I put the modded needles in my GX-3R. Gives a wider tuning window, so you can adjust 1/8 of a turn at a time on the top as opposed to a screwdriver blade width. I am so used to the small adjustments on my three motors now I think I actually prefer it that way, but the new needles work fine.
The modded head button seemed to give the 3R more snap and a crisper bottom end, plus a little more on top too (could be my imagination
) but it's running stronger than before. No noticable increase in economy that I can tell, but we are running in a dust bowl at present with humid changable weather, so it's hard to tell on economy.
The head button would be a good addition to the MG66 Matt.

GO EFRA 2072 for sure. We have guys running the 7 Port with 2072 in their Mugen MBX6 truggies here, and they are very strong.
Just out of interest, we are selling quite a few 2072 pipes to the guys running the new orange headed Alpha motors here. It It improves the performance of the motors markedly over other pipes they have been using, and still gives great economy.
