hi flyers
i build recently a piaget shockflyer.
so tough on EPP
hoping a test flight today
will post videos soon

is it the tech one shockie from sai uncle

yes

What is EPP ?
Good luck, and keep us posted with pictures !

EPP is Expanded PolyPropylene,
its a great material, unbreakable hoevewer hard is yr crash, but it needs lot of reinforcement as it is very flexible..

Is it like the material used for this plane - zero crash capability virtually http://www.electrifly.com/parkflyers/gpma1275.html

Epp is actually EXPANDED POLYPROPYLENE. Follow the link ------> http://www.epp.com/ for more info. cool stuff for parkflyers. EPS (Expanded polystyrene foamhttp://en.wikipedia.org/wiki/Polystyrene) is also good. XPS (Extruded polystyrene) is the flexible foam found usually inside packaging cases, cd covers etc............

I also felt that the foam is a bit too thin (keeps the weight down, I guess) as compared to the 5mm foamies that I have been using.

Other than that, it is a nice plane.

i flied piaget today. it hovers really well
but in normal flight my plane is going up,
i have given 0 downthrust. how much do i give ?
also im having a problem when in high alpha i am giving full aerelons , aerelons are moving but there is neglegible response,
do i need more torque servos ? i am using  gms rcforall DYS servo.

pls tell me

Are you sure the "going up" problem is not just an elevator trim issue ?

About low aileron response, I think people are not responding because the question is not clear.  What exactly are you trying to do ?  Are you trying to do something like a torque roll from a hover position ?

If your existing servos are able to give you enough deflection of the ailerons and hold them there, you should not have this issue.

Basically, it looks like we need more information before people can pitch in with suggestions.
