JR Heli Vibe - Airskipper - Sylphide - Venture > Voyager 50 Rocket Ship!

Today saw the first test 'hovers' of my new JR Voyager 50. This isn't a standard Voyager, it has the 10 tooth pinion making for an 8.8:1 ratio which results in ~1900 RPM at the head at the OS 50's optimum operating speed as opposed to ~1740 for the standard Voyager.

My Voyager also has the Curtis 60 size muscle pipe which proved to be a bit of a pain in the ass to get going. The heli wouldn't start, it wouldn't idle and was all in all, a royal pain in the ass. Then we adjusted the gap between the header and the pipe to about 3-4 mm (thanks Wayne) from about 10mm and all of a sudden the heli started first pop, idled great and once we leaned it out quite a bit, the heli started howling like it should.

The heli required no tracking and as yet, no trim adjustments and hovered about 4 - 5 tanks on Darryll's back yard.
We didn't get a chance to get to the field (is pretty much dark by 6pm now...) so I'll have to leave the full on opinion until I've had a chance to thrash it around a bit.

With the bigger pinion and the Muscle pipe, I wouldn't be surprised if the Voyager beat my 91 powered Vigor off the mark. It certainly seemed to jump when asked!

Can't wait to get to the field and rark it up a bit!

Congrats on the V50, you'll like it, it's a very spritely little thing.

Later on, you might want to spring for the upgraded 3D centerhub when you wear out the stock unit. Also, we've been flying these for around 8 months now and our only long term performance issue is the weak side frames which tend to break near the engine mount.

The CF frames are ridiculously priced. I'll wait for an aftermarket one or you might want to try the upgraded JR engine mount with rubber damper like the one posted on cyberheli to avoid this problem.

Also, make sure you secure the charging jack so that it doesn't hit the main gear in any orientation, we had a weird freak of nature accident when the charging jack got caught between the main gear and the pinion and caused a new V50 to go in from 80 feet straight down.

P.S. The one piece plastic skids from K&S (for the Shuttle or Ergo)looks fantastic on the V50, lower profile and alot stronger than the stock unit.

Looks great Si, My IMZ 50 came Thursday. I had neck surgery the same day so I can't work on it right now. It will be a week or two. I'm also going with a 8.8 ratio. Stephen sent me a 10 pinion and I obtained a 88 tooth main gear locally. I chose 600mm-W V-Blade with a 60mm cord. The IMZ RV50 should pull them with athority. I only have one question so far. Looking at the Japanese instructions, I'm not sure if I need to use the washer between the fan hub and the engine. It shows the washer with writing explaining it but it's a toss up what it means. Maybe when I get closer to that stage it will become clearer. I may write Florian he used an OS.50 also. Did you use the washer with your OS?

Rick,
I have to be honest and say I can't remember! I do recall a washer with the engine and I'm PRETTY sure that I used it (if the instructions said so, then yes I did).

I'm REAL excited about this bad boy eh. Maybe even more so than my 91 CS! I cannot wait until the weekend to give this sucker a good rarking!

That muscle pipe just sounds sooo sweet...

I'm REALLY glad I got the 10 tooth pinion for it eh. IN comparison to my mates one which has the stock ratio, mine just hums!

Hehe that's my proplem, the instructions are in Japanese. I will have to strictly go by pictures. And the picture is not clear for the washer and for what engine both or neither to use it with. I'm sure I'll get it figured out once I get to that stage.

Rick,

The IMZ main gear is 84 teeth and once you see the pinion it comes with you'll see that you can't use the 10-tooth upgrade! The teeth are machined off to provide clearance for the tail part of the split gear! Also, the regular Voyager main gear won't work on the split gear set-up! The gear ratio is 9.33, which is fine for either the IMZ or the OS.....no need to get the 10 tooth for it!

Si,

One thing to be careful about with the 10-tooth pinion is your tail speed.....With the stock 17 tooth tail gear you'll get close to 10000 rpm at a head speed of 1900!!(1900 *88/17 = 9835 vs 1900*88/20 = 8360) That's really fast! KSJ makes a nice light aluminum gear with 20 teeth part number 557 or a nylon version part number 598. The stock version has 17 teeth. I have the nylon version and it's great. Horizon has them.

I have also had problems with the thin frames on my Ergo. I have the CCPM carbon frames coming from Japan. I would have thought that they would fix that in the Voyager!!! How thick are the frames?

Thanks Florian, I wish I would of read it about 45 minutes earlier. I tried to get it apart but a no go. I place a order to Stephen. I'm building the rest of the heli stock. So much for my first nights attempt. :-( I'll have it back to normal next week.

Thanks for the tip any way.
