Not sure when kits will have these in them.

Hey guys, I have my LHS trying to locate these new diffs for me. Are we getting closer to a release date? I'm going to the Vegas race next month and I would love to get some run time before I get there.

Coming Soon......

Specialized RC will be releasing a LIPO adapter tray for the RDX Phi to accept batteries larger than 4000mah. Pictured with the SMC 5000mah LIPO and has room to spare. We have easily put the SMC 5000, Checkpoint 5400, Orion 4800 and CORE 5000 in the tray.

The tray also has cutouts to accept the Corally bolt on weights as well to assist with balancing. The production versions will be anodized black. It will be sold as a tray only, weights and battery strap not included. You also have the ability to tape the battery into the tray and eliminate the strap all together.

Estimated street price will be $40.

With the capability of adding 56gr of weight, how much does the plate weight? Doesn't pushing the battery mass outward effect the dynamic weight transfer left to right. Yes, you could achieve static balance using this brace, but I cant see the chassis balancing back out after rolling over the right side. Its my opinion this would cause the car to be loose turning left and push turning right. Plus, wouldn't the plate stiffen the right side? I'm sure you guys did a lot of testing, just tell me I'm wrong and I'll shut up.

Otherwise, what about the diff's?

this tray looks awfull surly specalist rc would be better off altering the height of the bulkheads were the top deck attaches if they made the the motor mount side of the bulkhead carry on the same plain as the top motor screw and lifted the other side of the rear bulkhead up just infront of the layshaft mounting slot to the same height and simply attached the top deck to the top of the front bulkheads that surly would be enough height to get pretty much all lipos under. thats has gotta be a better option than having your cells half hanging out.

I don't exactly see the problem with the tray myself.. The weight is added towards the center of the car. The battery is way off set to balance the car.. It all seems pretty simple to me.. The battery has plenty of protection, and the piece is nicely machined.. Not exactly sure where the awfull thing comes in..

My conversion uses the smc 4000 lipo (who really needs bigger), which tucks nicely under the top deck. IMO the goal is not to displace the weight. If I had a nice milling machine, i would make a batch. But I dont, so I made do. I had a guy with a schumacher think it was pretty cool and wants one made for his mi3.

it looks like they designed it to come out so it wil offset the brushless motor weight since it hangs out far in the rear opposite of the motor. I'll buy 1 of these and a new diff as soon as we get part numbers for them.

76 is as small as you can go before you can no longer see the bottoms of the teeth.

I agree it looks like that was what they wanted to achieve. But I still think this option will only allow the use of bigger lipos, which again is not needed unless you are bashing in the parking lot.

why would you not want to run a bigger lipo? i run a smc 4000 28c to get best voltage and currrent output, i'd run a 5000 if it would fit.

also i would assume dynamic weight distubition would still be off since the heavy motor hangs out much father from the car centerline, and with the lightweight lipo hanging out its not going to offset the brushless motor.

I running 17.5 novak 69 t / 39-40t (48p) combo can go 72-74 / 41 or even 76 /42

40t pinions up can only get mesh to 75% spur to clear motor mount screws.

Smc 4000 need to seat out to help balance when using the brushless.

LIPO, regardless the size you will get 7.2vą and your resistance can very but not that much. Your mah size just means a bigger package which gives you more run time. The average I've been seeing is 5 minutes per 1,000mah. (5 minute races!)

Drifter73, I'm really keen to see your solution. Would it be possible to get a picture? It'd be much appreciated. I'm battling with how to solve this weight problem myself at the moment for an SMC 4000, haven't come up with a good solution, and I can't picture what you have described.

TIA,
Nick.
