Yes. All the bodies fit the same for the Tekno eBuggy variants. The .4 vehicle just needs a bigger opening cut out up front for the steering mechanism, so if putting the .4 body on a .3 you won't need to cut all of it out up front (though it won't hurt if you do).

thanks!

I know the .3 fits on a .4 with minor trimming so I would assume a .4 fits on a .3 with zero trimming.

They are out of 4 out of the 6 oils I need ;) Hopefully next week.

Pretty decent selection on PT oils here too:
Welcome to LutzRC.com, Ultimate Performance, Exceptional Value

Anyone run the wider 1 or 2mm wheel offsets? Curious if they make a difference in outdoor rougher conditions.

from the Hudy tuning guide:

I just used whatever oils i had for the diffs and shocks. Losi diff and AE shock.

Yeah but I'm out of certain Losi fluids and I want to start using a particular fluid in all my cars instead of doing calculations of what cst means to wt. So if I'm going to do that I might as well switch to the good stuff ;)

yeah there was a heck of a deal on here for PT Racing oils. I use the shock oils myself and AE oils for diffs since PT doesn't go as high as some of my vehicles need.

I've never played around with shock oil or pistons. Never liked silicone oil on my hands, but I want to learn. Tapered pistons increases shock shaft speed depending which way it's facing. What is the benefit of this and how does it translate to handling? If the tapered side is facing up how does quick compression affect handling? How about quicker rebound handling effects?

Flat pistons don't move the shaft as quickly, which makes the car's handling more consistent. I'm not sure if I'm asking the right question, but is there a drawback to that? Are you giving up speed for consistency in corners or landing?

If I'm using 500cst in the rear with tapered pistons should I go down in oil if changing to flat pistons with same amount of holes and size? Being that flat pistons move slower does that mean more resistance as if you're using thicker oil then tapered?

There are aftermarket pistons with different features, one having o rings on the piston to affect shaft speed, another with balls, and some made of brass. Number of holes and sizes are all different. Where do you start with oil? Is it just trial and error?

When do you switch springs for softer or stiffer? What are the handling changes to softer and stiffer springs.

Reading about it and watching Adam Drake YouTube videos. I'm now also interested in knowing the benefits of progressive springs compared to low frequency springs. Seems like progressive springs would be a nice option. Newb opinion from someone who just read a few things in a few minutes. For those with real experience with types of springs, I'd like to hear your say.

Man, you are asking for an encycopedia of shock info. It has been covered in many places. Get ready for some heavy reading that will ultimatley leave you with more questions. Really, the only way to know what works best is to test it.

Thank all the factory and team guys who help us start in a good place without having to spend thousands of dollars and months of track time to get something close.

Start your reading here, great visual aids as in video:
Tapered versus Flat Shock Pistons ? What is the difference?

Then get lost in this one:

There is a ton of info to read and learn about shocks, springs, pistions, oil and even more if you want to get deep into shock angles. Its RC school for life if you like to learn and experiment. Takes a long time to get shock smart and there is no denying that suspention is near the top in handling advantages right after tire science :nod:

thanks for the material. Already read the first link before posting questions. Well if it's gonna be tons of trial and error, I'm not gonna try aftermarket pistons and tons of oil. Maybe I'll just get some 500, 550 and 600 oil to mess around with on flat pistons. Gotta change oil anyway. But I really want to try some progressive springs. Anyone know any that fits on these big tekno shocks? Isn't low frequency best for high speed grippy tracks?

If only I had the patience time and money.

Quick little lap around my local basher track. think i might need to go 7-7-5 in the diff's harder compound tire with a more spaced out pin.
