35 MHz interference update -- Dave Armitage
ICASA have recently done a survey at Midrand Model Soarers field to ascertain what was causing some heavy interference on certain spots in the 35 Mhz band. It was found that ESKOM seemed to be causing the problem with arcing on some of their ultra high voltage power lines. I have requested a full report from ICASA. At present they state they have informed ESKOM of the problem. ICASA want to do another full test at the site before issuing a report. On receipt of that report then I will make it public.
Another site that seems to be experiencing some frequency related problems is JOMAC. This site is also near a heavy concentration of high voltage power cables. It could just be possible that the same sort of hassle could be happening there.
I am awaiting fault reports from pilots at JOMAC before initiating a survey there.

World Model Pylon Racing Championships -- Peter Eagle
Hey all pilots with any interest in our WC teams
You may know that SAMPRA as the pylon racing SIG of SAMAA currently has an official, 3 pilot South African team at the pylon racing world champs at AMA headquarters, Muncie, Indiana, USA.
The team of Trevor Budd, Andre Nortje and Russel van der Westhuizen as well as Wayne Wilcox and other helpers and supporters have spent huge amounts of time, money (their own) and effort to get to the world champs. The team has been at Muncie since late last week and have been using the time to practice and adjust their equipment to local conditions. (Elevation about 1000 feet or less, hot and humid climate at this time of year)
After official practise yesterday Trevor reports via SMS " Some times from today in Richards Bay like heat - Trevor 1:06 (66 seconds); Andre 1:09 (69 seconds) and Russel 1:12 (72 Seconds) Top 12 all running 57 to 60 seconds. Please let the guys know."
I then posed a question regarding reliability and repeatability as often the very fastest have issues getting in all their times and hence a slower but more reliable setup will make for better results in some cases. Trevor replied " We are getting there. Lots of broken pipes and engines in the beginning but we are now happy with the setup. A bit slower but reliable"
I trust that all pilots with the slightest interest in these amazingly fast, expensive and temperamental planes will wish our team all the best of luck.
I will post further updates as I receive them but the German team has a regular daily posting on http://www.rc-network.de/forum/showthread.php?t=73140
Update 27 June 2007 -- link to official web site here.
