The peak temprature has fallen quite conciderably

Now the question is why was it getting so hot on the previous Sunday? I think I've found the answer, The back plate of the spinner was very close to the cowl and while it ran nice and free on the bench I think the cowl might have expanded while sitting in the hot sun and was binding slightly. The Sunday when I first tested it was quite hot. I can see where there's a bit of a rub mark on the very front of the cowl as well, that could have been just loading it up enough to cause the trouble. On friday it was sitting in the shade and it also wasn't as hot a day as Sunday. I've shifted the collet out a bit on the shaft so it has more clearance and should cause no further problems. I've posted graphs from Fridays three flights. I'm much
happier with it now !! I will be setting the timer a bit shorter tho' , down for 3 mins to two so I don't flog the batteries so hard
