A wall or trees on the flight line is like a lake in front of the tee to a golfer, they all instantly attract the object that is trying to avoid them!
One of the sites I fly at has trees on two sides, the clubhouse on the third (no overflying) and a 6 foot bank surmounted with a 3 foot palisade fence model chipper on the fourth. Landings can be like a dambusters raid.

Have a look through the reviews here:
https://hobbyking.com/en_us/volantex-742-7-phoenix-1600-epo-composite-r-c-glider-pnf.html
A number of complaints about motors burning out but in some cases it's not clear whether they were using a 2S or 3S battery. Given the motor is 1400 KV the prop fitted may be too big for a 3 S battery causing the overheating problem.
There is one comment about moving the CG 8mm rearward and it flying OK. -

Two spelling mistakes in one word???!!!. Obviously whoever dreamed up that notice qualified to use the lift.
The question is:
Is it a lift for disabled people to use .... or
Has the lift been disabled by turning off the power or
Has the lift for disabled people to use been disabled by turning off the power?
Also, is the word "diabled" simply a disabled version of the word "disabled"? -

In a recent TV cookery program it was said that 80 percent home made alcohol was/is methanol ?
Takes lots of sugar to make it I was told, gives me a headache, absorbs moisture like billyo and by God the best cleaner/degreaser I have used apart from carbontet .
I treat the stuff with very real caution !
Still not plucked up enough courage to put some in the moped ! 🤓
If that was the case all home brewers would be blind or dead!

Suprisingly I knew that. It’s an old fridge that is both light proof and heat / cold proof and unused. It stands there as a store cupboard and the fuel fit fits in nicely. I also store the few Lipos I have in special Bat Safe boxes. I keep the risks low.
Some leccy fliers I know have large puffed up batteries that I would not give house (or garage) room.Excellent. I check the internal resistance of my lipos regularly and if it rises to high or too quickly or if they are badly unbalanced they get fully discharged and disposed of. They live in liposafe bags in a 50 calibre ammunition case with a big bag of cat litter on top. The hope is that if they do catch fire the cat litter bag burns releasing the mineral cat litter to slow the spread of the flames. Hope I never find out if it works 🙏

It’s sad to think IC is disappearing I think the IC engines still have a great deal going for them and a lot more character. Learning to manage them is something to be learnt -yes- but electrics leave me confused and Lipo’s are a potential disaster if mishandled and can explode in the extreme. I looked at the cost of converting one of my IC models to electric and the cost was alarming. The cost of batteries is significant to the extent that the project has been shelved. Let alone having additional batteries in the garage. Fortunately I have plenty of engines still in stock. I have enough fuel to last me and it is stable in the fridge. A big argument against IC is the noise but a good silencer solves that and I have the silencers to cope with all my engines. Seems that most model shows and many clubs have users of large petrol engine some of which are both large and quite loud, but these seem to be quite acceptable.
Hope the fridge isn't turned on. Flammable liquids stored in the fridge are a serious explosion risk, a loose cap or slight leak can lead to a build up of flammable vapour which a spark from the thermostat switch can ignite.
The lab I worked in had a special fridge for storing flammable liquids which had all the electrical equipment on the outside of the fridge isolated from the interior.

Tell the local paper reporter that It fell out of the sky when a Boeing went past, and you will get all the papers posting it on the front page, the TV will all jump on the bandwagon stating 350 lives at risqué of crashing, in a town etc, and of course the Police.

They were beaten at their own game by Far Eastern products that were / are arguably better than their own (with the exception of 'tex and Clear Coat). Regarding taking it on, I did enquire about the rights to produce Clear Coat but was told that I couldn't afford it!
Not necessarily, the sub 50cc market wants 4 strokes due to noise restraints and Laser offered an excellent range to suit that (dwindling) market and as for mess, what mess, the latest Laser engines running low oil produce no more mess than a petrol jobbie.
Various options here, as a cottage industry you would seek out precision engineering companies who would produce parts in their 'down time' so it would be a limited supply but still a supply. Alternatively, there are precision engineering companies in India who could produce small runs of the parts. The assembly of the parts would then be done here, in the UK by a one man band type setup. Over simplifying I know but..........
I dare say that Progress Aero Works in Macclesfield could do it if they had the time and inclination.

Could anyone suggest the type of battery tester I would need to get please
You will also need a watt meter to check the current draw if you experiment with different prop sizes.

According to propCalc, you should get 10 to 12 minutes of mixed flying but you should fly for a few minutes, land and check the battery for a more accurate estimate.
Also, that set up appears to produce about 30 to 40 watts of power which isn't much for the size and weight of model. A 10 by 5 might be better but you would need to check the current with a wattmeter, also it would reduce the flight time to 8 to 10 minutes.

Hi I will be flying my 48" ben buckle diamond demon weight around 1.5 lbs using a overlander 2826/18 1000kv v3 motor, a 1300mAh 2s 7.4v lipo battery pack, 2 mini servos. I probably will fly for around 4 minutes at a time, how much battery life/duration should I expected, is there a rule of thumb guide for electric flying. Cheers in advance.
Prop size?

Many thanks that's it exactly. I found them on the Polish Amazon site but not in UK. It is indeed from a big RC vehicle
I just downloaded the image you posted and used Google Lens to find matches.

Hello everyone. I am building a Belair Nieuport 11 24" kit and bought the recommended motor which has a 1.5mm shaft. Recommended Prop is a 7x4 which I bought the master airscrews electric only prop. For the life of me I cant find an adaptor that goes down to 1.5mm motor shaft the ones that came with the prop are too big. Any advice or links welcome
thanks Craig
If you just google 1.5mm prop adapter there are a number of options available.

I have bent the shaft in the supplied motor of my acrowot foame, but can't get the grub screw out to replace the shaft. Alan key just too small and not strong enough. Anybody have a hack for removing the grub screw.
If this fails I have a 1050Kv motor (supplied motor 820Kv). Will this work or will I lose power.
Neil
Can you provide more details on the 1050KV motor? You won't necessarily lose power but it may need a slightly smaller prop to avoid exceeding the current rating of the ESC.

Thanks Chris. Point taken and I agree totally. It is a rudder servo that is oscillating rather than rotating. Probably OK to fly but I replace rather than put the plane or people at risk. I find it needs rudder to do good turns (drags it’s tail in turns) and of course it takes a beating on the ground.
S
I had a similar problem on my Slowpoke, gears on the rudder servo stripped eventually due to the extra stresses imposed by the tailwheel. Replaced it with a metal geared one.

Hi I have recently returned to this hobby after many years away, and I look forward to getting new ideas and approaches to building and flying model aircraft again
I returned after nearly 45 years and found a completely different world!🤣

I looked up the transmitter on the hobbyking website and the battery looks like a repurposed compact digital camera battery. It may be possible to find a replacement by sending dimensions and pictures to a camera battery supplier.
Whether the tx is worth buying depends upon the price but it would have to be very cheap to be of interest.

An HB3 headlight bulb will connect directly to an xt60 connector, just have to trim the plastic on the bulb and bend the bulb connections slightly.
