Cardboy Posted December 5, 2020 Posted December 5, 2020 (edited) I have made a stud less version of the classic 8865 Test Car Instructions can now be downloaded free here I would like some feedback and your opinions. I have tried to keep as many features from the original as possible including the clunky 3 speed gear box. The parts I'm least sure on is the engine also the front grill I have only used parts which have been produced by Lego in those colours which limits some design choices. I would love to have 63869 in red seeing as the Lamborghini got some in lime hoping there may be some in the new Ferrari. The front wishbones are only in grey now and you cant place the shocks in the same place so it now has a more positive rake. The original had more off road tiers and there rims are hard to get in white but it looked closer to the original than the the new ones for the current 1:8 scale cars. Some of the Blue parts are very expensive so i don't know if i should include some alternative colour schemes or can AFOLs figure it out themselves . (i don't have all the needed colour parts to build it but i substituted some of the blue for dark grey whilst working on it) One thing i have noticed building it from new beams compared to my original its a lot lighter but has more flex in the chassis the suspension is still light enough that its not to much of an issue. Here are some close ups of the engine Edited January 14, 2021 by Cardboy Instructions Added Quote
Zerobricks Posted December 5, 2020 Posted December 5, 2020 Well done, except for the steering linkage. Surely you could use thinner 5L suspension arms to squeeze the front suspension tighter, so that the steering links can be parallel to the arms? Looking at the model now it looks so simple and empty, but back than it was the pinnacle of Lego Technic. Makes you wonder where Technic will be some 30 years from now... Quote
konryd Posted December 5, 2020 Posted December 5, 2020 Looks great! Really captured the spirit! Quote

I though about using them but the original uses double wishbones so felt that this should have the same. The original also has a much longer arms on the hub which also give better clearance for the front shocks. My original design extended the hubs and made them more parallel but these rub on the chosen tiers it's OK if you use a larger rim but there not in white and more of a road tread. Quote

Not quite sure due to the angle. It's something that does need sorting, the steering can't be left with bump steer. Really it wants the steering links attached close to the hub, otherwise you lose a lot of steering angle. How about just using one hard spring on the front of the wishbone? If you're not putting the strut inside the wishbones, why not put a 5L liftarm in there to brace them together? Lose the two thin liftarms as they can limit steering angle a bit. Could be a pair of 5L thins with axle holes at the ends to help retain the shocks. Quote
Jurss Posted December 5, 2020 Posted December 5, 2020 Why You didn't used original wishbones? Those are proper technic ones. Quote
SNIPE Posted December 5, 2020 Posted December 5, 2020 Simply perfect, and instantly recognisable Quote

I thought about it and will probably add them as a alternative in the instructions but as the parts haven't been in production for 20+ years i wanted to make a version that some who doesn't have the 8865 can experience what it was like.

trekman Posted December 7, 2020 Posted December 7, 2020 I think you really need to use the original black pins, for the full 8865 experience - especially when dismantling.... Quote

NOOOOOOOO !!! I still have nightmares about those things I remember all the Lego instructions which had how to build a tool to remove them. Quote
Cardboy Posted December 7, 2020 Author Posted December 7, 2020 So I have modified the steering to remove the bump steer. To make it fit with the rim I had to use some un Lego like techniques. and rotate the track rods 90 degrees. I have given a lot of rough treatment but it survives. Quote

Well done and you gave it Ackermann geometry. I think a 13L gear rack would fit exactly in there without the need of other bricks. Quote
howitzer Posted December 7, 2020 Posted December 7, 2020 Wow, this is great. I just might have to build the original and this version (if you upload the building instructions) and compare them side by side. I even have the horrible original friction pins boxed away somewhere, though maybe I'll skip those... I think it's a good choice to make use of only such parts that are actually in production currently. For the steering linkage, Ackermann geometry is really important feature, as the original had it too as a major upgrade from the previous car chassis sets. Not sure about the wheels and tyres, considering that I don't think there's anything currently in production that would match the originals even remotely. Quote

amorti Posted December 7, 2020 Posted December 7, 2020 (edited) Well done sir, hat's off! If it doesn't collide with anything else, the shocks will be better held by a 5L axle with stop, and two half bushes in the other end. I think one of these guys could hold the ball joint more securely with fewer pieces. Not sure if it would collide anywhere though. https://www.bricklink.com/v2/catalog/catalogitem.page?P=63869 Edited December 7, 2020 by amorti Quote
Zerobricks Posted December 7, 2020 Posted December 7, 2020 Another suggestion iIf you have issues with the steeering arm coliding with the shock abosrbers, replace the suspension arms with 5L ones + thin fliftarms to get 6L and move the shock absorbers a stud deeper. Quote
