RE: Dragon Lady ARC
The fellow in England was using a Zenoah for power - since the gassers are much heavier than glow, some lead in the tail is usually necessary. Those servo covers I have seen before in the English model mags - an internet search didn't turn up anything, but you might email the editor of the article and see where they may be available. My ARC instructions show lightening cut-outs in the wing ( about 6" square ) - if you have older instructions that don't show lightening holes, just PM me and I'll mail you what I have.
