Perfect conditions, lots of small pockets of lift, a great site, well run and very friendly

Electric power

I have just fitted an  EMax GT 2826-06 motor to Shadow F3J, it draws 53 amps from a 4 cell 2,2amp lipo with a 14 x 7 thin carbon prop and gives a climb of 2100 feet per min

It's about one horse power which would lift 1 pound to 33,000 feet and would lift 6 pounds, the weight of my shadow to 5,500 feet, this work out at 38% percent efficiency   

* Type: EMax GT 2826-06
* Class: Brushless
* KV (rpm/V): 710
* Number of cells: 4S to 5S LiPo (11.1V to 18.5V)
* Maximum current: 52A (for 60 seconds)
* Constant current: 42A
* Dimensions: Diameter 35mm, Length 49.5mm (68.25mm inc shaft)
* Shaft diameter: 5mm
* Weight: 175g
* Recommended ESC: 60A
* Prop range:
4S LiPo up to APC-E 14 x 7

below is the calculated performance from http://brantuas.com/ezcalc/dma1.asp this has over estimated the current a little, but I am using a very slim prop; props vary in section and cord

New photos for August see picture viewer  4 more needed to finish the slide show

The flat field duration local record stands at 1 hour 9 minutes for this year by Sqeela with his Electric Shadow. on Minchinhampton common from 150 metre launch.
My AVA did a longer flight but was flown by 4 people 

This is for hand launched, bungee or one short motor run on a flat field without the use of slope lift

  Adam holds the HLG record at 14 minutes

The local height record for this year is held by Chris Bishop at 2953 feet attained at GMFC

Slope Flying & flat field
Monday

A good afternoon on Minch: Sqeela trimmed out his new Blaster2, adding a little weight to the tail end to adjust the C of G 

 I had a go at beating his 1 hour 19 minutes, I got close 'but no cigar'  with my Supra  loosing concentration and failing to find lift near the end, I was up over a 1000 feet and struggling to see it at times against the blue sky
I got an afternoons flying with it with only 40 seconds of motor run, taking just 500 ma from a 1.6 amp 4 cell battery

Tuesday
Not a good day at Selsley, the lift was very poor; Brian's graphite went OK but even Guy's Highlight failed to stay up at times, I had a struggle with my Pegase and walk down the hill many times after failing to find enough lift

brian-selsley-graphite2.jpg (94230 bytes)  brian-selsley-graphite.jpg (94923 bytes)  peg-selsley.jpg (142130 bytes)

I had a go on the common in the evening with my Electric Shadow

The 1st chart shows my climb, I reduced the climb angle at 130 metres, the motor cut at 150 on the limiter and I zoomed to 185

A brief outline of zoom.

The approved limiters have an anti zoom facility, that is the software in the limiter analyses the rate of climb.
So that if you are 'rocketing' up the limiter will actually cut the motor at, say, 170 metres so that you actually top out at 200 metres with an allowance of +10%.

Therefore it is virtually impossible to (cheat) zoom by fitting an overpowered drive train and busting the height limit. Such as you can do with the likes of a CAM limiter which switches the motor of at the prescribed height and the excessive speed and kinetic energy of the glider will carry it up a further 40 - 60 metres (or more).  Similar to the ping off a line.

This means that there is no point or advantage in spending a fortune on expensive & powerful drive trains as all you need is a budget motor that will get you to height in under 30 seconds.  This was done specifically to keep costs down and keep everybody on an equal footing.  There is no point in getting to height any sooner, as all it does is extend your (unpowered flight) gliding time

Hope this helps.

If you need a more technical explanation of how this development was made and how it works Martin Bell will be able to explain better than me!

The second chart is my last flight at 7.45PM, there was still very weak thermal lift and I easily made a 10 minute flight from a 16 second motor run

Thursday

i took my shadow to the GMFC; the wind was a little strong and I struggled to find lift and I was scared of chasing it down wind

Sunday
Haresfield and Frocester flown

I arrived at Haresfield at 3.30 with Andy G so we must have just missed you. We went round to the main slope, and the wind was indeed off to the right. However, that didn't stop us having a go! I flew my Wildthing and Luna, and Andy flew his Zagi. The lift was a bit iffy, so we moved back to the bowl. Lift was good here, but I hate this slope, but at least I got to fly one more plane that I have converted to a Jeti receiver (to go with my DC-16 transmitter). We left around 5pm.
