Spring is here again - who's been flying?
Shaun Walsh replied to GrumpyGnome's topic in Flying Field Reports and Chat
Need one of these. -
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.

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.

If that was the case all home brewers would be blind or dead!

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 🙏

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.

Laser engines - the state of play following their closure
Shaun Walsh replied to Ron Gray's topic in IC Engines
I dare say that Progress Aero Works in Macclesfield could do it if they had the time and inclination. -
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.
