During the preceding evening we had played
around with the fuel system of the Profi model as we believed that the
problem of the inconsistent hot restarts was down to the exhaust priming
function. All F2C models are equipped with an all in one fuel system
which includes the tank, refuel valve, cut-off reset and exhaust prime.
The Profi also runs on tapped pressure from the engine just to
complicate things even more. Believing that we had pinned the problem
down we used our official practise time using the Profi model but were
unable to completely cure the fault. Occasionally fortune does smile
upon us as a call was made for a volunteer team to make up an extra
We volunteered and were rewarded with an
extra official practise time. During our third heat the rising
temperature caught me out somewhat and the engine had to be cooled with
water during the first pit stop and then be again cooled with water and
a compression adjustment during the second. Despite these measures the
engine was still going over the top (overheating) and during a third pit
stop a lapse of team understanding caused the model to fail to take off.
This then was effectively the end of our participation in the 2015
Thursday 26 Aug 15. Sunny and very hot.
This was a free day with no planned
flying. Effectively this day had been programmed in for the purpose of a
reserve flying day to cover any problems with weather. We therefore
watched some of the teams practising. A good routine on my part as there
is a lot to be learned from many of the teams whose pitmen have been at
it for much longer that me. A trip was also made to view some of the
combat (F2D). During the previous few days there had been a couple of
incidents with the F2D which had required those involved to receive
hospital treatment. Therefore being a well mannered gentlemen, I
insisted that Sue wore my pitting hard helmet whilst we viewed the
action. Unfortunately I was unable to obtain a photo of this due to the
pressing requirement to keep my various bodily parts attached and pain
Later that evening we all attended a
seminar upon the future direction of F2C.
There are changes coming, mainly driven I
fear, by persons not actively involved in the sport and more for
political reasons than for racing improvements. Time will tell.
