    Nice one Geoff, see you there!

    What 'weight' is it? Summer or winter weight?
  3. A few of us Bailey owners use an additive to the fuel - Classic Valvemaster Plus, doesn't cost a lot as you don't need much per litre. https://www.demon-tweeks.com/castrol-valvemaster-plus-lead-replacement-with-octane-booster-cas1770/?istCompanyId=a2904180-3a7d-4e56-b876-cf81c9512180&istItemId=-xpitwalqqa&istBid=t&gclid=EAIaIQobChMIzc3wu__O4QIVYrXtCh07KQu2EAQYASABEgKCqfD_BwE&gclsrc=aw.ds

    Looking to buy a used motor and wing

    OK you lovebirds, where abouts are you and what is your budget? If your weights differ a lot you will need two sizes of wing.

    Can I fly in or near this chevroned corridor?

    Not much but it is very easy to fly through your own wake. Just make a tight turn and there it is, just gives you a wobble or little bump. Yes it is fun, that's why we do it 😁

    Is it cool to fly over an ATZ (class G)?

    My take off field is only just outside an ATZ so I always contact ATC once airbourne and confirm I am remaining clear of the ATZ.

    Thanks for posting this David, saves me from trying to. Good to spell it out to those that want to know. Alan G6WJJ

    Lets see if we can lower the flypast 😁 SafetyCom and the microlight channel are completely separate. I was just indicating that the reference for both channels has changed, even though the actual frequency used has remained the same. I knew the way the 8.33 channels are referenced would cause some confusion. To re-state the situation: In order to differentiate an 8.33 channel from a 25kHz channel the 8.33 channels are now referenced by a description involving steps of 5kHz (in verbal communication and on the display). The 'actual' frequency used may not have changed, particularly if it was already on a 25kHz allocation. Techie bit - ignore if this continues the flypast. The necessity to differentiate between the old 25kHz regime and the new 8.33kHz regime is to reduce interference from old 25kHz equipment (remembering that Air band is worldwide) when used within the 8.33 areas. A legacy 25kHz transmission is wider than the new 8.33 and can bleed into an adjacent new 8.33 channel. Hope this is clearer.

    No just the channel reference has changed. Transmit/receive is still on 129.825MHz. It just indicates you are in an 8.33 environment. The Safetycom ref 135.480 is still transmitting/receiving at 135.475MHz. A little confusing if you think of the 'real' frequencies, but indicating the 8.33 use.

    Yes I agree, confused me to start with until I thought about the legacy implications.

    Hi David, There are no anomalies of the 'actual' frequencies used. The legacy channel width of 25kHz has been split into 3 equal parts to provide extra channels. Frankly this surprised me as I was expecting it to be slit into 2 as other bands were some while ago, giving a 12.5kHz channel width. So the frequencies used are, for instance; 123.000, 123.0083, 123.0166, 123.025, 123.0333, 123.0416, 123.050 etc. Personally I was expecting to see .008/.016/.025/.033/.042 etc. on the radio display but the powers that be decided to refer to the channels by the nearest 5kHz. My guess is that was done to accomodate existing displays (possibly that can only display a 5 or 0 at the end, remembering that these allocations are decades old), plus a simpler software re-write for display duties. The new channels are thus referenced by the nearest 5kHz (a bit crackers IMO). So the radio will display frequencies in 5kHz 'slots' on the display but the actual frequencies will be on 8.333kHz increments. Display = Frequency as so: 123.005 = 123.000 MHz Channel 'Zero, Zero, Five' 123.010 = 123.0083 MHz Channel 'Zero, One, Zero' 123.015 = 123.0166 MHz Channel 'Zero, One, Five' 123.020 = 123.0166 as above. 123.025 = 123.025 MHz Channel 'Zero, Two, Five' 123.030 = 123.025 as above. 123.035 = 123.0333 MHz Channel 'Zero, Tree, Five' I hope this explains the apparent anomalies.

    Ok here goes...!

    Ooooohh bugger. You don't do things by half do you Andy. I'm sure everyone on here wishes you a speedy and complete recovery. Hope to see you flying soon at a PMC fly-in.

    Using rubber on propeller hubs

    It's a rubber washer that covers the whole boss mounting either side of the propeller. Never had any problems with it.

    Well done Mark, yes there is a lot to learn but well worth it IMO.

    Thanks Simon, I will update the memory in my radio. Checked the radio and the frequency is the same 135.475, so why does it need to be referred to as 135.480? Nuts.
