Modding the Romisen RC-A4

Hi I already ordered the Romisen RC-A4 II at Shinningbeam and was wondering if I can get a regular Romisen RC-A4 and upgrade the driver and Led to something that would be comparable to the Jetbeam Jet-I. Is there a dropin for this model ?

additional info ...

I dont really need the modes of the Jet-I, I just need the light to be as bright or brighter than the Jet-I, Is this even possible ?

Welcome qguy! I don't have any experience with Romisens, but I believe the Jetbeams are programmable to any output level (IBS). You won't find a driver like that, at least with more than 1 mode. DX has a 1-mode driver that can be set, but I don't know that I see the point. However Tido is working on something that may allow the driver itself to be reprogrammed to allow a user to set modes, but it will take some special equipment (or getting someone to do it for you).

Thanks for the welcome !!!. I dont really need the modes of the Jet-I, I just need the light to be as bright or brighter than the Jet-I, Is this even possible ?
