Hey drbyrnes.....
If your planning on wanting to do the 3D type flying , the DA-50 would be the best bet between those two motors. It does weigh less than the G-62 , but also has more of a "3D type" power for that type of flying. The G-62 is an awesome engine , and has proved itself over the years to run like a swiss watch , but for 3d.....there are better choices out there. |

I'd probably agree with the above.

You have to remember that wing loading is extremely important as well for 3D flying. DO NOT install a DA-85 on the front of a 30% yak.....to much power that you will never use without sooner or later damaging the front end of the yak , and probably the motor itself. You couldn't run a 26" - 27" prop on the 85 like what it needs because of the clearance i believe. You would be running around a 23-24" prop....which makes the 85 waaaayyyy under propped , and god only knows what type of RPM's you would be getting out of the motor. |

I disagree with this. Lanier put 50-80cc on the box, but should have left 50cc out of the equation because this plane is bigger than most any 50cc you'll ever find. Its really a 80cc plane. It has tall landing gear legs and it will easily clear a 26" prop as many people fly this plane with the ZDZ80.

There are other 50cc-55cc motors out there as well , that you might want to look into as well. Taurus 52cc , 3W-55 , MT-50 , the newer extreme power area 51 motor and countless others. Some come in lighter than the DA 50 and some with quite a bit more power as well. Hell.....if you really wanted a lot of power , stay light , and have a good 3D performance motor , you should look into the Berelli 366 ( 60cc i believe.
Don't get a DA-85 for that Yak , it's a waste of a motor , and that airframe won't be able to hold up to that type of power for to long. It's made for an aircraft for around 21-26lbs. |

Someone in the thread said the Laniers are heavy. This is not true concerning these Yaks. They were simply miismarketed as 50cc planes when they were in fact 75-80cc planes. This plane has a short 87" span but a lot of chord (1466 sq. in.) It's about 86" long. This is not typically 50cc size dimensions. The plane weighs about 18 lbs, and yes that would be heavy for a 50cc ...but its not a true 50cc plane. Take a look at this YouTube video of a 87" Lanier Yak flying with a ZDZ80xi and decide if you think its overpowered? It seems to be the perfect match.
The DA-85 has more power I'm sure ... but doubtful it will ruin the plane and engine the way described. I have the 94" Lanier Yak, really nice, well built and light plane.
