BAM* Need Transmision Advice on T-Maxx 2.5 BL Conversion
*Born Again Maxxer, I have a structurally-blinged out 2.5 maxx that's been shelved for 15+ years, UE towers, Ti skids, one UE bulk, the other is also metal/nice, MIP CVDs, 3.3 engine upgrade, etc. I was rebuilding the trans, which went poorly (one of the main reasons it got put aside for so long!), so I ordered a new 2.5 transmission, but as time went by, I forgot I did that, so in my head, I didn't have a new/unused one, I had one that needed rebuilding
I've just jumped back in almost as impulsively as I did back in 2005-6; did a good amount of research before ordering parts, including a new 3.3 forward-only transmission, which sounded great; instead of having to finish that rebuild of my ancient 2.5 tranny AND buy/install a FOC kit in the process, I'd have everything I need, all built, for $60! What a deal...until I then saw I HAD a new/perfect2.5 transmission & saw problems ahead when I really looked at the 3.3 tranny I got on Friday...
TRANSMISSION...I now have TWO new ones, but need to turn them into ONE that works...
That prompts another question, I plan on using 2 or maybe 3 cells for casual use, when I want to go at it hard, do I want to run ONE, 4 cell battery, or two, 2-cell ones? the HW Max8 ESC arrived set up for 2 batteries. I kinda like the idea buying a bunch of 2-cell packs and combining them, but I dunno the pros & cons when compared to single 4-cell setup.
Thanks in advance for your help & advice!

- the output shaft on 3.3 tranny is larger than 2.5, so MIPs wont fit. First idea I have is to bore out the MIP's female end to 6mm with a carbide drill bit/drill press. I'm guessing they're heardened, but do you think this will work? Otherwise, does MIP sell new drive-joints (not "cups", right?) with 6mm holes that WON'T change the overall length? I don't want to buy new cvds...they're super $$ on the used marked
- If that's all 2 much of a hassle, can I open up both trannies & take the output shaft/gear from the 2.5 and just drop it in the 3.3, eazy-peazy? And/or, can I take any of the gears out of the 3.3 and move them to the 2.5 in a way that converts it to forward-only without having to buy any $$ parts? I'd rather use the grey 3.3 tranny, as I just installed a FullForce threaded-inserts into the mounting holes, but I'd be OK taking parts from the 3.3 and using the 2.5, if I can do it without spending another $50-100 on an FOC kit.
- the brake calipers are spaced a little wider on the 3.3, maybe 2mm., so my brake plates/shoes won't fit; I have an original RRP brake setup It has the single-post aluminum brake-post, and I think my old one fits fine, it's just the shoes & backing plates that don't fit. Seems odd that they changed the 'spread' by such a small amount, as I THINK my old disc will be good even if I get bigger shoes, but I'm OK getting a new brake kit if needed. which one is best/toughest for brushless conversions?
That prompts another question, I plan on using 2 or maybe 3 cells for casual use, when I want to go at it hard, do I want to run ONE, 4 cell battery, or two, 2-cell ones? the HW Max8 ESC arrived set up for 2 batteries.
