Thread: dope lifespan
20/01/2020 22:28:22

I'm still using dope that I bought 30 odd years ago, absolutely fine, it may thicken a little and discolour but I don't notice any degradation in the way the product performs. I tend to buy a gallon, lasts me forever and far more cost effective than buying smaller quantities.

Put it in an old saucepan of boiling water with a dishwasher tablet, works wonders on castor. Dry it and run it wink

Thread: CAA registration take-up?

However, it now means that if they (the errant drone users) are caught, there is a legal framework in place against which to charge them. I’m by no means a supporter of this legislation, but I can see why they’ve done it.

That's one big if.

And there was previously a legal framework against which to charge those that flew drones irresponsibly.

The CAA are doing what they have to do and the BMFA have done a superb job for us in my opinion as nothing really has changed, okay we have to register, pay a fee and display a number on our models and that's fine by me.

It has nothing to do with safety, IMHO, more to do with commercialisation of the airspace we use.

Have you tried this servo in a different receiver output or a different servo in this output? Just to prove if the problem is the servo and not something else.

If a different servo doesn't display the same symptoms you can be sure it is the HS81 servo and then the best advice is just to replace the servo.

Yes in formal document or publication I understand the convention. This is a hobbyists forum for a technical hobby. Do we really HAVE to formally introduce acronyms (of which our hobby is full)?

Yes please when the acronyms are not common nor usual hobby related acronyms, such as esc. It is the first time I have come across STEM.

I think the BMFA have done well for us.

Have a look here, there is a response from 5 Star Adhesives, it goes back to 2015 though.

3) WIth Frsky you need to ask yourself how good you are on computer stuff. If the answer is not very then I would avoid.

Definitely disagree with this statement as I am no good with computer stuff but have had 6 years with firstly a Taranis and then an X12S Horus. Once you get your head into the logical steps of setting up a model the basics become clear and straightforward and then you realise the immense adaptability of the system to do what you want.

This was the first power model I built and trying to remember when I built it; certainly the early '80s, maybe 1982. I fitted an OS Max .20 and Micron r/c gear. It flew well as I remember with no nasty vices and with the .20 it needed a dive to gain airspeed for a loop. Happy days smiley

Hi Brian, PM me your email as I still have my instructions and can scan them in the morning.


Thread: How many on-going projects and unstarted kits do you have?
10/11/2019 22:05:55

Far too many and I have been looking to reduce; in part due to space.


Warbirds Hurricane

CAP P-47

Duncan Hutson SE5a

Mick Reeves Sopwith Camel

Acro Wot ARTB Kit

Wots Wot ARTB Kit

Sig J-3 Cub

West Wings Hunter

Cambrian Hunter

Flair ASK 18

Krick Grunau Baby

Wanitschek Astir

Craft Air Viking

Multiplex Carbon Line Alpina Elektro

Solent Sailplanes Ridge Rover

Crack Fokker Dr1

Micro Aces Bristol Fighter

Part Kits:

Brian Taylor Spitfire XIV

Brian Taylor Gladiator

Tony Nijhuis Mosquito

Tony Nijhuis Typhoon

Bubble Dancer HLG


Kirby Kite Sailplane

Minimoa Mo2a Sailplane


Hyperion CAP232

King Craft Pitts

And then, of course, there are the unfinished and restorations:

Phase 6

Skylark 4 Sailplane

Kyosho Libelle

St Leonard's Super Nova

Mike Trew Jantar 1 Sailplane

Svenson Stampe

Airsail Chipmunk

Ron Chigley's Tiger Tail

Fokker D8, modified from the Ben Buckle Plan

Brian Taylor Spitfire 1a

Small electric Spitfire

Phil Kent's Miles Hawk Speed Six

Falcon Indoor SE5a

Flair Fokker DVII restoration

Hangar 9 Super Cub restoration

Tony Nijhuis Lancaster repair

F3J Cassiopea restoration

And that doesn't include the free flight kits, nor my much reduced collection of plastic kits.

Frankly I have too many; far too many. This is why I am trying to declutter and reduce my collection to what I see as a manageable number...but how many is that?

You lot don't half get your knickers in a twist.

Sit back, relax and have another G&T, pint or whatever infront of the fire and dream of the amazing flying you will have next year, or the superb project you will build over the winter...

It is no big deal:

If you have a BMFA certificate do nothing until you renew and pay your £9.00.

If you don't have a certificate do the BMFA online test.

And then put a number in your model.

And for those of you who are going to give up the hobby over this; you can't have been that into it in the first place; get a grip.

Good god!!! I emailed them two years ago regarding sub standard fittings including this same issue. And I’m probably not the only one judging by the comments above!

Thread: Servo fitting and horns
19/10/2019 09:27:47

You only have to try it to see the difference Martin. If you have, let’s say one degree of free movement due to slop then the amount of slop that is transmitted to the surface increases the further away from the centre. Your percentages don’t tell the story. It is more important with smaller servos as the size of the gears and corresponding number of teeth on each gear will effect the amount of free play in the gear set.

No doubt the 3D machine you are talking about doesn’t use standard servos?

18/10/2019 23:58:35

Inner hole on servo output for better resolution and less slop/play. You don’t want to reduce the servo movement at the transmitter unless absolutely necessary as less servo movement results in poorer accuracy and ultimately jerky movement of the control surface. Just look at the way moulded gliders are set up. The inner hole on the output arm is too far out and to use maximum servo movement very often a hole is drilled 5 or 6 mm from the centre of the arm and the clevis is ground away to clear the output shaft flange or a purpose designed clevis/connector is used.

In fairness this is taking it to the extreme but as has been said in an earlier post, inner hole on the servo output and outer on the horn and adjust until you get the movement you need but only reduce the servo travel at the Tx as a last resort.

Wires touching somewhere intermittently with the vibration? Mice have chewed the wires, maybe?
