I hope there will be enough stability in the screw tightness to keep the 2 servos steady. For sure this is a lighter car than 747. The world championships track needs a light car with.tons of flex and tons of center of gravity. A lot more 747 option parts before are now stock 748 parts which is good like the super short rcm shocks! Wow to that!and lowered shock towers.

Recieverbox and extension wire holder was just a masterclass!!

Lowfriction belts are now stock parts in the 748 according to the manual! Haven't checked the actual kit.

I wonder when the new diffs will be ready.
We had issues with the mono engine mount on the 747 cracking here in the uk. So I'm quite pleased the 748 has 2 separate mounts for the engine!

Typo.. Serpent has the wrong tooth count for 2nd gear spurs listed on the 748 setup sheets. I 'm glad they now have clutch info on the setup sheet. I'm headed to the dungeon to begin my build.

Pass you soon...

Looking good! Stupid question, do you put your own foams on those wheels?

Most racers including myself set their ride height and track width with bare wheels. Those are normal foam wheels that have been shaved down to nothing.

Looked at the manual and only change I dont really like is the way the rear of the front upper arm mount. From what it looks like, it mounts right to the upperdeck and can easily break in a hard crash. Still loving the car though. Especially the rear flex system.

Ok, every time I use blank rims to set ride height, the rear ends up 3mm higher.
I just use the qualifier size which in my case is 58/60 and set it with those and very rarely touch it. What do you set the rear at if the front is set to 1mm on blank rims

No. These are wheels that i have used in a race. Soaked then in acetone to remove the excess foam (nice and cleanly). The advantage of this is setting the track width is easier, also fitting the car into the scrutinisers box for maximum width is easier. Testing ride height is also a trick. I don't set my ride height using these tyres although i check to make sure that if i run out of tyres i have around 1-2mm ride height front and back at the most extreme.
The main reason i have these is for weight purpose. If i weigh the car with just the rims and i end up on 1650g (current weight limit) i know that after the final i will be over with minimal foam on the rim. Basically worse case i have no foam on any tyre the car will still be on the weight limit.
