Re: All Remaining 2020 Events Cancelled

Paul We will be discussing the Binham fly-in's next week and hope to be in a position to confirm details soon. Pos...

Re: All Remaining 2020 Events Cancelled

Hi Dave With Campsites opening on 4th July and flying fields already open and with no restrictions on travel (in England) we have decided that it will be acceptable to run the Ghost Squadron Binham Flying camp 29th July to 5th August. We are going to follow the guidance of the Camping and Caravan Cl...

Re: Convair YF2Y-1 Sea Dart

On the servo side of things we decided to try the large Seiko servos, loads of torque but a little slow. They have a tie bar with a slot, this allows any disparity between the servo matching without loading the servo because they are fighting each other. It also allows movement of the elevon with o...

Re: Interference on electric retracts

I am guessing a dirty commutator on one of the electric retract motors producing sparks which are being picked up by the wiring to the the flap servo causing it to glitch. Take the retract out and in a dark room look to see if you can see any sparking across the commutator.

Re: Storm Petrel XL 200% 108" Wingspan

This is a 500cc fuel tank that I have, should I place a bigger one in for the Zenoah 38cc engine. https://live.staticflickr.com/65535/49886833026_6be5fee84e_c.jpg With a Zenoah 38 in that model, which will not need anything like full power to fly, a 500cc tank will last for ages.

Re: Storm Petrel XL 200% 108" Wingspan

Geoff The Greenley undercarriage is a very simple wire bending job. The top 90 deg bend on the main legs can be assisted with some heat but all the other bends should be done cold to avoid taking the temper out of the wire. I have been bending this type of undercarriages for years with just s simpl...

Re: Storm Petrel XL 200% 108" Wingspan

Hi John, Thank you for your post, will take on board what you have suggested and take another look at the SD Greenley U/C. Because the U/C on the SD Greenley has been tested for years and thousands of landings, makes sence to make the same U/C. Where would it be possible to get a U/C made for this ...

Re: Storm Petrel XL 200% 108" Wingspan

Don't make the undercarriage from Aluminium. It is heavy and will fatigue quickly. It will also need substantial mountings in the fuselage to secure it. Look at the piano wire undercarriages on the SD Greenley http://www.ghostsquadron.co.uk/greenley_downloads_page.html Greenley / Lowley fuz. It is s...

Re: NEXT sport jet by Mirce

Hi David I would seriously reconsider sheeting your wings in 2mm lite ply. I have done this on 2 models (did not learn the lesson on the first one !!) and regretted it on both occasions as the finished wing came out way heavier than sheeting in balsa. The Lite ply is quite a bit heavier than balsa b...

Hi All I have received my Operator ID (Thank you LMA) and in reading all the supporting documentation it does seem to imply that I only need to put my ID on all my models that weigh between 250g and 20kg. It does not seem that I need to put the number on any of my models that weigh over 20kg. Is thi...
