Re: OFCOM Change Of Licence Requirement

I had the same email. Nothing to worry about as far as I can see. My transponder is also about 200W, but only draws 1/3 A, so 4W of power consumption. That's for transmitter, receiver and display; so the radiated EMF must be less than 4W average. If there were any risk of microwaving your bodily org...

Re: The perfect Aeroplane......

In the homebuilt list that Ian mentions, half of them are biplanes so don't meet your criteria. That leaves RV-4, 6,7, 8 (and now 14) plus the Falco, CR100 and Sirocco. Those last three are very few in number. The RV4 and 6 are lighter that the 7 and 8 so better suited to shorter runways although th...

Re: Use of Stainless Steel AN bolts in place of CAD plated AN bolts

With Titanium/stainless the stainless will become the galvanic anode and subject to corrosion, the Titanium will be the cathode and not at risk, so you would still need a galvanic barrier.
I believe that they both meet the strength requirement of AN bolts, so that should not be an issue.

Re: Use of Stainless Steel AN bolts in place of CAD plated AN bolts

Stainless bolts are more prone to galvanic corrosion in contact with aluminium than Cadmium plated ones.
The bolts won't corrode but the adjoining metalwork is at risk unless a suitable galvanic barrier is used.

Re: 0.125 2024-T3 off cuts

Give LAS a call. They may have off cuts.
They'll also supply items from the Aircraft Spruce catalogue.

This may be an option

If it's Poly-tack or similar, then MEK is the solvent (and gloves and a respirator!)

Re: Hangarage Immediately Available on a Grass Strip

I'd suggest that the description perfectly describes the strip on the southern edge of Santa Pod raceway.

Re: Export Certificate of Airworthiness

The situation may be different depending whether the aircraft is amateur built or an orphaned factory built aircraft that has been granted a permit to fly. Amateur built aircraft don't have a type certificate data sheet (TCDS), so there is no way that they can obtain an export CofA. There are some p...

Re: Export Certificate of Airworthiness

An export CofA can only be given to an aircraft with a standard CofA. It merely certifies that the aircraft conforms to the type certificate data. I believe homebuilts in Sweden use a system similar to the FAA. I know that many homebuilt aircraft have been imported into Sweden. I would guess it invo...

Re: Compass Repair Kits

The compass fluid is treated as dangerous goods which probably accounts for the high import cost (oddly a compass containing the fluid is OK). The fluid is quite similar to white spirit, which should work OK, but is a bit less viscous. It's a good idea to replace the diaphragm when servicing the com...

I have the Aveo lights on my Carbon Cub as in this video.

Very bright, easy to install, no radio noise. Not cheap, but they work very well.

Re: Kitfox Tyres

A suggestion.

Find the aircraft spruce part number from their online catalogue.

Go to the LAS web site and search for that part number.

LAS are agents for Aircraft Spruce and have regular shipments.
