Seagull glasair sportsman
Got this beauty for Christmas and can't wait to get building. Anyone build this model up? What was your engine choice?

I put a saito 115 like the size and power fit perfict .Bought the floats to that why I got it .Very nice plane just don't like the covering starting to sag

put a saito 115, like the power bought the floats to very nice plane just don't like the covering it is starting to sag.Saito is a sweet motor small and a lot of power .More and more impressed with seagull airplane would like a 377 arf

How's the fuel usage with it and flight times.? I was thinking of maybe a dle 20? Electric would get very expensive for batteries at this size.. All I have is a bunch of 2200 3s.

Definitely getting floats too.

still building the plane should be done this week I hope , have run the motor in my p51 as long as you don't fly the hole flite at full throttle should not be to bad. Dle 20 should work good I would beef up firewall just put epoxy all over mine

well that saito 115 might not be a good idea hard to line up pushrod for throttle,but I got it.Now working on the wing slot for servo arms are off ,easy fix

I'm still toying with what to power this bird with.

Maybe electric, saito fg21 or 17, or a zenoah, dle... I like the sound of the saito but not the price. Got any build photos of how that engine looks? Looks to be plenty of space in that cowl. It's pretty large.

engin fits fine will have to cut the cowl for the head of the fourstoke

A pic of my engine install and with the cowl on. Use the 90 manifold and you'll be cutting less. :)

Mickel where is your throttle servo had a hard time with mine. Did you buy the float set with yours

#12 bladebender Jan 22, 2013 04:15 AM

Hi folks

Just picked up a Glasair Sportsman 2+2 75-91 ARF
by Seagull.

Wondering what other engines people have used. The Saito 115 sounds good except for the price. I am considering a gas 20cc engine. Anyone have experience with the xyz 20?

Wing loading is in the 35oz per sq foot and wondered how it flies. MAN article makes it sound like a floater, but that weight made me think it would fly heavy.

My first impression is that the airplane is very well made. It has a sculpted appearance with lots of compound curves which means it was probably labor intensive compared to some ARFs out there. Control surfaces are pre-hinged with pocket hinges and move very freely while keeping a tight fit against the wings and stabs. Control horns are composite and are to be epoxied into precut recesses in the control surfaces. Flaps included. Control rods appear to be carbon fiber. Separate servo for the tail wheel which is pull pull. Covering will need some iron and heat gun attention, and is not as good as some I've seen, but not too much. Two pilots included.

Seeing you live in a more temperate climate, I was wondering if you have maidened your Sportsman yet. The Saito looks nice in there.

Hoping to get some more dicussion going on this plane. Sort of surprised that not much is being said.

Blade Bender

could you discuss the problems you had with the throttle hook up and what you did to get around it? I'm still considering an engine.

Looking at the assembly manual, it is not clear what is holding the wings on.
