Never use loctite on plastic, it will degrade it.

Believe he is referring to the lower shock cap....

Just ordered a set of GHEA (4) 1.3 pistons. Find it hard to believe the car can get any better for me with these, but figured why not!

LOL

I just weighed my car for the first time last night and I am coming in at 1620g. I noticed that some of you guys mentioned your kits were around 1550g. I am a noob and I am not sure if 70 grams will make that much of a difference. I have made no attempts to put this thing on a diet. Do you guys have any easy fixes to reduce weight? I know this topic has been discussed before but I haven't found any posts for solutions. Here is my setup: Fantom shorty 4500mah, Orion Pro Esc (full length wires), Phantom 3.5 17.5T , savox 1258, airtronics receiver, mylaps, aluminum hubs, aluminum pinion gear.

that's a heavy speedo, espeically with full length wires. A low pro servo will save about 10-12 grams.

When I moved from a full sized lipo to a shorty, and saved 100 grams, the performance difference on my high traction track was HUGE for 17.5... Felt like I went from a 21.5 to 13.5. 100 grams was dramatic, 70 grams will also feel significant.

you can reduce a lot of weight with a lighter motor (speed passion is the lightest I have), tires with thinner carcass like the tendroids from sweep with open cells, shorter wires titanium buckles, a light esc like tekin, or the juststock from hobbywing, plastic everything as far as possible. I don't really bother much since not that good a driver to exploit it so go with what I have.
Mine is at 1600 or so, hobbywing 120A, savox 1257, orion 6.5, IP shorty 4600, sanwa receiver, amb, titanium buckles, front m4 suburbs with aka red, rear ss impacts red aka inserts.

don't own it but its numbers are ridiculous, and heard good things..

if your not looking to drop another $120 for more power than you need, this will fit the bill perfectly..

go for the radiopost. I have the savox lo pro and its not a good idea without a servo saver. Stripped it on a light tap. I just go with the titanium geared ones now.
