Can anyone please tell me the difference between the RA-19 and the RA-22?

Thanks.

Anyone know? Also, what about the RA-18?

Trying to figure out which board I should get to convert an MR-015 to 2.4ghz

Which controller are you using? If you using the new KO Eurus with the RF902 module, then for sure, get the RA-22 board. If you're not, the RA-18 board is fine. If you do install this the RA-22 into a MR-02/15, you'll have to change up the servo motor to the original one (cored, i.e. not coreless).

The difference is that the RA-22 board and it's corresponding transmitter module are faster than the RA-18/KT-18/RF901 module and that you're able to program the reverse delay and use a gyro. The RA-18 board has a inheritant delay between brake and reverse.

Ask me for more details tomorrow at the shop when you come to practice. BTW, I have both boards in stock.

Thanks Shawn. I did notice the servo motors were different but didn't realize about the delay. I'm using a KT-18 and since it's going in a MR-015 which will only be used around the house and not for any racing, i guess the RA-18 will be fine.

When I come by tomorrow, i'll take a look at one

does anyone know when the change from reverse delay RA-18 to RA-22 chassis set was done? looking at purchasing a 599xx chassis set for my son but don't want to bother with the 2.4 board with reverse delay as he will be using reverse a lot.

I can say that all the mr-02ex boards are programmable just like the mr-03. And if you don't have the cable, I can set it up for you with the lowest reverse delay settings as well as the wide throttle neutral setting. (Hin't hint, I have an mr-02ex chassis for sale and have 599xx bodies as well) :)

I bought the USB ICS cable and can bring it with me next weekend if you want me to program it.
