Hi Gents.
Firstly my opinion on engine choice, for what it's worth!
Having had a couple of glow engined twins (Ripmax Harmony being the latest, a low wing fully aerobatic job) I'll have no hesitation in buying 4 SC's for my Halifax. The Harmony has 2 46 two strokes in, and given reasonable maintenance and running in (i ran them in seperatley, on a single engined model to get a few flights under their belts. I intend to do the same with the Halifax's too, although with 4 i can't see me doing it over a weekend as i have previously!) , i've found them reliable. I also, within reason don't panic too much about the engines being perfectly balanced throughout the rev range. i DO use a tacho to check them, but seek a reliable tickover and clean pick up more than the revs being identical throughout the throttle range, and this logic hasn't let me down yet, even when low level knife edging! Reinforcing a point made earlier in the forum, however, my engines will all be sourced new.
However, a question to the more experienced larger model builders about planned servo instalation. does anyone have anyone have initial ideas what to fit? I see the ailerons and elevator use standard size, the rudder and throttle minis. With the weight of the model my experience suggests hi torque digital jobs but realise this isn't the large petrol engined, 3D capable machine i'm used to!
Thanks for your experience!
Ps This will be my first scale multi, so I'll be after flying tips in due course!!!
Best regards, Ian
