Weight reduction.

interesting. Didn't think it would be that different. We have a project in the works where we are going to swap in all these lightweight goodies, I'll have before and after total weights as well as the weights of the individual pieces. I'll link it in here when we publish it.

He took about 25g out. Thats pretty significant.

Yep, cut gears, top shaft and pucks were a huge weight savings on mine as well.

no idea on the weight saving actual number, nor do I overly care. But I was wanting more weight out of the rear of the car. So why not remove it from the tranny. Less weight, faster motor spool up. Quick motor spin up is nice to have on my current track W3. On my old outdoor track, it didnt mater. Also, I recently went from 4000 mah 200g shorties to a 4800mah 220 gram shorty. So I am hoping that moving that weight forward will give me more of what I want from the car. But, jebbus stock is expensive. Sometimes, I think I should just go mod, lol. But 17.5 is a much more fun and competitive class locally. I have no hopes of winning the A Main, but I would like to make the "show" more often, and i need all the tenths I can get.

Is anyone running the AVID thrust in the B5 Pucks? The MIP one went together well and everything was super smooth after diff break in. I am just curious.

I got the Phantom body for the b5m last night I cut out the vents in the back I'm just wondering is anyone else coming out the front windshield for better airflow and cooling on the mid motor and if I do will that had a lot of drag to my car

Well, I would make a hole not a square for the windshield cut out. holes tend to have less cracking, than a square on the corners. Secondly, for ROAR, I think cutting you the windshield is illegal. The cab forward windshield is "supposed" to act like a front wing and help with steering. So... if you have a space practice body and dont mind trying a big hole in it go for it. Lastly, if you run on a dusty or fluffy track, a lot of that debris will come through your front windows, because your front tires will kick it up in there.


IMO, what we really need is a replacement chassis brace that had a mount and cutouts for a fan. No one will make a plastic one, so it probably be delrin or aluminum. I dont know if it could be 3D printed. Someone was making 3D printed ones for the TLR22.

Why get used to a bad setup?

Replace that 4 gear with a 3 gear and put the weight where it needs to be to generate enough grip and all your problems will be solved!

Thanks wildcat. I run at warehouse 3 on damp clay so dust isn't an issue I was more worried about aerodynamics. Do you race at w3?

Wildcat1971

iTrader: (84)

Yeah, I run at w3. I have no idea on your skill elvel and if you will notice a difference in "feel". If you have a spare body, you can always try it. Make sure the air has an Exit. Air comes in and then goes out. How hot are you running at w3 not with a 17.5?

I used to race 8th scale nitro and just got back into rc a few weeks ago. I'm learning electric and 2wd now so my skill still leaves a lot to be desired lol. My rear motor was running 35 degree timing with 33/66 at about 120 degrees. Mid motor same setup got hot so turned timing down to 20 degrees. I'm thinking of picking up a hacker 17.5 motor to replace my trinity fantom 17.5 I hear they are monster stock motors and run cool

Wildcat1971

yeah, I have yet to try the hacker motors. The guys in Phx love them. I normally gain about 20-30 deg running MM on average. IMo a fan is probably what is needed, but AE didnt really put that option into the car. Maybe something someone makes later on. Another local phx driver gave up on MM for 17.5 and just runs his RM in 17.5 and MM in mod. I know Kinwald plans to test 17.5 mm at w3, but he said he will probably run fans. I am sure his mods will be interesting, since they always are. He is the guy that made a custom chassis from a cutting board, lol.

I would love to run mod but i know the only people at w3 that run mod are for the most part very good drivers. I don't really care if i lose but don't wanna get in the way of the faster guys so i think I'm stuck in stock for now. Would love to see a fan mount come out

I got up early this morning to try out my new Wolfpack shorty and a little different setup. I really do like how it drives with the shorty but honestly, I'm still not happy with it - the car is still difficult to drive. Man, my B5RM had so much traction coming on to the straight that it could do wheelies sometimes. B5M, not so much. I actually went so far as to put .5 toe in out back. It's worst coming on to the straight and when off power coasting into sharp turns. Starting to wonder if the MM just isn't for me. The 4wd car on the other hand was a really treat to drive today! I just can't get enough of driving that car!
