[k25], 8 inches of draw, great seal. Shoot ~270 fps with the barrel shown below, 240 with a 8 dart hopper.
Supa Leet 3-stage optimal barrel.
~7 inches of tight CPVC, ~8 inches of looser CPVC, ~4 inches of PETG. Total length of ~19 inches.

Great seal, just some excess friction from the catch. Only around 200 fps, should be able to increase that with some filing and sanding of the catch and support plates, but nothing is certain.
Handle for my next rainbow, it is rather unique so I thought it deserved posting.
Polycarbonate is flush with the wood for optimal smoothness on the handle, i.e. no plates sticking out into my hand. The plates also make for the installation of a 1/4 inch wide trigger easier, eliminating the need for spacers.

Unfortunately, both companies seems to be having some problems with quality and customer service.
I completely agree.
In my opinion, I would go for Hobby Mods' kit. It contains all the necessary parts for a basic mod, and a fantastic platform to build off of, all at a great price. The tutorials for installation are also very helpful, being detailed and informative.

I bought this kit for the retaliator and the catch and plunger assembly doesn't seem to have any damage.
Can the Catch move freely? Also, Is the prime-length correct and and is is pushing the plunger all the way back to meet the catch?

2. Pictures would help. Otherwise we have little idea of the issue
3. I would open the blaster remove the spring, and then prime the blaster and manually push the plunger to find out where the system is failing.

Do you have the significant knowledge, experience, and ingenuity to pull off an integration? If not, practise putting weird shit onto nerf shells and making look pretty. I did this a few times and it made my first integration go and look smoothly. Also, read up on how to paint nerf blasters. I recommend following this guide to the letter. It works really well.
Also, for the pvc barrel that goes through the crossfire bow, use a piece of pipe with a large I.D. I recommend 3/4 cpvc, 1 pvc, 3/4 thinwall pvc, or something around that size.
#346960 Aluminum Flywheels

Here are a few things I would do to the flywheels to make them even better. A) I would look into putting knurling or some type of texture on the flywheels to get better grip on the darts. Knurling may be overkill, so something finer may be a little better.
I would take out as much weight as possible. Maybe drilling holes on the top of top of the wheel or thinning them out. Aluminum is light, but it won't compare to plastic, and even the plastic wheels are a little heavy.

The best thing you can do to solve the issue of flawed darts is to make stefan darts. Some people ban those types of darts due to safety concerns, but honestly they are perfectly safe. Stefan darts are very constant and accurate, if made well.
Since you were asking about mods, I will add my suggestions. As I previously stated, most accuracy (or lack therein), stems from the darts. Mods can help, though. If you are using flywheel blasters I recommend brassing the flywheels. Many people say this is bad and is detrimental to performance, but I had no such experience when I performed the mod on my stryfe. For springers, not much can be done. Extending the effective barrel in high volume springers can add a little amount of accuracy.

The FPS readings sound right to me. Nitefinders with extended draw and spring replacements can achieve similar performance.
Good point, I also forgot that he is using elite darts, those are little lighter and more air efficient in terms of initial fps. I guess that is pretty much what this is anyways.

Those fps readings are impressive...not sure I can trust them though. Amazing mod if those numbers are accurate. Could definitely rival some homemade blasters.

If you actually need an answer, i can say that if it is plugged and run at high pressure, a 3k will be able to handle a hopper. You are much better off running a BRISC however.

My stryfe shoots 50-70ft flat with 2 imr and full rewire. With that many AA you might as well jump to imr you will go through that many AA while playing.
Did you even see what he said? Imr's cost 14 euro's where he lives for just a pack of 2. Then you also have to add a special charger to that.
I recommended 8 AA's because they are cheap and accessible. In Addition, the current from 8 AA"s is greater than 2 Imr's, which will lead to greater performance and less damage to the motors.

I'd definitely go with the retaliator, but I can't find them in stores anymore. Are they discontinued or something?
No, they just have a different paint scheme. They are white now. Your store may also just not carry them.

Also, I would coat the flywheels in something. What I do is wrap them tightly in electrical tape in direction that the flywheels spin. After the wrap, I use a hair dryer on the highest setting to warm up the electrical tape. It is crucial that the tape is wrapped in a way that when the flywheels spin, the seam that the tape makes is not able to be peeled back.

bullshit
post the insides and video proof of 650fps or its an empty shell and youve never made a blaster to shoot more than stock
Look up Southern Brisbane Nerf Group on youtube and watch some of their videos. Aussies know how nerf.
That is entirely possible to, I have seen first hand singled titans or hydro cannons shoot about 450 fps, and at almost half that pressure. The tank in that blaster must be massive to produce those kinds of velocities.
But for the sake of the topic, I have been wondering what the pump is being used in the blaster that you made. My local bicycle shop only carries some weirdly sized pumps or something. Great work so far, can't wait to see it in semi-auto.

#346616 Integration?

For most of the shell-to-shell contact, you will want to use solvent weld (pvc cement, the all purpose stuff (red can)), in conjunction with a solid liquid epoxy. The cement should go only where plastic touches other plastic, and the epoxy should go everywhere else on the bond. JB weld, aroldite or any other epoxy that works well with plastics will be fine. To add structural stability I would add some epoxy putty, or adhere some polycarbonate or metal bolts between the connection. This will do the majority of the structural support. To make the bond smooth and clean, use a dent filler thing called Bondo. This is used in auto restoration and repair to take out dents and such and is easily sanded and smoothed. Be careful to avoid over application of the Bondo, as it will take awhile to sand.

Yes, it does. If you are using the same darts (same mass and cross sectional area / air resistance), firing from the same angle at the same height, the average range should directly correlate to muzzle velocity.
Yes, but only if you are using the same darts. If you are using different darts, as one would with a stryfe compared to a plusbow, they could be totally different. That is why I said it. If you are using a plusbow and a stryfe with elite darts, the plusbow should shoot farther.

"Flywheels are theoretically (per the physics) a horribly inefficient and expensive means to get 300FPS to the point such a thing is an absurdity.
They are a stopgap, dirty, inelegant, "cheater" device that just happens to work out well for superstock, and nothing more.
The 120-150fps cap for superstock has a number of contributing factors. Accuracy of darts is one, but many of the darts become inaccurate well above or below that. Safety is another. Flywheel velocity ceiling is another." -Walker Finn,
What must be understood is that fps does not directly correlate with range. I have modified stryfe (rm2 motor replacement, rewiring, electrical taped flywheels) that fires at around 100 fps. This being said, it outranges one of my overhauled nite finders (they shoot around 150 fps) by an appreciable margin. This guy has a very shallow understanding of the physics of Nerf, something that I am not all that knowledgable in too, but I would still say that he is wrong to an extent. Also, people always complain about the accuracy of flywheelers, just please go buy some of these darts. I have plugged them a few times before, and I can say that they are some of the cheapest, best performing darts for flywheelers you will ever encounter.
I wonder how a double-action HAMP with twin detachable-reverse-extended-choppers would fare against a flywheeler...
Flywheelers and HAMP's are pretty similar. Short range, extremely high capacity, fantastic rate of fire.

First off, for me to use a flywheel blaster against someone using a snapbow or a ESLT, I would need copious amounts of darts and clips, and a comfortable way of carrying those things. The necessity for ammo is greater for a flywheel blaster than a hoppered blaster because of its use on the field. A stryfe or rayven would be used as a rushing primary. The accurate range on a flywheel blaster is really going to top out at 70-80 feet, while a snapbow's is about 100-110. The rate of fire on a stryfe is about 2 darts a second, about 3-4 times that of a snapbow or plusbow.
What also must be considered is the ammo a stryfe and other flywheelers use. Most of the ammo that you will find at an NIC event is slug darts. These darts, regardless of their much shorter length, do not fire well out of flywheels due to the felt used to pad the front. Strands of fibre can get caught up in the flywheels and seriously fuck them up. If you are going to use a flywheeler, you will have to provide almost all of the ammo it will chew through. That being said, buying a couple hundred china knock-off darts is going to be about the same price as an equal amount of slugs.
I think putting all of my knowledge into writing has helped me come to a conclusion. In my opinion, there is absolutely nothing wrong with using a stryfe or rayven in an NIC game. Rushing strategies are very useful against people with low rate of fire blasters, and a rapidstrike or a stryfe is about as optimal as you can get in rushing blasters. Ammo for a stryfe is cheap, and most likely you already have a stash of elite darts and clips that you have subconsciously collected over the years. If you are one to take pot shots, don't use a flywheel, but for most everyone else, as long as you don't mind running, pick up a stryfe and some koosh darts and have fun.

#346240 Stryfe Barrel Extension

I did these videos the week Containment Crew uploaded his.
All my brass was internally polished, as well as beveled inside the magwell for feeding.
He never came back with his promised formal testing, so I did it for him.
Although the goal was to measure accuracy and precision, like I tried to do with the shitty fence and cardboard, I also took chronograph readings. Long brass stryfe was ~80fps, short barrel ~95fps, No barrel 123.7fps. Any effect you see on accuracy and precision is due to decreased muzzle velocities taking the Elite dart back into an operable speed.
The simple fix is to use koosh darts, watching the video you can clearly see a much tighter grouping of the green koosh darts, even though most of them went high and right over the fence. I also had to get closer to the target by 20ft with the brass stryfe to even collect any kind of data at all, which skews the results.
Kewsh is love, Kewsh is life.
Thanks for the data.
As for the koosh I have bought some and I love them, but I found these darts to work just good if not even better. The foam is pretty fat, about as fat as the fatter beige hot rod xl foam. This is actually a great thing because it means the flywheels grip the dart much better. In addition, the foam is consistent, and so is the head to foam connection. These darts are also mad cheap. 20 bucks plus 5 for shipping?!?! From China?!?!

Brass Stryfe is a terrible idea, it adds so much friction on the darts.
While I do agree with you that a brass barrel will add extra friction, I think that your setup imparted way to much unnecessary friction. I have yet to try this but I would imagine that a shorter barrel would add extra accuracy without as much range decrease.

I think he is doing it vice versa.I don't think this will work very well, unless you replace the Firefly plunger with something larger.
If you are doing what I think you are doing, remember to replace the rotating mech. Good Luck!

It is expensive but Xplorer stuff is really high quality. Their longshot kits are truly amazing and I'd love to try out their Xarrett kit (if I could afford it).
Not really, my friend got a longshot fighter kit and it was poorly constructed and offered little performance gain to just some basic longshot modifications. It is good but not worth anywhere near the price they sell it for.

Honestly, I would probably rather read a monthly or weekly publication than reading everything that happens on Nerfhaven during a week or so. Many posts are either total garbage or are just paraphrasing what someone else said. If we could have a publication solely specializing in all of the interesting or constructive things that happen on nerfhaven, it would be much more appealing than nerfhaven itself.

I don't know enough about it to explain it to you properly but I already have some epe foam from a previous order and it is with out a doubt the best foam I have ever used(and I have used a lot of different foam). In my opinion it is better then log home white, hot rod xl beige and sera rod beige/red. The pours are so small that they are barely visible and when flattened it springs back with a little re shaping, it is similar to the consistency of a yoga block
That was a typo, thank you for bringing it to my attention. The foam will be 13mm
Good to know. How does it hold up to high temp hot glue guns?

#345622 Motors for Flywheel Blasters

Over twice that. 11500 rpm*1.25in diameter flywheel*π*(1ft/12in)*(1min/60sec)=63fps. The edge of the flywheel is traveling at 63 feet per second on those motors, so with no dart slip and no loss of speed when firing or anything like that (both of which are present in copious amounts in reality) you top out at 63 feet per second muzzle velocity with those motors.
Like those maths. Thank you for the advice. RM2's are very affordable, but I am always out to save money. I will probably buy these motors ( https://www.pololu.com/product/1592 ). On the website they say "They are a generic alternative the Solarbotics RM2 motors, which have the same form factor and nearly identical performance." I hope these will be good, and I am going to save a couple bucks with is cool.
