Status: offline 		I finally received the wood kit for my Carden Thursday night! Somehow I managed to just drool over the box that night and put off any actual building until Friday. So since then I've managed to get the motor box assembled, the fuse sides built and sheeted and joined to the motor box. So far everything has gone together very easily. The fit and finish of the wood parts are outstanding. You can really tell Dennis puts a lot of time and care into each kit.
Caroline has told me I can expect the foam parts in another week or so....I hope they come sooner rather than later! I'm going to run out of the things to do to the fuse quickly! If I can stick to my schedule, I should have this finished by mid-april...just in time for the flying season to begin in Ohio!

I've got a DA100 for it and KS cans on the way. I'm leaning towards Hitec 5945 servos all around, though that decision doesn't need made right away. Futaba PCM rx, emcotec DPSI for power distribution, and Fromeco liIon's will finish off the electronics.

I've been documenting the build on a website I setup just for this. If anyone cares, feel free to check it out. http://www.flagcityflyers.com



I can't wait to get this thing in the air!

Status: offline 		Looks Great ,
I picked one up partially done 2 years ago -fuse built -stabs and vertical fin, and I have FINALLY gotten around to finishing it.
I decided to use a single 8611 servo for each wing; my theory is that I can reduce some weight
on the tips of the wings and I won't need a matchbox .
I had a 35% cap 232 and it was fine with a single 8411 on each aileron. As of today,
I have the wings almost ready to go into the vacuum bags.
Good Luck with your build -- you will be happy with the end result. Cardens are first class airplanes.

Status: offline 		You know, I'm glad you brought up the single aileron servo question. I've been debating the exact same question. If I can use a single servo in each aileron and on the rudder, i figure I can save about half a pound in weight....but the question that keeps nagging in the back of my mind...can I do it without risking flutter or stripping the aileron servo AND keep crisp performance. Right now I think I'm leaning towards two servos for the safety and redundancy factor. I'd love to hear some constructive feedback to this.

Status: offline 		Looks awesome and I like your website. I too am building a Carden, the 35% Edge 540. Check out my thread, it might help a little. I'm also struggling with the number of servos per aileron, but I think I'm going with 2. Another reasons is I'm thinking of extending my ailerons for more authority while torque rolling.

I'm looking forward to following this thread.

Status: offline 		Hey Steve,

I have been reading your thread on the Edge....it's looking very good! Keep the pictures coming!! Especially close-ups of how you're mounting/aligning the wings/stabs. I'm interesting in learning about any potential hang-ups I might find with mine.

So far I'm extremely impressed with the kit....it's so simple it's brilliant!

I can't wait to get the foam parts for mine so I can start giving this box some shape.

I also like the idea of extending the ailerons for 3D. I may do something similar. So that would be another reason to go with 2 servos. Hmmm...decisions decisions....at least I still have plenty of time to decide.

Status: offline 		my style of flying influenced my decision to go with 1 servo per aileron, as I avoid
high speed where flutter may be issue
the other changes I will do, will be using a harder balsa for the aileron
leading edge --to make the aileron less flexable across its span
and the linkage hardpoint will be in the center of the aileron

Status: offline 		The fuse and stab foam parts arrive Friday. I've had the vacuum pump running nearly non-stop since. The main wings are supposed to ship early next week. Here's a pic of the fuse so far. Starting to look like an airplane!!

Status: offline 		did you extend the ailerons at all, or are they built to plans? I'm toying with the idea of extending them a couple of inches to help with 3D manuevers. If I extend them, I will most likely use two servos....might do it anyway just for the piece of mind.

Status: offline 		i.m almost finished covering my 35% extra. da100/kscans. 2 5945's on ailerons and 2 8611,s on rudder. carbon fiber tube to save weight and i hollow the cores after sheeting. only building left is to glass the hatch after the canopy is glued in. bob teseo

Status: offline 		THe only issue that comes to my mind using one aileron servo is the twisting issue. Not sure how Carden Ailerons are built though...
I had A single 8611 on my rudder on my 31% Edge, about 18.5 lbs..Knife edge performance was OK, but for a 35% i can't imagine it being good...But then again, what do I know?

Status: offline 		For a 35%, a single 8611 on the aileron will be plenty. The only thing you are going to have to watch out for with a single servo is flex in the aileron. If the aileron is stiff (say, in a composite arf) then there is no need to put two high torque servos in the wing. I don't know enough about cardens to say whether the aileron will flex or not, but a single 8611 would suffice in the power department.

Status: offline 		I consulted 2 different manufactures of large foam/balsa sheeted type airplanes
they said it will be ok as long as the mechanical advantage for the servo is maintained and
the ATVs are set up for max travel -this increases servo resolution
the aileron is not going to flex
and the problem of flexing is only on a fully balsa built-up wing/aileron
I will attach a picture later of my 35% extra with a single servo
but if you need peace of mind by all means do what YOU think is best
thats what I did !!!
