|Thread: 2 vintage engines, what makes please?|
As others have said, the engine with the cropped prop is a Bunch Mighty Midget dating from around 1938 and designed by Dan Bunch in the USA. The other engine is a complete mystery to me, I suspect it is home made possibly from a published design and probably British.
I've been collecting sparkies for a long time and a few of my collection can be seen on my website:
Your Bunch is among those illustrated.
|Thread: Veron Avro 504N|
Very nice job, looking forward to your reports on the maiden. I'm sure it will fly well
|Thread: The RCM&E 60th Anniv' Fly-in ** CANCELLED **|
The scary thing regarding 60 years of RCM&E for me is that I bought the first issue (which I still have), mind you I was a schoolboy at the time.
|Thread: R/c flying on Country file|
I finally got around to watching this, best advert for model flying I've seen on TV, far better than the Battle of Britain program reenactment using models (Channel 4?). Well done to all concerned.
|Thread: Veron Avro 504N|
Nice job with the dummy engine
|Thread: Trendsetters and Iconic Models over the Years?|
+1 for the Taurus, my first low model and a delight to fly. They were the dominant multi aerobatic model back in the mid 60's.
|Thread: C.A.A Reg number ,inside or outside ????|
Thanks for the alert, I've just ordered one plus some labels online
|Thread: Your experience of Banggood delivery time?|
I've never had an order fail to arrive although a few orders have taken ages. Biggest problem I have had is with their terrible packing, fragile items arriving with a bit of thin bubble wrap around the item and put in a plastic bag.
|Thread: Buying LiPo`s|
I have always bought them from the UK warehouse
I've had consistently good results from the Hobbyking standard Turnigy LiPo's
|Thread: Full size aircraft displays|
Best Eurofighter Typhoon display I have seen. The pilot is a real showman
|Thread: How many flyable aircraft do you have ?|
A quick count reveals 11 fixed wing and 2 helicopters plus 0 drones. All are electric
|Thread: Motocalc or Ecalc?|
I've been using Drivecalc for several years and have found it gives a pretty good idea of what to expect from a given motor/battery/prop/ESC combination.
|Thread: Charging Lipo batteries|
As the Halfords PSU is a switching regulator it should have a fairly smooth output and is likely to be OK. Laptop power supplies are also switching regulators and should be fine. The old train transformer probably has an unsmoothed output and I would not risk it. The only way to tell for sure is to look at the output with an oscilloscope and see if it is a fairly smooth voltage or a series of humps at 50Hz or 100Hz. I think you should be OK with the Halfords unit.
You need to make sure that the output from a train transformer or similar device is smoothed (typically with an electrolytic capacitor) and not just half or full wave rectified unsmoothed DC. The charger will not work properly and might be damaged by an unsmoothed power source.
|Thread: ESC only works when increasing the throttle very slowly|
I've had this sort of issue several times in the past and it has nearly always been timing or start up mode related. As has been suggested try the low timing setting and also try changing to a softer start up mode (but only change one parameter at a time)
|Thread: Suggestions for vintage model|
How about a "Sparky" designed by Harry Hundleby. My original back in the day was single channel, I made another some 10 years or so ago with rudder and elevator. A tough model and amazingly aerobatic, suits 1.5cc diesel or as in my case electric power. Plan is on Outerzone.
|Thread: Now That Is Proper Modelling...|
|Thread: Another Millennium Bug?|
Oops, finger fumble. It might turn out to be a big bug though!
I'm surprised that the GPS WNRO (week number roll over) has not received more publicity. The 10 bit week number count means that every 19.7 years it starts again at zero and this happens next on April 6/7 2019. This can (and will!) affect older GPS units not designed to accommodate this. Time and date information displayed could become erroneous. You can read more about it here:-
I had an email from Tom Tom regarding my old GPS to inform me that it is not compliant and they are not going to update it but will give me a 30% discount on a new one (I don't use it anymore so not a problem). My smartphone got a system update yesterday to deal with the problem even though it is only two years old.
I suspect a great many people worldwide are going to wonder what has happened to their Satnavs, smartphones etc in a day or two's time.
