GREENLEY TUG BUILD THREAD 88"

Post by Wayne Thompson » 24 Sep 2018, 23:47

Hi all

OK, so i started a build thread to keep myself motivated then the system crashed a week ago and my profile and tread vanished so i will try restart it all.

Please read the pdf to start off with and view the photos then the thread will restart from there. I have been assembling bit for the kit and then start the build, almost ready to start just need ply for the shear webs and to cut the cap strips.

Engine is a DLE 60cc twin.

There were some comments about some using thicker ply for the sides and top bottom of the fuz as well as comments about the 10mm stab / fin being strong enough without the use of the spar but this is my way and you are welcome to change to your way. to be honest the thicker ply fuz would have so much easier i think at 1.5mm i could have just got it laser cut with a 45 degree puzzle joint.

Who has commented about needing thicker ply for the sides? ALL the SD and SDD Greenleys use 0.8mm ply for the sides, top and bottom of the fuz and I can assure you it is strong enough, same with the 10mm balsa tail, it does not need a spar.
The "improvements" being suggested to you will only add weight and detract from the model's overall performance.

What you may not be aware of is that the Greenley has been continuously developed over a period of 20+ years to refine the design and improve its performance. Built exactly as per your plan they have proved amply strong enough for the rigours of towing over many seasons. It is not a "one off" design that has not had the benefit of hundreds of hours of real testing and development.

Hi Wayne

If I were you I'd stop. Think of the Greenley as a very well sorted tug just as it is. Not only that but if you ask anyone who has one its their go to hack model. why fix what's not broken!
