Thread: Interesting reply from email to Richard Moriarty, CAA

and the (awful) answer by Jesse Norman:

"Department for Transport Ministers and officials have regular discussions with the CAA, including on the Drone Operator Registration Scheme and competency testing requirements, which will apply from November 2019. These will apply to all unmanned aircraft below 250g, including drones and model aircraft.

Good to see they have a firm grip on their own policy!

Do I read this right?

You would still get to fly any sub 250g stuff, anywhere you wanted, of course, without any of the test or registration.

...................................

 

From CAP 1763:-

"You must not fly a small unmanned aircraft within the flight restriction zone of a protected aerodrome without first ensuring that you have permission to do so. The volume of airspace that comprises a ‘flight restriction zone’ is outlined in a table at paragraph (7) of article 94A. The flight restriction zone is active at all times and applies to all small unmanned aircraft of any mass (even very small ‘toys' )" .

So no, you can't fly sub 250gm stuff anywhere you want.

The second communication is from the developers of the registration system

Sparck? They put out an awful survey last November.

Steve

Yes, that's them and that's the survey they referred to.

Dick

Two recent communications:-

A letter from my MP (after two weeks). Generally supportive and reporting that he was an enthusiastic aero-modeller in his youth, and including a copy of the letter he has sent in our support to the Secretary of State for Transport.

The second communication is from the developers of the registration system asking me if I would be prepared to join them in the St Pauls area of London for an hour or so to assist with “user research” i.e. test using the system (apparently I completed an earlier survey).

I have replied that, as the CAA now propose to charge me £16.50 a year to register at no benefit to myself, I am no longer prepared to provide unpaid input to the system and that I might be able to help if he is prepared to negotiate a fee for my time plus expenses.

I don’t plan on holding my breath.

I completed the CAA on line consultation, then last week emailed the DfT, the CAA, and my MP.

I received the standard acknowledgement from the DfT, but nothing so far from the CAA or my MP. I have just emailed both the CAA and my MP again asking for at least the courtesy of an "acknowledgement of receipt", and will continue doing so unti they respond or the BMFA says "stop"!

....... Just looked at the Picasim site, free download I see but not sure if it works with a TX (mine's a Spektrum Dx6i) or mouse. Any suggestions about this or an alternative?

.

Picasim works fine with my Jeti Tx via the usb connection, but I have no idea how it would work with Spektrum.

There is an exemption for flying control line models in a FRZ, but that doesn't mention exemption from registration.

I am not aware of any exemption from registration for CL flyers, who are refferred to as "remote pilots" in the above doc.

From CAP1763:-

"the “SUA operator”, in relation to a small unmanned aircraft, is the person
who has the management of the small unmanned aircraft.”

Not sure how that would be possible without the "operator" being present on site.

What can they do about it if we all refuse to register? Nothing. Think about that. About time that we stood up to these jobsworths.

It would only take a few large fines to test our resolve, and I am sure that would be worth it from their point of view. Lets face it, one trip to a random club by the police would be all that it would take.

From CAP1775:-

1.2 All those in the UK operating drones or model aircraft between 250 grams and
20 kilograms must register by the end of November 2019. From the same
period, remote pilots will be required to take an online safety test. Failure to
comply with these rules could lead to a fine of £1,000.

Just repairing my under 250 gm model.

From the manual:-

"Troubleshooting ………….. If you have trouble arming the controller (and the throttle trim has been set to minimum), enter the programming mode and try changing the set-ting to 1.1ms to 1.9ms in Programming Menu 4 to see if it helps correct the problem. If it is a computer radio, you may alternatively increase high and low throttle ATV (endpoint) percentages. Note: Increasing the high ATV will not have a consequence on arming issues, only low ATV."

I suggest going into programming mode and try setting up the ESC endpoints again.

What amazes me is that a folding prop can hold up under such high rpm!

They are mostly handmade specials, but some commercial options are available.

Have a look at what I pay for a folding 18" prop that will take up to 8kW (done it) at a mere 8,500 rpm for my F5B planes.

Dick

18/04/2019 10:31:52

The Germans hold a speed event for such planes every year, and 500 kmh is not unusual. They are even approaching 300 kmh for an under 250 gm class of model. Have a look at some of the planes and equipment on this website.

....................

The plate pulling out at the front can simply be down to glue as you say , but there is tremendous shock force on that joint when it hits a bump. However i have found that wrapping a little brown paper or even better glass cloth over the front edge of the plate and onto the rest of the wing stops the issue dead.

........................

I think that for such a beautiful model, when nerves must have been pretty stretched , you did really well . Next flight you can spend a bit of time investigating the slow speed characteristics mid flight (at height) until you feel confident to slow the spit down more on approach .

...........................

I liked the way you used a two blade prop for the test flight too. Just go easy with the throttle when you fit the bigger prop as torque becomes very apparent . I ease on the power and never let it swing left ,

Hi Richard

Thanks for the sugestion for the UC plate repair, I will,definitely try to get some glass cloth in there during the repair.

Slowing it down and low speed handling is something I can work on more in the next flights. My checks of the stall charactersistics during the maiden showed it is very gentle with the nose just dipping slowly straight ahead, and I have already had comments on how stable it looked in my low and slow final turn into wind for the touchdown.

The 14x8.5 APC two blade prop was fitted to avoid damage to the (expensive) four blade during initial testing and flying, but it certainly flies well on that. Now I know the rate of consumption from that first flight (1520 mAh out of a 3700 for a 7 min flight) it seems I will have plenty of time to practice landing approaches on the next test flight. Most of the flight was on 250 watts or less - not bad for a 6lb plane.

Maiden flight yesterday, and very pleased with it, but ……….. the landing

On touchdown I ripped the RH undercarriage leg and half its mounting plate out of the wing. You can see it exiting under the LH side of the fuselage in the attached photo.

The inquest shows that I might have been a bit too light with the glue in that area, as the landing wasn’t THAT bad, although there might have been a bit of yaw at touchdown.

I have already “dry fitted” the UC back in the wing (see photo) and everything still lines up and works OK, so an easy repair.

MJ627 had its maiden flight yesterday, and an excellent video put together by clubmate Chris can be found here - thanks Chris.

At our club we have a system of inspecting new models before they are flown to ensure safety and noise compliance, and very useful a second set of eyes looking over a model has been, so getting it checked out and range tested was the first task – thanks Martin.

Next was the photo opportunity, before I tried to break it, after which I changed from the lovely 4 bladed Biela prop to an APC 14x8.5 and proceeded to check out the ground handling.

I fitted a castoring tailwheel as it seemed like a good idea at the time, since then I have heard lots of horror stories about them. It certainly made manoeuvring on the ground easy, but trial take off runs proved hilarious. Thankfully I had fitted a gyro assisted receiver and once I had selected Heading Hold and cranked up the rudder gain the take of runs started to look possible even in a crosswind. So, I fitted a fresh battery and tried to calm my nerves.

I elected to do a crosswind take off and landing because the into wind runway would have had me trying to land down-hill out of the sun, and I didn’t fancy that. The take off actually went smoothly and it lifted off after a reasonably short run. I don’t like flying with a heading hold gyro as it seems like a fight between me and it, so the first half a minute or so was a bit jerky until I remembered to switch back to normal damping mode gyro.

The rest of the flight went OK with trimming out both "UC down" and "UC up" flight modes, checking the stall, and generally getting used to flying a different type of model to the ones I am used to – e.g. there were some comments from the inevitable audience that the rolls were a bit faster than normal with a Spitfire!

A few trial landing approaches from opposite directions (crosswind remember) showed that it didn’t want to come down in our field without a headwind to slow it down. I eventually settled for an approach that would let me turn left into wind if I couldn’t get it down on the first runway. The landing didn’t seem all that hard but the UC will soon be re-fitted (I will cover that bit in a separate post).

The flight time was about 7 minutes and telemetry revealed I only used 1520mAh out of the 3700 mAh battery, with a peak power 530 watts. I learned a lot in that one flight and am really happy.

Low level photos as requested by Richard.

Thread: RIOT - why 2.4 GHz only
31/03/2019 15:09:16

From the late 1980s on I was using Fleet 35MHz gear with up to 1kW brushed motor setups without problems. In the early 1990s I changed to Multiplex because I liked the software flexibilty and tray styling of the 3030 transmitter - still no problems, as expected, with a mixture of Fleet, Multiplex, Schulze, and Simprop receivers.

The arrival of brushless motors and changes in battery technology resulted in even higher power levels being used with my 35MHz gear.

The only reason I changed to 2.4 was the reduced risk of interference from other users.

I think we would all be interested to hear a little more about the mods you made . I for one wouldnt mind a few low angle pictures of the model as if you were about to get in . On short grass or tarmac if poss.

.............Richard

Hi all. Thanks for the nice comments - it is largely down to the information and enthusiasm of everyone else who has posted on this and other build blogs that I have managed to complete the project.

Richard - I will try and get some photos of that type over the next week and add them, and some details of the mods., to this thread.

Possibly - he has a similar vacant look on his face.

No doubt fearful of having to actually fly it smiley

I am please that this thread has resurfaced as I have just got my Spitfire about ready for our clubs pre-season static show.

I am not really a scale modeller so this was sort of a new venture for me. Add in the fact that I converted the kit into a two seater means I certainly jumped in the deep end. It is by no means perfect, but I am reasonably please with the result. I might do a bit of weathering to improve the appearance if it survives the maiden flight, but that could be a week or two away while I summon up my courage!

It weighs in at 2795gm (6lb 3 oz) ready to fly with a 3700 4s Lipo installed. A bit heavy perhaps, but that has been affected by the modifications to two cockpits and pilots,and my decision to install twin elevator servos (had a couple of servos fail recently). It also has telemetry sensors installed which obviously adds a few grams.

I have to say thank you to Richard for an excellent kit that made my job a lot easier than it could have been for a newby to scale.

Thread: Does your club prohibit the use of after-market receivers?

15.14 Mix-and-Match Tx and Rx Using different makes of transmitter and receiver is common practice .......................... responsibility of making sure that your equipment operates correctly.

Above excerpt from the BMFA Members Handbook.

Make of it what you will. But if it all goes pear shaped, am I covered by BMFA insurance or not?

..................... Why has the BMFA singled it out?

...................

I see nothing in there that suggests you can’t mix brands, just good advice as to what you need to look out for if you do.

The BMFA have not “singled it out” – it is part of a long section of advice and guidance on a whole series of issues including batteries, aerials, crystals, and BECs.

If you are worried about insurance then ask the BMFA – but note that someone already has and we had the answer quoted earlier in this thread!
