Thread: New Legislation And Trainee Requirements
22/10/2019 19:33:37

The forthcoming new legislation allows an exemption for holders of a recognised achievement scheme e.g. the BMFA 'A' Test.

However, does this mean in effect that ALL future newcomer/trainee model aircraft pilots will have to pass the official online test, PRIOR to undergoing their BMFA 'A' test training or indeed the 'A' test itself if already in training?

Great for all of us already holding a BMFA Achievement Scheme pass.

Will there now be a mad dash to get 'A', 'B' tests done before the critical implementation date? Or does it not matter a hoot as the legislation online test can be taken as many times as required and cannot be failed!

Thread: Model Retrieval (or not)?
11/10/2019 21:29:35

Depending on the model (airframe) value to you, you could get a local tree surgeon to retrieve it for a suitable fee. One of our club members did this and the tree man scaled the 'unclimbable', (to us old crusties), tree and had the model reunited with its owner in barely 5 minutes. All without breaking, damaging or cutting any branches!

Thread: BMFA 'B' Test Video Available
07/10/2019 13:37:16

Geoff, having recently attended a BMFA Achievement Scheme Roadshow where Peter Willis and the BMFA team went through the whole process and ethos of the Achievement Scheme, I think I can reasonably assure you that you have nothing to fear.

Assuming your examiner is not pedantic, (unlikely), and asks about legislation and ruling that is not applicable to your type/style of flying i.e. you are not a display pilot, 'drone' pilot etc. etc. the test is about your achieving and satisfying yourself in your abilities to fly safely, with due regard to your fellow fliers, property and the environment.

As a mainly fixed wing flier myself, although technically able to be part of, for example a Helicopter or 'Quadcopter' test, personally I would feel I lack the day-to-day understanding of those types and their operation. Whilst the tests require some mandatory questions, if I were examining you as a non-display pilot, I can very easily find plenty of other relevant questions that do apply to your flying and which you as an experienced flier no doubt already know.

I'm sure you fly with care and purpose so taking this straightforward test merely adds to your personal satisfaction and sense of achievement.

Go on have a go, I'm sure you will enjoy it.

Just to let folks know, the BMFA have now released a guide to flying the BMFA 'B' Test.

Note: You are advised to have viewed the previous two videos (BMFA 'A' Test and Introduction/Pre-Flight Checks First).

Thanks to Peter Willis, Duncan Mcclure and all involved in the production of these very welcome guides for prospective candidates as well as their BMFA examiners!

Thread: 2019 Special Issue
27/09/2019 16:09:52

Revisiting this topic as the original author of the posting, I appreciate and concur with much that has been said.

Yes, I too am a 'seasoned' modeller and unlikely to build any of the plans in this 'Special'. My main point was that at least the magazine had some substance and content as opposed to the regular 'Advertorial' articles.

I think Cuban8 summed up the state of magazine(s) in general very well, Model Press and BMFA Mag especially so!

For the most part, 'we' are a mature (minority) bunch. Between us, have a wealth of diverse modelling experiences. What can a magazine, (on any subject), offer us that the 'World Wide Wonder' cannot deliver us in an instant at any time, on any topic etc. etc. (?) Yes, it is nice to have a book, a physical item in the hand, (we were brought up on that experience), but it is now restricted in what it can provide. Good or bad, multiple opinions, advice etc. are easily available online, this forum being a classic example.

As times have changed, I tend to consider 'RCM&E' as something to occasionally purchase to while away a train or plane journey where access to the net may not be possible.

As for 'New' modellers, if they are youngsters, (well much younger than most of us older flyers) their first port of call would probably be the www anyway!

Wow! Latest 'RCM&E' Special dropped through the letterbox today.

An issue with real CONTENT and not filled with 'advertorial' for a change.

It reminds me of the 'little' Radio Modeller of old, filled with text and articles on Balsa 'n Wood constructed models. Also, you can actually read the text as it's not printed against a non contrast background, so favoured of 'arty' publishing folk, bless them!

I often browse issues in newsagents and leave on the shelf as there's very little real 'content' or substance of interest or else same old, same old 4 or 5 contributors/writers/photographers, (good as they may be). I do appreciate fresh views from others.

Sincerely hope this standard can be kept up on a regular basis.

Thread: Aileron Thickness
13/09/2019 19:52:41

Yep, that American was meaning 'Round(ing)' the leading edge of ailerons and also making them (slightly) thicker than the rear of the wing they attach to. As for sharp/straight trailing edges i.e. the very, very end edge of the T.E. taper, agree with Don.

Many an aerobatic type has a 'reverse taper' trailing edge, especially seen on rudders. This, it is suggested assists in preventing 'fishtailing' .... wiggle-waggle, wiggle-waggle!

Meanwhile Don, I hope I'm not an idiot but I think it's a brave person who doesn't admit they've never done some idiotic things in their time, even when flying model aeroplanes!

13/09/2019 17:35:07

Interesting replies.

I have a American flight school book, ("Airplane & Radio Setup" by David A.Scott), which states do not 'bevel' ailerons but 'round' them. Also ... make the ailerons thicker. Author Mr Scott, who runs a long established R/C flight school and is also a qualified full-size display pilot, describes the advantages/theory of these actions. i.e, re-energize (US spelling LOL!) the airflow over the ailerons to maximise control authority and generate a linear control response. Also ... his 'Rule of Thumb' quote" Raise the aileron, elevator and rudder approx 1/16" each side - 3/32 to 1/8" thicker overall"

You can check out his Flight School books and download illustrated sample pages.

My 'flying field' experience, seal the gaps first and foremost, all the other ideas???? maybe/maybe not, my skills can't deduce any discernible improvement (or degradation!).

Thread: Shortage of 35% (100cc) aerobatic kits in the U.K.
04/09/2019 11:41:13

Considering the shortage of kits in ALL retailers, they must be having a very hard time at present. Most fliers don't buy Radio sets every '5-mins' either. Any retailers here wish to say what, if anything much, is being bought at the moment?

I do appreciate many of us here, build from plans, 'roll-our-own' designs etc. but we are a minority of a minority if the evidence on flying sites I visit are anything to go by.

Thread: Ladybird 1.5
03/09/2019 14:00:32

As a youngster growing up in Cardiff, I built the original KK 'Ladybird' F/F model. Powered by a Cox 049, as a complete novice, I launched the model with a full tank of Cox finest glow fuel at Ely Racecourse [Trelai Park(?)].

Up, up and away in spiralling circles until the 42" wingspan was a mere dot in the sky! A mixture of joy, (at the flight), and sadness I would never see my tissue 'n doped pride and joy again.

Off home, I wondered if pocket money shilling might stretch to a new model replacement from Watkins, Ironmongers at The Insole parade of shops or even if very lucky, grandad would take me to Bud Morgan (Model Shop) in the cities Castle Arcade.

Anyway, a few days later, about 6 of an evening, a knock at the front door. A Forestry Commission workman stood in the porch clutching my lost treasure. It had apparently flown way over the nearby hill toward Penarth and landed in the trees that (fortunately for me) were being worked on.

And so that weeks (and some!) pocket money was given to the workman as a reward.

My name & address had been scrawled in faint 'Boys Biro Handwriting' on a panel near the tail which fortunately hadn't punctured in the branches.

Great to see 'Ladybirds' fly on in Cardiff!

Thread: Max Thrust Riot - Upgrades
30/08/2019 19:13:01

Sorry to hear of ALL your 'Riot' woes Jeff.

As I often say, most ARTFs made down to a price, not up to a quality.

My 'Riot' was an 'airframe only' purchase to which I replaced: Motor (now 4-Max), ESC (4-Max), Prop (balanced APC), Spinner (Ali back-plate+balanced), HiTec mini servos all round with ball-link clevis = absolutely no free-play linkages, Undercarriage 'Chinese metal' bolts replaced with DuBro axles, u/c fixing also improved to prevent pulling out, larger wheels too. AND those horrible metal snakes that bind in the outers drawing substantial current=A, not to mention making precision control nigh impossible! Replace!!!

LiPo area 'hollowed out' to easily accommodate a 3S 3300mAh pack plus secure with velcro strap. The original plastic 'rats cage' urgh!!!

C of G start as recommended in instruction sheet then adjust to your taste/preference. Many end up removing that lump of weight, you may or may not find that trim comfortable for your style of flying and requirements.

Yes, I've tried that HK C of G gadget 'orrible, now use either the Multiplex or Great Planes C of G devices = no problems.

Flying - Fly the 'Riot' in all winds and weathers, no problem, now, (with all the mods), a great hack model, loads of them in our club.

Thread: Incidence Meter/Gauge Measurement
30/08/2019 17:33:01

My old Robart Incidence Meter/Gauge has given of its best and I am in need of a new Incidence Meter. Reading the reviews it seems the quality of currently available and advertised meters is less than ideal! This includes the Robart, Multiplex and E-Flite devices, all seeming now to suffer from inferior materials, construction and resultant inconsistencies in readings & results.

I have checked the helicopter specialist suppliers, thinking they surely must have accurate meters for setting blade angles, tracking etc. nothing apart from the less than ideal brands already mentioned.

So, any recommendations for a consistent, precision, quality incidence meter?

How many even bother to check and correctly set incidence(s) these days, given the dominance of ARTFs???

Thread: Hands free mobile calls
22/08/2019 16:17:24

I venture the majority, (not all I appreciate!), of the folk on here are retired and highly likely to have less of the working life pressures e.g. paying a (big?) mortgage, holding down a high pressure job etc. etc.

Consider for example the Sales Rep, rushing from one prospective customer to the next and the call from the boss comes in on his hands free whilst driving ... 'Bloggs you're sales figures are rubbish, (or words to that effect!), you're fired!!!'

Where is the drivers attention and focus likely to be????

I am reminded of the Bob Newhart comedy sketch, (available on the 'Tube) regarding smoking and Walter Raleigh ... roll on when driving is similarly looked upon as absurd and no human has to drive, the 'pods' carry us in safety where ever we want to go. No more tail gating, speeding in fog, 'no light' , no indicator dummies, kiddies in boom, boom blue racers, traffic jams etc. etc. Everyone can relax, chat on the phone if they wish, read a book or latest RCM&E, play an instrument, do something really useful instead of just sitting in a tin box on wheels getting overheated at others antics on the road. If only ....

Thread: RCM&E Dec 2018 - Ruckus Review Update
16/08/2019 12:01:43

As per my experiences, (see review section), the 'Ruckus' out-of-the-box is a BASIS for a general hack/sports model, as others have found. Quality of items as supplied, (U/C, axles, clevis, snakes, motor, ESC, prop, spinner, canopy retention and placement of these etc. etc.), can be very subjective and change a mediocre / 'duff'(?) model into a joy to own and fly. Like most, if not all ARTF, creations from the far east, IMHO they are made down-to-a-price, not necessarily up to the quality seasoned model builder/assemblers would prefer. Although much of the 'Ruckus' shares common parts with the 'Riot', I still find my 'Riot' the better of the two aircraft. Several 'Riots' have appeared in my club and are flown by a range of pilots, from relative inexperienced to 'hooligan/chuck it about' merchants! Each to their own. Enjoy!

Thread: Multiplex Cockpit Sx 9
15/08/2019 15:42:21

Whilst on MPX 'Cockpit' timers ...

Can you, (easily), stop the TOTAL flight time counter (Timer 2)?

[I appreciate you can on the screen by touching T2 'Stop' - I'd prefer my (total) flight time (not motor run time) on a on/off switch].

i.e. Flick 'On' as soon as wheels leave the ground and 'Off' when model touches down, not having to wait until after you taxied back, made LiPo safe etc. etc. Explored the timer screen and options couldn't make Timer 2 stop trying to assign to a switch.

14/08/2019 12:07:47

Hi Mike,

Just experimented on my 'Cockpit' Tx:

Depending on how you have your 'buttons/switches' assigned, you can toggle the sound on/off but 'Angela/Frau M' on 'Timer 1' keeps on speaking regardless.

The default(?) sound button is on the top left-hand side labelled 'Teacher/Vario'. Alternatively, you can touch the bottom right square next to the battery status and toggle through that. Maybe our resident MPX expert Frank S. knows.

Still reckon a decent manual would save a lot of head scratching for mere mortal MPX users!

(e.g. What do the 'Blue/Orange' adjustable bars you find by sweeping several steps to left signify with 'enable slider' tick box 'System Information 3' it says????)

A fantastic system nevertheless.

Thread: Tucano 45" Decal set

Stan Yeo (Phoenix Model Products), makes a 50" Tucano, he may be able to supply a set of decals used in that kit.

Thread: Playboy Senior

As others have mentioned, the tail end, (especially), needs to be kept light.

I built a vintage 'Air Trails', Ray Heit design the 'Scrappy', (similar to the 'Scram'. All traditional fabric and doped covering, couldn't get it anywhere near a safe balance point. In desperation, I ended up recovering the tail plane and fin/rudder assembly in tissue. I was amazed at just doing that simple little thing, made a huge difference to achieving a safe flyable C of G.

Also, with the advent of LiPo replacing the 'lead weight' NiCad cells of earlier electro-flight days, that has made the C of G balancing act more of a challenge!

Thread: Multiplex Vario/Altimeter vs UniSens-E
05/08/2019 13:33:15

+1 For the Unisens.

Can't see the point of daisy chaining multiple (expensive?) MPX telemetry units when the Unisens does most if not all at the 'tick box' selection on set up. Very small unit too. Also can work with other radio systems if you stray from MPX!
