|Thread: flap/elevator setting|
That's very true that size does matter as smaller models has lower wing loading. Models tend to fly faster to compensate. You can scale models but not air itself so to achieve scale speed, you need lighter loading on the wings. Full size has greater penetrating power due to the mass of the aircraft.
|Thread: The Lockdown Restrictions Have Been Relaxed. Who's Been Flying?|
Is your Wot 4 nose heavy? Getting into a spin normally is going lazy circles and moving around slower and slower till the turning wing tips down due to lack of lift and some cases the wing tip is actually going backwards. Forcing the wing down normally enters a spiral dive. If you can stall your model, then I don't see that you can't spin.
Better start at 400 feet as you can give yourself time to recover
|Thread: RCM&E April 2020 issue chat|
I did enjoy reading “five ways to spray” in March issue (page 112) and was interested in reading about the compressor for next time and I was hoping to read it in the April issue but I can’t find it. I do hope it will in a future issue. Thanks

|Thread: Hobbyking site development.|
Thanks for saying I don’t support my local shop. I have been for years until they retired and closed shop. The other model chain, the high business rates killed them off so do I go on a car journey a few hours round trip to the nearest model shop just to see what they have? Or go on the internet and it mostly links to Hong Kong?
Have ordered last week of November as both items shown “in stock”. Now it’s 24th January and I have contacted them, One of the items has a warranty issue so it now changed into “back order” As it’s the Chinese New Year, I will have to wait to mid February for an update.
|Thread: Antonov AN124 Ruslan|
The AN 124 looks amazing and what’s the total weight including batteries?
I work out the maximum thrust could be 3,344g from the 4 EDF units and being hand launched helps.
|Thread: Real Model Pilots|
Hi Callsign Tarnish
Did your order come through? If yes how long did it take?
I have ordered two full bodied 1/12 scale pilots, one to be painted 5 weeks ago and have sent email via their website, no reply so am interested in how long it will take. I am in Surrey, UK.
|Thread: AND finally.....the 'Mini Jet' TSR2|
Thanks Tony. Any other info you might be interested that I can give you from the book or photos?
Happy to help. Keith
Hi Tony. About stretching the TSR2 wings, according to the book by Damien Burke, there was a study for the big wing considered in January 1963 for a possible strategic version as the small and highly loaded wing was a drawback. Version 1 has increased span to 44.36 feet and leading-edge sweep was reduced to 58.5 degrees.
Total wing area 840 sq feet. (703 sq feet for standard wing - span 37.14 ft)
Version 2, Span increases to 51.80 feet, sweep reduced to 48 degrees and wing area increased to 980 sq feet.
Tailplane in each case was left unchanged. But the increased take off weights meant the tailplane’s authority is reduced.
In the end, the proposal was a dead end as the cost was mounting and quietly dropped.
I will send a PM of photos taken from the book.
|Thread: Handley Page Heyford.|
I think the idea of 5 degs is for ground clearance for that model, as you don't want to have the lower wingtip touch the ground during take off and landing causing a ground loop and having possible damage as a result due to a wind gust. It will give more stability for the flight.
|Thread: Prostate Cancer|
My dad died from Prostrate cancer a few years ago and it's a horrible way to go. He had a scan and was treated about 10 years ago, then was given an all clear with regular after checkups around the prostrate for a few years.
But the cancer had moved to a secondary site (bowel & liver) and had spread unchecked till it was too late. (My dad was going private and went to see a specialist but he only checked the prostrate and didn't think of other sites then)
I am having a scan next week but most of my family in the past who have died are from cancer, two from heart attacks and another from stroke.
|Thread: 3D printer from Aldi|
Many thanks for your input.
The reason I added a spinner is really the top end and I would like one day to create a tractor spinner behind a normal plastic spinner as like in twin prop setup such as an Avro Shackleton which is a future project. (Would it be easier for me to modify a larger plastic spinner for this?)
I will build mostly in depron and balsa/light ply in high load bearing areas and fly in a slow graceful manner, that means as light as possible. It will be electric and hopefully the prop rotation speed will be slower.
Perhaps it will be more cost effective for me to have my 3D objects created elsewhere and for me do my business with a few guys on this forum, if not then I will go online.
I have found a Balco 3D printer from Aldi online for £249.99
Is that any good and can you create say a spinner from the machine or is it a soft material? i.e. No metal type filaments?
|Thread: Aircraft maintenance|
I enjoyed the film clip, thank you and is it a real emergency? Looks staged to me as film cameras from 1924 are heavy and bulky and there are plenty of them from several aircraft and on the ground. Gladys Ingle is well known for doing daredevil stunts on the aircraft and is a barnstormer. She sadly passed away in 1981 at 82 years of age.
|Thread: German WW2 Insignia|
I feel that if you do want to build a model of German Aircraft during WW2, are you glorifying the Nazis, No and I am interested in advancement and ideas of the arms race during that time. Raiders of the lost ark film has a swastika on the aircraft used in an action scene and it was acceptable due to it being "film art" in Germany.
It's illegal in Germany to have a swastika on any models and I wonder in say another 100 years in the future, will it still be the case?
|Thread: Gatwick drone incident|
I do hope the police helicopter in the air and chasing that drone.
Edited By Keith Simmons on 21/12/2018 17:43:57
I do hope the person or persons responsible for this do get caught as if they get away then there will be an aftermath.
If the drone or drones were preset in waypoints and GPS and not by radio control as it has been suggested, then what good will additional control be imposed on radio control use and the future drones won't broadcast user id or transponder over the wavelengths when queried by relevant authorities as User ID and/or transponder technology could be removed or switched off in the drone by that person.
To have and continue our hobby, I would welcome such technology as I don't have anything to hide.
I am sorry for the tens of thousands of passengers affected by the deliberate disruption of using drones over a major airport such as Gatwick. The Christmas spirit is ruined for many families.
Now the Army is called in to help. Hopefully it includes the SAS whom will soon catch the perpetrators and said specialist equipment is being deployed.
I am surprised that it is still going on and in my view, it's not the average joe doing this but bigger with deeper pockets? I have my suspicions but it's speculating and no place to be on here.
|Thread: Can a drone fly at 10000ft?|
Interesting, I have seen videos of near misses of military and light aircraft, so a camera exists, but not for modern airliners? There is a black box each for cockpit recordings and flight data. I would have thought an another black box for external views of the aircraft looking forward plus engines and flying surfaces (wings & tailplane etc)?
In the BBC report, the drone was at 20 times the legal limit so that's 20 x 400ft = 8000ft. (Unless the ground is at 2000ft above sea level? Which I doubt it.)
