Oh good lord, see I've got a handful of military aircraft books, - complete breakdown schematic, & a decent amount of WW2 fighter (osprey) books...& Ya there's quite a few models of it.i was talking about the defined panel lines of the tail feathers, I've seen many styles on how to achieve that, I want a strong,light, & as scale look as possible, it's a mk9-- super marine pica kit, old,old... Directions are giving me a rough time,...Even though I dry fit, & read, re-read, and read again, I still manage to assemble something wrong, & in the booklet drawing it's right, blueprint, different story,... I know the cg is also been revised, oh ya...This has maple motor mounts which extend from (almost cockpit former) about 3.5" from cowl, to cockpit... Unsure if going electric/gas/nitro...Appears to balance the fuse out when installed, if not, way tail heavy, & I lightened it, ... Good Lord
