I recently purchased a resin Honda RA300 shell from PreWing with the idea that it might form the basis of my entry in the upcoming GPde2013 Proxy. It is a lovely representation of one of my favourite early 3-litre F1 cars as driven by one of my favourite drivers, John Surtees, to victory at Monza in 1967. My building skills may not be at the same level as some of the fine craftsmen on this forum, but after 5 seasons competing in the VRAA proxy, I am not unfamiliar with building resin-bodied F1 cars. However, this one presents some interesting challenges. To begin with, I am going to need the full 2 mm latitude allowed by the rules in the scale wheelbase measurement to centre the front axle in the molded rocker arm gap and have the rear axle properly located aft of the rear bulkhead. And then there is the gearbox... ... it's a lovely representation of the Honda transaxle, but there's no way to fit a crown gear in there. I am hoping the exhaust piping will sufficiently hide the crown when viewed from above. Underneath, the engine area will need a lot of Dremel-work to remove enough resin so than even a slimcan FF-050 motor will fit. In fact, I don't think a BWA bracket is ever going to fit unless the lower half of the bulkhead and engine are removed. I fear I will have to come up with another solution to locate the rear axle. As they used to say: Bulletins as they become available... Old23

I think you'll find that Ranch design gears will fit.

I brought a PPL version and that is about the same amount too long. The extra lenght is in front of the screen, so it looks like I will have to remove 2mm and recast it the correct lenght.

I think you'll find that Ranch design gears will fit. Yes, thanks for the suggestion. Mark was kind enough to send me link to Mel's Honda RA300 build thread on Slot Forum about a year ago. Very clever fitment of the RD crown inside the resin transaxle. However, the chassis I plan to build will have the motor offset downwards for a lower CG (and hopefully better performance), so I plan to use a somewhat larger diameter Slot.it crown gear. I guess I will just continue to muddle through to a solution. Phil, unfortunately I do not share your skills at casting a revised body so I will live with the slight overscale wheelbase and carry on.
