An alternative to loctite grub screw is to use a button M3 hex screw and screw it in reverse so that the threaded part goes into the chassis's front motor mount hole - a bit like a keyed part

Edit - by reverse I meant screw from top down instead

ATM I tend to replace the screw in the top deck. To me it feels like the car as a whole flexes more evenly like this, also the car seems less prone to tweaking now.

Does anyone have a trick to get the coupling off of the plastic spool cups with destroying the cups?

I also run at hobbytown in Fresno. My answer is no you don't want to run carbon brace in your bellcrank it make the chassis front end stiffer. Grip at hobbytown is very un-predictable. You want your car to have more mechanical flex with lower roll center.

The 417 is great, the v5 is also nice. The Raceberry is absolutely not needed for 17.5 (it works for some ofthe team drivers in 4.5 mod though).

I lost the middle top deck screw in a race and it made my car very inconsistent so I always run with the bottom screw out replaced with the grub screw. It seems to give more steering and rear grip on power at the expense of tweaking easier

I'm in the middle of a rebuild and I'm trying to figure out the best place to mount my new Mylaps transponder. Until now I've only had the older PT and just mounted it on top of the servo. Does anyone actually use the mount that comes in the kit? I thought about using it but I wasn't very happy with how far out the transponder sits off the servo.

I mount mine on the v5 servo mount on the centerline of the car. Before that it would just be next to the receiver. You could cut some foam out of the bumper and put it in there if you really wanted to.
