You know what it's like when you get a new module to program , at first it won't compile because the libraries are incorrect ( hours wasted ) then it won't upload . More time wasted until someone on the Internet mentions you have to push the boot switch while connecting ! Knowing that would have saved me hours but its tinkering in something new so hey-ho . ESP32_C3 getting to like the the finicky little devil now I know how to talk to it .

I've got around it my address was incomplete on AliExpress, until it's has complete data not just postcode it gives error " cannot ship to country" .

Just getting round to populating the Flyinflynn boards and am finding the GPS module a bit hard to find , HT1818Z3G5L in UK . AliExpress has them but will not ship to UK according to website . Anyone got a contact for them I don't want to bodge another unit in unless I have to.

FlyinFinn I've played with the XIAO but not familiar with the others . If you have any spare boards I'll gladly pay costs ( the bin is getting full ) plus postage . Cheers

FlyinFlynn if you are UK based would you be interested in selling some pcb boards to offset your costs ? I'm a complete numpty when it comes getting circuit boards done , last lot I ordered ended in the bin.

Thanks everyone something to get me interested putting the E back into RCME . I copied completely a GPS/Arduino data logger with SD card from the internet and made a couple for lads at my club with just a few alterations to the code to display speed etc . The format of the output isn't right to display on Google but I will have a look at the code above and see if I can work it out . I've got an homemade Arduino Frsky GPS logger I got that to display in the Frsky suite the location and height data. The SD card version just displays location,height,speed and time which is all the CAA want for +25Kg models I think . Nice to know someone else is tinkering and getting results .

Still slow 5 minutes this Sunday before it let me in !

I've still got a works issued Fluke with a calibration sticker dated around late 90s which works fine except the case is araldited together and has tape around the case ( hard life) .

Could be Mr Putin , funny how you forget one war when another kicks off ( Gaza).

Maybe the CO will rotate to a new posting next year ?

I've noticed that not many fliers have the old Nimh tester that puts a load on and displays on leds - good or bad. I rummaged around and used a cheap voltage display ( 3-30+ volts) and a switch that puts a 20ohm load across the battery . This gives a current of about 300mA on 6v and 250mAh on 4.8v a good load . What would you think an acceptable voltage drop at that current draw should be ? I was thinking no more than 0.2 to 0.3 volt drop on a fully charged battery , anyone else got any thoughts ?

Another for the Cox Stuka control liner when I was 12 about 1970 , should really have had a helper to fly as the inevitable happened and it didn't survive .

Does anyone know for sure I'd the Tundra wing struts are structural , the wing is pretty stiff without ? The reason my friend dumped one in a tree yesterday we got it back but the strut has torn a hole in the wing where the fastening used to be . Anyone used one without ? It's 2nd hand and little tatty so no great loss if it claps ! That's the smaller Tundra not the Grand Tundra .

Little more specific but the Amateur Radio courses run by clubs would be a good start , there are 3 levels and give a good grounding in electronics . Plenty of clubs running the courses and providing help . My personal introduction no longer exists 3 years of Nautical College leading to Radio Officers ticket , very in depth course but things have moved on since the 70s.

Has anyone got a figure for a DLE20cc on a Menz 17x8 wooden prop , I'm getting 7000rpm is this about right ?
