Hmmm
Always a problem, especially with a clean aircraft like the T-34 ( nothing to disguise the bits as, no cowl cooling flaps to hide them under ) All these bits need to be easy to get to. I had a similar issue with a trike scale aircraft and ended up sticking everything up in the nose wheel bay. Works ok but you need a table to set the plane up on ( and you need the room not to foul the nose wheel!! ) Other suggestions is to hide it all in the cockpit ( would require sliding canopy for easy access though ) or behind a scale inspection panel ( not much good if you have finished the plane! )
If the fuselage is solid you could build a fibreglass panel to hide it all behind ( use iron on covering as a release agent to get a perfectly contoured hatch )
All the best and good luck
