Hi, I thinks it's a good idea to start a thread dedicated to tip, tricks and mods for the B4 and B4.1 Here are some thing I'v don't to my B4.1 to make maintenance easier: I changed the screws to the bigger ones, I'v stripped several of the standard ones.. Also changed these so it's easier to loosen the bleu aluminum shock mounts. After the first races I ran, I managed to strip the standard screws so I changed them out for bigger ones I found these cva boots on ebay. I think they are still selling these. I bought the B44.1 ones, you get 3 pair and pay less then if you would buy 3x B4.1 cva boots.. (This only fit's the B4.1..) And I recently done this mod to the wing. I had these spare wingmounts that I bought 2-3 years when I ran a B4. Since I don't break them, I done a little mod Cut the little thing were the clip goes off. Make the mount flat, I'v done this with a knife, you could use a file also. Take you bodyreamer or a drill and make a hole where the screw will go. Make new threads with the screw. If you do this also with the other mount you'll get something like this: Use a little shim or a countersunk washer to make it look even better! I hope you likes my little tricks/mods Don't forget to add yours too!
