Does anyone still have or ever flew a Cox Crusaider Stunt Trainer?

Post  coxcrusaider on Tue May 17, 2016 10:56 am

I was going through my basement and I found an old Cox Crusaider Stunt Trainer. I don't hear too much about this plane and model. My dad only got it going once though and he didn't break it in properly. I just am wondering if anybody still has one or ran one at one point.

The Crusader was a fun airplane to fly. When Cox reintroduced the model in the 90’s, I was a regular at the factory buying replacement parts.  Money Toss
The reason was because I was flying two at once and trying to work out a “mirrored” aerobatic routine.
Needless to say I pile-drived numerous models.
I used to fit my Crusaders with Killer Bee .049’s and 5x3 propellers. But the stock engine is simple.
With a quick cleaning and rebuild you should have no problem running/flying the model.

Ok interesting. Mine was before the 90s and the lines were so twisted I cut them at the d-handle and untwisted them onto a steel sanding block.

That line is dacron. You can probably get something like it at the sewing and carpet section of somewhere like Michaels, Hobby Lobby, or maybe even Walmart. If you want to get serious with it, go ahead and get some fishing line that is braided gelspun polyethylene. Spiderwire, and Suffix are the brands I use. Spectra is the industry name for the exact Dupont(I think) product. It's hard to tie knots that won't slip, so look up how to tie it on YouTube. A Palomar knot is popular with the C/L crowd, and I think it's the AMA approved knot. Do not dot it with glue. If you use Dacron, pre stretch it before use. It's good to do a pull test anyway with the plane on the handle. Just making sure it won't take a side trip joy ride Lol. The old swirrely(sp.) green handles can break in flight. Ask me how I know.

Keep us posted.

Oh. I have some braid on an ice reel that I am not using.  I will never use glue. Glue never works on metal. The only thing that keeps metal together is other metal. I used a taunt line hitch to attach the Dacron to the bar. I never could tie the Palomar knot but hey. What test line do you use because I might just ditch the old lines. The taunt line when the working end is pulled, tightens. It's a slip knot designed for securing loads.

20# Power Pro is what I run for lines with .049 engines. Bright high viz yellow can be had on ebay. The brown/tan color is easier to see in green grass than the green/black color. All three disappear in half dead grass though.

Pop onto AMA's site and in the documents is CL rules which specify the 5-turn uni-knot, doubled. They also do not list less than 20# lines for any purpose. The knot is easy, just follow the instructions (the instructions are in the Power Pro package too) Doubled just means to fold the end of the line over so there are two strands being tied as one.

To make lines identical tie one end of both lines, then stretch them out together and mark the lines. Include the mark in the knot. The lines should then be within 1/4 inch of each other. In reality within 1 inch is typically able to be adjusted for.
