Bem,
I've been flying a Super Sicroly 2 from the RCM&E plan, which is an all wood version, the MAN plan is foam wing only. Both are a little different around the nose to the MK plan you show, and all are slightly different in tailplane plan view to Hanno's model as seen in the photos. Mine uses a Webra '10ccm' with muffler and is a very likeable model, not, I think, quite up to Matt's Super Star 2, but close enough to give it a good run. I like it just a little better than Curare as it is not quite as fast, but easier to get along with, it 'feels' slightly more solid in the air. Flaps work well, and will slow the model down very well, but I find a good nose up trim change with flaps down, like Curare in that respect. I have just got back from a good mornings workout with Curare so the feel is from a close relationship with both models. I still prefer Atlas above all of them, but Atlas is from the same time frame as Curare, and really if you want to compare models of the same time frame then Sicroly is up against Superstar, and Superstar is my favourite model of the period. Hard one to beat. I believe that the MAN and RCM&E plans are still available, and I can try to find the magazine articles, if you wish. I have a Sicroly 2 plan here (RCM&E) and it can be copied, if needed.
