Hello Daithi. Thank you for that. Locktite at the high port, Sir! Roy

Yes John, Mine flew last year, albeit very briefly. It is only 3 channel, no wing-warp etc, therefore it was a bit like flying a barge! She is now a 'Hangar Queen'. Happy landings, Roy

Great project, John. If you have a look at my album, it makes my attempt look rather amateurish! Well done. Roy

Hello All. Thank you all for the advice. I failed to mention that I'm using an electric power plant with reversed polarity thus I can use a conventional tractor propeller! I'm not sure if that would affect any of the advice given about thrust lines. Manish, I've used brass sheets from Precision Metals. Size is 0.010 x 4" x 10". The code is SM2. It is available from most model shops, in UK, but I seem to remember that you live abroad! I will upload some photographs over the weekend. Happy landings, Roy

After rather a long delay caused by life, family, hospital and other reasons, work has recommenced on the dH2. Photographic evidence will follow soon! The motor is fitted and works but a question has arisen to which only the combined knowledge of the readership of this blog have the answer! On a normal 'tractor' power plant a measure of down and side thrust is built in. The dH2 has a 'pusher' motor. I have built the firewall as the plan dictates but it doesn't appear to have any down, up or side thrust! Any suggestions? Happy landings, Roy.

Thank you for all the replies. I am using a 16x6 K Series Airscrew, as recommended. I will investigate 'Stinger' and Stuart McKay Models. Happy landings, Roy.

HELP!!!!! I recently bought an Evolution GX2,20 cc, petrol engine. I've run it in as per the instructions and it starts and runs very well indeed. After a bit of surgery to the bulkhead, in order to fit the supplied 'dustbin' exhaust system, I installed it in a Black Horse Chipmunk. My problem is that our club, Barton's Point MFC, quite correctly has a strict noise limit of 80 Decibel. The engine is producing 91!!!!!! I have toyed with many ideas for noise reduction including stuffing the silencer with wire wool, blocking off one of the exhaust pipes' and of course, using less revs! Has any-one got any other ideas? Happy landings, Roy

Great pictures. I will be there next month, as a Standard Bearer, for a memorial parade. I'm looking forward to it, even though I was Army not RAF!

HELP! I have been given a box of old engines which I intend to bring back to life. One is a very old Super Tigre G25, (stop laughing in the cheap seats) which I have managed to strip down. The piston ring broke and one of the 'wrist' pin, (I always knew them as gugdeon pins), circlips flew across the workshop! Does any-one know where I can get some spares, please? Happy Landings, Roy

Very sad news, indeed. His column was always a great read. Condolences to his loved ones.

Cymaz, that film was absolutely wonderful. How did I miss it in TV? I had 'goose bumps' as it took to the air. I would gladly sacrifice 6 months of my life to be involved in the restoration of such a terrific old aircraft. Roy

Now where did I put that Piggy Bank?

I wish you all the very best of luck, mate. Thinking of you and yours!

Hello Folks, I've been a bit slow in building the dH2 recently. The weather was good for flying so time was spent at the field until my Wot 4 lost the battle with gravity! I got the Chipmunk air-worthy and managed to park most of it 40 feet up an oak tree. The bit which came out of the tree was the engine and its fall was broken by landing in a big pile of sheep poo! The remainder was retrieved subsequently and all the 'bright and shiny' bits will be re-cycled. The workshop is getting a bit cold now, but I have purchased another Chipmunk and have now almost finished building it . The defence rests, mi Lud. I have managed a bit of progress on the dH2 however. I have finished the inter-plane struts and trial fitted them. (Note the new Chipmunk, in the background, shielding its eyes from the dH2). In order the secure the struts to each wing, I got one of these, above...................... .........and with the aid of tin snips,a Dremmel, a small file and lots of patience, converted it into lots of these little brackets which would serve to secure the struts and provide anchors for the forth-coming miles of rigging. A fair amount of fiddling, fettling and cussing later and the upper wing was trial fitted. Above is a close-up of how the the brackets, yet to be 'rounded-off' and 'tarted up' a bit, are employed. A small bolt is recessed into the end of each strut and through the bracket into a captive nut in the under-side of the wing. The whole fitment is held in place with the horizontal nut and bolt, which is also yet to be finished off. The aileron control wire along the leading edge is supported and guided by very small loops bought from a model boat builders shop. Above is a, slightly out of focus, picture of progress on the cabane struts. After much huffing and and puffing, not to mention the odd cup of tea and a Biccie, the carbon-fibre aileron 'joiners' are fitted. The ailerons are actuated on a closed-loop system and I'm pleased to report that the servo is 'man enough' to do the job. I'm also most 'chuffed' that the wing incidence is still accurate and the whole structure doesn't show any signs if warping. That's about it for the moment, Chaps. Happy landings, Roy
