The pulse set is hors de combat I'm afraid so it's Hitec 555 and micro servo for me.
To make up for this modern junk I'm putting in I'm going to cover it with REAL SILK on the wings and stab with colored jap tissue for the fuselage
I'd forgotten that I bought some packs of silk a few years back for an Old Timer gassie....
Ah..... the aroma of butyrate.....
