Committed to the build now, got the plan, got all the bits from Coolwind, UHU contact on its way, cleared the table off, off to the printers today to get the plan blown up. First attempt at a scratch build since moving from my big workshop with a house attached to it a year ago. Believe it or not this model will be built in the same room I built my very first KeilKraft glider in 53 years ago! I hope it flies better than that one did! It's cost is about 110% more.

I think my print shop enlarged the plan too much. Can someone give me a measurement to check? Say mast length, or main fuz length?

Hi Tim,
Just measured my plan and the mast is 11 inches the fuz is 26 inches from the firewall to the end of the rudder measured along the baseline.
Hope this helps.
Dave.

Thank you for that, it all checks out so it must be my lack of making a jig saw.

Anyway its my first time with EPP and its not going well. I am struggling with sticking this together with UHU Por. I have tried all ways to get it to take and it wont. It air dries OK in about 10 mins, house is nice and warm, I have laminated the fuz together and left it clamped under a board with a weight on for 4 hours. I took it out the clamp and it just fell apart. All the parts are warped and bowed. Its genuine UHU Por as well, and I got the EPP from Coolwind. I must have got some kind of contamination on the foam as I tried the UHU on some Depron and that worked OK. I have built several large FPV foamies with the same glue and they where OK. So I will need another sheet of foam and have a go with epoxy or Elmers polyurethane glue. If that fails I'll give up.

Hi Tim,

My plan shows 7" from top of the fus at the mast to the head pivot and 24" from top front bulkhead to rudder hinge line.. See the pics

The other lines are those for my SE5 version

Hi Tim

That's odd... My method is...

Cut parts, run glue over surface of both pieces being stuck from tube in tracks approx 40mm apart. Spread evenly and well over whole surface with an off cut as a spreader.

Leave to dry over night completely, note it curls while wet. In the morning it has returned to being flat ... Then align and press firmly together ... Done

Originally I was using the glue as a wet joint with pressure. Always have poor results and often bent. Rich put me right to use the glue as impact adhesive and no Isues since...

Steve

Must admit that I have never used EPP......but.. I have always found it a good idea to remove the surface of any type of foam with course grit paper to help it it key together.

The let it dry overnight works, but you have to get the fit right first time. It reminded me of how I fit laminate sheet with evo stick on a worktop. After glue drying I lay wood dowels on the surface then the sheet on top of the dowels, line up and slide the dowels out one at a time. I'll crack on with this and if it looks Rubbish get another sheet from FD.

The EPP I gave to Tim was from my personal stock (to build a Whippit) and it came from Flying dog, the pack was opened on the day Tim collected it, 1 sheet removed and handed over.

So don't understand why Tim is having problems

Not your foam that was the issue Malcolm.


I know what the issue was. First problem was I tried the new UHU Por Impact adhesive which was not a good plan. Second, Once I followed SJ's tip and let the UHU Por dry completely it was fine. The issue was that with 2 different glues curing at different rates caused the fuz to dry like a banana. So it was a basic novice EPP builders schoolboy error, not the product. The remedy was to cut lots of slots in the inside bend and push in spacers made from MacDonalds coffee stirrers, until it was straight.
