Anyone running FM have issues with glitching due to the LONG servo leads on the rudder and elevator?? I have tried running the antenna several different routes, and finally got the best range check with the antenna routed outside the fuselage and forward instead of towards the tail... but I am still getting interference when the airplane is pointed away from the radio.

Any suggestions other than switch to 2.4G?

Yes I have had the same issue with my FM radio. I have been messing with it for awhile now and most of the time I have no problems with it. I almost destroyed my Reactor twice last weekend because of glitching. It is very irratating considering every piece of electronics in the plane is brand new. My next big investment is a 2.4G radio. I bought a bunch of tickets for a raffle of a brand new Spektrum last weekend but I guess my luck wasn't there. [8|]

On another note has anyone had problems with there Graphtech gear?? I bought a set back in February and they craked the first time out but had held together since then. I fly off grass and they flex ALOT during landing. Now they are so flimsy they cannot even hold the plane up. I had to go back to the stock gear.

Interesting about the carbon gear... I was considering purchasing a set...

As for the interference, well I added a ferrite ring to the three long leads running to the tail... will range test it again this evening and post my findings.. If it does a normal range check, I will post pictures of my antenna routing and how to install the ferrite ring... I am also going to repeat the range test with the wings installed, but I doubt they will cause any interference since the servo leads are not near as long as the ones to the tail.

TruBlu02,

I have the Graphtech gear and it's pretty nice. It gives just a little to absorb the shock of the initial touch down. Never heard of anyone having a problem with the gear.



GarySS -> RE: Great Planes Reactor GP/EP 3D ARF .46-.70 (10/1/2008 5:19:02 PM)

Finally got my Reactor up with 5 flights using a Saito.82. I got a little twitching on my rudder servo, but eliminated that by making sure my antenna was completely away from all other wires before being threaded into the stock fuselage tube. Running Hitec HS 5625 digitals and a HS945 on the rudder. Radio is FM Futaba 9C with the 8 channel RX. Adding 3-4 twists in the long servo leads might also help more.

I am running stock gear with wheel pants and taking off and landing on a grass field without a problem. I just use my tripple rate switch on 3D setting for take-off to hold the elevator in full up until the speed is built up. Then I hit the switch to a mild setting which allows the tail to rise and off I go. Landing is OK by just keeping the elevator up after slowing down once down. Taxi-ing back to the pitts is again using the 3D elevator up setting.

Full Disclosure: The grass field is smooth and cut to about 1/2 inch so that helps, I'm sure. [:)]

My Reactor is about ready to go. Saito 82 with a Keleo Pitts muffler. All of this talk about glitching made me take a long look since I haven't finished putting all of the Radio gear in. The tube for the antenna is pretty close to those long wires. I was on the fence on whether use a 72Mhz rx or a 2.4 FAST receiver. I think I'll save the 72Mhz for something else!

Well I spoke with the guys at graphtech yesterday about it. I have had the gear since Feb and they have held up well till now. I described the problem and they are going to lay up a new set of gear for me and try to beef up the heavy stress area. They are selling me this set at a 30% discount so hopefully this new set will be better. I absolutely hate the stock gear. My field is a little too rough to run them in the stock position but having them turned around moves my CG forward. It is a lose-lose situation.

sseward,

How is that Keleo Pitts muffler working out on your Saito .82? How is the sound. Have any pics?

Zippi,
I just got it Monday and just got the cowl fitted last night. I had to cut just a small opening at the front of the cowl to accomodate the corner of the muffler, even after I ground the corner down a bit, but it still comes out of the cowl nicely. I may also trim a bit of the down pipes as they are quite long. I ran down to the shop and snapped a couple of quick pictures so you could see how it fits. I'm going to repaint it with high temp engine paint, then it will be ready to run! Since this does'nt go back into the tunnel, i'm going to mount my fueling port and remote glow adapter back there.

As for the sound, obviously i haven't had it fired up with the muffler on it yet. I will say that it fits great and is beautifuly designed.

If I don't get it maidened this weekend then I at least hope to fire it up to set the idle and engine cut-off. I'll let you know how it sounds!

The Keleo muffler looks really cool. This is definately something I am interested in. I went to Keleo's website and they don't have the .82 listed. Is this the muffler for the .91?

I bought the one for the 100, which has the same threads as the 82. I noticed however that he doens't list that on his website. Maybe it's the one for the 125....should be the same also. Just e-mail Kelvin and ask.

ceriverob -> RE: Great Planes Reactor GP/EP 3D ARF .46-.70 (10/12/2008 12:42:45 AM)

Hello,

I just bought this airplane and I'm very excited after reading many of the post here, and I've to say that I bought this airplane because I have one Saito 82 available in my hands after crashing my Aresti :-(
I'm very happy to know that this combination has already been tested and found to be a winner, I'll certaintly pay much atention to all tips & tricks published, and would like to take this opportunity to thank everyone who has uploaded pictures of their airplanes and take the time to explain in details their setups and flight experience, this really HELP THANKS !!!!!!

One question I still have regarding the Saito muffler is why anyone didn't try to use the Saito Flexible muffler listed on Wholesaleplanes.com?

Isn't better to use the flexible muffler in regards to avoid cutting the cowl to?
Can this muffler be use with the 90 degree adaptor?
What about the Turboheader muffler and the cowl cutting? -I believe I didn't see any pictures of this setup.

Well, I believe it will take me some time to even start the building because I'll be traveling for work for the next three or four weeks, but in the meantime I'll see if I can start buying everything I need to expedite the process and of course......will be reading this thread very often !

Hey hipsters

after getting some other projects taken care I placed my order today for my reactor.

Question:
anyone flown one yet using a os 61 fx? I have one of these that could use a new home. I will continue to read through this topic, but I have not noticed it mentioned yet. I would like a 3d machine, and I know that 4 stroke is better, but if I can save the cost of an engine, than its gravy (and also a happier spouse).

As always thanks for the replies..



MaxThrottle -> RE: Great Planes Reactor GP/EP 3D ARF .46-.70 (10/14/2008 10:36:25 PM)

haven't been to the post for a while. Trublu02 ... yah I did have a problem with mine actually the first time out. Was a normal landing but it cracked on touch down.

I mentioned the whole thing to Graphtech and they quickly replaced it. Placing another order for other stuff probably helped but I mentioned it should be a little thicker even if it meant making the whole in the fuse a little wider.

The second one I got wasn't any different in specs but I was in a low level flat spin in crossing winds and dead sticked. Yah one of those perfect storms. It came straight down on the gear. Surprising.... no issues. Cracked the inside fuse frame but little else.

tough bird to break.



Sergius -> RE: Great Planes Reactor GP/EP 3D ARF .46-.70 (10/16/2008 12:50:15 PM)

I'm new to carbon landing gears and my question is:
Is something wrong with these Graptech gears?



TruBlu02 -> RE: Great Planes Reactor GP/EP 3D ARF .46-.70 (10/18/2008 1:32:57 AM)

It's hard to tell from the pics of the gear that you posted but it looks like the ends of the gear are not square. That shouldn't be a problem since they do not touch once they are installed in the fuse.

On another note I got my second set of gear from Graphtech and they are thicker at the base and slightly shorter in length. I did notice that they are slightly more narrow though so they are still the same height as the old set. It was a REALLY tight fit sliding them into the fuse but they appear to be substantially stronger than the last set. I spoke with Graphtech about breaking the last set and they said they would look into making them stronger. Looks like they followed through!



2daysoff -> RE: Great Planes Reactor GP/EP 3D ARF .46-.70 (10/22/2008 8:36:16 PM)

Ok gang got a question


I have my reactor and have been working on it.. I have carbon tube and gear on the way. I am trying to figure out the best engine. I am either going to put a saito 82 or the saito 91. Is the 91 an over kill?? I can get it for 10 dollars more, but is it that much of a difference?

I am using standard size digital servos all the way around with the exception of the throttle.

1) nope.

2) yup.

If you were going to own this plane forever, I'd say to buy the .91.

However, the .82 has lots more applications (in the 48" wingspan class of planes) where the airframes for the .91 are quite limited after you stuff (or get bored with) the Reactor. Where will its components end up next?

A 4 stroke engine for a .60 size airframe...I'd go with the Saito 100 since it's almost the same size as the .91 (I'm going on memory here) but is significantly more gutsy. I don't think it will fit in the Reactor but I may be wrong.

Fun plane...you'll have fun with it!!!



TruBlu02 -> RE: Great Planes Reactor GP/EP 3D ARF .46-.70 (10/22/2008 9:24:10 PM)

The Saito .82 is great match for this plane. I love the balnce of power to weight of the plane. But to be honest I really don't think it would be overkill at all to use the .91. If you search through this thread you will see that there are a few guys who use the Saito .91 and love it. Just remember though that this plane has a tendency to be nose heavy so take that into consideration when using a larger engine. I had to cut the covering back to put the battery in the tail. If it was me and I had the oporrtunity to get the .91 for that cheap I would do it in a heartbeat. Remeber you can always pull the power back. Good luck!



2daysoff -> RE: Great Planes Reactor GP/EP 3D ARF .46-.70 (10/22/2008 10:02:06 PM)

Kolar, great point on the ability to use the engine in other applications, never thought of it that way...


I have been reading back through the posts here, tons of information. I might stick with the 82, seems a win win deal either way and like you said it is a great engine for other airframes. Like I said it was a question I had since I could get the 91 for a few dollars more.... Thanks again.



zxxflyer -> RE: Great Planes Reactor GP/EP 3D ARF .46-.70 (10/31/2008 2:18:35 AM)

Anybody seen the new giant scale Reactor ARF from Great Planes??!!! Tower Hobbies has it for $430 I think I will start saving up for it now..... [:D]

Stock #TL2052



stealdesk -> RE: Great Planes Reactor GP/EP 3D ARF .46-.70 (10/31/2008 4:57:59 AM)

There is already a thead going for that.



zxxflyer -> RE: Great Planes Reactor GP/EP 3D ARF .46-.70 (11/1/2008 12:31:17 AM)

well thanks for the cheery info and the link! [X(]



McChiken -> RE: Great Planes Reactor GP/EP 3D ARF .46-.70 (11/1/2008 12:44:11 AM)

Hey Zxx , Was readin through this thread and saw your issue with servo glitches . I recently put an aeroworks .40-60 edge540 together and had the same problem . But I was getting the glitch on the pull-pull
rudder setup . Also got glitches on the throttle servo . I finally realized it was mixing futaba 9252 digital servos with analogs . I had 9252's on ailerons and rear mount elevator . A 965mg hitech on rudder and
a hs-225 on throttle . The reciever I was using was a 168 futaba . I found the solution to be removing the 168rx and putting in one of my 139 PCM Rx's in instead . No more glitch . The glitches were big , full 3d throw glitch and would have caused a crash . So mixing analog and digitals myth holds true to my experience . Something in the PCM Rx shields the servos from interfereing with one another I guess .

Anyone know how well this plane does rolling harriers? I have a Saito82 sitting around from a Ultra Stick I tought how to do cartwheels . It sounds like it does other 3d pretty well .



jkovar -> RE: Great Planes Reactor GP/EP 3D ARF .46-.70 (11/1/2008 4:12:51 PM)

Well mine is in the build phase....

so far every thing is lining up nice. slight warp in one of the elevators but taken care of. I got a sweet deal on a Saito 82 on Ebay 235.00 total WITH ups shipping. I have a carbon tube and gear on order as well.


My Canopy is taking a navy blue rit bath as we speak. 20 minutes into it and it is actually taking the dye. I will post some pictures when its done.


The cover job was crap with a ton of wrinkles. So far I have not had a single issue with the trim coming up...
