They are, aren't they? Great way to sort of zen out and relax on the builds.

Picked up some sealer for the Baby Bertha fins at Hobby Lobby. Started the E engine mount for that also. Used some extra rings to beef it up, I dont have epoxy and I should have gotten some, but I'm not trying to spend a lot on this, lol! Along with a few more things I grabbed, and then a can of paint at Walmart for the Cherokee-E. I'm gonna use that blue in the future. I was really hoping Hobby Lobby had the Red Nova, but they didnt..

Nice! Epoxy definitely isn't necessary for models like this, a good glue like titebond is all you need (and to be honest, many of my low power models are put together with just plain old Elmer's).

I've been using Elmers Carpenters glue. It seems to work ok. I have some tightbond I found I can use. When I did this a few years back I was using a few different types, but the last time I checked they were all dried up plus I can't get to them anyways. But I started using epoxy on most of the builds. And now I'm going to be paperimg finds like crazy from now on.
I noticed your Crossfire back there. I recently built one

I've never papered fins before. I've got an Antsr coming this week that I thought I'd try it on. Do you use the Avery adhesive labels method? Just stick on, trim, then reinforce the leading edges with thin CA?
I also have a Super Orbital Transport in the stash, but I don't think I'd want THAT to be my first attempt at papering fins.
You can always experiment/practice with scrap pieces of balsa.
I used to use 2 pieces of flat wood, some clamps, and a couple of pieces of waxed paper. The glue will somewhat stick to the waxed paper so I switched to using the thin plastic that you can buy to use as a cutting surface for cutting vegetables.
I cut pieces of paper slightly bigger than the fins. I smear a layer of wood glue on one side of the fin, put a piece of paper on there, squeegee out the excess glue then quickly clamp the fin between the 2 pieces of wood and the plastic. After 30 minutes take the fin out and do the other side, then quickly re-clamp and leave it for 12 hours. After doing all of the fins I'll use a sanding block to clean off the edges. I'll put some wood filler on the edges, maybe touch up any booboos in the paper. This gives a much nicer finish than bare balsa but it isn't perfect, I do it to make the fins stronger and it does a pretty good job of this.
The stick on label paper would be a lot easier and faster, I just worry if it will do as good of a job to strengthen the fins and if it will start to peel off after awhile.

It was my first time too, check out the response by bjphoenix. Also look at YouTube videos. I'm actually admitted to the hospital rn. I'm gonna be trying the label method too when I get home. Some ways to do that, but like said experiment with scrap balsa. Sorry man I'll write more when I feel better.

Thanks, yeah its giving me something to do. Got hurt bad at a job years ago. So itsbrough to find a part time job for a 40 year old guy. Trying to claim full or part time disability is almost impossible. So its giving me a reason to stay sane!

Hey I starting using labels for fins. Did the crossfore last night and it turned out great. Just need to get some CA today at Hobby Lobby for the edges.

Starting that now!! Just did the fins last night..I noticed your Crossfire back there. I recently built one
I label paper (almost) all my fins, and have shown the process many times in my build threads. IMHO it works great and is very easy.
A couple of things I do:
1) After sanding the fins, brush off the heavy dust (I use a paintbrush), and then use some blue tape over the whole fin surface to remove remaining dust. The less dust on the fins, the more securely the label will adhere.
2) I don't trim the paper, I sand it off. The really works the edges of the label paper into the wood. It also works well for curved fins, rounded edge fins, whatever. Then I apply CA to the edges.

I launched it on a B4-4 I think it was? It in the video below if I can get it to post.... But because this was my first time papering fins, I used the glue/water/copy paper method. It worked great just warped the fins slightly. I knew it might be an issue, and its not safe or wouldn't be fun to fly on a E bc its just gonna go crazy. They are 8 bux at Hobby Lobby, if I can get down to get another im gonna, and do the label method for the fins, and also get another Crossfire to fly on a D and E motor. Thats my little goal for the July w9th launch in going too. Ill have tons of pictures and viseo after that day. But this one now is just gonna be a test one, or a shelf queen. But I painted it more and added stickers..

I was never a fan of the Bertha rockets, but my Baby Bertha quickly became a favorite of mine.

My 3rd or so Rocket was a Super Big Bertha when I was 8 or 9 around 1990. Always had ejection issues with it, so that one is my one rocket that I'm always trying to get right, and prob will now with modified parts. But its that one like Nicholas Cages character Memphis Raines in "Gone In 60 Seconds", the GT500 was his unicorn, so thats what SBB is to me. But I bought the other ones to go with the "set", but have a blast with my Baby Bertha E. Only thing is it was my first time papering the fins, long story they warped and its too unsafe to fly, almost lost it on a B4-4. But, I can build another along with a Crossfire to burn on E's. But I dont really care for the Berthas look, but as a 9 years old that rocket was the cool thing I had ever seen, and I built it. Bright Yellow, and the end it was a mix of parts from bad ejections or chute tangles, it was about 2 feet high. Every flight took a few inches off with the bad saw, lol. So its just that for me.

I recently was gifted a 1995 Broadsword kit that was just a renamed Big Bertha, it has a stuffer tube that goes halfway up the rocket to improve ejection. It has 5 flights on it, 4 with an E-12-4 and one on an E-20-7 Composite. One of my more labor involved builds but it's my first rocket bigger than a BT-60.

That's cool!
The trick to using labels is to remove the dust before either with masking tape or a waste label

I'm good with the labels. I sand the fin down a little, then after I put the labels on I use a hairdryer for a bit, then CA on the edges, and paint. I have been doing all the balsa kits like that. Just made one piece Olympus fins with motor tube tabs and slotted tube walls, lol. But here's the High-Flier XL. That fin size about maxed out my 5.5"x.8.5" labels. But they make them 100x tougher and more durable. Longevity is the goal for me. But thanks for the advice!!
