Hello. It is clear that by 1400´ bow was all but obsolete in Czech. The "call to arms" of the city of Slany, which was really backwood outskirts at the time lists sometimes "boge" as something what crossbowmen brought as the secondary weapon. Hovewer serious bowshooting was pretty much dead platform by 1375 in czech lands and everybody used crossbows, for various factors, mostly rise of cities in power and lesser demands in training of militia in crossbow skills in comparition to bow and also fact that warfare in czech has been always "fortress" warfare, something for which crossbow is better. I havent found any mention of husites using bows, only crossbows and very wide use of early guns. There is only one, single remark of "bows" in "Husites chronicle" by Vavřinec z Březové - in comparition to description of crossbowmen, which is on every second line.
This hovever would told you anybody on Czech LH forums like livinghistory or Brodec.
If you want to reenact Czech bowman, you have to go back to days of Czech duchy, there is plenty of archery description in Cosmas and off course, there were battles in which Czech archers played rather significant role in defeating the frankish (read german) heavy armored knights. (At the time in mailie). (See batle of Brudek, battle of Lodenice and various descriptions of skirmishers using bows with great effect.) Also there is well known depiction of Czech archers by Peter de Ebulo (Siege of Miland) where Czech fought for emperror Friedrich Barbarossa (which secured kingship for Vratislav I.). Those archers are typically early medieval archers, no helmet or armour, but big recurved bows (whcih remind me for some reasons finnish/russian all wood composites).
(On related note there are also bawarian crossbowmen, with simple crossbows, clearly "better" units as the wear helmets.)

There is graphic depiction of heros death in Cosmas, which one of my friends has penchant of citing quite often : "....and thus noble warrior Dětříšek z Buzů made heavy onset on the enemy, forward in the ranks, untill he stood alone, bodies massing left and right, flailing his sword as a lion. Thus they shot him with bows, many a bowmen, but he fought very valiantly until, full of arrows, image of a hedgehog died in midst of enemies."
