One thing that becomes painfully obvious with the unstoppable technological advance is that people are generally speaking crap at taking pictures or video. Congrats man, we can't see anything.

Current camera's in most cell phones or even consumer grade digital cameras do a terrible job filming small/fast objects. Even professional cameras in a static location do a poor job when filming full scale cars on speed runs.

It is easy to be spoiled by the amazing car coverage we see everyday on TV that we easily forget how hard it is do get good video.

I'm running a similar setup but with a 7700kv 4 pole. Would it be worth it to get a NEU motor?

Fastest so far is 119 mph on Turnigy Heavy Duty 4s 5000mah/ 60-120c. I want to go as much faster as possible. Gearing is 52s/43p.

I've been having trouble keeping it straight and under control but I just installed a spool in the rear and it seems to be much more controllable. I will find out this weekend when I test it.

Well if money allows pick up a neu or cordova research. I run 32p gearing myself the 1409 is a strong motor. also if you haven't already pick up a 2 deg rear toe block or 1 deg.

My toe is still stock. So less toe is better? Never knew this. How much did you get your neu motor for?

To help keep the rear stable, you might want a new spoiler that provides some better down force. The one mounted on there now looks to almost want to lift the rear. Also lowering the body overal would help. It seems to be riding kinda high. Look my post up in the USGT forum and see how my McLaren body is mounted.

I don't run a spoiler at all.at this speed too much downforce will cause blowovers.

Thanks for the tips guys. I will being doing some speed runs this weekend and I'll let you guys know how it goes. I will probably stick to my 7700kv motor for a bit longer as I'm pretty sure it can go faster than 119 with it.

So I got the rear solid axle in and I followed the advice from PHILDOGGG and THE PROFESSOR and lowered the body in the front and redid the wing. Thanks again guys! I also added an extra ounce of weight to the front (total 6 oz).

Pretty happy with the results. I did a 123 mph and 124 mph pass today!
