Hello Everyone, I am quite sure that my interest in chainsaws is very different than everyone else but I hope to obtain some feedback from experienced people in this forum.
As a hobby I build and fly ¼ scale WWII fighters and chainsaw engines happen to be perfectly suited for powering these birds. Most of the time flywheels are shaved and prop hubs have to be machine but outside of that stock chainsaw engines can be bolted right in.
Some of my work can be seen at http://photos.yahoo.com/bc/rcbird12...rder=&.view=t&.done=http://photos.yahoo.com/.
The reason for this post is to obtain some feedback regarding which chainsaw engines, between 60cc to 100cc, are best suited for this purpose. The most desirable characteristics are as follows:
Compact design, in close muffler and carb configuration.
Magneto is bolted directly to the engine.
Low and smooth idle.
Smooth transition from low to mid range and from mid range to high
Ability to mount a flat back plate for attachment to a firewall.
There are a number of manufactures in the hobby that take stock chainsaw engines and make new crankcases and electronic ignitions but they also increase the price of the stock motor by 50% to 100%. Common motors used include Sachs and Quadra’s.
Any suggestions regarding engines that you feel would make a good power plant for a large-scale model would be appreciated. If you have something that you would like to sell me between 60cc to 100cc please let me know also.
Thanks
Norman
