Lots of things being worked on at the moment

With the LAA flight test forms about to go off there are lots of bits to complete …

With recent incident I read and the factthat I have put the wheels on and off around 3 times so far another check that all 12 bolts are tight … checked ok ..

Both footrests prepared ready for fitting once i confirm the lie of the material

Covered dashboard having fittings re-applied ready for wiring up

Reckcon lower body and sides will take about 3 evenings

Weight and Balance and C of G – Late night weigh in :-)

After all that covering .. time to re-weigh and see where it all settles out in terms of weight and balance.

Got 125Kg on each wheel and 10Kg on the tail. So all up it’s not looking too heavy.

EMPTY – well allowing for me as a 75Kg Pilot sitting in P1 AND with a tank of say 40 litres of fuel the CofG comes out at 185cm from my datum (rear of the prop flange) ..the TLAC stated CofG is between 180 and 190 from that point ! so smack on midway ….

Trouble is life isn’t that simple and you need to cater for the normal ‘flight operating window’ ie taking off with a load of fuel that then burns and changes the CofG

The ‘trick’ now is to use the LAA template to work out the worst case forward and worst case rearward CofG points. If fuel is burned off to say 1/3 of the tank the CofG moves rearwards by about 10-12 cm ..I am going to cross check this with Paul to make sure my figs /maths are correct as ideally i do not wish to put a chunk of ballast in the nose 🙂

Luckily the P2 – Passenger is pretty much dead on the CofG so doesn’t majorly affect the balance point.

Dashboards and struts and footrests

Finally got a browser that works ! Firefox …

Dashboards have been worked on and are both now fully covered in the green leather i got. Holes have been re-opened and now starting the wiring up process. Lots of handshake fly leads to connect up.

The fuel sender has come straight back from the guys in Norfolk from repair so ready to calibrate

 

Been a very very busy few weeks …but ..managed to keep moving on ..

With work going crazy and flights tobe made toLuxembourg (a very very long runway of 4k+ !) and last weekend Paris/Toussus .. I have finally managed to get back to some work on the Sherwood.   I have made so many lists of things that need to be finished off … so this session has been lots of those … struts covering (decided Olive Green would contrast the predominance of cub yellow  !) … electrics cabling from battery through the bulkhead to the solenoid …   Brake turnbuckles…. re doing some top covering (more on that later) …   Also, post the LAA recent article ..a full re check of my 12 wheel nuts for tightness ….
