RE: Seagull Yak?
Just keep it as lite as possible,as lite as you can get it.I swing a 18-8 prop.The G 20 isn't going to cut it......They make some new REAL strong 20-30cc gassers now,I love my Super-Tiger 2300 ton of power,uses almost no fuel(about half as much as my Saito 150 per flight) as is very lite.My plane R.T.F is 9.5 lbs.Yea and tint the canopy black and loose everything that was under it.I used carbon-fibre gear for strength and low weight,Brian [sm=bananahead.gif]

RE: Seagull Yak?
I would think the G 20 should be plenty of power. You should be able to find video of this set up on You Tube. A DLE 30 would be way to much power. I agree with the gear issue, but the stock gear is very maliable and will save the fuselage during a hard pancake landing; they happen! Rudder moved to the tail also sounds wise with the weight of the G20 and ignition. I would use a battery eliminator for the ignition to save weight. Carbon wing tube would be worth while, but not necessary in the begining; my aluminum tube developed a bow from some hard landings. Also go with a 90 oz metal gear servo - Hitec 5665, Futaba 3050 etc. This plane is a great flyer - Good Luck!

RE: Seagull Yak?
They are all correct in the G20 as it will fly the plane,I was just concerned about the weight issue.put the rudder servo in the tail for-sure and mount your batteries as far back as possible but........How much do you want for the N.I.B plane? is it the new style or the old one? You an tell by the amount of wash-out in the wing,the angle of the rear stab and the 3 inner root ribs on the wing.The new plane is also 1lb lighter R.T.F.You can tell what plane you have by the type of tree the side fuselage formers are made from,is it a yellow-brown or a lite-brown? The difference in flying is nite and day... Brian [sm=thumbs_up.gif]

RE: Seagull Yak?
When you say 5.5 do you mean 5.5 inches back from the leading edge at fuse? I was told 23/4 inches and I am tail heavy.
How do I properly check? my maiden scared the hell out of me and I am nervous to try again. Want to make sure I got the CG this time.
Thanks

RE: Seagull Yak?
Faspplane, thanks for the feedback. My Yak has a Saito 120 and I was measuring back 7-8cm on the wing at the fuse.. Should I measure back 5.5 inches and try that.
The guy that built this and sold it to me showed the (Factory) 7-8 on wing tip, and it appeared balanced.
I am new to the sport and appreciate any advise,
Rick

The most often quoted CG is 5.5 inches back from the leading edge at the fuse, which is approximately the back side of the wing tube. The factory location will result in a tail heavy plane and a likely crash.

RE: Seagull Yak?
Maiden flight on mine yesterday. No issues, only had to add some up elevator trim. Built as manual suggests
except for the pilot. He is too ugly. Yellow & back color scheme
Powered by 'XYZ 26 gasser' with 16-8 prop. Plenty of vertical. 1/8 right and down thrust, balanced at 5-1/8"
at wing root. Set up controls per manual, low rates 60% with -30% expo on elevator and ailerons. Used Futaba
7C-2.4G radio with S-3010 servos. 12 oz tank= 20 plus minute flight time. Batteries were 4.8 receiver pack
1100 mah and 6 volt 2000 mah for ignition. All up weight was 10.4 lbs.
Flys very solid at speed and slows very well. Landed in 10mph direct cross wind with slight rudder input and
throttle just above idle. No tendency to dip wing tip at slow speed.

17 flights so far. I did relocate batteries to bring 'CG' to 5.5 inches from leading edge,where it meets the fuse. . I also took all the expo out of elevator.

RE: Seagull Yak?
The 'XYZ' will swing a Master Airscrew 16-8 prop at 81-8400 rpm.
(Still on first gallon of gas and not yet leaned out.) If you can get a
similar prop to spin around these numbers it will fly well.

RE: Seagull Yak?
Thanks, I have mine set perfect doe 3D, I have it slightly in front of the spare 5" on spot...does great flat spinns and knife edge. I think I will need to go to a Saito 180 or a Gas 26cc to do serious 3D (Torque rolls and rolling harrier) very hard to do with my current setup.
It is a blast for acrobatics!

RE: Seagull Yak?
Hello everybody. This looks like a cool plane and I'm considering it as my next project. I really want to get into gas engines and I'm curious if this would be a good plane for a gasser. I'm debating between a zenoah g-26 or a DLE 30cc. I want something that will hover at half throttle and not hesitate to climb out. Suggestions are appreciated.

KEEP IT LIGHT!!!! D.L.E 30 way to much,plane will never be a true 3d plane due to high wing loading....My 30% yak weighs only 4.5 lbs.more,but has twice the wing-area.I get 8500rpm out of a Xoar 18-8 prop,engine is a 34oz. Super tiger 2300 (23cc),plane R.T.F is 9.5 lbs..Does great aerobatics ,but slow 3d,no way .

I know what you are saying Capital, I was just wondering if anyone found a compromise that works well with this plane. Maybe I should rethink my plane if I want to get a gasser.

Go with one of the cool 72" that are out there now,Pilot,or Peak models.They sell combos with the DLE 30,that's my next plane.I was just trying to keep you from wasting your money on a plane that won't do what you want... I got a least 100 flights on my Seagull Yak and it is a good plane,it is just limited in it's capabilities.I will sell you mine RTF if you really want one....CHEAP!!!

RE: Seagull Yak?
The info is greatly appreciated. I will definitely give those 72" models a look. If I'm going to go gas I may as well make it worth my while.
