You may have already seen that thread [link=http://www.rcuniverse.com/forum/m_3082557/tm.htm]Poulan 25 from FL trimmer[/link] where I described entire conversion.



The truth is, that first I had and idea to build 1/4 scale PZL1-9 Wilga 35/80, next I got plans from UK. Now when building the fuselage I had to stop at the firewall to make sure the engine will fit right. As it is not a high performance plane I thought that cheap weed whacker will do just fine. Actually it does much better than I expected.
I estimated the weight of this 1000 sq inch plane will be 13-15 lb including 4 lb engine, and because it has very short nose Poulan fits just fine. I had to scale original plans to 90% as I wanted to fit the fuselage in my truck with 6ft bed. So it is about 68 inch long and 98 inch wingspan.

Anyway the engine is finished now, ready to run so I'm going back to the plane. It is fun as original plans sucks and I use them mostly as a general view coming up with my own engineering solutions. I'm just so happy I could get away with 50 dollars power-plant (including new muffler).
