Hey Night Scream I sent you a PM.

RE: Redwing 30cc Sbach Build
 

The IMAA Fly In is history. The Sboch made a great showing. There is two things that I know I cant do. One is 3D and the other is fly and take pictures. Sorry I don't have any pictures to up load of the Sboch. Altho the flat spins were impressive and since my engine is broke in I did a vertical climb until someone said where did it go. That is a testament to the JCs power. I can tell you that it takes a long time to flat spin down from that altitude. One thing for sure was that the plane impressed the crowd.
Road Trip again tomorrow. See you guys when I get back.

RE: Redwing 30cc Sbach Build
 

I did find one where the Sboch was in the background. Someone will have some photos that they'll send me and I'll upload them when I get them.

RE: Redwing 30cc Sbach Build
 

Ted sent me a picture that he took today. I knew someone would come through.

RE: Redwing 30cc Sbach Build
 

A great looking piece of work if I do say so my self! and the plane doesn't look bad either! LOL:D

RE: Redwing 30cc Sbach Build
 

Thanks T.J.

Can I borrow your thumbs for the next meet? :D

RE: Redwing 30cc Sbach Build
 

Sure, but you will have to take the index fingers also because I'm not just a thumb flyer... I use them both http://www.rcuniverse.com/forum/js/f...eeth_smile.gif.

RE: Redwing 30cc Sbach Build
 

That sucks for me.[&o] Winter is coming Sym will teach that style. I guess I'll have to wait till next spring then.

RE: Redwing 30cc Sbach Build
 

I started off as a thumb flyer but one of the oldvet'sat the field stayed on me about my finger flying style, after a few months of flying I started practicing on the Sim with my index fingers also and I just got use to it. Now if I just try and use my thumbs it feels weird!:D

RE: Redwing 30cc Sbach Build
 

Fly heli's and you will find that you need to use both thumbs and your first finger...I learned the hard way. But learning to use thumb and fore finger made me a better flyer.

RE: Redwing 30cc Sbach Build
 

All the Competition Flyers That I fly with, fly with the thumb and finger method. They have suggested regularly that I change my ways but to do it on the Sym. Once the flying season is over I'm going to change my ways. By Spring I should be used to it.

Last year I crashed 5 planes by pilot error because I was pushing to hard to learn to fly. This year I crashed one plane because I forgot to plug in the ailerons on one of my electrics. No pilot error crashes this year so far. The Sym has also thought me maneuvers first before I tried it on a plane. It is a lot cheaper to do things on the Sym.;)

RE: Redwing 30cc Sbach Build
 

You sound a lot like me! the first year I started flying I think I went trough at least 5-6 planes. 2 trainers, a pole cat racer, a Lanier Edge 540 (50cc), and a profile!! Only one of which was amechanicalfailure, the others were just plain ol dumb thumbs. I was doing stuff that I shouldn't have been doing, but I did learn to fly pretty quick that way. After that I didn't crash as much, I just started slowing down and keeping my planes a tad higher in the sky.

the other day I went out to the field I took the MX2, I had put new servos in the wings but for got to check and see if they were going the right direction. upon take off I did all my flight checks (but I was just going through the motions). Found out in the air that my ailerons were backwards! I got the plane down safe but I broke the prop in the process... It pays to slow down some times and make sure that everything is correct before take off.http://www.rcuniverse.com/forum/js/f.../thumbs_up.gif

RE: Redwing 30cc Sbach Build
 

Yup that sounds just like what's happening to me. I've had my ailerons reversed also.

Since my last unplugged aileron incident I go through a check routine before every flight. Same thing over and over again. I should write it down and check it the way we did on full size planes but I'm to lazy. I'll probably kick myself the next time I crash because I forgot to check something. Check lists are good.

RE: Redwing 30cc Sbach Build
 

Yeah, I was a F-15 crew chief in the air force, and if I missed something like that who knows what would happen to me!

RE: Redwing 30cc Sbach Build
 

A little history trivia: The reason the Air Force developed the concept of the "Check List" was that during the development of the B-17 they had their best pilots test fly the prototype. During the first flight the plane rolled inverted and crashed with no survivors. The preceding investigation showed that even for expert pilot the new aircraft was so complex that the crew could not remember the entire pre-flight procedures and during takeoff they forgot to set the flaps in the correct position. Even with a crew of three the B-17 proved to be too complex to be flown only depending on the pilots memory of all flight procedures. I feel writing down a pre-flight checklist for the specific airplane/model we fly is an idea well worth the time it takes to write it down. And it will save us a lot if coins.

RE: Redwing 30cc Sbach Build
 

It's funny, I was just thinking about this.  I have my "packing list" as well as "Pre-flight Checlist" printed out and laminated so that I have several copies floating around.

Packing list to avoid frustration of driving to the field only to have to go back home

check list, so I don't take off without my ailerons plugged in (ever again :)

This is what I have

Radio
Batteries charged
Wings
Wingtube
Wingnuts
Canopy bolts
Toolbox
gas tank
voltage checker
sunglasses

preflight-
Check voltage
Hook up ailerons
wingbolts tight
fill tank
check all flaps


I'm just curious about if this covers pretty much everyones needs, or if there are things you would add to the list.  Do you think it's possible to make a basic list that covers all necessary items, but is not so overly detailed that most pilots have to remove 1/2 of it?


preflight checks
hook up

RE: Redwing 30cc Sbach Build
 

Hey guys, I pretty much got my Sbach ready to maiden other then the wheel pants. DLE 30 purrs like a kitten. Only issue I have is CG, Manual said nothing about it so using this thread as a base I set it at 12cm from leading edge at root. It took 9 oz of lead to get it there, must say the thought crossed my mind that for that 9 oz maybe I should have went with adding weight with some return and put a DLE 55 on it. Anyone else have this balance issue with the DLE? Batteries are as far forward as I can get them and still have access to them

RE: Redwing 30cc Sbach Build
 

Hey folks...

I'm thinking I'm going to be free of taking care of sick doggies soon and I've been eyeing the Redwing 50cc Sbach.

I've got some limited gas experience, but it's been on planes that didn't demand a lot of (electrical) power to run the servos so I've done fine with a pack for the receiver and one for the ignition.

I'd like to also move up to a 2.4 radio rig, but I have no idea what I might need in the way of electrical components to make sure I don't pull my power supply down too low and force a system reset. I've been doing some reading, but most of what I've read assumes familiarity with the various system components and how they work together.

Could someone with knowledge of these onboard power systems provide as simplistic as possible explanation of what components I would need to set up a dual battery system for my flight electronics and how to set them up?.

Also, should I consider using the same system with a regulator to power my ignition, or should I stick with a separate system for that?

Thanks in advance for any and all your help with this.

Oh and BTW, if this is not the right place to ask these questions, please accept my apologies.

RE: Redwing 30cc Sbach Build
 

Your check lists looks short and concise, It should be very helpful for any pilot to write his own check list based on yours and then add any items that pertain to their specific models. For example heli pilots and electric fliers may need different items. By the way the before trip to the field check list is very useful. I have left several times without wings, gas or most important the radio, and that's no fun.

RE: Redwing 30cc Sbach Build
 

You forgot to load the plane and canopy. I think Old Tom might have forgot one of those one time.
Bob

RE: Redwing 30cc Sbach Build
 

had the plane but no Canopy.[X(]
Bob has great eyes and now I see he has a really good memory also.:D

RE: Redwing 30cc Sbach Build
 

In my experience when you invest the money on a large 30% or larger bird is worth the money to go redundant in all systems. Take in consideration a large plane (50 cc or larger) can handle the weight penalty and it have enough space onboard for these safety systems.

If money is no object my choice is to go redundant on batteries and set up your servo power control and delivery on one of the new Power Expander systems in the market. The most bulletproof systems will have dual batteries (A123 LiFePo prefered) packs, dual battery switches, one for each battery (Fail Safe switches preferred), connected to a Power Distribution board. If you use A123's or NiMh batteries which have a 6vdc output there is no need to regulate their voltage. When using LiOn's at 7.4 vdc you will need to use a regulator or a Power system with a built in regulator.

The advantage of most Power Systems versus just a Power Expander is that besides including the regulator onboard they provides supports for dual batteries and have full battery protection where if a battery pack looses a cell or shorts it will be isolated and the good pack will continue to power the plane. The unit also supports an optional failsafe switch which, when used, reduces the weight versus using two heavy-duty switches. Additionally some provide an optical engine kill switch and all of them feed a clean filtered voltage to the radio receiver. You may run a separate ignition pack if you like or use a Battery Eliminator Filter control to provide ignition power. Be aware that if your primary (receiver power) supply is 7.4 vdc or you use an ignition that can only handle 5 vdc you will need an Ignition Regulator to handle that load.

From then on money is the only issue. Many of the IMAC and IMA pilots include redundant receivers and power supplies, where one receiver controls half of the flying surfaces and the other receiver controls the opposite half. Any of these systems configurations will work the same with 2.4 Ghz receivers as well as 72 Mhz band radios.

For additional information please see [link=http://www.smart-fly.com/Products/products.htm]Smart-fly[/link]. For a real good reading on this subject look in the October edition of Model Aviation magazine on page 35 for an article by Don Apostolico (from Don's Hobby Shop fame) with extensive information for big birds redundancy and safety systems. I believe this is the third on a series of articles from Don published in the AMA's monthly magazine.

RE: Redwing 30cc Sbach Build
 

One thing I would ad to the preflight check list is checking for direction of flying surfaces.

Hi Fhm

TJ set up the 50cc sbach for me and did a build video. He did an excellent job of it, and you can see exactly his set up here
http://www.youtube.com/watch?v=GGUXHGyg3v0.TJis a hell of a pilot and one of the nicest guys Iknow. I'm proud to have him helping me out like this!

I put it on my channel, so you can click on each step one at a time

as far as the plane goes - It is the BEST 50cc plane I've flown. It is ROCK solid in harriers, and on landings it looks like a full scale red bull plane slowly descending for a landing. I've never seen anything quite like it. The wings just don't stall.

Does everything exceptionally well. I honestly thought it was going to have coupling in knife edge, but it's one of the straightest knife edge planes I've seen.

I know this is coming from me, but let's just say I am EAGER to show you video of this one. I've only put about 5 flights on it, and i have to go out of town, but hopefully next week I"ll get some video and get it cut up to put online.

Let me know of any questions you have (or post them here, these guys are a WEATLH of help and info!)

Thanks so much for the info airtech.
