  • U and Ux class builds - post your progress here

    This thread is intended to feature U and Ux class builds and their progress to share with others. So don't be too shy to post what and how you're doing.

    I'll start off.

    As usual, my builds begin with the chassis. I got this Ranch Design extruded aluminum chassis intended for 1/43 cars from Retro. It's got a nice adjustable wheelbase feature and was intended for a FF030 motor. I modified it to take a BWA FF050 motor and added 9:27 gears, custom made Ranch Design rims and Paul Gage tires.



    I'm going to try mounting a SCX Fiat 850 Coupe body and see how it runs. I've gone ahead anyways and turned down SCX Fiat Abarth wheels into inserts for the rear and just kept the plastic Abarth rims for the front.



    So far, so good.

    This SCX Fiat Abarth body will fit too.



    Crap, it's 1.96"/50mm wide at the rear flares, just over the 1.93"/49mm limit for U class. It'll get bumped up to Ux.

    Decisions, decisions.

        Nice looking Fiats! I like the #23 850, an elegant modern design, almost a mini version of an Alfa GTV!

        Alexis, who produced the Spider model body?

                Here's a just recently finished Bugeye build, eligible for Ux though I'd be chuffed if the fiddly bits got knocked off and lost during transport and racing.





                The body's on top of my go-to chassis for Bugeye/Mini builds from a Reprotec Fiat Abarth. It's fairly equpped with a Slot It motor and gears, Ranch Design rims, BWA wheel inserts, Paul Gage tires and a Ninco spring guide.



                But, I'm more inclined at this point to go with a Mini for my Ux entry.

                  TF - I don't know how I missed your diorama - looks like a capable crew!

                  Dan - do you have a Sprite in every color yet? Nice work. Lookin forward to the next maximized Mini!

                    A Chassis for a U13 Mini

                    It's time to get serious and do some building for U13.

                    I got out my trusty ceramic building board and started.
                    First the axles had to be pinned in the proper place. This is always the first step, as the axles have to be in the centre of the wheel wells and parallel.

                    I wanted to build this so all the weight was as low as possible, but since the space inside a Mini is minimal, pardon the pun, I also wanted to add as much weight as possible.

                    So I chose 1/8 solid brass rod for the main frame rails. All the other bits and pieces were pinned in place until it looked like this.



                    Since I plan to use small wheels/tires, I wanted the axles to be lower, so it would clear the track ok. I usually just set the axles onto those 1/4 inch square sticks, but this time I notched them so they will sit lower.

                    I copied a BWA motor plate in 1/16 x 1/2 brass, and made the axle mounts out of 1/16 x 1/4. The rear bearing is a brass tube which will be cut out later. The side flanges are 1/16 x 1/4. When I looked at the picture below, I realized that I will have to move them back a pin hole or two.



                    I took my time cutting out the pieces and setting this up, about three hours or so. Tomorrow I plan to solder it together and remove the pins. That should take about a half hour.

                    I will update this project as things progress.

                      Thanks for the pics. I bought one of these blocks ans nails and had yet to use it. I will try it out when re-building my Sprite.

                        Retro,

                        I've penned a notice for all track hosts to reinforce their tracks for increased axle loading due to, ahem, certain cars!

                        I bought one of those perforated ceramic soldering plates for less than $8 based on your previous recommendations: a great value for the money. Thanks for showing your technique!

                          I know, my cars are lead sleds. They may not be the fastest because of it, but everyone comments on how easy they are to drive, eh?

                            Hi JT and all.

                            Just got confirmation my U13 car body is ready so hope to have next week sometime.

                            My entries will therefore be as follows:

                            U13 - Munter Alfa Romeo Barchetta
                            UX13 - Munter Sprint

                            Regards

                            Chas Le Breton

                              Looking for the rear motor/axle mount bracket, that am told is not available anymore. Theer's a brass one at PM, but it really looks heavy duty!

                              Any help would be greatly appreciated. Trying to build my first chassis with help from that super builder JT! I've teamed with JT and his chassis for two proxies now, the Cheetah and Sprite Proxies. His chassis are first rate!
