RE: Extreme Flight 88" Yak - Build and Fly
Nice videos. Makes me want to go fly me Yak. Thanks for the inspiration.

RE: Extreme Flight 88" Yak - Build and Fly
Well I finally got the permsion from my wife to go ahead and buy the 88" yak. :D Before I did I wanted to find out what length extension and how many I need for the servos. I know it said it back ealier in the thread when I was reading all 198 pages but can't seem to find it now. Thanks for the help.

RE: Extreme Flight 88" Yak - Build and Fly
2- 36" for elevators
2- 12" for ailerons 1- 12" throttle 2- 6" for the aileron channels in the receiver, so you can remove your wings and unplug at the extension, not receiver. Larry |
RE: Extreme Flight 88" Yak - Build and Fly
If you want to remove the stabs I think you need 48" extension.

ORIGINAL: Spectre1 ORIGINAL: Mokken ORIGINAL: xtraflyr Hey Guys, I hate when they don't update you about the forum.. So I figured I would post and get me back in the ring.. Ive been flyin the poop out of my Yak. It seems with the cooler air temps like 49deg. the DA pulls like a truck out of a hover with the DA fitty on a 22x8 Mejzlik. I did my first Kedge Loop today talk about nothing special happining!! Had a nice death slide today from about 300' to 20' off the deck.. This is so fun to fly,I can't get enough of it!! I havent flown anything else since Sept.except some stuff my Dad has to fly. Im glad I gave it a good look over today. I found the where the Tuned Pipe mount sits on the side of the tunel cracked the balsa that it mounts to. My Da seems to vibrate some and I know the prop is balanced. Can it be that the low end is to rich still? Shakes enough to make the canopy look like its gonna break,rattles it some. What cha think? If I put some pressure on the top of the cowl the rattle stops. Cya..

Go into "settings" and under "Thread subscription preference" choose "Notify me whenever a message is posted" I'll bet you have the following chosen: "Notify me once per thread until I visit the thread again" I may do the dowel Mod too. Do you have a good pic of the mod? Spectre Cya. X |
RE: Extreme Flight 88" Yak - Build and Fly
Just a thought I have used this before but just a little silicon caulk really light typically takes all my vibration away. Using in on the tabs keeps it out of sight and reduces vibration as well.

RE: Extreme Flight 88" Yak - Build and Fly
The back of my canopy has been cracked and glued several times. I saw a plane somewhere where they just cut off the overlap but it didn't look as nice as the factory.
So I ca glued the crack one more time then took canopy cement and trowled it on with a popsicklie stick in that bottom corner of the canopy nice and flat but complete in that bottom corner, both sides. I let it cure for a day and backed it with masking tape (for now) The tape insures that it won't stick in the hot sun when the canopy is bolted on. I only have two flights since the mod but it appears that it will be stiffer to keep those cracks from returning for a while. Next I will go to the canopy tabs in the front and do the same with the canopy cement. |
RE: Extreme Flight 88" Yak - Build and Fly
My Canopy has its share of problems as well,
Here is what I did to help tame tne "rattling" of the canopy. First I used blemderm tape around the front top of the canopy. This help to make a nice snug fit. I put on just enough so that the overlap from the engine cowl covered it. Next I lined the bottom of the canopy w/ 1/8" wing saddle foam tape on all four sides. It helped to quiet down the rattling. As far as the cracking of the over lap from the canopy to the fuselage turtledeck, I cut off some of the overlap, a little more than a 1/4" rounding off the bottom corners. It did start to crack so I took some very lightweight fiberglass cloth and backed the corners on the plastic canopy and the back canopy former w/ thin CA. I let it over hang the canopy plastic, let dry and trim off access. Never had a problem since. |
RE: Extreme Flight 88" Yak - Build and Fly
I used blenderm on the turtledeck under the canopy with no problems. 78 flights to date.

RE: Extreme Flight 88" Yak - Build and Fly
Are you all having to make a larger hole for the axels. I got the 3/16th dubros like the manual states and the hole is too small, did you all drill it out or did I get the wrong axels?
|
RE: Extreme Flight 88" Yak - Build and Fly
Yes - needed to drill the gear but used the PSP Titanium axles. ORIGINAL: decoy26 Are you all having to make a larger hole for the axels. I got the 3/16th dubros like the manual states and the hole is too small, did you all drill it out or did I get the wrong axels? |
RE: Extreme Flight 88" Yak - Build and Fly
love this plane to peices but have one prob....
having probs with my DL 50 & KS 1060 tuned pipe (vess 23b prop) being to peaky/ punchy, ive measured the header lengh (TBM 25mm drop) from the exhaust flange to start of pipe and it comes out at 12 1/4 inches now i ve read somewhere that it should be 11 inch with this pipe but my problem is i have a nice knuckle on the end of the header which i dont really want to cut off so my question is do i have to or can i shorten the pipe lengh and by how much ?? cheers guys |
RE: Extreme Flight 88" Yak - Build and Fly
Nick, I would not cut anything. lots of guys are just running that set-up right out of the box. Vess 23B is a great prop. Might want to fine tune the neddles a little, or use a throttle curve on the power band. I have the ES composite pipe on a DA 50 and it has a slight burst of power in a certain part of the band but is managable in hovers. I know that Chris Hinson is running a KS 1060 pipe on his and it performs great.
|
RE: Extreme Flight 88" Yak - Build and Fly
i think tbh it could do with shortening as the pipe is peaking, its horrible in the prop hang i litterally have to think about moving the stick and she punches out and pulls vertical plus if you leave throttle stick in position the engine dies off :eek:
theres throttle response and there is too much throttle response lol, would be nice to get it a bit smoother ;) |
RE: Extreme Flight 88" Yak - Build and Fly
I had the same situation and took quite a bit out with throttle curve.My B60 and ESpipe were at first peaky or to me the combo seemed to continue to rev and it took awhile for me to get used to.I have gotten used to it some and the throttle curve adj. really smooothed things out for hovering.
|
RE: Extreme Flight 88" Yak - Build and Fly
I switched back from the 23b to a 23a to get the rpm slightly higher in hover. The motor seems to like it there just a little better and I have an easier time holding hover. By the way, DA50, MTW 75 pipe, header from DA, NO mods.
|
RE: Extreme Flight 88" Yak - Build and Fly
I have the Da50 with the 1060 and its great. My throttle is linear. I just kind of blurp the throttle to keep in the hover. Took a little time to get use tobut it's no problem now. Im not a 3D guru by any stretch, but linear works for me.. Im also using a 22x8 Mejzlik if that matters at all...
Hope the weather stays ok for tomarrow. Their talking mid 40s and 5mph winds!! BUUURRRRRR!!!!! Cya, X |
RE: Extreme Flight 88" Yak - Build and Fly
i started out at 14" long from a DIY header kit from DA,on a 58gx and was getting 7400 real smooth throttle.i cut header 1" at a time and now down to a 12" header and gain 150 rpm's with a ES pipe but just starting to see throttle getting peaky.and this is with a biela 24-8 carbon.
i tried a bolly 23-8 what a joke it had it ripping at 1/2 throttle. ENJOY! |

I did the dowel-mod to the canopy. I used 2 short pieces of CF. Works good and the canopy is nice and tight.
|
RE: Extreme Flight 88" Yak - Build and Fly
Joe,
I like your mod! Good Idea[sm=thumbup.gif] |
RE: Extreme Flight 88" Yak - Build and Fly
Thanks!
|
RE: Extreme Flight 88" Yak - Build and Fly
I'll be sure and do that mod myself. So the addition of the two dowels stop all the canopy vibrations.
|
RE: Extreme Flight 88" Yak - Build and Fly
So far
