 |  advice: portable tug
Hi folks, ive posted this query at rcgroups and have gotten some response and based on that have made some "preliminary" thoughts. figured I'd post here as the bias is toward big powered scale planes so folks might have more opinions: looking for a substantive tug... minimal rigging removeable tailgroup and/or removeable landing gears capable of tugging 25LBS+ glider in the 6m range under CAPABLE hands. engines ive been told to consider too are (obvious) DA100 zenoa G62 or 80GT Evo 80GX based on these criteria, ive come up with the Top Models Pilatus Turbo Porter http://www.icare-rc.com/tow_planes.htm but with objectives and issues: which 1? the 2.5 or 3.2m - remember, PORTABLE. go with the tried and true DA100? vs Plettenberg Preadator 30-8 which icare claims "will tow 25-40lbs gliders to sky's limit"? with a DA100, wonder on both the 2.5 and 3.2m, will the cowl need to be reworked? caveats regarding making the horiz stab removeable? caveats esp regarding making the vert fin removeable? caveats regarding making the landing gear and struts removeable? i havent committed to anything and so am open to suggestions |

I would go the 3.2m, I think the 2.5m may end up being to small for what you want to do. As for the engine a DA100 would be first choice, however you may have to butcher the cowl to fit it in and in doing so loosing the scale look. An 80-85cc will fit inside the cowl alot better and still give you good performance.

The electric setup may well be powerful enough. It also has less cleanup to deal with which enhances portability and quiet operation certainly goes well with glider flying. Things you should ask yourself about that option: * How many tows will you get per pack/charge? * Can you charge very large packs at your field (is there mains power or a generator)? * Cost. The speed controllers for that size motor cost a mint. If you plan to do lots of towing in remote locations then its hard to beat a can of gas. The DA-100 is a smooth running motor.
