I have got a small 3d plane Komacro(wingspan about 40 inches 42- length. I am looking for an engine for it. All up weight less motor and fuel is 850g (30 ounces). I want it to hover and pull out. I was thinking of a magnum .28, mds.38, os 25la or mvvs .28 OS max 25fx would be the best but it costs too much over here. Maybe any other choices?

32sx


All motors listed are great...OS is the best for something liek that

i was under the impression they were using LA 15's!!!!!

The lighter the setup the better it will fly. Phillybaby is pretty smart , so I would go with his opinion

See ya and good luck

if i was you i'd do more looking, tho i'm pretty sure they stay away from havier ballraced engines sticking with small plain bearing engines. Ask Cartman, hes the man that knows about that plane

Would it have unlimited vertical with os max .25la?? I don't have money for os 32sx or 25fx .They cost more than 150$ in Poland!!!!!!!!!

the SX are bearing engines and therefore heavy.
if i'm right even the 25la is too big.
there are threads on the Komacro, use the search feature and you'll find you never needed to ask this question

My model has been stiffen up. From my experience it can even handle this .32sx. At first it had been covered with paper and now I have changed it to supershrink polyester film. The whole model is very stiff and will surely handle a much bigger engine than a .15.
So phillbaby just check the weight- 30 ounces less engine and fuel!!!!!!!!!!

Boogie, try the "Norvel" line manufactured in Russia. Lightweight with lotsa power. These things scream. The .25 is 9.02 oz. (250 kg) and the .15 is 5.7 oz. (161 g) both around $60.00 Sorry I didn't get back to you on that other project, it's on hold for now. Later, Joe

Oh that's bad. But I hope that you will come back to the project soon. I know how you feel. I also have many projects on paper. RIght now I have to finish a flying wing, a 70inch trainer glider for a friend and a slope 100inch glider. I alos have a .25 UCD on the building board- just started building it. Then I am going to make 2 F3A models to compete with them. And then are two lon projects- a 4m glider and a 100inch b-29.

I have just bought a .28 mvvs engine- paid 55 bucks.

now thats allot of projects!lol

I wish all my projects were planes. Work is is such a distraction! Joe
