Going to be a bit like the same question about car's. Ask a dozen people and get a dozen different answers I recon. Veteran, Edwardian, Vintage are pretty well defined but when it comes to classic ??????

Keep going Matty

Many flying boats had issues with handling on the water, after all what you have is a boat with a horizontal sail on top which wind can effect. Multi engine types had an advantage of being able to vairy throttle settings to go where they wanted. It was often the case with full size prototypes that despite the designer's best efforts testing would show the need to change the position/shape of the step. Another issue for models is that water molecules [ and air] are still full size.

This thread was about glow fuel price, nothing to do about petrol.

First time out for me this year having recovered from Covid, long cold and injury [ got kicked by a beef steer] Was good to meet up with the chaps on the field and get some flying in over the weekend. Members been erecting new safety fence.

I run several old OS MAX engines, couple of 15's a 20 a 40 and an LA 40. All are happy on the fuel Jon suggests above. In fact all my other makes including 4 strokes run on it with one exception my Cox TD051 it likes the hot stuff.

That's a fine pilot, looks ready for action.

Another way of keeping a low use car, boat, tractor battery topped up is a solar trickle charger. Can be clipped direct to batt or fed in via power socket.

There are as many stories [ old wife's tales] about car and other vehicle battery's as there are about nicads, nimh, and lipo's. Many on line of how to revive dead ones, just don't, they do not work and some are dangerous. Last year I was on my way to the flying field when the battery warning light came on in my cars dash. Shortly after the power steering shut down and then engine went into limp mode but still ran. Tests showed the battery was low volts. Turned out alternator had quit Now in an older vehicle once the alternator stops working the charge warning light came on and gave plenty of warning for you that it would sometime ahead run out of charge. In more recent cars the batt warning light controlled by the ecu only comes on when the volts get low giving little warning. I now have a volt meter that plugs into the car power socket and can keep an eye on state of charge in the battery [engine off] and if charging [engine on].

As a farmer's son we used to have a neighbour somewhat like the chap in @Cuban8 above. You would meet him one day and he would be as nice as pie, and another the grumpiest of grumpy gits. He was a serious diabetic and back then controlling the effects were more basic and did not fit well with the every day work of a farmer. Things came to something of a head when he assaulted a feed rep who called at the wrong time!

A bit like myself out on the farm in recent day's, Layers of clothing against the cold topped of with waterproofs. Need to open a bale of hay and penknife in trouser pocket. Grrr.

Well 842g is pretty close to JL'S list above with 835g for the 150 of that generation. Do not expect the measure to be exact, manufacturing variance and your bit of rubber would make that up.

Good one Paul, more for the older models, even the weights are in ounces. John.

Very much doubt if any of the above is possible. Here is my take on the issue of a way to identify Laser engine size. This applies to The later models with the vertical glow plug hole. It goes on number of barrel cooling fins and weight of unit including muffler. 70 8 fins 580g 80 8 fins 690g 100 12 fins 810g 155 13 fins 955g 180 14 fins 1240g Previous models like my 150 has 12 fins and is 920g Another feature of post 2000 units is two screws holding the valve cover on but not sure when this change came about. I think the above engine is a 150 from the 90's if close to mines weight.
