  1. Yesterday our BMFA ACE visited to assess an examiner and as part of that process I passed my A cert, the examiner also got signed off. 👍 I had been practicing in our prevailing SW winds so yesterdays fluctuating N/NW took some recalibration doing the manoeuvres in reverse, however a couple of practice flights sorted that. The Boomerang is now being retired as a winter/bad weather hack and onwards with my B cert.

  2. Wow! Rich, there really is no reason to be so negative about the prospects for model flying. It really sounds like you have been got at by the mongers of doom. There are no signs that the CAA are trying to push us out of the skies just ensure we can share it safely. I fully believe that pragmatic solutions will be found that will have the minimum effect on our activities. Especially if we complete consultations in large numbers. Stop listening to the doom mongers who are doing more damage to our sport than anything the CAA can dream up.

  3. Further to my comment above the Boomerang is staying. Had a lovely morning flying during which an instructor flew the B schedule with the Boomerang also demonstrating perfectly straight consecutive rolls. Reinforced how important the person on the sticks is.👍

  5. Do you not have a telemetry log of the voltage during the flight? That would give you a better idea of what is happening than a "battery resting voltage". If the voltage is dropping when you stir the sticks, that tells me that the power supply is inadequate for the applied load, and the purpose of a voltage alarm is to warn you of that situation. Trying to hide the on load voltage drop sounds an odd way to proceed to me. Dick

  8. John, £80 might not be much to some John but to some of us on a tight budget its one more cost. Most of my fleet are second or third hand or other modellers cast offs. Still to fit out my fleet would cost about £1200 at £80 Each. A not small amount for me and i suspect many other people.

  12. The video was the the first trial. The linkage is not in its final state. My FX707 does not have significant polyhedral. Really only dihedral tips. I have several planes with such a layout with ailerons only in the outer wing section and in some cases flown with no rudder either. the last bit of 'improvement' is the trailing edge. The FX707 TE at 3mm is far better than the 6mm edge of the Lidl chuck glider. It can however still be improved to 1mm with LW-PLA printed "extensions". The extensions add 3g in total. It also increases the size of the aileron by 40%. Like most of the aerodynamic improvements I doubt it will be noticeable except it might allow my FX707 to fly on slightly less power.

  13. I bought this earlier this year at a bring and buy to fix up as the Wayfarer was a great design that flies really well, the kits fetch a premium now and this one was going very cheap. This will be a re model as well as a re cover as i have some mods in mind 😜. Hopefully it will look a bit different and eye catching once done, power will be supplied by an NGH 9cc petrol, another used purchase that i have been looking to use in an airframe, it drops in here nicely so off to the LMS on Monday for a suitable mount. This will have to be a quick turnaround as i am hoping to fly it this Friday at the RAFMAA fly in.

  14. The other problem is that with many gliders, especially moulded ones, available space in the fuselage is taken up with the receiver, battery and servos. Fitting a SkyID would be impossible. Another possible problem is the installation of such a device within a carbon fuselage? I can't see any antenna in the image of the Spektrum offering so unless I'm mistaken how could it transmit through CF?

  15. Well done Toto. You've just discovered RTFM does have its uses! However, not all Tx manuals are as easy to understand. I have had a number of programming problems resolved by asking on forums how you do certain things. Thankfully, I always got advice from a chap who used to try out his suggestions before telling me what to do! He is, in my book, an absolute star!

  17. It's nothing to do with money per se. Even if all this nonsense cost 1p or was free it would still be wrong. And it's not unique. I draw your attention to the other current fiasco masquerading behind falsehoods, misrepresentation and dodgy data in the outer London Boroughs - not touching that subject though.

  18. Indeed - it gets my goat when I read that "it will only be £50-100 for one of these gizmos to be added to a model", so it's np big deal..

  19. Before you fly it, run the numbers on eCalc or similar to see it you are over amping anything. It only takes 5-10 mins, and may save you making an error which costs you a motor and/or ESC.

  24. Tag "A Trainer" is misleading, it'll do all manner of aeros, and teach you stuff that you have to work at to do nicely, too valueable a model to consign to the hanger.

  25. Not a Spektrum user, but everyone I know who buddies using the latest version uses the wireless method. It seems to work well; I would stick to that if I were you, as it seemed relatively straightforward to setup when I saw it done at the field.

  26. …and governments start disincentivising the ICE alternatives. Make no mistake, governments globally are going to increase taxes on fuel in the next 10 years to move people towards zero tailpipe emission vehicles and recover lost tax £s from the VED taxes that EVs and some hybrids have historically avoided.

  27. Next down to the other end. With the rudder servo at neutral I connected the wires to the rudder where most of the further required adjustment will take place. I re-covered the hole cut in the white film behind the the canopy as hopefully I won't need to get behind it again. Before I do anything else I will finish off the main undercarriage assembly. I will reinforce the spats internals with glass fibre cloth to help with wear and tear. That's for the next visit.

  28. Here's the correct replacement motor specs page: https://www.aliexpress.com/item/1005002438773237.html?spm=a2g0o.order_detail.order_detail_item.3.1959f19cRGM3oS Unfortunately, the original motor, bought a good while ago, is now in the long grass somewhere off the field! Although I'm pretty sure that it would have been the same dims- I have another couple sitting around in the workshop, all the same size. I'll see how it goes on the field, in a couple of days time.

  29. Probably not your calipers, bolt threads are usually made a little under the nominal size to ensure the nut will go on easily.

  30. There are two low voltage alarms. The receiver will send an alarm immediately when the voltage drops below the set level. Also, the receiver continually sends its measured voltage back to the transmitter and the Tx will sound an alarm when this voltage drops below its (separately) set level. It does sound like your battery is past its best but if you are happy to continue using it, you could lower the Rx alarm (or even turn it off entirely) and then think what you wanted to do with the voltage telemetry in the transmitter. I've never tried to do exactly what you suggest but I'm sure it's possible. Trevor

  31. Oh I don't know. In June this year the SMMT reported that sales were 117,266 vehicles. EV sales were 31700 (There were barely 40,000 EVs in total when I started driving one in 2016) units with a market share of 17.9%. When compared to the same month last year EV sales have grown 39.4%. Significantly the various flavours of hybrid vehicle also performed strongly, so much so that around 100,000 of those vehicles sold use electrons to help propel them to varying degrees . More detailed figures can be found on the SMMT website. Significant things can happen when people start exerting their wallets... idd

  34. Sitting offshore on my nightshift, I have ground my way through this consultation. Despite all the CAA flubber-lubber-lubber, in end it's quite simple for most of the questions to say "Does not apply to model aircraft operated within pilot line of sight". I did think that the BMFA responses were trying to sit between two stools of traditional model aircraft and FPV "drones". Since my own response was purely from the perspective of traditional model aircraft, it was relatively easy to be blunt and straight to the point. I did find the FPVUK response to be a useful contrast to the BMFA one and between the two enabled me to clarify my thoughts.

  37. As a matter of fact, the UK Government owns the sky. There is no such thing as "common sky" as there is with common land. You do not own the sky above your house. The CAA administers the rules for the civil use of UK Airspace. The UK military is responsible for the use of the airspace above designated ranges. As Matty has pointed out many times, the reason for all this activity goes back many years to when the EU, of which we were then a member, realised the very significant economic bdnefits that could flow from the opportunity presented by unmanned air vehicles. The military have been the early adopters of unmanned vehicles covering land, sea and air environments. Even they have not been allowed to fly UAVs outside military ranges in the UK. As an example, when Global Hawk (a very large jet powered reconnaissance platform, carrying radar and electro-optical sensors, with a 30 hour endurance) is allowed to take off and land, a restricted airspace is put in place to provide segregated airspace containing only this aircraft as it takes off and climbs to 65,000 ft, or descends to land, at which height it only meets other military aircraft - sometimes. Remembee that there are 2 big companies that have a duopoly in the civil aviation market in the above 100 seater airliners - Boeing and Airbus. Russia has tried, and failed, and China is trying to establish itself in this area. The other bigger problem is that there are only 2 big civil engine manufacturers supplying this market, namely GE and Rolls-Royce. Hence, the attractiveness to the EU politicians of a new market with very low entry barriers that the civil use of unmanned aircraft represented. That covers design, manufacture, certification and generation of entirely new types of revenue generating business within the EU to counter others e.g. Israel, USA etc. Examples of such opportunities are: A. Agriculture - monitoring crop health quickly and easily using airborne sensors B. Building surveys C. Emergency service use for providing persistent reconnaissance over an area of interest to greatly extend the limited manned aircraft capability D. Pipeline and transmission line surveys - currently using manned aircraft which is very much more costly than an unmanned semi autonomous craft. E. Generating new business. Compare with how the introduction of mobile telephony enabled new businesses to begin. An example here is the huge increase in producing film and TV programmes with aerial sequences that would have been too expensive to include using manned aircraft. We should not think that all of what is being proposed is of little or no benefit to us as citizens of this country. Furthermore, it is disingenuous to suggest that the powers that be have made up their mind. The purpose of consultation is to find out what people think of broad proposals. I doubt there are many in every level of government who have any knowledge of our sport/hobby of flying model aircraft. This is our opportunity to put our views forward. Previously, we surprised government with the number and forcefulness of our responses. We should do so again. Time is running out to get your responses in so please make the effort to do so.

  38. At my old club we had a short stirling flight engineer give us a chat once. He was telling us about how the engineer had no seat, just a 3 legged wooden stool to sit on. on one occasion he was trundling back from a mission when the rear gunner screamed 'BANDIT! corkscrew left!!'. The next thing he knew he was looking at the 3 legged wooden stool he was once sat on as it floated past his face, and a moment later his head hit the canopy. No sooner had this happened he was back on the floor an unable to get up. He then explained that a corkscrew is a big forward shove on the controls with left/right aileron applied, and then a sharp pull up with opposite turn applied to hopefully cause the enemy fighter to whizz by. Apparently the Stirling was excellent at this as it had a high wing loading. Halifax and Lancaster bombers did the same if attacked when out of formation so the BBMF's style is not exactly showing the full potential of the aircraft. Equally, inverted passes just look daft with a WWII bomber and i would rather the BBMF take it easy given they arent actually being attacked by a night fighter. In the case of a WWII fighter i work on the basis that negative G and inverted flight is out, as are spins and other violent manoeuvers. The biggest killer for scale in my experience is speed. Seeing a tiger moth or sopwith pup at warp speed just looks ridiculous. I saw the prop hanging flybaby video and just clicked off it. IF you want to prophang, by a 3d model. The flybaby in question was a lovely model, but it was over powered and to me just looked silly. I know it takes all sorts, but that wasnt for me.

  39. The wing is now un one piece abd bolts onto the fuselage using the 3 bolts supplied. All the plastic fitting for the tail & fin have been removed. It wil be simpy glued on. Like this with only one aileron .servo it weighs 180g. 8g for the two other servos. Motor. prop, ESC, Rx & battery for 60g? It is going to be a sruggle.
