I did tried the hobby wing SCT setup as well but found it too heavy really. Plus with the longer motor found chassis balance L/R was an issue. I do prefer the 540 4.5 - 5.5t setup to be honest. Car feels more balanced and is better to drive. True to have to watch your gearing to avoid getting too hot but that really isn't an issue.

true true true. that is a major issue that igored to much. finally not that its winter im going to try and set it up correctly. a little annoyed that serpent is so expensive and its seems there arent many places to get replacement parts for my 747e. prolly shouldnt had hit that curb at 70mph:weird:

Not a huge amount. Just the new bits from the 748 gas car such as the new 'TQ' diffs. The motor mount arrangement, centre pulleys and the way the top deck connects makes the 748e flex in a more uniform manner. I had the 747e which was a conversion from the previous seasons gas car and now a fresh build 748e and the 748e is definitely a better car than the 747e.

well... i guess i should had waited

What parts do you need? Remember that all the transmission and suspension components are the same across the 747, 747e, 748 and 748e.

I know the feeling but hey the car is fantastic fun and nothing stopping you running the car against others on practice days. Thats what I do and have a blast doing it!

I ran foam tires last ourtdoor season on my Eryx, it was much more fun than running rubber tires. This season I will run a 748e outdoor, no racing but I can bugg my Nitro friends :sneaky:

I really like the durability aspect with big bearings. In the steering knuckels 10x15 instead of 5x10 and 2.5x8x12 on the eryx. Downside is the extra weight, will be interesting what will happen with the laptimes compared with the Eryx and foams on my hometrack

Remember you run 30mm wide rears 26mm wide fronts on the 748. On the ERYX you would have been running 26mm front and rear. My guess is with the same motor/esc on 2s the ERYX would probably be faster over a lap but more difficult to drive on the limit. The 748e is just more fun and easier to drive fast.

My kyosho rrr wheel fit 30mm on the rear same with ellegi tires. Minimal rubbing. Both on the Eryx 3.0.

What's the offset on those wheels?

Based on the concave I want to say -2 max bit they all fit otherwise. The boxes arent marked. Ill check the wheels...

They arent marked you want me to post pics? Maybe you can tell if they are offset or not?

dan_vector 01-23-2016 06:40 AM

No it's ok just curious. Must be different than the usual wheels/tires we run on the car and so because the offset would be different it would also affect the track width of the car as well.

Wheres the gear chart I cannot find it? Does it come with a spur? If not can I use my spurs from my Eryx?

It comes with a 48dp/75t spur which is the same fitment/type as the 411.

The internal ratio is the same as the 747e so you can use this calculator on the serpent site.
