Re: Help needed locating Retlas Firefli plans

Dave someone mentioned they had seen my reply about Terry Salter. They said he joined the great model club in the sky a couple of years. Sorry to get your hopes up.

Re: Help needed locating Retlas Firefli plans

Hi Dave, Retlas kits were marketed by Terry Salter (Retlas being Salter backwards) who did live in Dover. I know he left the modelling business years ago but may still live in Dover in an area called River. May be worth a search in the phone book because he may have hung on to some plans etc.

Re: New Member Intro Thread?

Hello Andy, welcome to the LMA. I remember you from when I used to organise the LMA shows at Old Warden, they were halcyon days. Sadly we had a great deal of misunderstandings from the management when a big reorganisation took place, 20 years ago, of what the LMA were trying to do for the good of th...

Pity about that Alan especially with his expertise, still you can't live their lives for them. I bet he comes back to the hobby later on as many people do. I think if it is in your blood somewhere you never lose the fascination.

Hi Alan, yes he certainly does and then some! He is the LMA member who flys the huge 7/8th scale Pitts Python. I keep telling him his models are too big, transport is not easy and putting together a model that weighs 138Kg for a couple of flights per day is a nightmare but he says 'if you've got to ...

Re: Feb 2015 Aeromodeller mentions the LMA - but ...

A couple of years ago whilst attending a few fly-ins for mainly large models but not exclusively, I took along with me a Shoestring and a Phantom Mite control line model. I think there was more interest in the control line flying with the modellers than anything else, people were lining up asking fo...

Re: 1/10th scale Blackburn Beverley.

Hi Malcolm, I'm sorry to say this but I feel quite demoralised and inadequate! You have been carving wood for some considerable time now and your workshop looks much too clean and free from shavings. I make a mess putting an 'almost ready to fly' model together. Congratulations on being so orderly.

Hi Malcolm, noticed in one of your posts about constructing the nose leg gear. I have successfully fettled extreemly robust units using the gas struts from hatchback cars. Dis-assemble the strut to release the gas pressure etc. and you are left with a rod in a tube with an end which has a strong fix...

Re: 1/10th scale Blackburn Beverley.

There is an interesting item in this weeks Flight International when Tom Sheppard landed a Beverley at Farnborough in 1969. Suspecting brake failure on touchdown Sheppard selected full reverse pitch and pushed in a lot of down elevator to keep the wheels on the tarmac. The Beverley's large elevator ...

Re: 1/10th scale Blackburn Beverley.

Hi Malcolm, this BMFA/LMA problem has been with us for years, in fact my local club decided to opt out of BMFA affiliation many years ago when there were several insurance covers available to be left up to the individual member which one to use. Actually the BMFA and our insurers are the same so tec...

Large canopies

I have been looking for an easy (cheap) way of making a large canopy without the need for vacuum forming and plugs etc. On channel 4 there is a programme featuring Guy Martin and his quest for speed, on series 2 episode 1, in an episode called 'Tandem' the team had to build a streamlined tandem bike...

Re: Battery Backers?

Hello John, you don't need a diagram. In the positive lead from each battery fit the diode in line between the battery and receiver preferably after the switch ( I presume you are using a separate switch for each battery) otherwise you may prevent your charger from working if it connects via the swi...

Re: Battery Backers?

Hello Rob, I don't advocate parallel batteries but on the subject of sudden short circuit, whilst in flight, of a battery (insulation breakdown etc etc) then a diode in each of the pos feeds from each battery would provide protection. The diode would prevent the good battery going to ground via the ...

Re: Battery Backers?

Hi John, then you have a fault situation which is not what we were talking about. You don,t normally connect batteries in parallel in real life without diode protection! In fact I would not suggest batteries in parallel anyway. Dave

Re: Battery Backers?

If you have two battery packs of the same VOLTAGE regardless of AMPAGE, one flat and the other fully charged, and you couple them in parallel the fully charged pack will see a battery of the same voltage capacity as itself so it will not try to seriously charge the flat one. It will charge at very l...

Re: Servo interference

Just a thought, had this problem with a receiver a while ago. The receiver was fine when engine not running but servo jitter occurred when running, tried opto isolators, ferrite rings etc but no joy. Changed the RX and all was fine. That 'dodgy' receiver is in a glider now and, without engine interf...
