P Gasser

[Rodney]

Well I got to try one out after teaching some setup for 3D flight.
That machine flew better than I thought it would in stock form.
Thanks Darrel for letting me test it out. Would have liked to see Dan's Condor go but it didnt happen.

[DebianDog]

Yeah tell the Century Rep to bring gears, next time, in case some stupid ass melts them on a hot start :oops:

Damn good wings though Rodney ;)

[Adam Turner]

All Preds fly well stock!!!!!!!!!! :D :D :D
Didnt you already know that.

The Pred Gasser benifits from a gear change if you really want to see i t go. I think I'm running 6.92 right now and with the speedups in the tail she awesome. I'm sure stock would be fine, but you gotta upgrade something :D

[Rodney]

To be honest Dan I learned that if you go to events and you fly Century, You must bring spare parts for yourself as none of my Helifreak friends fly Century.
But the P Gasser didnt have the metal A arm. That is all that is required in my book.

[Rodney]

Well I decided to go Gasser power. I am going to convert my pmax to a 26 hanson powered gasser. Anyone got any info on this motor versus the Z231.

[DebianDog]

You know I have always "heard" the Hanson G26 SUCKS and the G23 ROCKS but have yet to see it. In all the gassers I have seen fly mine flies as good or better. I will show you how nice and smooth the old girl flies next time I see ya. :smokin:

[Rodney]

What motor so you have in yours Dan. I heard the same thing in the past. The 26 wasnt worth the extra cost. If any one has owned or flown any 26's please feel free to give your input. I dont think anybody thoughts are bad thoughts just want o get a few oppions on this matter before I buy.

Helifreak friends fly Century


We do when we fly yours Rodney!! Damn nice flying machine and seems to hold up well now that you have learned and taught a lot pf poeple how to properly build and maintain a Predator. I was impressed with how your flew for sure. Nice flying machine.

[lakespinner2]

I can't help very much at all because I've never flown a gasser with a 23. I do have a predator with a G26 (hanson) and it seems to be ok. I've only got around 4 or 5 gallons through it but it seems to haul around a camera mount and camera pretty well.

I've heard the 26 is not as smooth; I'd like to see and compare the two side by side. Well, maybe on second thought I'm better off not knowing. :wink: In fact, I'm very slowly building up a second predator with a hanson G26. I'm inspired by DD's condor so this one will be a 'stretched' version. :noteworthy

[Rodney]

Cool send pics when it is complete.

Rodney,
If you want to go with the 26. Then talk to Chris Bergen. His gasser is smooth running and it has a 26 in it. But I believe Larry and Chris blueprint the motor before they install it to get to run that smooth. Doing that has a lot to do with how smooth the Zenoahs run. They have a two piece crank shaft and they need to be trued back to 0 if I am not mistaken. Chris can probably provide more info than me.

Resist the temptation and just put a G231 in. You'll save yourself a lot of time and frustration.

If you keep the G26 under 10K RPMs, it behaves pretty well but just doesn't make enough power. If you run it 11K and more, my experience has been that bad things happen to your helicopter over time

your mileage may of course vary.

Chris has been running the very first prototype TRM G260PUH he got from me since before B-Ham last year. It is a ringer of a motor. More often than not, from what I see and hear, the 26 is not a great choice in a heli, no matter who builds it. One will run great, and one vibrates to the point of fracturing tail booms and stuff like that.

The 231 avoids almost 100% of the bad vibs, and I would ahve to say...go with a 231.

[Rodney]

Thanks for the info folks. I think I will stay with the 231 as I was told to before when I wanted to try this out.

[Tom Fiddler]

The 231 is a great engine. Rodney,
You won't be sorry.
If you need more power run it on alky (Just a carb change) for 15 minutes.
Bergen is the only Heli I know of, that does not have "some" problems with the 26.

[cbergen]

Sounds like Wayne Mann's Caliber runs the stock G26 w/ no problems either.

And no, we don't do a thing to the motors before running them. I do have the TRM 260 in my gasser, but only for power comparisons. And cause it's cool to run!!

Stick with the G231 in the predator. If you gotta have more power, get the TRM or hanson modded.

[Billme]

Whats wrong with you folks? I like my 26:) The long wait for the new clutches is over btw..Got mine Friday, flew it today..I do believe it was worth the wait:)

Bill.

[Tom Fiddler]

I knew I would draw you out of the wood works with that G26 statement Bill!!!
Does everyone get a new clutch or just you?? :D
Tell us more.
Chris don't tell me Waynes got a "Belt Drive" Caliber ZG.
Send me a link :D
If I could shave "mear" 2 POUNDS of this Vario you guy's would be in trouble :D :D :D

[cbergen]

Here's one of the posts where he tells about it.

http://runryder.com/helicopter/t232836p1/

Hopefully they had China make A LOT of those clutches!! :twisted: :twisted: All the reps are gonna need 'em. :D

[Billme]

First off, the the reason the ZG does good is because of SIZE of the clutch. the reason the GSR does good (ecept for the auto clutch), is because the size of the clutch....Do we see a pattern here? Not to mention the Vario:)
Just proves my point....Did you hear that Chris bergen?") After what I witness today, it proves my point to the letter.. I can't wait to get my 3D machine going. Dang, I'm going to have to redo my Ratio, hehe..
The liner is new automotive type that has metal in it...Don't know a thing about it, but I hope it last as they claim. I'll know more as I get more time on it. Pretty neat stuff..
Everyone gets to buy the clutch, they are in stock now, while they last:).. The whole system is 100 bucks retail... YOu get a new hub, clutch and bearing block, and new clutch bell... Not bad huh?.. The tolerences are close, so make sure you have everything dailed in real good....

Bill I am glad your working hard on all things Gasser.
I just heard of the ZG last week and I must say I like some things about it.

[DebianDog]

From the thread:
"Before I started building the kit I was a little nervous about putting the G-26 in because of the horror stories that I have read about this engine regarding vibration, mainly from Miniature people with their new gas machine. I stuck it in anyway and it runs as smooth as glass. The fuel tank sits perfectly still and there isn't any visible vibration in the machine anywhere."

I have found the same to be true. Sorry. Also Century is not the only manufacturer with clutch problems ESPECIALLY with low head speeds. ;) I am running Condor at 1250 with no current issues (other than an idiot on the sticks) :roll:

[cbergen]

The head speeds aren't the problem. Try flying your bird with the ENGINE speed at 8000.....

AS I have pointed out to those with problems, if you want a 1200 headspeed, then GEAR it for 1200 headpeed. Put the 6.4 gear ratio in your condor and run it at 1200 headpseed. I doubt even the new clutch would hold.

[Billme]

Who would want to do that chris? Yes, always gear for the rotor speed you need, but you must account for back pressue on the engine too and you must have a clutch to handle it:) .. BTW, I tested the clutch at 1200 with the 8.1, and the clutch done fantastic..
;)
