Wow, video number 400!!! When we started this project, I had no idea it would go this far (and long!!). More fit up of the engine cowl. It's a slow process. You just have to take your time and trim little by little. There was some sanding needed on the lower cowl to help with fit, but once it got close, it started to fit right.

I prefer well-made tools from America or Europe also, but agree that for low volume use they can be hard to justify. I bought the really cheap crimp tool from SteinAir for the avionics connector pins, but didn’t really like it as it wasn’t a ratcheting tool and you had to crimp entirely by feel. I debated getting the industry standard DMC tool, but it was close to $700 with tool and positioned. So, I split the difference and got a JReady tool which is essentially a DMC knockoff. It isn’t DMC quality and I am not sure it would do 2,000 terminal, but then I’m doing maybe a couple hundred at most and so far it has worked well. It sets up like the DMC for specific pin sizes and wire gauges and seems pretty solid and accurate and it is a ratcheting tool so has greater consistency than the much cheaper SteinAir tool.
Making good progress there. You are 6-9 months ahead of me. I’m building doors now and doing electrical. I am building my panel from scratch and that is a time consuming process.
No one is going to fault you for using the cheaper tool, especially when it performs the same task. The funny thing is that my dad was a Snap-on guy, and his son is the Harbor Freight guy, and to me, you performed the spark plug wire fitting flawlessly. You could have checked them with an ohms meter to make sure they are at the proper resistance. Good work.
Thanks for the reminder to check the resistance. I was thinking about it when I started but then it slipped my mind 🙂
Great video thanks
Thanks Mike!
Dad and Chad had a similar issue on the same grommets I think. Wires were pulling away inside engine bay. Seems way too tight to me even if you expand the gromet size.
Yeah I haven’t been a fan of how those coils sit so close to the baffle. Would prefer if they were outside of the baffles.
I've said it before, and I'll say it again - you and the Project Manager work together like an Operating Room Team. Inspiring.
Thanks!
The Rans looks great! I continue to be impressed with your team effort!
Thanks! We’re so close to being done!!
I purchased the air box front and it fits perfectly nice and clean follow the instructions like your videos I had same issues with the fasteners what is the tape you used under the cowl in the back?
I contacted Geoff at Aerosport and he said we need to trim about 1.5" off the front of the airbox (our airbox didn't come with any instructions). Even without the seal on the airbox we couldn't get the cowling all the way on. Found a few of the 180 fasteners locally at GAHCo, but ordered a few more 220 and 240 from Rans yesterday. The tape is anti-chafe tape. Has adhesive on one side. I think it might be teflon. We get it from our local EAA chapter.
@ thanks for your reply Geoff and I have been flying buddies for 40 years I have all his mods for the Rans S21 BTW Happy Anniversary
Thanks! We have a good amount of AS items. Don’t have the strut fairings (yet), console, or panel. But everything else has fit great with little to no modification needed.
I guess I didn't see your alternator cooling hose!!?? Just a suggestion that the winged cam locks for the oil filler door save having to have a Phillips screwdriver in your pocket.
Couldn't source the winged studs locally, so will keep it in mind the next time I order from spruce (I hate paying shipping that's 3x the price of the parts!)
@@s-21project92 I understand that feeling. They have been a great, yet small, addition to my RV-8. Besides, you have time.
Dzus Fasteners, after Ukrainian-American inventor William Dzus back in the 1930s.
Happy 40th 1st Date Anniversary!
Little did you know then you would have an aircraft building in the family. Not everyone has such a nice builder to work with.
You really need a screwdriver to open the oil door? That’s nuts.
Matter of opinion, a winged stud could be used there but you lose the clean look. Put a latch in, but lose the simplicity.
👋 Just caught that 😂
❤️ when you did that on your video I seriously LOL’d!!
I was surprised to see you drilling from the firewall to the nose. I would have started at the front so that any slack was driven to the firewall where it is easier to sand off a little excess. I still think you can fix that easily with just a little lightweight body filler.
Yeah that occurred to me after we started drilling. When we sized up, I pulled the clecos, adjusted, and and went front to back. It helped but not completely. That corner never fit right from day one.
@ Order of drilling definitely wouldn’t fix the problem, but it might not make it worse. I am confident you can fix it with a few hours of body fill sanding. 😁
I should have said we repositioned when we upsized the holes, which helped. But yeah, have some future body work to do.
You can correct the fit of the upper/lower cowling by adding some fiberglass to the lower cowling and sanding it to fit before you paint the cowling. It will take quite a bit of layers but you can sand it to fit; just takes time and a little work.
I am surprised that RANS makes the cowls so oversized. There is a lot of material to trim off.
They do that in case you decide to put a PT-6 out front 😆
@ Now there’s an idea!
I haven't seen the final instrument panel until now. It's really clean. Keeping to the essentials gives it a relaxed presentation. Nice job.
Oh I’ll have to do a video of the panel one of these days! Thanks!
Build up the lower cowl to match the upper w/ thickened gelcoat
How do you do that? I’m not a composite person 🙂
I’d just use lightweight auto body filler for such a small area. Not structural and much easier to work with than gelcoat.
I started my doors today and something doesn’t seem right. My aft trim strips appear to be white as are yours, but the lower and forward pieces are clear plastic with white film on the outside with writing on it. I peeled off the film and the pieces are clear. That didn’t concern me too much as I will probably paint them anyway, but my forward trim piece isn’t even close to being the right angle for the door. I aligned the top leg and found the angle at the knee to be way off. The bottom end of the forward trim strip is more than 3/4” off of alignment. Yours appears to align fine in your video. I can force the bottom into position, but it makes the trim strip wavy and slight buckled at the knee. Did you have any such issue? It didn’t appear so from your video.
Yeah, we had the same thing. Ours looked off but it needs to be that way so that when the lexan window is in place, it matches up with the angle that it’s at due to the center bow.
@ I was guessing that and asked RANS if that was the case in my email to them. A note in the manual would have been helpful. It appears my kit was in the changeover from white to clear plastic. Your parts looked to be all white and Derek’s look to be all clear. I have a little of each with two white parts and four clear parts.
What serial no. are you? I think Derek is 100 and we’re 116.
@ 115
@LTVoyager I was wondering where our sibling airframe is! 🙂
I found when fitting my wingtips that an orbital sander worked great for the final finishing. You can use 80 grit initially and then move down as you get closer. The orbital is much less aggressive than a belt sander, but quite a bit faster than hand sanding. And as long as you keep it moving and are careful, you can sand very straight lines even though it isn’t long and flat like a belt sander or hand sanding block. And my DeWalt does a great job of sucking the dust through the holes in the pad so it makes much less dust than either a belt or hand sanding block.
I am planning to run my Rotax a few times before installing my cowl for exactly the reason you mentioned. I suspect the vibration will seat the engine mounts and likely induce some amount of sag. The Rotax vibrates less than the Titan and has different engine mounts, but I think any elastomeric mount is going to settle with vibration first and then with age.
I noticed on ours that the fwd edge of the lower aluminum boot cowl skins were not 100% straight. Keep that in mind when trying to sand (straight) the aft vertical edge of the lower cowl.
Thanks Derek!
At 2:50…I placed a fairly large dab of red RTV silicone sealant right on the corner where the hose goes around. Let it dry and it becomes a permanent cushion. Stole the idea from a brother who is AP/IA.
Ah, thanks for the tip!!
I noticed the same thing with the foam and VHB. The parts manual shows only VHB and the figures manual shows only foam tape. Well, the parts manual shows it off the side, but not in position. I suspect using both is the way to go, although, VHB alone might work. Not sure it would get pressed tightly enough against the plastic without the foam. I even checked the current manuals on the web site and they seem to still be the same as my 4 year old manual set.
Joggle juggling? I've heard of this! 400 vids? Congrats!
Wow! 400, thats a lot of data! Congrats, you are getting close to being done.
So close!
Wait till you get to the fasteners I fit everything up and let it air for a cupa weeks before the fasteners Thanks for the videos
Are the fasteners worse than the fit up?
Nothing a little bondo won’t fix at the end. 😁
Remember that the engine sags a bit, so you want the spinner higher by 1/4"-3/8" on first installation. At the open house, I saw many S-21s, mine included, with spinners lower than the top of the cowl due to this.
Our engine has been hung for about a year and a half. I know there hasn’t been any running vibration on it yet, but curious how much sag it gets just being hung on the mounts. Another builder commented to me they think there should have been a good chunk of sag done in that amount of time.
I truly enjoy your videos. Unlike most other creators you show work WITHOUT a bunch of unnecessary commentary. Your dedication to DAILY work is equally impressive.
Thank you!!
Love the build. Please consider a mask when cutting carbon. Vacuum cleaner or not....
Will do!! 😬
Yes enjoying videos. You two are awesome.
Thanks!!
Worked with a guy that came to work an hour early for years on the _Monday_ after the time change. But never mind that. the plane looks great!
Good idea not to push things too far when making critical cuts. Never hurts to sleep on it.
Almost certainly overkill on the hose clamps. In 55 years of using worm gear style hose clamps, I’ve never seen one work loose. The biggest failure mode for these style clamps is over tightening them. This distorts the screw thread slots and deforms the worm gear housing and that can lead to failure.
Now you tell me! 😆
Careful…don’t be messing with Project Manager. 😂
Just curious, why did you choose a two blade prop and not a tri blade prop?
That was the recommended combo for this engine (IO-340), so went with that.
Your videos are the bomb.
Thank you!
Did you have a way to spin the unit before final drilling to check that there wasn’t any nose wobble in the spinner?
Makes me glad my Airmaster came with a nice chrome spinner that just screwed on. 😁
Cheater. And you give me guff about getting Aerosport products! 😉
@@s-21project92 I feel the need, the need for speed …. So I wanted a constant speed prop. And with the full feathering option, I should have much better glide should things get unusually quite some flight.
@@s-21project92And the chrome spinner looks very cool.
@LTVoyager Chrome is for Harley’s 😆🤣
@@s-21project92 You better get one then as you have the Harley engine of aviation. My Rotax is much closer to a BMW engine. 😂. Though my BMW definitely has much less chrome than a Harley.
You are getting closer & closer to an engine start. Please remember to install the alternator belt before you do the final prop install. It is pain to remove the prop to replace or install the belt, been there, done that.
Yes, getting close! And, yes, will install that belt. Left sitting on top of the engine so we won’t forget 🙂
What's all the hubbub, bud? Looking good!
Thanks!
You may have posted this on another video but can’t find it. Where did you find the panel trim strip?
It came with the kit, but I’ll bet Rans sourced it from McMaster-Carr. www.mcmaster.com/product/1120A341
I would bet that Clint at Vetterman would move the fitting on the heat muffler for you at some saving$.
I thought about contacting Clint, but decided to just go with what we have. It’ll work, already have a game plan 🙂
@@s-21project92yeah, mine is looking like it will be fine. Finally got a couple hours in on my project tonight.
I had fun running the heater hoses for my Rotax heater and they are just 3/4” heater hoses for water. Looks like you are having even more fun running your SCAT tubing than I had with my heater hoses. The water hoses are much smaller, but they are also much stiffer and getting the spring clamps on them was fun to say the least.
You bought all of those Aerosport parts and you are worried about $400 for a heater muffler? 😁
Had to draw the line somewhere! 🙂
That is beautiful! You two are doing really nice work. You will be able to fly it with lots of confidence.
Thanks!
You’ll never use that handheld radio. I wouldn’t have the extra equipment flopping around.
We’re single com, so I’d rather have it and not need it instead of not have it and need it 🙂 Plus I’ll have the antenna ready for if we add another com.
@@s-21project92 talking on the radio is overrated 😎😉 NORDO rocks!
There are some (maybe earlier) heater boxes, that have offset inlet/ outlets. I felt that might make running the hose easier. Ours is like yours and I ended up trimming the inner corner of the oil cooler bracket to keep it from rubbing. I also used two sets of clamps on the intakes.
Shelly is checking to see if they can get me that offset shroud.
