The Rx8 will not likely be released in the next few months. It will be ready and being tested, but the housing mold will take 8-10 weeks and has not been started. We have our molds built right here in Idaho and mold the parts here as well.

The R1pro and Rspro are rated to 3s because of the BEC limits. The units actually work fine up to 5s or even 6s if you use a seperate BEC unit. WE added voltage cutoffs for these batteries in the latest software. Remember they were designed for 1/10 scale, but because they have such a huge pile of fets they have found a home in larger scales using higher voltages. With better heat removal they may continue to be a popular choice.

I hear you Lutach and agree in some engineering respects. However the Rx8 uses 30v fets and will only be rated to 6s batteries. We are fairly confident that any racing rules will be based on 4s batteries and that will be the standard. Some may use up to 6s, but beyond that there are other factors to consider like the chargers that are commonly available. All of the manufacurers appear to be headed towards this range. If you want decent prices and good racing we have to settle somewhere common. It is not up to use and this just where it looks like we are going as a industry.

We have also had many people suggest we leave the switching BEC out of the unit. Just like rockcrawling applications, it may make sense to keep the BEC seperate since it is a common failure point and kills the entire speedo. This allows easy changes on failed BEC units. Right now we do have a switching BEC in the design. The RSpro and R1pro do not have a switching BEC and fill the other market niche. We think we have it covered and now just have to get them on the shelf.

I know what you're saying. I just wish the industry actually knew the benefits of higher voltage. I can easily have a 10S or even a 12S set up that will have the same amount of power and run time as a 4S set up, but I'll be safer due to less AMPs used. Every thing will perform at a higher level of efficiency. I might be asking for too much, but is there any way you can make me a 10 or 12S capable ESC?

Sweet, might have to try out a R1 Pro then. Im using a Ext. BEC with a MMM now, don't really mind using one on a R1 Pro. Will be using it with 5S. Have you had many issues with the R1 Pro with Ext. BEC?

Dude no prob from me or many others using an external bec , just remember to put a 35v capacitor on it too . I'm running 5s and this little speedy is awesome , no fan either .

Sweet, thanks for the info. Where did you get the capacitor from? I searched online shops but couldn't find any.

I got the 35v 2700uf cap with the esc and just solded it to the battery terminal posts ( bought the esc used in great condition like new ) . You can also get them on ebay in the US but shipping at around $10 - $12 is nearly ten times more than the value of the capacitors , and don't go any more than 3000uf as they are very large at that size .


I also got a couple of 35v caps from Jay Car which i'm sure are located OZ wide, in case i get another Tekin .They are only 1000uf though so if using them you will have to parallel two of them to get 2000uf , i think you should try and run at least 1400uf in our applications .

Here is a link to the ones i got from Jay Car http://www.jaycar.com.au/productView...=&SUBCATID=859 if you find any other sources in OZ just make sure they are radial low esr capacitors .

I got a little circuit board as well when at jay car so if i do parallel two capacitors i can do it on the board and make a little capacitor bank set up

We sell a few good caps also.

TT3543 Power Cap 25V 1800uF 5Slipo (2)
TT3544 Power cap 25v 2200uF 5Slipo (2)
TT3545 Power Cap 25V 2700uF 5Slipo (2)

TT3552 Power Cap 35V 1500uF 6Slipo (2)

Short leads and or 2 in parrallel is always good stuff. Mounted securely, these caps leads were not really designed for the abuse of being bounced around.
