GP Extra 300S build
I am considering ordering a GP Extra 300S 60-90 kit. Intend to use it with a DLE20. This isint my first build but I am not an experienced builder. I have built a GP UltraSport 40+ before- well, I half built it and then a more experienced builder completed it for me. So I have a few questions
1) Is this a fairly easy kit to build. Since I built the US40+ a couple of years ago, my building skills have improved and I have got all the tools now (dremel etc)
2) I want to 3D this airplane. What are the mods I need to make? Can someone point me to the page where the mods are listed?
3) What are the critical areas I need to fibreglass?
4) How many rolls of monokote will I need?

Hi Ameyan
I built up this kit a couple of years ago and it is not a particularly difficult kit to build and the instructions are excellent.
As a kit you could build it stock i.e.e without any modifications and it will fly great - but will not be a good 3D performer.
To do 3D would take a fair amount of modifications and or replacement of parts, which if you are not sure about doing is probably better left until you have built up some more kits - or scratch built a plane or two.
It is however a superb aerobatics flyer and I am sure you will enjoy the build as well as the flight characteristics.
Follow the instructions regarding fibreglass reinforcement the only area I reinforced with glass was the ABS cowl along the inside seam. The wing is strong enough as it is without the need to glass it.
2 - 3 rolls of covering should do it depending on your colour scheme.
Let me know if you would like some build photos and I will dig out what I have There area couple of good build threads going have a look there too.

RE: GP Extra 300S build
Hello ameyam, I too just got one of these kits last week & will be using the same engine in mine. I also want to do 3-d with it. From all I have read on this, it needs to loose some weight to do 3-d well. I am still investigating this. I can keep this thread up to date as I find out things if you'd like. I will subscribe to this thread to keep up with your build. good luck. I was just trying to upload a picture or 2 and things just are not working right now, I will try again later. Bill
