About the cleanest, unmolested, dirty, previously ran Cox engine that I have ever disassembled, and that's around a hundred. No fuel residue in the tank and the reed was pretty clean.

Looks great Bob! Fortunate to have the green spinner along with the prop hoop. The windscreen looks great also.

R/C Driver must be a previous owner add on? New stick on decals made a big difference.

Hey Robert, Is that "tab thingy" between the prop and drive-plate an OEM part?

There's something similar on my little DC Merlin diesel.. but I question its' functionality.. Huh...

Maybe for the starter-spring.. to avoid stress to the prop-hub?

I’ve always found that safety hoop a little silly. What’s it supposed to stop from happening? Pretty easy to get your fingers in there still, from just about any angle plus they didn’t bother to install them on any other cox product.

You are right. Presently, I don't remember them installed on other Cox products, just a number of the Shrikes.

Yes roddie, it was there for a reason I believe. However, what the reason was, I cannot remember. I have been frantically searching the forum for the answer, but have yet to find it. If my memory serves me correct, it was discussed here a little while ago, and is where I got my information from.

Ok. In the following two threads, it has been called a 'Spring Catch', and a 'Starter Cam'. Either way, that is what I believe it is. Hope this helps answering your question.

Didn’t find a separate part number or name for the “spring catch” It is shown on the Shrike parts list but not given a part name or number:

The lime green Shrike machine 6731ad10

Maybe someone with a original Shrike owners manual might find a description.

Ok, make that 2 things I don’t understand!

I was’t following the first part of the thread, why use a starter cam when that spring was designed to be used without one, secondly I can see no way for that cam to engage the spring unless you pull it forward by hand so it catches, in which case it acts the same as hooking the spring onto the prop. Huh...

Thanks Ron. When I was looking at it, I was wondering the same thing. Maybe just something to keep the propeller from possibly hitting the spring? Or, was the original Shrike spring slightly different from the regular 'zero-drag' springs?

Ken says the "spring catch" is for the spring starter, here:

https://www.coxengineforum.com/t12810-shrikes

As for the "hoop" I always looked at it as a styling cue and a roll bar to protect the propeller and engine.

I’m just guessing, but I think the spring catch is just that. By using it you don’t have to stretch the spring out and over the prop blade, which over time and multiple uses stretches the spring and it doesn’t retract out of the way of the prop and cuts a groove in the backside of prop. By using the alum catch, the spring stays behind the prop and doesn’t cause any damage to the prop.
My 2nd guess is the “prop guard” is not to prevent fingers from touching the prop, but to prevent broken props when the Shrike rolls over with the engine running.

My first Shrike was a lime green one and it still has the green prop spinner and the metel catch for the starter spring.My first Shrike was set loose in a empty parking lot and the roll bar saved the prop most of the time when the car hit a pot hole or gravel causing the car to flip over.Sometimes the flip was strong enough that the roll bar would come free and then the prop would break.I am in the process of saving my first Shrike as it hit a curb at high speed and broke the upper body front between the front axle assb.and the canopy.Back in the day I fused the plastic together with a soldering iron and then used screws,nuts and metel strips to hold it together! I need to make a new front axle and 2 front rims on my lathe. I have the original manual some where,just not sure where it is right now!
