The OS engine in the right photo is an LA 40S and of course intended for controlline airplanes and the other is the throttled version.
Reinoks I beleve you are confusing Cubic Centimeters with Cubic Inchs. The LA 40 is .40 cubic inches about 6.5 cubic centimeters. These engines are totally unsuited to your airplane.
I would use no larger than an LA 10 (.10 cubic inchs) and as the guys already pointed out without three channels minimum you will have no throttle.

yeah ur right...
but i get it that if i dont have 3. channenl i cant set thease throttles... i can do it on land
i need engine what i can easly kick start and what will work about 1 min or bit more
i want get my big glinder up to sky
[:@]
the max height/attlitude waht i get was about 30 m ... comon it s nothing
but i have little engine 1.5 cc
i guess that 1.7 cc is also too light for my big palne...
when i was in russia 1 guy very old and wise i guess told me that 1.5 cc is too small...
he recomended at least 3.5 cc and he poinet at blue os engine im magazine what he had withim
maybe OSMG0015 is also OK ? this thing w8 is only 130 g its 20 more than LA 10 and OSMG0015 have 2x more power
