Hey everyone! This is my first post on an airsoft forum, and I just had a couple questions. I am sort of a noob when it comes to internal gearbox upgrades. I recently bought an ICS Par MK3 from Evike, and am looking to upgrade it for CQB use. Most of the CQB fields around me don't allow for full auto, so I am looking for something with great trigger response, at about 360-370 fps. I will also be using an 11.1v LiPo. So far, these are the only upgrades I have done. - ZCI Balanced Motor with SHS pinion (http://www.brillarmo...products_id=188) - JBU m100 Spring (https://www.hobbytro...ated.html#35155) - Madbull Ultimate Ball Bearing Spring Guide (http://www.evike.com/products/38825/) I am looking to add a Gate Titan Mosfet (also looked at BTC Spectre and Chimera but these seem to be impossible to get), and possibly SHS or ZCI high-speed gear set (13:1 or 16:1). Is paying ~$150 worth it for a mosfet? Would something like a Nukefet work better? Also, will the ICS split gearbox fit the Titan and 13:1 gears without modification? and is the 16:1 gearset even worth upgrading from the stock 18:1 ICS gearset? I will be correcting AOE, reshimming, and attaching deans connectors to just about everything. My budget for the gearbox is about $200 including a mosfet, and I will be doing accuracy/ compression upgrades in the near future. Any suggestions/inputs would be greatly appreciated. Thank you!
