Glinder with 4.0cc engine
Handmade glinder with 4.0cc engine ... is it good idea ? and where/how to put it ...
MY palne - lenght: about 130 cm weight: 600 g
wings - lenght: 200 cm weight: 300 g
My TRANSMITTER is only with 2 channels ( check my pofile
)
-------------------------------------------------------------------------
yeah my sailpane is pretty light so i have to put some weight to it ...
point is that i dont have this starting rubber ... what ever ... so it costs about 30 $ - 60 $
for this money i can buy an engine what can add some speed to my plane ...so by this way i can get my glinder up to sky ...
i want to put/install/iaffix engine what i can start easly and maybe use in in the future
and yea about this 3. channel thing (gas setting) what ever i have very old diesel engine without this gas thing...
but this engine is so old that i cant start it [:'(]
and im not so dumm that i cant get that i can set trottles...
--------------------------------------------------------------------------
as i red from other forums (subforums)
4.0cc is too powerful ... it will cause rocket effect lol ... whatever
but maybe 2.5 cc is ok ?
15 LA (os engine)
and if ill put it on pane nose/top then i can get ths pane up to sky ?
pls comment

RE: Glinder with 4.0cc engine
reinoks,
I'm not quite sure what you are asking here. But from reading what youhave said you're not going to be able to use that engine on your glider. If for nothing else because of the 2 channel radio you are using. You will need a seperate channel to control the throttle on the engine.

RE: Glinder with 4.0cc engine
If you look close you will see that the pic of the engine on the right has a non adjustable carb. I believe that this engine was designed for control line models. So I guess you could use it on a glider with only two channels.

RE: Glinder with 4.0cc engine
I have some old gliders that were builds of my Dads. Some of them have small cox engines mounted on the top of the wing just for getting the plane up to altitude I assume. It runs wide open like a control line or free-flight model until the small tank runs out of fuel & by then you have gained enough altitude to sail around.
The OS .40LA is much too big for this type of application imo. From looking at the plane in your pic, your plane is no bigger than the ones Dad built & the engine on these is only like a cox baby bee or an .049 I would have to look at one to be sure. If my math is correct your listing a total weight of 900 grams between wing & fuse wich comes out to about 1 lb. It shouldn't take near that much engine to get a plane that light up in the air. An .049 to .074 should be plenty I would think. Plus they will have the right type of small fuel tank mounted on the back of the engine. You don't want it to run for very long. Just long enough for you to get enough altitude for gliding right? An engine on a glider is just a method of launching it.

Take a look at these engines. I believe this is more along the line of what you would need for a light glider. I would post this question in the gliders & sailplanes forum though. Those guys will know better than I do about this because I don't fly gliders. I'm just going by what I see on the gliders I have. Those guys are into gliders though so they will know what you need.

RE: Glinder with 4.0cc engine
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.

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
