    Has she increased your insurance recently!!

    The matter of the question bank is interesting, but it is only a matter of time before the 20 questions and answers are put onto the interweb. This will allow the answers to be learned verbatim with little or no understanding of the answer, and therein, in my opinion, lies the risk. I am surprised the questions with answers have not yet appeared in this thread. However, if the BMFA see this as a way of keeping the regulations to a minimum and keeping the regulator off our backs then it gets my vote (although I cant see how anyone can monitor the purchase and control of small drone toys)! I do wish to take challenge with Erfolg on his sensationalist take on commercial airliner heights, and perhaps is Heald-Greenism. I live quite close to there, and as commercial pilot flying regularly form Manchester Airport I can assure him that great lengths are made to fly on a constant 3 degree approach to touchdown. This starts from a long way out, and airlines are penalised for flying below the 3 degree approach if below an altitude of 3000ft (approx 2700ft above the threshold at Manchester). So, at 2NM from touchdown the aircraft will be 600 ft above the threshold elevation, and at 7 NM from touchdown it will be about 2100ft above the threshold. Even accounting for the rise of the pennines at about 13 NM from the 23 threshold our height rarely gets below 2000 ft until inside 6.6 NM from the landing threshold. I fly models near Heald Green and our site is limited to 400 ft (as I guess are many). I put a GPS sensor in my plane to see how high that is, and while it is easy to infringe, particularly in vertical manoeuvres, it is not often that ones plane is above this. However, I cant help thinking most small drones (that seem to be the problem) would be impossible to control at that height. Police helicopters seem to transit at about 1000 ft, so unless they are on task I don't really see them as a risk either. Tim

    That looks fantastic, well done. That masking technique looks really interesting, thank you. When you say a flag was reversed do you men that they were all standard flags, and one was not reversed? The protocol for flags on aircraft is that they are like ships flags blowing in a wind form the nose. From the port side they look 'normal, and form the starboard side they look 'reversed'....just checked on tinterweb and that is how 558 is. But perhaps you knew that. Regards Tim

    What a brilliant film. Thank you Ash for posting. I went through flying training with Mark Hanna (sadly also deceased in an aviation accident), and his father, Ray, flew a fly past and display at our graduation parade in1980 at RAF Linton-On-Ouse. He used MH434, it was fantastic then, and it still looks fantastic! Tim

    Actually Josip I don't think the G would be that great as the speed is still quite low. At high speed it is possible to pull to the G limit of the aircraft, but at low speed it is aerodynamically limited (at 4G the stalling speed is twice of what it is at 1G (root 4 = 2), so I don't think he would be able to get that much G On at that point. It looks mightily impressive though (I was there as well on Saturday). Tim

    I think I have rediscovered it. I lost control of my Acrowot today which hit the ground in a near vertical dive. Luckily I wa snot too high and the engine mount has broken. The damage is limited to the engine mount and the cowl (which was pretty tatty anyway!). On investigation back home I found the Spektrum AR6210 orange light would not stay on and the servos were erratic (much like it had been in the air). Spookily, with a new battery pack everything worked fine again, so I reconnected the previous battery pack. Although the voltage read good at 5.67v (96%) the receiver would not work properly when connected to this battery pack, but always worked fine with others. I checked all the connections and sure enough found the black wire corroded at the plug from the battery to the switch harness. I keep my models in the garage and tend to keep them on "trickle" charge with a Ripmax charger, so presumably I hit all the high risk areas for black wire corrosion. If my diagnosis is correct then sadly it hasn't gone away! To be honest I was a little relieved to solve the p[problem, as there is nothing worse in my opinion than not finding the problem, All works fine again after cleaning the connection off, but a new battery pack is on its way anyway (and a new Carbon Copies cowl)!

    Colin I had exactly the same thing the other night. I scoured everywhere, tried different battery and switch combinations all to no avail. Finally I found a thread that suggested I had connected my power source the wrong way around into the receiver. I did not think that is what I had done, but on checking I indeed was connecting the power the wrong way around. If you do this the receiver shows a bright led for a few seconds, then it goes dim when the bind plug is inserted. I reversed it and it bound easily. That may not be your issue, but the advice certainly saved me form throwing away a fully serviceable AR6210! Tim

    Please pass on my condolences to Pete's family. Like many others I have always enjoyed his column. Perhaps RCMandE could package the comments form this thread as a form of condolence book for Janet and the family? Tim Cheal

    Its ironic how our experiences change our perception. As a JP QFI many years ago I would have written that there was always the excitement of the engine surging on the JP! (I had an engine surge in a JP5 once during a reverse stall turn.) I have very little chippy experience, but never had the engine stop! The experience analogy probably applies to a wingover. They are a great way of turning an aircraft around (especially a non aerobatic one), but I suspect we all have a different experience and understanding of what a wingover actually is. Personally, the less defined it is the better, as there are less guidelines to measure it against and I am more likely to get it right! Tim

    Hi Terry I am still flying mine. 22 flights so far. I have had a couple of mishaps, including one attempted landing in quite windy conditions. the wind got under a wing at the last minute, and although I applied full power to go around it hit the ground tip first and cartwheeled. I needed to repair the wing at the root, but otherwise it is running fine, although at the last outing I tipped it over on to its back on landing due to the nose wheel bending back (again). Fixed again, but the nose leg does need seem to need constant attention! Tim

    Thank you guys, Just what I needed. I'll add to my shopping list. Tim

    I have a question regarding Danny Fenton's rivetting (excuse the pun)article on scale detail. Danny, you talk about 'canopy glue'. I tried to buy some canopy glue some time ago from my LMS, assuming it would be good for sticking my canopy on my Acrowot. But they did not know what I meant by canopy glue. So, can you give me a steer to what 'canopy glue' you mean, and can you recommend something specific? With thanks in anticipation. Tim
  16. Tim Cheal
    Sorry to see that Mike. I managed to cartwheel mine the other week (trying to land too slow in gusty conditions) which damaged the wing root and bent the metal spar, but all now back in flying condition! Luckily the nose was not damaged. I am sure the repairs will not take long and you will have it flying again. Tim

    Could you use an electrical connector (the plastic block things with small screws). I have used them to clamp together control wires, but don't see why you couldn't leave three connected for the use you need? Tim

    Great stuff Terry. Well done. Tim

    I am really interested to see what others say, but I use some silicone sealant I got from the local motor shop. I just squeeze a bit around the exhaust when I put it back on. Tim

    Terry That looks great. I really like the instrument panel.I persevered with the spinner supplied, but looking at your aluminium one it does look very nice. I was flying my cub on Friday with an ASP61 2 stroke,and a fellow club member was surprised when he saw it was a 2 stroke. I rarely use full power and he had assumed it was a 4 stroke from the sound! Good luck with the maiden. Tim Edited By Tim Cheal on 20/04/2014 10:07:04

    Thanks for letting us know Colin. Sometimes the small things seem really important (anybody who has raised teenagers may recognize that!). It can be really frustrating when you cant fly because you cant get an instructor, but the satisfaction of knowing you can go to the field and fly alone safely is well worth the wait. I still believe my suggestion is plausible, but back in me box for a few months! Tim

    Hi Colin Sorry I got dragged away earlier. Imagine the wing sitting above the cub with the left wing forward of the perpendicular to the fuselage And the wing has dihedral. As the aircraft accelerates along the line of the undercarriage track (straight ahead for the fuselage) then the aircraft will tend to roll right). As your instructor experienced. This is equally true of the undercarriage is fitted at an angle to the fuselage (and of course the wing). As the weight comes off the fuselage the aircraft is no longer constrained to track along the line of the undercarriage track, and so ‘weathercocks’ to present a more balanced wing profile (in fact the fuselage is now crabbing). Hence the roll stops once airborne. This all may be complete rubbish, but something to consider. Tim
