I have always had a hankering to build a DH1 or 2 as their shape is unusual and suited to electric flight. After some searching I found an ARF model made by LX Models . Their standard DH1 model has a 76cm wingspan, but I managed to source a 1.0m beastie from a model shop in HK. They apparently make a 1.3m model but I couldn't find one anywhere. The LX website is pretty toxic and they never answered my e-mails. I must say I am very impressed with the quality of the model. The only gripe I have is that some of the linkages were a bit basic and attachment methods would not have lasted five minutes in flight. Just replaced them with some quality hardware.
Off and on it took me three months to build the DH1, the most time I have ever invested in a model so I was rather relieved when she just climbed away on the maiden flight as though it was the hundredth flight.
It flies brilliantly with excellent control responses. With 4 ailerons and the tail controls right in the slipstream she is very agile. Does nice loops but is a bit reluctant to roll - more likely a technique I will have to learn. It does pretty well though as I guess the original was never designed to roll at all.
