I use LiFe. Both chemistries are bulletproof, but LiFe can be charged really quick if you want a surprise model, or a surprise session, as in 20 minutes and out the door. If you want more load capacity, use a bigger LiFe pack.
Note NiMh to me equals Enloop cells. The rest I have concluded over the last couple of decades are rubbish.

I’m a bit reluctant to pick over a carcass. But Laser have always been about £100 quid or so too cheap at retail. So me being tight, can acquire a second hand motor good for a thousand hours, hardly run, tough, for peanuts. Name me a reason, why should I pay a lot more for a Japanese motor, and buy flimsy.
Why not sell the company, the tooling is the company, and they have nice tooling. -
Can’t the design, bubble or razorback be the same kit. When Topflite did them, the razor back to bubble conversion was only a minor modification kit

Like this thread, I’m in the same boat, 11 year old Dx9, flawless service.

Not sure about the science of some of that, but hey ho.
Standing outside on a breezy day, upwind of the jar, heat it with a blowtorch. Don’t melt the glass. Take care not to burn fingers.

But you still get long chain molecules in a 2 pack. Solvents pick at the end. Heat the things to shorten the chains, more ends to pick at.
Non technical, but you see the shape of the argument?
-
For 2 pack, I would, when the wife is out, put the jar in an oven going flat out. Hot enough for the chain molecules to start breaking down, and give your solvent a key to do its work.

I tried the last, last week. Well dry for a long time, and very hard work.

I would not mess about with much theory. Assemble it, use a cg calculator, balance it and go fly.
I’v done a few Frankensteins over the years and no huge surprises.-

If you have ever had the pleasure of wandering the streets of a night club area at 4 in the morning, watching the rats and gulls sorting the streets out, makes you realise the reluctance to actually pay people.

After you for the first million flights.

No mate. They are hewn by hand, from seasioned oak, by the coach, using worn out sandpaper, only lubricated by his tears of sorrow.

Mid airs, if had two, both times 2 aircraft up.
1. Bloke spun down from high, I wandered under him.
2. Bloke pulled humoungous loop, and took the tail off mine at the end of it, as I innocently wandered along. That one was slightly funny, the tail stayed on long enough to start turning to land. Then it fell off.
Both times agreed anticlock circuits. -
I’d say then, unless you wish to endlessly crash, repair, replace, join a club for a bit, learn on a buddy lead. The muscle memories don’t come as quickly as we age. Getting the thing off the ground is easy. Putting it down again, in oneish piece isn’t so easy.
Then you then wish to go it alone, your choise.
-
Before we start arguing, Enquisiter, welcome.
What’s the aircraft? And can you fly it, any experience, past or current? And how old are you -

Regular eye tests........very important even if you don't need distance glasses. As one gets older visual acuity does decrease especially with the onset of cataract that creeps up so slowly that one doesn't notice. Years of staring at flying models in bright sunshine without proper UV protection or just being an 'outdoor person' for large amounts of your time does give your eyes a good dose of UV over time and can promote cataracts so my optometrist tells me. Certain medication (steroids) have a similar affect, apparently.
Ten years ago I was told that I have very slight signs of catracts in both eyes although I never noticed any problem with my sight - I have bi-annual eye checks, take care to protect my eyes in bright conditions and there has been no further deterioration
Also give the eye checker a stress test, age related paternalism is common. I’ve had the comment frequently, “but you have very good vision, Mr Fry (sometimes even with “for your age”). A simple statement “my eyes are better than that”, perhaps repeated, gets better vision. Sad but true. Remember, stuff like flying, shooting, trains your systems, and you know what you can see, with the correct lens in front of the eye.

Look on the bright side Jon, bet you are in for less hassle. I have had a cogitate and I reckon, I am engined for life so I will survive..

Or more to the point, how many machine gun bullets do you need when the population of Bangladesh up sticks, and go somewhere else. Or how hard do you fight, when the next country upriver decide to increase extraction in a drought, and your water supply disappears.

Personally, I would wait for Jon to confirm.

Look on E bay, Chinese sites. Couple of quid gets you an 0.1 gram, max 500g electric balance. Then you can weigh stuff accurately.
There is a law of chemistry, the rate a reaction proceeds doubles for every 10°C rise in temperature -
I bought a kit. Accurate description, well packed. I would use them again.

Or a Laser 100 if you want more torque to up a heavier airframe.
