Hi Kirknik,

My Duellist is a taildragger and uses those Hobbico mechanicals for the main gear. Tail wheel is not retractable.
I put my retracts in the nacelles, retracting rearwards. This increased the distance between the mains considerably, helps with ground handling.
Note that with the Hobbico units you could easily be operating them at/near their max rated model weight, which considerably increases the wear/tear on the pivots, bushings and limit stops. I use 1-1/2" long 5/32" music wire to connect Robart Robo-Struts to the retracts. The 1-1/2" long wire is easy to replace when they get bent on those heavy handed landings.

Cheers,
