They are different and can not be interchanged

Thank you very much for any input, it is greatly appreciated
I'm in the process of testing these. I've created a jig and am making a spreadsheet. I'm going to be testing a friends avid springs along w/ xgear and losis that I've personally got. From my testing I can tell you thus far that the advertised spring rate between the xgear springs is very small and lower that advertised. The TLR were nearly dead on. I'm only testing at 1/2" and 1" compression, repeating 3 times and averaging them.

oh ok...

i'm really looking forward to racing this weekend. The car is getting better. it amazes me how subtle changes can immediately be felt on track.

i'm looking for new batteries. my Thunder Power shorties aren't up to snuff.. i always thought the brands we close in terms power but i did back to back testing versus a Venom pack and my car was .5-.7/sec faster PER LAP.. it felt like a rocket compared to the TP pack that i just bought in OCT..

i still am not sold on Venom, they cost me a slash in '10 when the back burst into flames (yes it was properly maintained)

what do you guys recommend for shorties besides revtech..

Turnigy nano tech is not bad for the money. I love Revtech though. Losi not so good and reedy just so so. There are lots more coming on the market. Fantom has a nice pack I hear.
