Kyosho Blizzard BL63 rear cover improved

Well, i just bought this new Blizzard 2.0 from Kyosho and i have to say im pretty shocked what is Kyosho´s todays situation. This is my first Kyosho model that i have bought in over 15 years. The previous was Ultima ST when it came to markets.

First of all, what is that silly gearbox? And what are those single metal bushings? Were are the double ball bearings? And why are those free roller wheels beared with plastic “bearings”? And basically you couldnt use more flimsy plastic with these BL63 parts. 1,5mm thick, without fibers? Is this todays Kyosho, or is this just a their toy-grade model?

So. Here starts the improvement project. If you´ve followed my Ultima ST improvement project, you should know that there will be a lots of improvement here also.

The stock part is 1,5mm thick, with 5mm thickness screw points.

My modded part has 3mm wall thickness, with 8mm to 9mm thick screw points. I will modify the design once i have tested these parts my self (so these first releases will also have room for improvement). This first release will stiffen up the part, but the screw locations will still have the original wall thickness for the outer sides. The inner sides have extra thickness. The V.1.3 will have thicker screw points. Im trying to do it so it doesnt need supports, but it will also mean that the part doesnt fit flush with the chassis side plates. Or then i will need to do a flange to the part if you want the flush fitting rear cover. Give a comment about that!

The flap angle is 45 degrees, so you should not need to support that. Im currently printing my own part from CF/PETG filament.

Enjoy and drop a comment or a make how did it work for you, or if you want any changes to be made!

Also check my other parts that i have made to Ultima ST Racing Sports/Type-R/Evolution chassis.
