Hello all

I'm looking for the shortest possible ignition set up for the DA 50 so I can keep every thing inside a close cowl. Looking around I came across the Rimfire 1/4 32 plugs. Is anyone running these in this engine?
Looked over at CH Ignitions, and he does not recommend this set up. I saw a few threads where some twins were set up this way, but was wondering how a 50R would do. Can anyone tell me how much shorter this set up would be than the stock DA set up with the cm-6 plug? Thanks.
