I've gone outside the box different times successfully....... but .......1) .The RK proto 2 Triplex info calls for ,minimum of O42 curves . Anybody have one running on O31s ? I don't have any trouble with the RK Mallets or the RK Challenger.
2 ) Does the RK proto 2 Triplex have a dreaded 5 volt board ? 😨
I run mostly proto 3s with my MTH engines and have slightly modified steamers for shorter drawbar use......... but I've seen issues with the proto 2 5v boards according to guys on the forum. 🤔
Like the RK Triplex even though the Premier is absolutely amazing , but alas , I'd have to start removing exterior walls on the house if I wanted to run the Premier version. 😭
