Serious problems with 3m 77 spray
Cap and 1.4 Cap builds...
The first problem I encountered is that it attacks the foam. Very clearly attacking the foam. Even when it is sticking, the layers are 'puffing up'.
Now a few weeks later many of the laminations I did with the 3m 77 are delaminating. While I could probably tear the laminated skins off and replace them, it's been 4 weeks now that I've been unsuccessfully trying to get parts from John for the 1.4 I see no point in going down that same path on the cap.
This plane is junk because I used 3m 77 spray.
DO NOT USE THIS PRODUCT TO LAMINATE YOUR SKINS.
Now I check the laminations I did with Elmer's spray for the 1.4, several of them are also delaminating.
I built (or tried to build) two of the 3dfoamy planes (the cap and the 1.4 cap), both are garbage and after too many emails to count I can't get replacement parts from john, so I guess I'm giving up on 3dfoamy stuff. $300 wasted.
Seems like they could be cool planes, but with it being impossible to get responses from John on replacements, 3-4 week shipping times on new models and this failure of spray glues I'm going to just have to give up and move on to something else.
Best of luck to you all.
I have lots of motors and speedys for sale if anyone is interested PM me and we'll discuss what i have.
