you can try me on 07917432041 for this coming weekend. I operate a Jabiru out of a farm strip near Leatherhead in Surrey..weather is currently not so good but there's always a chance for a pint... Keith...

If you check out AFORs UK you will see Savannahs have been selling at around the £17000-22000 mark. So I would say that is a fair price. Are you planning to leave it on floats...?

AGM batteries need a minimum of 14.5volts to charge to a 100%. Ordinary battery chargers only give out about 13.8 volts which will charge an AGM to about 85%. A lower battery voltage means less RPM from the starter ...less RPM means a smaller spark .. smaller spark means no start. At 85% charge the AGM battery voltage sags very quickly to 11.2 volts and then recovers ...if you don't get a quick start the battery goes flat very quickly. I recommend the CTEK 5.0 amp battery charger with AGM recondition and normal charge mode. My Jab 2200 starts first time every time even at temperatures below freezing.. hope this information is useful...

this is a fake video ...the undercarriage cannot be raised while the aircraft is on the ground due WOW factor...

20 hours and still no solo ? ..... seek a new instructor or a different flying school... on average most students solo between 8 and 12 hours.

In preparation for the Queens funeral there have been notams re GPS jamming and no fly zones centred around Buckingham Palace for a radius of around 10 miles. I put a clip of the Notam from Skydemon.

My comment mentioned the % ingredients expelled in the exhaust emissions, not the in the combustion process. Gases / fluids coming out of the exhaust is about 10-15% water and approximately the same % in CO2. The rest of the gas is N2. You are correct in the Atomic weight calculations. Without going through complex calculations and dependent on the humidity 1 gallon of petrol will produce approximately 1 gallon of H20 when burnt in an internal combustion engine. That is why we see water coming out of the exhaust pipe of our cars.. more so on humid days. As with any motor it is the water or condensates that remain behind in the crankcase that will emulsify into the oil. This water + oxygen is main contributor to corrosion in any internal combustion motor if left extended periods of time.

The emissions of petrol driven internal combustion produces about 15% of H20. If the engine oil does not reach optimum temperature the oil emusifies in the oil and can cause internal corrosion surprisingly quickly. Modern multigrade engine oils with additives can minimise the effects. But I follow the general rule of an oil and filter change every 20 hours or 6 month whichever comes sooner.. Also if I know the aircraft is not going to fly for a while I run the carburettor dry turn the prop over a dozen or so times and then park it. before the next flight I would turn the prop over a dozen times or so, fuel cock open ,fuel pump 10 seconds, full choke, throttle completely closed. The motor fires up instantly....every time...

Videod this last weekend at a place called Barton Ashes NW of Winchester... was a bit concerned as the wind from the left was curling over the trees and not helping the lift off... https://photos.app.goo.gl/KdRpmkMiaScqwB9w7

Nice one...

Don't think its El Nino.... but right now in the UK and, as far as I know, in Spain and France, there have been a spate of thunderstorms and flash flooding. Farmers are happy...

good stuff there Bruce .... you might like this article re soaring the Appalachians... Four on the Floor.pdf

Not really interested in copy and paste YT videos......

Adding my own experience on Skyecho2. 1) The GPS engine is not the best . Frequent drop out while the Huawei cellphone stays locked on. 2) SE recommend it be mounted facing forward and upright. This means it will only transmit and receive in a roughly semicircular arc from SE forward. 3) This was confirmed by Farnborough radar when I asked if they could see my conspicuity squawk 7000 while I circled over my home strip. Primary radar showed a continuous return but SE 7000 transmit dropped out when the Jab was facing away from Farnborough. My thoughts are when two aircraft are equipped with fully operational SE , if one aircraft is coming up directly behind another neither will see each other on SE. 4) A USB charger on the aircraft will only slow down the rate of discharge. 5) You set the aircraft stall speed...SE only becomes active when the aircraft has a groundspeed greater then the stall speed....but I think that 7000 continuously transmits even while stationery on the ground. 6) Flying in my area I have only seen one aircraft tracking in the opposite direction well away from my track. SE say that the algorithm will only give a warning when two aircraft are quite close together and that if continuing on the same tracks a collision may occur. I still do not know if SE determines the difference in height. 7) Still worth picking one up with the rebate scheme. Will write more of my experience in the month to come... cheers from the UK officially in drought condition....
