Links to all our online instructions

(with links to the associated product pages)

Due to popular demand we are making our illustrated instructions available online. In the online version the embedded images are hyperlinks to the larger color versions of the same picture. Just click through to see the detail. We will still include paper copies in our kits for use on the workbench but the latest versions will be posted here. We hope this helps with some of the (unintentionally) hidden details.

Thanks,
Jim - RA Cores

Pushrod How To

Here is the method we use to build the pushrods to avoid melting any of the foam. It also allows you to fine adjust them before hitting them with CA to hold them in place. We are slowly updating the instructions with this info but it might be missing from the paper instructions of an older kit.

Geoff Barber did a great instructional video for RCUniverse about making Foam-Tac hinges. The video is a bit old and uses them on a Depron plane but the method works just as well on EPP. Give it a view (or three). The one thing I have to stress is use a NEW blade. If the cut starts to pull or tear, your blade is dull. It doesn't take long for the blade to get dull. The single sided razor blades are great to use. The follow the rulers easily and at a dime a piece you can toss the dull ones.

Night Flyer How To

Rob Kallok has done a "How To" on lighting up your night flyers. People are always asking me how he does such a great job and so he put an instructional together for me. Well worth the time to watch it and you'll be rewarded with some great night flying footage Andrew Walters shot at the NEAT Fair at the end. Thanks Rob!
