Thread: TN Folland Gnat

Posted by Graham Stanley 3 on 09/03/2020 15:51:44:

Thanks both. I'm concerned about the weight and (lack) of thrust. I'm measuring about 440g of thrust, 3S set up. I was hoping for more installed thrust, and potentially even more in the air. Time to go an get a fresh battery and retest..

HI Graham, I ran a static test on my 3S FMS unit and while kitchen scales are variable in the level of trust, I did unsurprisingly find that the battery pack type made a difference; the lower the C rating, the lower the power. Using two different manufacturer packs (both 35C saw about 27g variance), but using the better pack to repeat the test when the room temperature was 8degC cooler saw a drop in thrust of 24g.

It's nice to see SMC and Slough having their ads back in the magazine. Going on line is ok, but not as good as seeing it in print. Remember when Slough's ad were 8 pages long!

I totally agree with Paul's comments about the SMC and Slough ads. Somehow looking over all the goodies is more enjoyable than an online search, and often gets you thinking about other goodies too that you might not have.

Thread: TN Folland Gnat
09/03/2020 12:49:47

Love the build myself and my son are both building TN Mini Jets. I have recently found time to start the Gnat while my son has started the Hunter.

We are both using the FMS 3S unit and while I am finishing the Gnat as a Red Arrows one, the Hunter is going for camo finish, but have considered it being finished in silver.

Both aircraft types lend themselves to many options on colour scheme.

Both should be finished in time for some decent flying weather - I hope.

Thread: Rhapsody plan - old thermal e glider from balsa cabin
19/02/2020 13:09:28
Posted by Ian Dewar 2 on 19/02/2020 12:39:14:

Hello. I've had a Rhapsody since around 1994...originally flew with its Graupner Speedgear 600 and 7 cell nimh which was ok for its day but a slow climb. Some years ago I upgraded it to a brushless inrunner and 2200 3 cell lipo....what a difference! More recently I have added some of the Hobby King servoless airbrakes as it didn't always want to come down...

Whilst I believe the Rhapsody is based on the Fantasia, it looks to me that the fuselage on the Rhapsody is almost twice the width of the Fantasia, as mentioned above, probably to accommodate the nimh pack, which you don't need.

I believe I still have the plan if you are desperate, but I think to make your Fantasia into a Rhapsody, then you would need a complete new fuselage.....not worth it, I guess. I suggest a good dose of downthrust as even with the Rhapsody designed for electric, I find I need to mix in elevator with throttle.

My Rhapsody has been a great glider and hopefully has many more years left in it!

I would concur with the increased downthrust recommendation. I have on three gliders increased it when moving from brushed to brushless/LiPo set ups. My Bixto had nearly half as much again to the plan (the motor performance difference was quite significant and I also on that beefed up the wingspar). My Sonata E had a small increase, as did a scratch built.

David, the Fantasia would have used a heavy Speed 600 ferrite motor and even heavier pack of 7 or 8 sub-c cells which probably accounts for the shorter nose of the Fantasia and wider fuselage to accommodate the large battery pack.

i suspect if you fit a modern brushless motor and 3s 2200 mAh LiPo in your Fantasia all will be well.

I would concur with Piers' comments in regard to the use of a modern brushless/LiPo and rc set up. The fact that there is not much difference in weight of the standard glider WITH a then standard 4.8V Rx pack and standard servos and Rx. Weight can be saved or utilised effectively with servo size used too.

Thread: Elan 100 Build
04/02/2020 13:01:53

Really interested in the comments about the Elan during the build and 100S competition. I like a number of others on here am disappointed how competitions are now spoilt bi the hi-tech approaches.

I have a Balsa Cabin Ravello that I built some years a go now that I still enjoy flying, and while some of the more modern designs and materials used make for good performing gliders they are not as much fun. Perhaps that discourages others from having a go?

Or maybe I am getting old lol.

Thread: 2020 Southern Show cancelled
04/02/2020 12:49:22

It is a shame and hopefully it will not suffer next year when the event is held next. Always very hard especially when circumstances are beyond the organisers control.

As to the debate about gate and stallholder fees, it is extremely rare that any event does not cost to organise, even if the landowner waives any fees, organisers still have to cover things such as insurance, toilets, emergency service support etc. The effort and pressures deter many, which tends to leave the position of a few clubs etc who want to help boost their club coffers and interest etc being likely organisers.

Personally, having been involved in organising model shows or events it is often the case that many fail to understand the depth of time, effort, etc required and we should be thankful there are people and clubs etc who do, as otherwise there would be hardly any shows or events. THANK YOU TO THOSE WHO DO ORGANISE OR PROVIDE SUPPORT TO SUCH EVENTS.

Thread: CAA Registration Impact on STEM Activities
07/01/2020 14:56:17
Posted by Alan Gorham_ on 07/01/2020 14:11:41:

If educational bodies are aware of registration, then why is registration a blocker to a project?

If the Educational Lead (teacher/lecturer) is not prepared to register as an operator then that is down to them, not the registration system.

It could be argued that there is some real-world educational value is taking students through registration to demonstrate compliance?

The BMFA offer STEM projects, the biggest being the Flight Test Challenge (or whatever it's called now) but each BMFA area should have an Education Co-Ordinator. They are frequently contacted by educational establishments to help support projects such as this.

Educational bodies such as schools do not appear to be aware in this instance, and nor potentially are STEM bodies supporting the schools.

I agree with your comments on the Educational Lead and about the educational value in taking students through the registration process.

I suspect that as far as the 'Educational Lead's' are concerned that they are mainly rank and file teachers who don't have an outside work interest in model flying which does not help matters, but equally is possibly why we such limited promotion of after school hours activities for students these days in a number of activity areas.

However, as far as industry STEM bodies possibly now refusing to support projects. It is as much about the almighty mess made in the reporting, visibility and guidance of registration that has led to the adoption of a negative position.

It might help be offset if there is increased visibility or liaison by BMFA Education Co-Ordinators.

I know that in many instances opportunities only exist for activities in part by school/college/education staff being prepared to go the extra mile and the support of industry and sporting bodies that anything much happens these days.

07/01/2020 13:34:31

I know! We are all fed up with all the chat about registration etc. However, despite myself and I am sure others who raised their concerns about impacting STEM activities, I wonder how many are seeing the fallout now registration is live?

So I am a STEM Ambassador within my organisation, and talking to a fellow colleague they advised me of a project they are supporting for a local school. Said project is to design and build a model aircraft that can carry a camera. The team have been working on it since just before the announcement of the requirements, and are building their model. A lot of good work had been done by them to date. When I mentioned the need for Operator registration etc they were surprised.

This prompted communications within my organisation (which is multi-national) and there had been a general awareness and guidelines to avoid undertaking any such projects that involve model aircraft when registration requirements became more public.

I will not go in depth on this as there are some ongoing discussions but wondered how many others are involved in STEM and have already come across problems?

From what has come to light from within our own STEM people and liaisons with other organisations there are some issues and concerns for the future of STEM activities involving model aircraft.

Key observations:

Not all STEM individuals or organising bodies are aware of the registration.

Not all schools or colleges are aware of the need for registration.

Organisations supporting STEM activities are already blocking any such model aircraft based projects.

Responsibility for registration of operators? Should it be the project team/teacher and/or STEM support from industry, etc?

Apparently a few projects have already been blocked and sadly the team's enthusiasm lost as a consequence. This is not good for encouraging the next generation of engineers be it in model flying, aerospace, or engineering in general.

It would be good to know whether others have already encountered such issues and how they have overcome them. Equally I wonder if bodies such as the BMFA are already aware of the impact that is emerging?

Definitely the Gnat for me and Hunter for my son. I suspect that the Lightning and Hawk will follow although want to also do the Provost.

Thread: TN Hunter Plus

Glad its the TN Mini Jets. I am about to start the Gnat for myself, and my son has the Hunter.

Thread: BMFA
18/12/2019 12:53:05

Amen from me on that. The BMFA gets a lot of stick at times but knowing of other battles in the past such as CB days etc I think they have managed a fair degree of damage (nee political) limitation which is not easy. One must hope that in time the government sees the ludicrous need and reverts back to previous practice.

In the meantime, well done BMFA I continue my membership and may everyone have a quiet and joyful Christmas.

Thanks for that info kc I always loved the Taurus as a youngster in my early years, and might have to build one for the fun of it.

Thread: Merry Christmas

Wishing everyone a very Merry Christmas and wishes for the new year. May we all get fair weather and lots of flying in.

Thread: BMFA numbers. Is this true, or a gross exaggeration?
13/11/2019 12:56:59

Some very interesting and wide ranging comments. Realistically, the world and society evolves and changes. There are many other distractions for spare time these days, and some of the fascination in technologies i.e. aerospace lose some appeal. My son is very much a product of the modern era, yet he is interested in model flying and rc especially and is learning to fly because while he ight fly simulators etc he has seen that it is still very different doing the real thing. Numbers decline also, for things like cost of living, family priorities, etc, etc, etc.

One time, amateur radio was seen as popular and challenging (and also led to a number of people doing both radio and model flying, but these days there are far fewer people because communication is a lot easier by other ways and people cannot experiment like they used to, amongst various reasons.

Model flying has evolved and it is probably fair to say there are far fewer builders from scratch/plan or basic kit. Yet at the same time there is now a sizeable number who derive pleasure from ARTF's, and there are perceived to be fewer challenges to grab peoples attention or desire. Yet model flying has evolved a lot over the decades and is likely to continue to evolve.

Thread: David Vaughan P-51B
05/11/2019 13:12:43

I can't help following this thread out of interest, and must say the idea of the BMFA exhibiting some of David's creations as massively appealing, as along with separately perhaps those of some of the other greats like Mick Reeves for example.

As pointed out already the detailing on models has been superb over the years and really did take off from the mid/late 70's onwards I think in this country. Articles written by the likes of David, Mick, Brian Taylor and Gordon Whitehead I think re-focused many of us in efforts to detail our scale and even semi-scale models.

Aside from reminding those of us who were inspired originally, it might also newer generations?

Thread: Veneer lifting problems
15/10/2019 13:03:55

I have found that where the veneer has split or lifted that using copydex gives a stronger bond than PVA. This was advice I was given back in the early 80's when making and repairing foam wings, and has worked for me all these years when necessary. I always use dome weights to help hold the veneer down for a day or so to ensure a strong reliable bond.

With regard to finishing the wing I would opt for using glass cloth and epoxy resin rather than dope and nylon as if the wood is old it is likely to have more open pores allowing dope through to attack the foam.

Thread: 2019 Special Issue
02/10/2019 12:46:12

Personally I felt that the special is special as it is different from the normal issues. This is how it should be (thinking back in the past to such specials that set aside normal magazine content). Great work to the team for this month and I think it just goes to show there are many options for the builder and you do not need to have artf's or foamies.
