbs thurst drawing 42Amps and 695 watts = 99 watts/lb

The new battery pack is 4ozs heavier than the 3s which brings the new weight up to 7lbs 4ozs.

So with the new battery and prop set up the power gain is 72 watts / lb. I'm so glad she did not take off on that maiden flight.

I would welcome any comments on the above results as I'm still learning this art of electric flight.

Regards

Robert
