Default RE: Extreme Flight 87" Yak 54 - Build & Fly

Has anyone had problem with the DA50 not pulling fuel. When I tried to start engine for the first time, I noticed no fuel was being pulled into carb line from clunk in tank. Removed and checked all plumbing, seems okay. I took a 9 inch piece of Tygon and put about 2 inches of fuel in the line so I could try to see movement. With this test line connected to carb fuel input, I turned prop with throttle open/closed, choke open/closed. The section of fuel in the line moves back and forth about 1/2 inch, but the net is no movement towards or away from carb. I have disconnected the line from crankcase to carb, and found the crankcase is sending pressure outbound and into the carb. I cannot detect any obvious leaks anywhere in the mounting of carb to engine. Anyone have any ideas?

Hey Todd, try opening the needles several turns. I've had the same issue before and this took care of it. Just remember where the needles were set so you can return them to their factory settings once the fuel begins flowing.

Yes.
Call Horizon and tell them you want a 9303 or a 10X.

Funny, I lost too many planes with futaba radios! I'm not flaming here, just pointing out that every company's product has its share of problems...
lost one plane, sent the radio & rx in
lost another plane (same radio & rx) sent it in again
lost third plane and engine...went directly to futaba and demanded a new Tx & Rx...got them and never had another problem...sold the radio and went JR...haven't had a problem since. This was several years ago with a Futaba Super 7. I am no longer for or against Futaba, I just figured I'd stick with what has worked for me for the past 8 years.

I ordered a DA50 from Don's Hobbies friday and they had it in stock and I should have it today or tomorrow.
Just need to decide what muffler, get a prop, rec. and bettery set up and 'll be good to go!!
Don't know if you are a heavy builder or what you plan to add to the plane (smoke, nimh's over li-ions, cockpit etc), but if you are planning to build light while still having some performance, I would go with the Hyde silencer. It's total weight is a little over 13 oz. (with header), but it is very quiet and produces AT LEAST 200 rpm over any other muffler, except a tuned pipe. I have one and just did a weight figure for my plane. I will be under 15.5 lbs.

Ya - I agree. I want that 14MZ. However, I need a trailer first. Most of what Wayne does is on a mix anyway. I'll bet the 14MZ can out mix that 10X, then I will become a really good pilot! LOL

Looks like my motor is sold. Now time to buy the servos.

Okay, here's what I was looking at....

The 5645MG's produce 168 OZ/In of torque at 0.18 sec. Manual only says that you need 125 oz/in of torque. I can get 4 of these for $219.96 w/ free shipping from servo city.

The 5945MG's produce 180 oz/in of torque at 0.13 sec. I can get four of these for $359.96 from servo city w/ free shipping.

Is there a reason to spend an extra $140.00 for 12 oz/in or torque and 0.05 sec of time? I can't think of a reason but maybe there is...

I'm planning on going with Fromeco batteries and switched regulators. Don't like the idea of having to unplug the batteries due to the drain on the batteries but figure I can live with it. I really couldn't make out the smart-fly system. Maybe I'm too stupid

Thanks guys!
Kevin

www.donalds-hobby.com has the 5945s, 4 for $300. The 5945 is a much tighter servo and it centers much better. Either will fly the plane though. I went with the 5945s as I have used the 5645s and wasn't impressed with their performance.

Great prices. Last time I checked Donald's he was the same price as servocity. Need to start checking around much. Still a $80 difference for the 4 of them. I have some 5625 but haven't checked them out yet.

Kevin, 5645 are good, but slow! go for the 5945 all arround! insted of using a very expensive servo on the ruder get 5 5945

I dont think that the yak needs more than a 5945 on the ruder!

I really don't like the 56 series. Weigh more and don't center as well as the 59 series. I've got 5945's in the yak and they work great! Why skimp? This is a $2500 plane. Why not spend the extra $$ and get the better servo???

Drew, please don't tell my wife this is a $2,500 plane. She would kill me... Good thing I got most of the money together by selling everything I had in electrics so she can't add it up!

While on the radio issue I would like some comments on the Hitec Eclipse 7, anyone else using this? Other than being limited to 7 channels, whats wrong with it?

Joel, nothing is wrong with the Eclipse radio other than most people by the time they are flying planes this scale / expense has already upgraded their radio to much larger radios with more memory.

Given enough "Y" connectors you some match boxes, you can fly the yak with a 4-channel "non-computer" radio.

The first cost estimate I told my wife was $1600. If I knew up front how deep I was going to get into this, I may have changed my mind. I haven't flown mine yet so I'm still not sure how thrilled I am spending this much!

The fact that it'2 only 7 channels and if it's not pcm its worthless. I guess you could get away with a matchbox for your elevators to open up a slot in the receiver, cuz you will need at least two slots to plug in batteries, 2 for ailerons, one for rudder, one or two for elevator, one for throttle, and one for ignition cutoff. You will need a matchbox on the elevator to run all this stuff...
Again, if it's not PCM, scrap it!!!

I told my wife the plane would cost $650. She 'bout lost it, so I stopped right there. I didn't really lie, as the plane was $650[:-] I just purposly forgot to mention the $90 spinner and shipping ($55), and the engine ($550), batteries & regs. ($200), servos ($450) a new 9303 ($600), and misc. stuff ($300-$400). Good thing I used Paypal money and sold some stocks to finance it to keep it on the down-low!

I use an Eclipse 7 and really like it... With the Spectra module I don't have to worry about who else is on my channel... I just tune to another frequency, change the xtal in my Rx(s) and go fly... It is a PCM Tx...

Let's just say I have had some issues when mixing channels with it... Like for dual elevator servos... If you have you EPAs adjusted to anything <> 100%, the slave channel has a delay in actuating, causing it to lag behind the master channel's servo... Maybe it's me, but I don't think so...

You could Y-cable / matchbox your way to using the E7 with the Yak, but not for me... Think of the amperage that would be drawn through the single Rx channel connector when using Y-cables on the servos this airplane requires...

I will always keep my E7 around as a backup Tx, but I bought a 10X to use on bigger (i.e. more expensive) airplanes...

Oh, BTW Drew, thanks... My wife walked in as I was catching up on this thread... She walked up just as I was reading your reply on "not skimping on a $2,500 airplane"... Her first question, "you spent HOW MUCH"!!!! In a panic, I did the first thing that came to mind.. I kinda sorta lied...

*new can of worms*

There is nothing wrong with flying this plane on PPM (FM)
I have flown SEVERAL gassers without using PCM.

PCM is not less suceptable than PPM. They just handle the noise differently.
Again,
No right or wrong. Use what your comfortable with.

I wanted to say that but more people will take Wayne's word for it than mine

I finally got to start on my build this evening

From my understanding on the issue is that the FM doesn't have a fail safe where the PCM does. The PCM and FM both will glitch at the same time but it's less noticable with the PCM because of the failsafe. Just repeating what I heard.

Two batt's and a cutoff are not required. There are 2 slots opened up.
