Glad you liked it. It's a great HPR rocket, and one that I recommend for level-1 certification. It's also light enough to fly on G motors when you don't have a waiver.
I did my L1 with an Apogee Zephyr, which is a bit heavier. The nice thing about the LOC-IV is that it's light enough to fly on F or G engines without a waiver.
How stable will the rocket be when launched after all the added tnuts, especially the one at the end of the motor mount? It seems like it would interfere with the mass distribution, since there is only one between two fins and none between the other two. Wouldn't the rocket be heavy on one side than the other, which means it will be more tilted to one side when launched? and finally, what is the purpose of all the screws and tnuts? Thank you for your videos, they are very detailed and helpful!
Good question. None of the nuts have very much mass compared to the rocket as a whole. The nut on the centering ring is for the motor retainer. The other two screws and nuts are for the rail buttons, which guide the rocket along a launch rail. They serve the same purpose as the launch lug(s) on a smaller rocket. None of them significantly alter the flight characteristics of the rocket.
So I have a question: lets say we configure it the way you did, we would put the parachute in the shock cord tube right? Wouldn't that prevent/change the ejection charge? An added bonus with this method is that we can have a big electronics bay, but isn't riveting the nose cone a hassle if you want to take out your electronics after a flight? One last thing: can you add a link were you bought the black rivets from, I want to see from up close how they look. Thanks for the video by the way it really helps.
There wouldn't be a change to the ejection charge. At ejection, the rocket would separate at the coupler rather than blowing of the nose cone. The electronics bay can be configured in several ways, depending mainly upon the sled used to hold the electronics. Rivets are just one way to hold the coupler in place. According to the instructions, the nose cone can be friction-fit in place with some masking tape.
Thanks for this build series! I just ordered mine to hopefully get it ready in time for the club launch next month!

Watching again as my LOC IV arrives this week and I was wondering what size swivel you had gotten. Thanks!
As I recall, it was a 200 kg test ball bearing swivel.
@@REAR_rockets Thank you!
Nice build. I did my L1 with one.

@@REAR_rockets Thank you! I didn't know that there were other options for model rockets other than launch lug, now I know.

Here are the rivets that I used in the video smile.amazon.com/gp/product/B07RFM2VRQ/. Apogee Components also sells them in smaller quantities.
@@REAR_rockets Thanks for the information
What keeps the rocket engine from going all the way up the tube?
Hi power motors have a built in retaining ring on the aft end.
do you have a link to the rivets? amazon is bringing up so many weird options haha

@@REAR_rockets man, i love you! We have a flight april 15th a d i own the loc iv rocket. Im tryong to do dual deploy with it.
Have you flown the loc 4 ??? , Any video?
Not yet. Probably in late March.
@@REAR_rockets Sweet, be sure to get video. Ive built 2 of these, one without the extra section, and one stock, with mirage paint.
Best of luck.
bruh this was posted 1 hour after part 2
It's true. Originally, part 2 was a single, larger file, but I decided to split it.
