 Posted: Fri Aug 15, 2008 9:44 am Post subject: Progress report S5 test flying |
 |
|
Just want to say that test flying of the S5 (912S - fixed pitch) is going fine and that a number of tips from the list have helped. I asked for advice re directional sensitivity on bitumen and based on that advice, loosened the the tension on the tailwheel steering spring and reduced tyre pressure. Seems to have helped and now after 7 landings, all on tarmac, I'm getting the hang of it.
Performance is great with 1,000 fpm and about 90 kt cruise at about 75%. None of this calibrated yet but it will be over the next six months and 50 hours of test flying.
A problem I had was the low fuel warning light coming on - the light sensitive type. The header tanks was always full after landing so eventually, after reading the archives, I covered the header in black plastic and this stopped the low fuel warning coming on. My next task is to empty the tank to ensure that I haven't actually stopped it from performing the function it is intended for.
I've also had wildly varying temps and pressures for oil and coolant and traced it to bad electrical connections.
The plane is wonderful and all that I had hoped for. Can't get this grin off..

Great to hear that you are back in the air Michel. An example to us all. One day this Kitfox may fly north and if so it wil be dropping in on you.

On my series 5 with a Maule Tundra tailwheel I have significant tailwheel
chatter on landing if the springs are not tight, so this might be something
to keep in mind.
Header tank, I covered with aluminum heating and cooling tape. Very
effective for blocking out light. Also some flickering is normal, and seems
to increase as you get lower and lower on fuel
Don't get complacent! Remember your engine install and everything else
is still new. You can get mighty comfortable pretty fast when you fly it
every day, and things can still fail when you don't expect it.

You're right, it is very easy to get complacent when everything is going well. Cowls are coming off every couple of hours so everything can be checked.
I've just drained the header tank to check the low warning light comes on, and then let it fill again from the mains and watched the light go out so I'm now fairly sure it will work as intended.
It is such a good plane. Kerry.
