RE: Redwing 30cc Sbach Build
Hey guys - I'm unloading the last few 50cc sbachs I have for the year at stupid cheap prices, to assist me in getting in my next container load of planes. If you have friends let um know. If you have enemies you want to make amends with, let them know too :)

RE: Redwing 30cc Sbach Build
Got two new Sboch pilots today. My friends Mike and Bob know how to hook up Mode one and Mode two on the Buddy cord and that allowed my friend Bill to fly the Sboch. Rafael got his hand to stop shaking long enough to take a turn on it also. To keep from repeating myself to much They Both liked it.
My problem seams to be solved. The plane had no trim problems with the new radio on (4) 12min. Flights. The other radio is getting sent in for a check up. The problem wasn't with the servos. BTW I'm getting better at hovering. Still not good just better. |

RE: Redwing 30cc Sbach Build
ORIGINAL: Tseres I have a couple of helis that hover well. No thill there. I find it quite a thrill when my heli hovers!! It means nothing is broken for once, or that I havent noticed what is broken.... yet.. |
RE: Redwing 30cc Sbach Build
I took half a day off on Monday to fly my 160 Reactor and Redwing 30cc Sbach. I had flights 3 thru 7 on the Sbach and loved it more and more. This thing can snap inside and outside so cleanly and stop as soon as I release the sticks. I mean if it was in knife edge attitude when I release the sticks it would stop in knife edge. I literally hear the airframe reverberate for stopping so abruptly. Most if all the planes I have ever owned over rotate. That includes the Extra's and Yak's. My Extra's over rotate the least but still.

Four more flights under my belt on this bird. My DLE 30 is breaking in and idling lower. I have found that with 60% elevator throw I can jockey the throttle to harrier around the sky, steering with rudder and ailerons. Practice will get me there much faster with this Sbach than any other planes I have owned.
I discovered that to enter the harrier I must get the wings to stall first. After that it isn't very difficult as long as the engine speed can be varied in fine increments of a few 100rpm's (guessing) or so above 1800 (again guessing). The DLE 30 is very reliable and has a fine throttle response. This combined with the awesome flying qualities of the Sbach, I am looking pretty good in harrier. The wing rock is very easy to stay ahead of with this bird. |

RE: Redwing 30cc Sbach Build
Yes, the Sbach harriers VERY well. All my theories on what makes a plane harrier well have seemed to be disproven by antoher. but it's a good plane to try them on if you are not very good. I'm not very good with harriers, and I can do it easily with the 50cc sbach (which is what I'm flying currently). TJ (T3Beatz) gave me some good advice on them. He told me not to overwork the ailerons, and that solved 50% of my problems. I was trying to control the wing rock with the ailerons, when just a movement of the rudder seems to help level it out, without the OVERthrow that aileron control creates.

RE: Redwing 30cc Sbach Build
I try to move the rudder with the ailerons. A little bit with each one in the same direction. That seams to work I just need practice.

RE: Redwing 30cc Sbach Build
I think I lost the Sboch to my son today. He said that he is selling all his glow stuff since he isn't going to fly them anymore. I let him have it since I crashed his gasser I gave him last fall. I still have to take care of it for him, since I'm his favorite mechanic.
I look at it like this. He likes to go flying with me and that gives me more time with him. Pus it gives me a reason to get another plane. I hope you have some left Tim. Maybe a 50cc Python. Has anyone done a thread on a Redwing Python Yet? |
RE: Redwing 30cc Sbach Build
Hi Tom
I do have 2 of the Pythons left right now. I'll be happy to get you one. Well, at least if your son has it, you can still fly it from time to time! :) |
RE: Redwing 30cc Sbach Build
My Sbach is all but ready except for the fact that I need to customize the JTEC muffler. It's a DLE30 muffler and the hole spacing is around 2mm off. Also - the cooling fins on the MVVS are too close to the exhaust port for the JTEC to fit so we are making up a flange to raise it a bit off the exhaust port.
This is my first JTEC and I was disappointed to see there is nothing in them that stops them from crushing when you tighten down the mounting bolts. We will make sure to pit some 4mm pipes through where the bolts go through. Otherwise, the vibration is bound to knock them loose. This surprised me greatly because I had only heard good things about JTEC mufflers I stumbled across another ting and this is something I will take up with the factort. The manual has a cross section of the wing with a CG symbol but no dimansions. There is no way I can market that to my customer unless I have an addendum with the manual (which is pretty ordinary as it is anyway) I take it the CG should sit on the wing tube? Maybe the rear edge of the tube? |
RE: Redwing 30cc Sbach Build
The Back of the Tube seems a really good place to start. That is where I put mine.

RE: Redwing 30cc Sbach Build
Got my first Harriers in Yesterday with the Sboch. Did Good for my first tries. One real good one into the wind. Got the wings to stop rocking with the throttle but that part still needs a lot of practice.

I'll also do a build thread. We can Share it if you like. It would be interesting to see the different approaches to the same plane. |

RE: Redwing 30cc Sbach Build
Tseres,
Yes, I found out the same thing that by running the engine at a slightly fast idle wing rocking in harriers will go away. This was becoming my favorite plane to fly until the other day. I tweaked the hs on my DLE 30 a bit too rich. Took off and went into a hover too close to the ground. Engine loaded up and died. I flopped it almost straight down from about 20 feet with a bit of forward motion. The gear bent back 90 degrees but stayed on the plane. Nothing came loose including the engine. At home, I disassembled to inspect the damage. Firewall popped out on one side. Gear plate got crushed on one side. I am really pleased that the damage was minimal. Some elbow grease and it'll be back in the air. Learned my lesson about how sensitive the needle valves are on the DLE30, i.e. leave a good thing alone. |
RE: Redwing 30cc Sbach Build
Sorry to hear about the mishap. A little bit goes a long way on the needle valves. That is the same with all engines.
It sounds like you can fix it. I'd like to see what you due to fix it. Sometime you can learn more by fixing then building. Can you post some pictures of the fix here on the thread? |

Someone asked what I did to access the bottom cowl mounting screws. I should have shared that in the original build so here it is. The engine needs 2 to 3 times the exit opening that the size of the intake opening is. This rule is wise to follow with gassers. I made a huge opening for the size of the plane and that allowed me to fit my fingers in to start the bottom screws. Then I opened up a small hole inline with the screws and opened them up as needed so I can get a ball driver on the screws. I had to use a lock washer between the flat washer and the head of the screw to keep it from coming loose. I don't like to use locktite here. Don't be afraid to make the big opening.You can't see it on the ground or even on a set up table. I haven't even been able to notice it in the air at 100mph:). |
RE: Redwing 30cc Sbach Build
The big opening helps, it keeps it cooler in the cowling.[8D]
