So guys,
I recently went to Warzone in coventry and took my G&G Firehawk. Which now doesnt resemble a firehawk at all.
Anywho I wasnt happy with the performance, sluggish response, cycling slowly when using 3 round burst - despite having a Perun drop in MOSFET and ETU.
I'll start off my saying this is more of a process diary for me, i think better when I put my thoughts on paper/screen. But and advice/suggestions are more than welcome.
Anywho, I decided to change out the standard gears from 18:1 to 13:1. Probably over kill in hindsight with an ASG boost 40k. Now I'm suspecting this is actually a high speed motor despite Bullseye Country Sport listing it as a high torque. Cause although I'm getting what I want out of the build, the moment I start firing the gun the wires near the battery get hot quickly. Especially at the Tamiya connection. Not burny hot but enough for you to notice it after a couple of shots. After a while the battery will then start to get warm. So somewhere there is resistance and I ent that good with electrics.
The Perun uses low resistance wiring so for it to start getting warm this quick something is up.
The shimming is fine, minimal play with no rubbing and freely rotates numerous rotations when screwed closed and rotated with my finger when testing. Im also using a madbull internal kit, cylinder, cylinder head, piston and nozzle. The piston was tight on the tracks so modified it so it moved freely along the tracks in the gearbox.
The motor sits in the grip quite well although the gearbox hole and pistol grip hole are off centre by a couple of mil. So could be changing the angle it sits on the bevel slightly and creating more friction that standard. Although the motor adjustment adjusted fine with no noticeable grinding or straining. I adjusted till it whined then quarter/half turned it back until it sounded nice.
The battery I used in testing is a Nuprol 7.4v 1300mah stick with 20c single and 52c burst. I forgot to mention the Perun is also fused with a 30a fuse. As wired by Perun.
Not sure on the spring I think its either an m90 or m100 and I havent been able to chrono before or after the build so not sure on fps yet (my brother on law and I share the chrono)
Overall the build turned out how I wanted it to, its snappy, responsive and sounds much better than it did previously and I had a lot of fun putting it together. But I dont want to risk using it until the heating up issue is sorted.
Sorry for the length, thanks for reading did you got this far.
Rob.
