Try and get the longest screws you can in those new bad boys then
If people are running big Lipo (5000mah) and want to get the same weight balance as Ellis, Phil and the rest of us it's pretty hard to acheive it without getting the total weight over 1700g. If you're running say the TP3200 which is as light as a feather then to get the same balance it can be acheived with much less overall weight, it's then up to you if you want to add weight at front and rear to try same balance but different total weight.
