Cool model for sure. I built it straight, added some right rudder by cutting just the top line and bending it along the hinge line. Loaded up the motor tube with 4.5g of 1/8 FAI rubber(two loops) and a rubber hook to keep the rubber from climbing the hook on the prop shaft. After trimming the pitch axis by moving the wing aft a few mm from my first guess, it was ready for first powered flights. 100 turns to start out - perfect right/right flight that could have been done in a 40x40 room with a 15 ft ceiling. 200 turns for the second flight - the climb opened up a little but was still to the right with a perfect right glide and about 40 seconds of flight time in completely dead air. 300 turns for the third - initial burst almost stalled the plane but it pulled itself out and climbed to the left of launch heading by about 45 degrees before turning back to the right. Glide was great again and total flight time for the last flight was right at a minute, but I landed about 10 ft up in a tree. You couldn't ask for more fun from something that is so easy to fly and wind. :)
Great video! Hard to believe that something so capable is available as a mass produced model! Can't wait to try one out. Also, thanks for being in the forefront for model aviation, I especially liked your Jet-x video and am hoping all goes well and we can again enjoy jet powered models. (I still have one from many years ago)
After receiving the missing nose-ring, I test flew mine with the lubed stock rubber @ 6 strands and about 300 hand turns. Based on your other videos, I had a 4-strand 1/8 SS motor in my field box - just in case. The stock rubber was not very satisfying and broke after three attempts (stretch wound for the second and third attempts), the third with about 700 turns. switched to the Tan SS motor, and with 500 turns got a flight of over 4 minutes (11 AM, temp over 80°, light and variable wind) landing about 300 meters from the launch point in the next field. I was completely soaked, and due to the increasing temp and breeze, called it quits for the day. Dethermalizer definitely recommended!
I just finished a conversion of one last night. I'll get some video, its a hoot to fly! The full conversion (rudder and elevator, no motor) only added 4.11 grams.
Check out the youtube channel 'domoremath'. He flies this plus various other rubber powered models in a small park in the middle of New York using micro gear on the rudder to keep it within the boundaries of the field.
@@rossclements8874 nice to find you in the comments, instant sub! I‘m planning a similar build as yours using the hardware of an old broken mini vapor of a friend, really looking forward to it 🤩
"Don't land it on the shed please..." How many other modelers have said similar words? Good stuff! You do know that there is a small critter behind you.
That’s a wonderful little flier! What class of aircraft is this? It certainly has an unusual appearance for a rubber powered free flight aircraft of its size.
The English Language instructions say, "Sky Voyager Model B accords with the Chinese Competition regulation of P1B-1 Class rubber power model plane: 1. Weight while taking off: no less than 40 grams; 2. Wingspan 648mm; 3. Power rubber: no more than 4 grams."
It is a great model, maybe nearly as good as the AMA BETA, does this come with a winder? Just busting chops! Seriously does it come with FAI rubber? if not lets arrange it.
joshuawfinn - Glad to hear everyone’s doing great. Yeah it’s really tough around here without him. 😔 Especially when I’m out in the shop. I appreciate you following alone. I should have a video up in a few days. 👍🏼
Now that looks great! Can I purchase 2 of these in the near future? 1 for me, and 1 for my grandson. It does look like it could use a little trim work though. Sincerely, Jon B. Shereshaw
I bought this thing on the basis of this review. I found the instructions (written in Chinglish) pathetic and severely lacking in detail. Despite this, I got it together and trimmed through the gliding stages. There is ZERO info on how that prop system works, and I had to remove one blade and massage the hole before it would fold (the other was properly loose). When powered flight was readied, the prop will turn less than a revolution before the little tab lands in the little slot and stops everything. You sort of, kind of mentioned a little about it, but the camera was so busy waving off a Hellcat from the fantail of the USS Enterprise that no detailed imagery was provided. I finally figured out that the piece with the little tab was also nearly seized to the prop shaft. A pile of work later and it was finally free. I got in a 50 wind flight, a 100 wind flight, and then a 125 wind flight before I ran out of rubber bands (there are only two spares with the kit). The plane would land, the wing flex, and ZING would go a rubber band into the grass. I now await a bag of #12 bands to continue the testing.....
Too band the designer didn't do what he did for the horizontal stabilizer. The two slots there will capture the rubber band and not throw it 10-15 feet away into the grass. I, too, bought a bag of rubber bands to use with this plane.
I've been test flying my P1B-1 and suddenly the rubber power band broke at the prop end (all strands). What is the maximum number of turns that should be used with this model? There is a spare rubber band but before I try again with the backup band I thought I should ask the question. Also, the instruction sheet says "The spiraling radius (rudder to right 1-2mm) is suggested..." which will make the model turn to the right. This seems to be my model's natural tendency when under power and gliding and matches the Test Flight statement in the instructions that says "The model is adjusted as right spiral climb and glide in general". I don't think this matters much (aside from the prop torque under power, perhaps), but I thought I would ask. I ask this because you set yours for a left turn.
Upon inspecting the rubber motor that broke I found that I have 7 strands, not 6. This may have had influence on the rubber band breaking. I also note that Joshua's video on braiding rubber band motors includes lubricating the rubber. I have obtained some Dow 33 and will try Joshua's braiding and lubrication method with my remaining motor rubber.
Is that the same style propeller you use on your rocket gliders? Man, I still go back and watch those videos occasionally. Just one of the coolest ideas.
Hello I hope am not to late I love your videos, keep it up 👍 , I need help finding this beginners plane when I hit the link it’s not there ? Where can I get one? Thanks for the help!!!!
Just got mine the other day and have it assembled. I have no experience flying these types of planes and at a lost when it comes to trimming. I am an actual glider pilot though. LOL. I see trim tabs embossed. Are they to be cut and adjusted?
Craig Miller you can definitely use the tabs to help with trimming it. If you go to the Technical Library at freeflight.org and look up the 10 Step Trimming Guide, you'll find some very useful information on trimming free flight models.
joshuawfinn thank you. I came up with a few different solutions for trimming on my own but have not implemented them yet. It will be interesting to see how more experience pilot do this. Once again thank you. C
Dear, Sir Hello from Thailand. Could I have all the details to make it, please? I'd like to learn how to make it and teach my students after then. Thank you so much.
This isn't one that you can build from scratch. It's molded plastic and heat formed foam. There are a lot of balsa designs out there that are suitable for scratch building; I would recommend looking at P-30 class models for that option.
Larry Jessup here's the link: jhaerospace.com/product/p1b-1-sky-voyager-model-b/ Bear in mind we're sold out right now. These have proven to be far more popular than we expected.
@@joshuawfinn I was looking for it and found a website the language looked like Seminole Indian mixed with Japanese. I was able to successfully order it from your website. Going up north to Ocala Florida to build Sig Cub with my grandson July 15th this would be icing on the cake. A lot of big fields up there.
