ICS Par MK3 CQB Upgrades

Recommended Posts

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.brillarmory.com/index.php?main_page=product_info&cPath=39_65&products_id=188)

- JBU m100 Spring (https://www.hobbytron.com/JBUM100MetalSpringHeatTreated.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? 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!

Your mechbox will not work well with any MOSFET. ICS is 2 off of a standard AEG V2 mechbox.

 

You picked a platform that is not easily upgraded.

 

I would just keep it simple.

 

Inline SSR MOSFET outside of the mechbox. 16:1 gears is fine on a 11.1V will give you sufficient trigger response.

I specifically chose the ICS split gearbox because I heard it was easy to upgrade :/... Are there other mosfets that replace the trigger contacts that would fit? I'm new to mosfets and would like one that I could just drop in. And is the upgrade from 18:1 to 16:1 gears worth it?

You were mislead. The only easy upgrades you can do are:

 

Spring

Gears

 

I have been in Airsoft for 2 decades and ICS has never had broad industry support for upgrades.

 

Do you need to swap from 18 to 16:1...no you don't and you will not really notice it.

 

There is no drop in MOSFET for your AEG. This is due in fact to the lower volume sales of ICS units.

 

Just recently another user tried to drop a Titan into an ICS mechbox and it did not work until he ditched the cut off lever.

+1 for inline mosfet. Move the wires from outside the buffer tube to inside to run larger gauge, use a battery bag on stock. Keeping stock gears would be best, just use your present motor and 11.1 battery. Since your are cqb, 100 spring should be perfect. Just do the mods listed in Airborne101's signature.

Thank you both so much! Would something like a Nanofet drop in work? (http://www.brillarmory.com/index.php?main_page=product_info&cPath=48&products_id=183)

And is the Nukefet any different? (http://www.brillarmory.com/index.php?main_page=product_info&cPath=48&products_id=516)

I also heard that the ASCU mosfets fit well, but the reviews seem very mixed. Any experience with these? I'm really looking for something that I won't have to solder, and could just drop in. Thank you!

If you can get hold of a GATE MERF 3.2 or Warfet, you'll get most of the features of the Titan, but it doesn't replace the trigger contacts so it should be compatible.

Would these fit in a buffer tube? Ideally I want something that would fit inside the buffer, and leave enough room for an 11.1, but an external battery is fine as long as the mosfet itself would fit in the buffertube.
