Drank the kool aid........3 big boxes showed up today......freaking psyched

only thing left is to decide on is if i'm gonna run Y's everywhere or go with a smartfly eq6


initial assembly fills my whole shop..... damnnnnn

Congrats on the plane. Just my .02 but I would try my best not to run any Y's.

i use y's on ail after i program them, seems just fine to me

lxcoupe

My Feedback: (34)

This is exactly why I'm still undecided.

My set-up will be something like this

7985's on the ailerons y'ed as in left side plugged in to rec and right side y'ed and plugged into separate channel

7985's on elevators plugged in normally

5955's x2 on rudder y'ed and plugged in normally.

I have a programmer.

I will also be running dual lipo's through a 6 volt reg and a bat share

Or I can get a EQ 6 and make everything neat and centralized and not have to Y anything. I have some time to chew on it.

I think there may be a 3rd option here, but I can't find any info..... I could link 2 spektrum receivers together and run straight to each channel. Is that even possible? I though I remembered reading about guys doing that with big planes when the DX-7 first came out. To me that would be the best option because of the redundant rx's.

You must love those Y's..... until you lose your $4000 plane. Why not learn to use your programmer and a 9 ch reciever?

It's not that easy. Have you tried that yet?

My Feedback: (74)

I just dont like Y's becasue it is another point of failure. Had them on my first big plane that I bought from another person and had nothing but trouble. I was always having some weird crap go on with them.
I got rid of all the Y's and all of my problems go away.

There is always more than one way to do something. All I can give you is my expereinces and opinion but what it boils down to is how you want to run your plane. If Y's feel llike the way to go to you and you have always had great luck with them. Then that is what I would go with.

I think Y's are the simplest setup for the ailerons. I use the Hitec Twisted Wire Heavy Duty Y's. The other options (matchboxes, power expanders, etc.) could be a potential failure also. The Y's won't bottleneck the power any more than a matchbox.

lxcoupe

My Feedback: (34)

I'm not sure I understand your logic. I know how to use my programmer. I'm going to have to use it no matter what direction I go. A smart fly and a match box is just a really spiffy Y. You take both leads and plug them into one place then plug that lead into your RX. That makes it a Y correct? Maybe you are thinking of a servo reverser? Besides I only have 7 channels to play with. So I have to make due with what I have.

diamondave

My Feedback: (29)

7 channels is one more than you really need anyway, i have a 9ch futaba but going to switch to the 2.4, the 7 channel is all i can afford at the time, the cost difference to the 8 or 14 isnt warrented to me(until i have a warbird with flaps and retracts), i see no problem with using the 617 and my Y's on my ailerons, like you said, any other electronic part added is another potential failure, i had a smart fly igntion kill fiber optic deal go bad on me, i took them out of all my planes now, back to basics, KISS, a y harness may have less of a chance to fail, its a simple part, no other extra crap or circuit boards or anthing like that, almost like any other lead you have to use, i might not Y a Y with multiple servos on one just for current reasons, but other than that im comfortable using them for my wings for sure

plaster93

My Feedback: (20)

just program your servos as needed and get yourself a power expander or a emcotec mini and use a lead to each servo, no y's. This way each sevo gets its own power and not sharing power through one lead. Each channel is buffered though the expander and filtered. If a servo goes bad it wount affect the other one as it would on a y. Read into it on these forums. A wealth of info on here!

Very Sweet Charles!! I hope one day to get one of these Yaks. My 88" will have to do for now,unless I sell it and my 74".Then I should be right on..

Thanks

I sold my 88" Yak when I got the 110". I still miss it, but one of my best friends bought it so I can still fly it from time to time. The 110" is a sweet plane and it's no more trouble for me to transport and assemble than a 50cc.

I'm finally getting close on my plane. Spent the day setting up linkages and programming the servos. I learn a ton everytime I step up in size and complexity. I'm Y-ing the ailerons and rudder servos. That is what Chris suggested. And what's good enough for the MAN is good enough for me. I'm running a DX-7 with the AR7000 receivers. Read that as 2 - AR7000's. Ailerons will be on Aileron and AUX-1, and Elevators will be on Elevator and AUX-2. Both AUX channels plus throttle will be on the second receiver. Separate switches and A123's for each receiver. Something might fail, but less likely with the dual systems. First time for me with dual receivers and anything big enough to have dual servos on any single surface. 7955's on the wings and 5955's everywhere else.

I am ready to go with my second one. I sold the first and now have the color scheme I wanted. On this one I decided to do a few things to save a little weight and ended up shedding 1 pound without getting too crazy. They don't need to weigh less at all but it's something to do this time of year. Came out at 27 lbs 10 oz with gear fairings, carbon baffle, 5" spinner, A123 batteries, stock mufflers,etc... not too bad I guess. Lighter Kavan wheels, Ti axles, lightened #1 former, Powerade fuel tank, hardwood rotation dowels, etc. Ended up balancing on the back half of the tube with all the gear right around the cg too! My first had the batteries under the rudder servos for the same balance.

pfoot, that's really sweet! Love the CF baffles. Got to find myself a source for either CF plate or CF cloth to fabricate something. I'm on the slow side building this one. Had to finish building a house, move, unpack, explore the garage, build shelves, benches, save up and actually buy the stuff to throw into it. That's my story and I'm sticking to it.

Thought I was going to fire it up today, but didn't quite get that far. Plan to do that tomorrow.

I used .5mm for the baffle and cut a few 1/2" wide doublers and glued on the backside to stiffen it along the edge. The baffle is attached with screws from the inside. I cut short pieces of wooden dowel in half and glue them into the cowl lip on the inside and that gives a nice flat surface to attach to . Got the carbon from Protech Composites.

ive been using a vess 26b since the motor was new, i just bought a menz 26-10 for my super80 coming in, but im going to try it on here for the heck of it 1st, looking at the 2 the vess appears more beefy, its 2ozs heavier, not much, the tips are a tad longer even thought they are both 26, and the vess is kinda swept at the tips, the menz is totally straight, on the plane the menz looks kinda dull, guess im used to all the shinyness and logo's on the vess, but i really want to see what it does to compare, if i like the 26-10 more than the vess i may splurg for a mejslk for this yak then, that would look sweet im sure with all the blacked out stuff and big cf spinner, maybe even the biela black with the yellow tips, not sure which performs better though, mej or biela? anyway hope to get out this weekend but the weather may not cooperate from what they are saying at this point

here is a pose pic

i found the 26B performed better than the 26-10 menz for me anyway, tached about 200 more on the ground and felt better in air, quicker response, pulled out from hovers better, all around more enjoyable for my style of flying, i could maybe see using a 26-10 for imac, carried a bit more speed when throttle down, climbed at a nice steady speed, but not sure if id spend $90 for a carbon fiber one just to use for imac, at least not unitl i am at that level where this would be exclusivley for sequence, now its all around fun plane for everything i do

Hello diamondave
I liked the Biela 26x10 on my Super ZDZ80 and KS-95 canister better than Mejlzick 26x10. The Mejzilck 26x10 spined 300 RPM faster than Biela and it's a better 3 prop at 6700 RPM but the biela 26x10 at 6400 RPM is better IMAC/3D prop for my flying style (60% IMAC, 40% 3D).

I just got back from the flying field today and I was only able to get one flight on my 110. I'm glad I carried my Extra. After 59 flight I've had my first malfunction on my Yak. I was practicing one roll circles and one roll figure 8's. I was about 8-10 min. in to the flight completing a figure 8 on the final turn inverted with the rudder pegged to the right and it flew wide. I bailed out to avoid flying over the pits. I could tell something just didn't feel right. I'm a firm believer in if something doesn't feel right get it on the ground. After switching it off, I grabbed the rudder to roll it back into the pits and I noticed the rudder felt like it was binding. It took more than the usual amount of pressure to turn it. Everything looked fine on the rudder and tail wheel so I pulled the canopy. I like an idiot had to get my hands on everything. It didn't take long for me to realize I could get a good burn if I held onto the sides of the 8711. The bottom plate was warm but you couldn't hold the sides. After letting it cool down, I powered the plane up. Now the servo is noisy and you can easily stop it from turning by holding the arm with your fingers. I'm glad to have my plane piece and the servo didn't lock in full deflection. The gear slop had been getting worse and it has chattered since day one. I have a 7950 Hitec on back order with plans to replace the 8711, but I was hoping it would last until then. I already have 2 7955's to go in my EF Cap so I'm going to use them for the rudder. I don't know if I would feel comfortable using one servo on the rudder again anyway. The worst part about switching it to 2 servo's is relocating my receiver. I made all my own extensions and cut them to length for the receiver to be mounted on the servo plate. I think the 8711 has plenty of power to 3D fine, but I don't think it's strong enough for IMAC. I was using a 4" arm because the 4.5" wasn't available when I got the plane, but the 4" arm would give the servo more of a mechanical advantage over the 4.5". I've done many knife edge loops with it and I haven't felt any blow back until today.

T. Bob,

I may be wrong, but my logic is it would take more power to pull the rudder at 80mph than at 10mph.
