Status: offline 		Hey guys I,m wondering whats the best rudder setup to go with on this plane .I see that some have used the offset 4" servo arm and crossed the cables while others have used the straight arm and the cables are not crossed. I know that this will start a fire storm of differnet ideas on what is right. I'm just getting ready for my plane to come in and I'm buying all my stuff to put it togather. Mark your input would be welcome here. I have looked at the info on SWB web site and as per there info I think the crossed cable system would be the best scenario. On my two 50cc QBs I have crossed the cables and this has resulted in the best setup as there is hardly any cable deflection during full travel where the cable exits the fuse. Just woundering what servo arm setup will be the best for the 35% Extra QB??

Status: offline 		Lazy Eight: I use a 3" SWB offset arm on one JR 8611a @ 6.0v for the rudder and have no problem doing knife edge loops. There may be a slight bit of slack on the "push" side but I don't think it makes any difference. Beside, SWB doesn't show a straight 3" arm.

Just so you know, I think they call it a 1.5" full arm, which is why you didn't see a 3" arm - 1.5+1.5=3

Congradulations on your addition to the QB fleet! Be sure to clue us in on the build and equipment choices - I already see the power expander and assume single rudder servo...what else? Mine is currently engineless, but will have a new powerplant soon and I will probably be posting the conversion in the next 3 weeks or so, depending on work.

My red version showed up today. It is beautiful! Can't wait to get started but work always gets in the way. So, I'll be in the parts purchase phase for a while. I'd like to work the weight down into the mid 25-lbs range. However, I like the quiet of canisters. Will the BME 115 on canisters get me there if I use carbon parts. I've read most of the posts on this forum and it sounds like it will. I'd really like to try the ZDZ 80 but this would just about make the balance impossible. Any ideas? How would the 80 do power wise? With one header and one can, the weight might be better.

Status: offline 		Mine was 25.5 pounds with the BME 110 and stock mufflers and CF tubes, gear, and tailwheel ass'y. I also removed a good bit of wood from the hatch assembly, ran only one rudder servo, no powerbox or matchboxes or choke servo, no switches, so to speak (They are the pull-pin type that come with Fromeco regulators and are virtually weightless), and no pilot.
Now, mine is the older version and the newer ones are supposed to be about 1/2-pound lighter because of higher quality balsa, so you can say that my setup could have been 25 pounds, even.
With that said, the 115 is a few ounces heavier and the cans will add a pound, which would put you at 26 pounds, at least. However, the cans may move your CG forward a bit, so the size and weight of your batteries might be able to be adjusted.
To get mine to balance, I had to hang my 2400mah Fromeco off a rail on the engine box to put it almost right behind the spinner backplate! The other two 2400's were at the very front of the engine box. I also had to use a standard, non-lightened aluminum spinner and Mejz prop.
If CG suddenly is not an issue due to the lighter tail components, you can save about 4 ounces by going with a CF spinner, another ounce or two with a wood or PT prop, and a good half-pound by going with dual 1320 lipos on the rx and a single 1320 lipo for ignition (and I believe the Falkon ignition can handle the voltage, so a regulator may not be needed). This will get you in the 25 pound range, but 24 would be hard to do. The only other placed to save some weight would be one servo per aileron, but I would be leary of that...
I can tell you that, in terms of wingloading, 25.5 pounds is pretty darn light, and that 115 will have no problems pulling it if you are not up in the nosebleed section like I am!

Status: offline 		Hey is anybody running smoke on this airframe?? Looking for some ideas. I have been working on and off on my 260 through the week and must say this is one fine kit as is all the other AeroWorks kits I have built. The QB line is one of the best wood ARF's on the market. I have been doing alot of reading trying to find the perfect setup for this plane and I think the setup that Joe Hunt has done on "Down on the Deck" looks hard to beat. I'm buildin
