Can you comment more on what is a good economical way of reinforcing the nose? - Do you think removing the prop and spinner and plugging in Toothpicks will make it much better? Does changing the screws make effect too?

I think it will be OK, and everything looks as straight as the eye can see. It flies great. The heat treatment works wonders, but I wouldn't expect it to be quite 100%. I just had to sand 1/16" off the front of the canopy to get a perfect fit.

The photo shows how I stiffen the nose with three strips of 1/8" plywood, one on each side and one on the bottom, glued in with White Gorilla Glue. The strips have embedded #4-40 blind nuts to replace the OEM plastic nuts and anchor the three stainless steel bolts that replace the original watch-maker's screws. The combination of the ply strips and the larger bolts make for a very rigid and strong nose.

As you can see the motor I am using is not the original. It is a Turnigy 3530-1100. The prop is a Graupner CAM 11 x 6 on a 50 mm aluminum hub. This combo provide increased power so the stronger motor mount is needed to keep everything flying in formation.

Kaptondave, would you mind sharing some pics of the ESC/battery area of your radian? Looks like you've got a custom mount for the ESC. Does that extend back to the battery as well?

Wow - that looks pretty interesting. So you have actually screwed bolts through the plastic + EPO + plywood strps. What bolts are you using ?

I am hoping this will not require me to install a new motor or prop and will work with stock setup?

Sorry, no pictures handy. The plywood piece with the holes in it is the forward end of my custom battery tray. The 1300 mah battery is at the back of the tray, just out of the picture, held down with a Velcro strap. The Turnigy 30A Plush ESC is under the battery tray. You can sort of see the red cover through the holes in the plywood..

The bolts are #4-40 machine screws. I use stainless steel ones but regular steel will work as well. To install them I used a 1/8" drill bit to enlarge the holes in the plastic cowl and drill through the foam and the plywood. Actually the plywood strips were drilled and fitted with the blind nuts before gluing them in. If you don't want to mess with blind nuts use regular nuts with nylon inserts for locking.

This reinforcement method will work just as good with the stock motor.

I like that setup !

Thanks,

thspoq, have you done any stiffening mods? I can see a quite a bit of flex in the tail when you make turns. The tail wags side-to-side and the rudder twists.

Ill be honest, that radian (ive got 2) is my beater and it has been through hell and back. The only stiffening mods that ive done were running fiber rods down the length of the fuse. I probably should do something to the tail before she gives, haha.

Thanks for the good rating!

That video took around 30mins to edit. I only have 1 camera (go pro HD) and 1 mounting position (fwd or rear). It does suck trying to compress a ton of really good videos into a 4-6min video but in the end its usually worth it. I cringe when I see others post unedited videos, editing really makes the videos that more enjoyable
