Much Marcle cancelled
Unfortunately HMAC committee have had to take the hard decision to cancel this years show at Much Marcle.
The field is in a very poor state following the annual steam rally that took place over the weekend of 18th and 19th July, the field has muddy ruts in places over 18" deep, and the crowd line/trade line is a 30-40 metre wide strip of muddy rutted bog the full length of the field.
There was no way that the field can be repaired in time for our show, it could possibly have be made flat again but it would not be grassed so just a small shower and the foot traffic alone would result in it again being a mud bath, and we just can't bet against the possibility of rain! We are very sorry to have to cancel especially after canceling last years show on the Thursday before, again due to the field conditions.
Please let anyone know about the cancellation that doesn't have internet access as there will still be show adverts in the models mags between now and the show weekend.
Thanks Antony

Monday
Plenty of Lift at Frocester

    

Wednesday an afternoon of thermalling on Minchinhampton common.
Guy was pleased with his Riechard Champion, a change from Ni-mh to lipos has saved 300 grams and improved the way it thermals

Thermal comp against Malvern SA at Fish Meadow,  9th Aug.

A very good day, small thermals and some big ones, many slots were flown out. We were  1000 points down after 2 rounds but got them back with the results decided by the final slot flown by Chris Bishop

Lipos
I found this on a Forum, most statistical evidence advice is for laptop batteries 

The chart shows graphically what I was saying (in fact, this was one of the titbits of info that I gleaned my knowledge from.  What its saying is a low temp storage with mid charge level will retain 98% of useable capacity (that last two words is missing from this chart, I think it was in the lead up description), whereas a fully charged battery stored at 60 C will be down to only 60% useable capacity after just 3 months.

That chart though is more aimed at laptop batteries, where they are always fully charged and the average running temp is around the 60 degree mark.

In our game, I keep mine fully charged, but store them in a cool metal container that would average around 15 degrees C.  Based on that chart, this will only drop to around 90% useable capacity after 12 months. Not taking into account that 50 to 100 times during that time they will be run down to 20% capacity and recharged (based on using each battery twice a week).

In my mind this is not that much different to the ideal storage habits, that will drop to 98% useable capacity after 12 month.  So in reality for our usage type, providing you don't store them on the dashboard of your car when not in use, you will not notice any real diference.

Analysis: stored at ideal charge, comparing 0 degree storage temp to 25 degree C storage temp - difference of just 4% total useable capacity after 12 months.

comparing the same 0 degrees half charge voltage to 25 degrees C fully charged, 18% difference in total capacity after 12 months.

Since we only avery 2 years useable life, I don't see that the effort is worth worrying about.
