Sounds good to me JD but getting it done would spark off the 2nd civil war!Most tunnel racers around here call the classes 20 tunnel, 40 tunnel and 60 tunnel anyway.
Not sure why the ABC's are thrown in there.

Carl,
The IMPBA adopted the letters from the old airplane free flight days. However unlike free flight there is no 1/4A or 1/2A in model boating… We just started off with A.
Also just for a quick clarification.. and this is important at least for now is that we call it Sport 21 Tunnel.. I have had guys confused by saying Sport 20 tunnel. They hear Sport 20 and sometimes not the tunnel.. Can you see the confusion.. Minor.. I agree.
Because i have followed this format for a long time (im a nut for the old aircraft stuff) IMPBAs system, as nutty as it seems, makes since to me. How NAMBA moved the displacements –vrs- numbers up a engine size is a mystery to me. Im sure someone knows more about this then me.
If it were up to me i would dump the old lettering system for a new easer to understand prospective for the new boater.
12 Tunnel
20 Tunnel
40 Tunnel
60-80 Tunnel, Hydro, Mono whatever... you get the point.
25 gas hydro.. whatever the gas dudes need is cool with me.
for FE it would be
8 cell hydro or maybe 10 volt Hydro..
12 cell hydro, mono, sport hydro and the like. I feel that in a few years.. maybe now.. brushed motors will be a thing of the past anyway.. so to heck with motor call out. Want a spec class.. have at it. call it LSH.. or O as they do now and leave as is..
GMC,
You are right there is no STOCK anything in the IMPBA.. just stock appearing..

What are your thoughts concerning making the 40 & 60 sport tunnel a recognized IMPBA class at time trial events?
