|Thread: De Havilland Airco DH2 scratch build|
wings all covered, struts painted. Foam cowl ready for finishing and painting. Undercarriage built, just need to paint. Not true scale wheels but ive had these hand made spokes for years so going to use them
decided to fit servos into lower wing. Having asked a few others who went for the scale cable route, the general feeling there was quite a lot of 'play' which I thought in a bigger madel would only be increased.. Dry fitted for fit before covering and gluing. Things are looking ok so far. Gluing all the bits together is going to be a bit of a task though. Next step - constructing the elevator and rudder links and undercarriage
Thank you Roy for going to the effort of photographing and detailing. Some ambitious rigging there. I too was contemplating two mini servos in the bottom wing and I guess while I am at this stage of building would be better to decide now. If you started building this again is that what you would do? thanks Martin
Hi Jeff why turn the tank around? Surely the pipes need to face the engine??
fitted and plumbed fuel tank. Nice and secure. Add 1/32 ply fuzz deck and engine mount. Think im going to put a Saito 62FA now rather than 82 which may be overkill and there isn't much to this plane in terms of structure and weight. Trial fitted Wing Commander Mallard. I know what you may be thinking but he was given to me by my mother in law just before she passed away 20 years ago. Lovely lady and a fitting tribute.
Hi Roy. Yes I have looked at yours several times. In fact only yesterday was using it as a reference to decide on how I would link the top and bottom ailerons and have decided to go with the pushrods. Wouldn't mind a sketch of your closed loop system if you have the time? A great build Roy but the difference with me is I have to fly them. I've crashed a few scratch builds on maidens but at least I got to see them fly and its character building/ You should take the leap of faith. What's the worst that could happen? ok you may crash her but the second one will take only 200 hours!!!
Thanks Jeff. Have a had a look at those plans but not being a brilliant plan reader still cant make sense of them. Need to study them more me thinks.
have made a start on the top wings now. These plans are rudder only but I am adding ailerons so have added the aileron spars. Now looking at my options on how I will link them to a servo. Would like to use the method used on the full size but seems a bit complex. If anyone knows any links or have some suggestions please let me know
I'll bear that in mind Wingman. The plan was to leave a nice hollow cowl so can be filled with as much lead as I need. One advantage of a rear engine. Will be interesting to see how much I'll need but I do have a nice powerful FA 82 so should be ok.So despite a chest infection, the shivers and a cold I soldiered on and fitted the engine mount to the firewall, glued in place reinforced it and cut out the fuselage top from 1/32 ply. That doesn't seem to quite overlap enough so will have to cut a new, slightly wider one. Feeling rough now so called it a night
Have added 1/32 ply doublers for added strength and to reinforce the cabane struts. Joined the two sides. will glue rear firewall once I've drilled and fixed the engine mount. Have cut hole in middle former for fuel tank and started to construct the elevator control assembly (bottom right)

Thanks Jeff2wings and Colin. Will make references to those plans too. Have already started with some modifications. Got the elevators, fin and rudder done today and cut the three main fuse forms. The rear one from 1/4" ply which will be the firewall for the engine mount. This will sit further forwards through to allow for length of the crank. Dry fitting at the moment. picking up the courage to start gluing.
Interesting, thanks for that Colin. Quite a lot of modifying to do on this. New firewall to support the engine, adding ailerons etc. I don't hang around when I build so you wont have to wait months for completion. will keep the updates coming
Started on the fuse. cut slots for cabane struts and glued in place with a sheet ply doubler to strengthen. Will be adding strength through the build as this was designed for electric power but I will be using a hefty Saito 80FS. Thankfully managed to get in touch with Mike Roach who designed this for some handy tips. Thanks Mike
