I think they are being released this month, I'm using yoke ones in the meantime and they are great. AE also work well and are very cheap

Craig have you experimented with the raceberry conversion?? If so what are your thoughts. Looking into it that's why I ask.

I agree and understand what you did, I was just looking to for a quick 10-15 minute change in an attempt to gain some more rear chassis flex the night before our last race of the season. Unfortunately our carpet season is done now until this fall and there is no outdoor on road racing around here so the project is shelved for now.

Somewhere I saw your setup using a suspension block shim to secure the lay-shaft bearings. (good idea) I just did not have the time or the right screw to try that exact setup. So I went with a much thinner spacer on the bulkhead that was close to the thickness of 3M foam based servo tape just to see if the rear flex was affected and it definitely was. Far from ideal I know, but it was just a little experiment to try in pre-race practice that would also be quickly reversible before racing started if I did not like the results. But it worked well and I ran it for the races that day with positive results.

I would like to try a greater spacer for more clearance over the motor mount like you did but I also got to ask how much is really needed to feel a difference? Here are my thoughts.....

While at your pit table you can easily twist your chassis by hand and get a 1/4"+ deflection at the extreme chassis corners. While that same twisting torque generates no where near as much deflection in the center of the chassis where the top deck is moving in relation to the motor mount IMO. What I mean is the measurable chassis flex deflection is greater at the outside edges than close to the center line of the chassis. And I don't think the cornering grip forces generate anywhere near 1/4" chassis corner deflection while racing on the track. Thus how much clearance do we really need between the motor mount and the top deck to make a noticeable difference?

For example look at how little clearance there is between the V5 floating servo setup and the outer edges of the chassis plate where deflection would be the greatest. It is not that much so I would conclude that you would need even less between the motor mount and top deck due to being close to the center line of the chassis. Sound like a reasonable assumption?

This fall I will explore more top deck to motor mount clearance to see if the effects are noticeable on the track. One idea is to use a suspension block shim and rather than put a screw vertical into the mount to secure it would be to bend the end of the shim 90 deg and run a screw horizontal into the mount after drilling and tapping a hole into it. The idea is to have less bulk added to the top of the motor mount so the top deck does not need to be raised up so much causing belt rub interference. I have not really explored this idea yet so it may not work.

One thing to note is that I am trying this on my USGT 417x chassis and bulkheads and not on a V5 chassis. If it proves to work well I will transfer the concept to my other cars.

Not disagreeing with what you are trying, good discussion topic and I appreciate your input on your findings narcotiks.

these modifications on the 417x ? I'm eager to try it on my V5 the next practice time..
