Aviation Models 35% Extra 260 Build Thread

I like how the two piece cowl allows the easy access to the engine. The one I flew in China was awesome so this should really meet your demands. Looking good.

Hey Propstriker,
I'm putting together one of these birds as well. I agree with both you and Torquen on the pros and cons of using standoffs for the powerplant. A little more vibration but better cooling. What did you use to secure the hinges (epoxy,etc) and did you pin them? I've always used Robart hinge points with excellent results, no failures to date. Also I found that at extreme throws the rudder horn and elevator(s) will bind.
Did you have this problem? Anyway, that color scheme is great!

Lookin good. I would recommend one thing though. Don't use those wooden dowl spacers to space the engine. I have seen many, especially long one's like that, crack down the the length of the bolt from vibration and causing the motor to come off in flight- not a pretty sight. I recommend using alluminum spacers instead. Good luck.

I too wondered if that motor box was shortened, then stand offs added. Larry, sorry I did not get a build going on mine.... I am packing up and I believe we have the house sold and headed for Nashville. Good thread, get r done.

Polyurethane Glues such as Probond or Gorilla glue has always given me excellent results for securing hinges. As far as the rudder horn interfering with the elevators at extreme throws, Keeping the rudder horn total width at 3.5" or less will prevent that from happening....it`s close, but you can get full down elevator travel with no binding.

Thanks Propstiker,
I'll keep that rudder horn under 3.5" for clearance. I'm powering mine with a 3W106b2 with cans. Also using Power expander and Turbo Reg. I really like the workmanship on the plane and the two piece cowl. I'm looking forward to your build thread so get to work and post lotsa pics. thanks.

Git-R-Dun Larry !!! Lets fly it this weekend

[warren cross]

Propstriker,here is trick I use for wooden dowels standoffs,stand it on edge,on a piece of wax paper,start putting THIN ca on the end grain untill it comes out the bottom(you can see its progresson the out side as it goes down),Ive used this on many planes and to this date NEVER had on split,this includes 100 thru 150 size motors. Try it u'll like it.

Hey Warren, thanks for the Tip...These were made from oak, and I`m machining some aluminum stand-offs as we speak..

Hey Brian!! this weekend might be a bit early!!

[STR8HUCKIN]

Ive been using nylon standoffs with out any problems.

[Propstriker]

Machined a new set of stand-offs from 6061-T6 Aluminum....whatchathink?

[JeeUm]

Very nice indeed.
