    Now for my gliders I actually like to use a lot more down elevator than up elevator. I use this this kind of differential as I like to get a balanced feel when flying inverted (pushing the elevator stick forward). With this in mind I actually bias the servo arm  to be pointing upward a bit when the elevator is in neutral (centered). I've also found that most gliders need this extra downward elevator when using crow in the landing mode.

    If you had left the servo arm at 90 degrees to the pushrod and installed the servo as the designer seems to have intended, would the offset on the elevator pushrod/hinge not have given you more down than up movement as required. I would not be keen to be the first to jump to Doc Hammond’s defence but in this particular case,,,,

    Mike Shellim at rcsoar.com has created some excellent templates for flying wings and various gliders. There is one for the easyglider power and one for F5j and another for F3f. These are free to download and also come with comprehensive written instructions on how to set them up.

    Thanks for posting the clip of Lou Reed, John. I knew nothing about him. The sum total of my ignorance was evident on Monday when my neighbour, seeing me walking along the path wearing my aviator sun glasses, said I looked like Lou Reed. I just said that I felt like Lou Rolls! I am now much wiser thank you, John.  

    You have such massive and rewarding journey ahead of you.

    Nice job John.

    A couple of, hopefully constructive, oservations.

    Silver is a notoriously difficult colour to see in the air. More orange trim on the wing tip tops and the fuselage will help.

    When you do fly it I imagine that trimming the elevator is going to be interesting with the two bends in the bowden cable and the raked back horn position that will give much more up than down elevator movement.

    You could cure the unequal elevator movement, if it is an issue, by raking the servo arm aft and re centering the elevator.

    If the backlash in the bowden cable proves to be excessive, I would suggest a mini or micro servo in the top of the fin with a short push rod to the elevator.

    Club finder on the BMFA website is your friend. You may find that your nearest slope flying club is at Whitesheet in Wiltshire. There is certainly plenty of expertise at the club to help.

    THESE ARE ACTUAL COMPLAINTS RECEIVED BY "THOMAS COOK VACATIONS" FROM DISSATISFIED CUSTOMERS:


    1. "They should not allow topless sunbathing on the beach. It was very distracting for my husband who just wanted to relax."


    2. "On my holiday to Goa in India, I was disgusted to find that almost every restaurant served curry. I don't like spicy food."


    3. "We went on holiday to Spain and had a problem with the taxi drivers as they were all Spanish."


    4. "We booked an excursion to a water park but no-one told us we had to bring our own swimsuits and towels. We assumed it would be included in the price."


    5. "The beach was too sandy. We had to clean everything when we returned to our room."


    6. "We found the sand was not like the sand in the brochure. Your brochure shows the sand as white but it was more yellow."


    7. "It's lazy of the local shopkeepers in Puerto Vallartato close in the afternoons. I often needed to buy things during 'siesta' time -- this should be banned."


    8. "No-one told us there would be fish in the water. The children were scared."


    9. "Although the brochure said that there was a fully equipped kitchen, there was no egg-slicer in the drawrs."


    10. "I think it should be explained in the brochure that the local convenience store does not sell proper biscuits like custard creams or ginger nuts."


    11. "The roads were uneven and bumpy, so we could not read the local guide book during the bus ride to the resort. Because of this, we were unaware of many things that would have made our holiday more fun."


    12. "It took us nine hours to fly home from Jamaica to England. It took the Americans only three hours to get home. This seems unfair."


    13. "I compared the size of our one-bedroom suite to our friends' three-bedroom and ours was significantly smaller."


    14. "The brochure statd: 'No hairdressers at the resort.' We're trainee hairdressers and we think they knew and made us wait longer for service."


    15. "When we were in Spain, there were too many Spanish people there. The receptionist spoke Spanish, the food was Spanish. No one told us that there would be so many foreigners."


    16. "We had to line up outside to catch the boat and there was no air-conditioning."


    17. "It is your duty as a tour operator to advise us of noisy or unruly guests before we travel."


    18. "I was bitten by a mosquito. The brochure did not mention mosquitoes."


    19. "My fiancée and I requested twin-beds when we booked, but instead we were placed in a room with a king bed. We now hold you responsible and want to be re-reimbursed for the fact that I became pregnant. This would not have happened if you had put us in the room that we booked."

     

    They walk amongst us. Scary is that they vote amongst us. Scarier still is that they drive amongst us too.

    Luna 2m moulded glider set up

    in In The Air

    Posted

    From memory the Luna has a straight trailing edge and a taper on the leading edge. If so 40% of root chord will be a good starting point for CG. Eye ball the AMT parallel with the wing get your mate to launch it and be ready on the elevator stick/trim. A bit of aileron differential will be nessecary with the down going aileron moving somewhere between half to two thirds that of the upgoing aileron. 15mm up 8mm to 10mm down.

    You might want to put something on the BARCS forum.

    Do we overpower our models these days?

    in All Things Model Flying

    Absolutely modern models are over powered. Throttles are the answer. Back in the day when the biggest motor you see at the patch was a Webra 61 I did see one in an MR Hurricane. No flaps or retracts but it did fly well. The tooth pick on the front looked a bit odd though. 
    The prototype PMP Kerfuffle flew well on a MDS 38. Mine had a Irvine 53 with an inch cut off the front of the fuselage sides. Good fun.
