Radio 4 'long wave' moved from 200kHz to 198kHz several years ago to comply with 9kHz channel spacing.

My solution to the 'undercarriage' problem with Wot4s and Acrowots was to tap out the screw holes (think it was M4) and fit cheese head nylon bolts instead of the steel screws. I occasionaly sheared the bolts on heavy landings, but never ripped ot the plastic fixing plate. My last Wot4 survived over 200 flights before I passed it on to another club member.

If you are going to use the drill/measure AC voltage method, you need to multiply the rms voltage by 1.414 to obtain the peak voltage. Some folks also advocate multiplying the peak voltage by 0.95 to approximate the motor's efficiancy.

Foam-Tac is good for depron, can even be used a hinges in place of Blenderm tape etc.

I see there is a 6 second jump in time between 34:24 and 40:00 seconds - an interuption in battery voltage to the transmitter?

One method is to flood the joint(s) with low-melting point solder (typically 145 dec C) You then have time to remove the component before the joints solidify at a temperature that does not damage the PCB or component. Remove the excess solder with solder wick before fitting the new component with normal solder. ChipQuik do full kits (expensive) but you can buy the solder by the metre (try here)

Hi Brian - see my PM

If you watch the beginning of the video from the Pheonix 1600 link, you can see that the model's battery connector is an XT60 (and that the owner is using an XT60 to Deans adaptor to suit the battery he is using)

+ 1 for the Epson inktanks from me as well. Mine is of similar age and the very frugal ink consumption will more that pay for the higher initial outlay.

Hi Erfolg, If you google 'epson stylus sx425w printer error e-01' you will find several suggestions as to the problem - best of luck. Sparks

Just for info, the brackets of a switch description indicate the momentry positions ie (ON)-OFF-(ON) is a center-biased three position switch. ON-OFF-ON is a three position switch with no bias.

Thanks for the prompt replies folks. Macc Models seems the best option as they stock the sizes I need and prices are reasonable. Richard

Hi, can anyone suggest a supplier for brass tubing and rod, specifically 10mm O/D and 6mm O/D brass tube or rod? I've looked on ebay, but most suppliers seem to be in the far east. Thanks, Sparks

I have had several deliveries of PCB's (printed circuit boards) from China via FedEx and they have all arrived promptly. Generally leaving China mainland on Monday/Tuesday and being delivered on Friday morning the same week. Just saying....

These steering modes are refered to as 'Crescent' and 'Star' steer. With Crescent steer, the vehicle will retrace its forward path in reverse. So, if you run the vehicle repeatedly forward and backwards the steering path will be crescent shaped (like a car). With Star steer, the steering direction is reversed when going backwards. So, if you run the vehicle repeatedly forward and backwards the steering path will be star shaped.
