Model Airplanes from the 1930s-1960s

I know some on this forum will have experienced this first hand {me included] but I thought this
might make an interesting diversion.
Take note of safety standards in those days.

Shoot or Don't Shoot??? A man returns home a day early from a business trip. It's after midnight. While en-route home, he asks the cabby if he would be a witness, because the man suspects his wife is having an affair and he wants to catch her in the act. For $100, the cabby agrees. Quietly arriving...

Bit quiet on here innit.
Have a bit of a laugh. If you've seen it before you will still laugh again.

Interested to know which colour scheme you are going to use Andy.
The Valiant being the first of the V bomber Nuclear fleet. was also in anti flash white
Also the only one of the three to drop a nuclear weapon.
What a fabulous sight to see the V force fly in formation.

Kevin, Why would your club insist on seeing your LMA membership card. They should be BMFA affiliated and therefore you have insurance. You know we are a friendly bunch in the LMA and some very hard unpaid work is undertaken by our committee and others. Verbal abuse is something that does not usually...

The weather has certainly been freezable lately Richard.

What is the diameter of your two pipes chris. Total diameter too large can have a big effect on noise output.
If you have more than enough power in reserve you could reduce both of these.
Only other other alternative with the same silencer is to open the silencer and fit baffles.

Hi Pat. I had to repair my hangar 9 Valiant last year and my only source for the genuine heat shrink covering material was Hobby king. The exact colours too. I believe it may possibly be ultracote. This covering offers the same Qualities and Characteristics as Profilm, very high temp covering, stron...

Alan.just to put your mind at rest about the Rf gremlins you refer to. This is RF generated from within, not from the outside. In a Capacitor Discharge unit, there is a very high voltage spike emitted and it Must be screened metallically from the plug right back to the ignition unit output. If you h...

Alan, Unless you have knocked a chunk off the casing you won't need to resort to JB Weld If the casing is cracked only and you can clamp it or strap it enough to close the gap then a good quality super glue will do just fine. Just make sure the HT lead is fully home. A drop of accelerator and job do...

Hi Ray. Hope you don't mind but I thought these pics would help you sell
and be easier to view.

Not a lot of room up the front is there?
Maybe somerthing like this could interest you as an alternative.

Hi Martin. The main reasons that a magneto engine is difficult to start could be the magneto air gap, and/or the cranking speed. The voltage generated will be too low to create a good spark if it is not turned over fast enough. There is a technique to swinging a mag engine which some may find not to...

Before you cut any wires, just make sure that it hasn't got mechanically set differential on each aeleron.

Give this a try Max.

Hi Arthur. Although I have never used a powerbox kill switch, the reason for glitches is normally that RFI is getting back into the receiver through the powerbox to receiver signal lead. The normal procedure would be to place your ring on receiver plug lead close to the receiver. It won't hurt to pu...

. b1.gif . b2.gif . Two brooms were hanging in the closet and after a while they got to know each other so well, they decided to get married. One broom was, of course, the bride broom, the other the groom broom. The bride broom looked very beautiful in her white dress. The groom broom was handsome a...

Hi again Barrie, just a thought. Not all ignition systems are timed the same. Here is an extract from one of the forums which is relative to your engine ignition system. Only one small thing - the thor 45 manual states the timing for the original ignition as 12 to 14 degrees not 18 degrees BTDC. Ret...

Barrie, the method I use to secure my pitts silencer involves a bit of technowelding. The enlcosed pictures are self explanetary. It really isn't very difficult. Just research on youtube and do a little practice first. Thread the rod one end and make a shape to fit the silencer on the other. use a c...

Barrie, the ignition should fire just as the magnet is exiting past the sensor.
How do you intend to to determine how many degrees advance that is?
