Re: Ken Bones 55

Sheila and I have known Ken from when he was a very young man and first started flying at shows. We were operating TX control in those days at nearly all of the LMA events and Ken used to come to us for a chat as he didn't know many flyers at the time. Ken was one of the nicest blokes you would ever...

Re: Setups without SM Services units!

Hi John, I'm not sure which David you are replying to. My profession for almost 50 years has been as an electronics engineer and believe me I have had to replace hundreds, if not thousands of failed silicon diodes in equipment ranging from high power stage amplifiers to transmitting equipment, telev...

Re: Setups without SM Services units!

For additional safety, without compromising electronic fallibility, fit one of my Engine Failsafe units. This will, at least, stop your petrol engine in the event of complete battery failure and prevent the model hitting the ground at full throttle or watching it disappear into the blue yonder. The ...

Re: LiPo danger

Just as an aside to our modelling experiences.If you remember a while back Boeing 787's were grounded for 6 months because of the fires occurring in the lipo packs used to start the APU at the back of the aircraft. I don't know how they were charged but it was interesting to hear that the factory ma...

Re: Dave Tappin

I've known Dave for more years than I care to remember. I was involved in a show with him at Ripley Castle a long time ago and he suggested we meet in Betty's Cafe in Harrogate. I was looking for something like a transport cafe but was amazed that Betty's was like something out of a 1930's movie, ve...

Re: LiPo danger

Hi Gordon, in reply as to whether I was using balanced charging I have a couple of chargers but one is without balance leads. This time the balanced charger was in use on another battery so I was charging the 'firework' battery directly. I must point out hat this charger has been used countless time...

LiPo danger

The warning 'Don't leave LiPo's charging unattended' is not without substance. The battery in the pics was on charge in my workshop using the same LiPo charger that I have been using for years and the battery had been charged many times. I happened to pick it up to move it to one side and noticed it...

Re: Quadcopters

There was an item on our area news a few months ago about a small quad being flown in someones garden, the unprotected blades caught a small child in the face and seriously cut one eye. The damaged eye could not be repaired so that child will spend the rest of its life blind in one eye. Nothing was ...

Quadcopters

Paid a visit to my local Maplin store recently and noticed a large poster explaining the rules on flying quads and model aircraft bought as 'toys'. I'm just wondering how many people will really take any notice ?????

Re: Workshop heating

Just a warning about using free standing calor heaters. A few years ago I was spending quite long hours in my small workshop/office due to a contract with a deadline on it. I was using a calor heater without efficient ventilation, I know, my fault! but it was winter. After a couple of weeks I was fe...

Re: Workshop heating

If you can get a cheap or free supply of logs or any wood, try a log burner. Works in our large workshop. Just make sure it is away from anything that doesn't like heat and that it is totally closed up when you leave the workshop.

Hooray !!! Congratulations Dave on getting a bit of recognition for us on the One Show.

Well done, I hope the coverage gets a...

Additional engine failsafe

I have sold quite a few Failsafe units due to my article in the last Journal by people paying by cheque but I realise that in this modern world not everyone has a cheque book. If you would care to purchase one of these units I can arrange a Paypal invoice. Just contact me by Private message with det...

Use of our website

The LMA website does not seem to be getting the usage that other association sites attract considering the hundreds of members in the association. Not many discussions about the hobby, the equipment we use, experiences we come up with etc. etc. I go on to other forums and they are full of various co...

Re: Aviation humour

Was looking along the shelves of the Royal Navy bookshop at the naval base at Portsmouth. One shelf had a row of about 12 volumes of Anecdotes and Jokes from the Royal Navy. At the very end of the row was a book entitled Anecdotes and Jokes from the Royal Air Force. I looked through some of the Navy...
