This may be a dumb question, but are there any bad tendancies when landing the EF Yak, like tip stall? I had about 25 flights before having my Yak destroyed in a collision with a tree. Am now building a new one, and had no trouble with first, except nervousness about landing. I am not new to this hobby, but I have found, if I am going to get bit, it is usually on landing and usually during the first 10 to 20 flights. Don't ask me to describe the tree incident, it is to painfull to relive.

This is my favorite landing plane of any I have had. It has no bad tendencies when landing....and never ever tip stalls. Now if you get it going slow enough on approach, any plane out there will eventually stall. This plane does it at a very low air speed, and very gracefully. Landing in wind gusts is usually very risky with any plane since it can drop in a split second. I have found this plane to be very good even in those conditions. It's an awesome landing plane.

Joe,

Well put, I concur! Thanks for all of the advice leading up to me deciding to get the 88" Yak, you were a big help to me.

James

I like the way mine lands. Not very scary at all. In fact I tend to land after every flight I like it so well.
Thanks

Yup lands superslow !! Any plane will eventually drop a wing,but this one will only do it just before it drops out of the sky.. Like Joe says if the wind is gusty keep a bit more power on,not much just a click or two of throttle trim.

id say other than my 110yak this 88 was the easiest to land too, the 88edge was very easy too, floated for sure, but that one took a little longer to slow down, sleaker frame, not a big deal just got to get used to it, these yaks, especially the 110, i can cut my downleg final short, bank it in even from a good altitube, cut the power and she slows up right on the runway, its pretty cool

The Edge is def. sleeker so faster airframe. It will slow to a crawl you just need to fly it to the ground more then the Yak.. I'd love to see a 100cc Edge !

Thanks for telling me about the Edge. I would not be at all surprised if EF is not already thinking about a 100CC Edge. They apparently really put a lot of time and effort into the 125" Extra, what a beautiful plane that is! Maybe someday that is the direction I will go.

What kind of battery set up would you need for the 125"?! I think a DA 170 with pipes would end up cheaper in the end,hahahaa!! I'm friends with them on Facebook and look to see if their showing anything in a 100cc Edge almost every day!

Frank,

Have you seen this video? http://www.youtube.com/watch?v=zzholvMsJuY

I am pretty sure that if I build the 125" Extra that it would be gas. I like the sound of the twins, esp the 150CC on pipes.

I just bought some additional batteries for my 50CC Yak. These are 30C 5800 6S packs which give me 8-9 minutes with a good reserve. They now cost $66 each and it takes two of them to fly. This will give me 8 flying sets. Assuming 200 flights conservative out of a set of batteries that works out to 66 cents per flight + 1 -2 cents to charge the packs. Just two and a half years ago I bought a single battery for the EF 58" Extra and it cost me $265! Things in this hobby are really changing fast. The gas engines are also getting lighter and more powerful so it's win win no matter which way you go.

Actually I just found out the DLE has a 170 for $1049.00 from Valley View RC.. I'd still have to sell all my stuff to get one of those flying,but it would be sweet !!

I believe that was the 100cc Extra that EF is working on? He was flying it with a DA120 in the video. Great video though!

Frank,

Yes, that was an amazing video, both the plane and pilot. It was interesting to me that the colour scheme on the plane in the videw appears to be the same or very similar to the 48" Edge.

Thanks for the detailed advise on landing. Now if I can keep the new one out of the trees I shouldn't have any worries.

i asked a little while ago and they do have that 100cc extra coming out, no current plans for a 100cc edge curtis said, but i would think eventually they would, they are obvisously here to stay for the long haul

...and will give the poeple what they want...eventually...

S & S

S&S,

My best advice with regards to trees is to always go over them when possible! It can be difficult sometimes to determine how far away the plane is relative to the tree and then with a larger plane your brain tends to think that the plane is closer than it actually is..it's a scale thing, so just be extra careful when you move up to a larger plane! I have hit two trees in the last 10 years, total destruction on the first hit and almost no damage on the second thankfully. On the first crash my observer was watching and thought I was well in front of the tree I ended up hitting so was not alarmed and didn't say anything, it can be hard to tell. Best to just fly over them!

James,

My sentiment exactly. Afterward I realized the scale issue, but at the time it was a real shocker. All of a sudden, there it is in the tree, 40 feet up! Fortunately, about an hour later, it dropped to a lower branch and was retrieved. But right after impact, I was completely astounded by what happened. It wasn't until the next day that I realized the plane's size had mislead me into thinking it was in front of the tree. I have to laugh now at the (human) error. Live and learn!

Thanks again, Greg (S & S)

My new EF Yak54 88" , #1152 on the wing root rib. Rcgf 62 series 2 on ES Composites ES55G pipe. A123 2300 mah x 2ea batts on RX / servos via a DPSI BIC (gives mah used dual batt support and high/low volts and amps , time run etc) , servos all new in box Hitec 5945's except rudder with Hitec 7955. A123 1100 mah on ignition with dropping diodes.
Maiden flight any day now if the wind gives me a break.
Have balance set at centre of wing tube for initial maiden flghts , will probably ditch the DPSI BIC when i get some data on mah usage to lighten up a tad. Came out 18lb 4oz with 1/2 tank of fuel (20 oz tank) , so i think i'm in the ball park weight wise. Checked all incidences with Aeroperfect digital meter and all is 0 , 0, 0. with 2 deg right thrust.
What do the experienced EF users think? I've not had one of these before , but have had 4 other 50cc Yak 54's from other manufacturers , so will be interesting to compare.
Thanks , Leon.

Looks great. Your weight is right where it should be with the pipe and extra fuel. Mine is 17# 13.5 ounces with no fuel. It has the DL-50 with stock 3.4 ounce muffler and Kavan air tires, no wheel skirts. Yours will probably be right where mine is when you ditch the DPSI BIC. The CG is not as critical on this as other planes out there. It will fly very neutral at almost any CG in its range. Mine is about 7.25 inches and flies great.

Leon,

I think that it will probably be love at first flight! I don't know of anyone that has not said positive things about this plane. I concur with what Jo said about the CG. I have flown mine a bit tail heavy and nose heavy and the plane flew fine in both trims though certainly slightly nose heavy is preferred. Just do everything you can to insure that the engine is reliable before your first flight and that your controls are setup correctly. Let us know how it goes for you.

Thanks for the encouragement guys , i have been looking forward to this particular plane for a while after reading all the posts and seeing most of the video you guys have posted.
Don't know what happened when i uploaded the pics though? Last Yak 54 i had was an SD 30%, was my favourite plane till it went in from having the RX whip antenna being shadowed by the aluminium tuned pipe i installed (was on JR 9X with 36mhz at the time) , was doing a knife edge circle and when the belly of the plane was in front of me , went into PCM lockout , low throttle and did the prettiest knife edge into the deck! Was fine for over 70 flights before i wen to the pipe. Oh well , live and learn i guess.
Went to the A9 about 7 months ago and am still coming to grips with the expo vs the JR , which was a lot nicer IMHO.
This one is to replace it , if it flys better than the SD i reckon i should be in Yak heaven!
Still waiting for a Secraft double lock rudder arm for the servo , the current one uses an ally hub with an SD ally arm bolted to it which is probably o.k. , but i still like the double lock arms. Won't stop me from a maiden , provided the gale winds we've been having here abate.
I'll report back after the maiden flights for sure and give you my opinion if you like , not that i can 3D as well as some of the pro's on here...
I know this has probably been asked a zillion times , but how far back are you guys running the C.G. from the wingtube centreline? I'm right dead nuts centre with a 1/2 tank of flying juice?
Thanks again , Leon.

Leon,

Sorry about the radio problem on your SD.. My Yak is electric powered. For my final CG it is setup so that with batteries installed and holding the plane from the wing tube, the nose tilts down slightly so it is just forward of the wing tube.

I believe the CG starts at the center of the wing tube and ends at the rear of the wing tube. I think that distance spans 3/4" but that's all from memory (6.75"-7.50" from leading edge at fuse).

leon i think you will like this one a bit better, i had an sdyak, the 80cc size, it was a close second to this 88yak as far as being my favorite, they both were excellent flyers and enjoyable, it was close like i said, but the sd was second none the less, and that was slightly bigger and more powerful, so comparing this to the sd50cc you may notice even more of a difference, keep us posted...
