Running up my Ebay AND Travis' Conquest .15's !

That's mad RPM< as Kris said that's very high for a conquest, are you sure it's stock and not modded?

Did it really sound like 20000 or did the tach pick up a reflection or something?

I haven't run mine for quite some time but it should do around 20000 on a 7x4 and about 15000rpm on an 8x4 (from memory).

The CL version with the large ventury needs to run with tank pressure, there should be a nipple on the backplate for that.

Thanks Kris! OK...I thought as much. It SOUNDED fast, but I'm easily impressed. Figure the tach WAS getting a reflection, and I'll have to give it another go.

I appreciate the tip on pressurizing the fuel. The engine doesn't have a pressure tap, so I may have to see if I can get one from MECOA.

Yeah...it's what I get for being too quick on posting these things! Figure to do a re-run when I'm not pushed for time !

There ya are Kim, wondering where you went. Seems you finally found your Conquest. I am thinking about one for my "Perky"

It would be a good fit. Looks like a screamer.

Hey Ron!
Yep...still messing around. Been flying my Lazy Bee around with a P.A.W. .06 Diesel on the front. A little small for the Bee, but it DOES fly...sort of !
Looks like I've got some work cut out for me to make this Conquest runnable !!!

[quote="Kim"]...Also had the glowhead try to quit on me, but was able to prod it back to life with a straight pin. Figure that I need to lay in a supply of these glowheads if I can find them!

There's a couple on eBay right now.

Appreciate it Steve...looks like I've got a line on a carbed version!

OK, I drilled out the backplate pressure fitting with a number drill that matched the inside diameter of the pilot hole on the stem. IT FEEDS NOW !!!

I was running it on 10% GPB with a M.A. 8-4 square-tip prop, and getting (I'm pretty sure this is NOT an illusion) a strong mid-17 reading...which STILL made me act like I was trying to pet a cobra when adjusting it.

The needle, however, is VERY sensitive with a quarter-turn being the difference between it running peaked and slobbering out...with what seemed like a lot of fuel coming out from front bearing. On pulling it from the stand, I noticed that the venturi has a slight looseness, not flopping around, but just a tiny movement when pressed. I figure this might be letting it suck air around the O-ring, and intend to check it out this morning.

Also, I noticed that there are two venturi sizes offered for this engine. Would one be better suited for CL as opposed to R/C (I'm talking pure Sport Flying here), AND allow me NOT to use case pressure? I can't find the site at the moment to list the size numbers.

On a recent Secret Skunk Works Mission to the Home Town of Popeye, I relieved Travis of his cherished carburated Cox Conquest. Naturally carrying some suspicion in dealings with ANYONE riding one of them big nasty motorcycles, I can convey that, yesterday, I was able to test run this .15, and I can confidently report Travis as an honorable dude !!!!

It turned in the mid-13's on 10% GPB, with an M.A. 8-4. I was about to get blasted by Hurricane Issac's leftovers, and forgot to check the Conquest's low-end, but will do that shortly.

Kim, last weekend my son and I were involved in a racing event . We generally race Foxberg planes and I run the Fox to death. I lost the plane last year to a failed control horn which resulted in the crank bending and the case shattering. I was a bit hot about that. I still have a good piston liner fit however. I will get another case. This year we raced PDQ Flying clowns which Brodak re kitted. I fly the PDQ version which I prefer. The OS LA.15 is my choice of engine and I run 40% nitro with a clipped down APC 7x6. I held 3rd all day until the end in which we got bumped to 5th and I was running rich. We got beat out by the COX Conquest.15. It was hauling the mail. I believe he may have been running some seriously high nitro. We can't exceed 140 laps in 6 minutes. I was getting 129 laps with 3 pitstops. Old hat technology still rules. Ken

The OS .15 CVA would be a better comparison/representation of modern engines I think. The LA series are rather timid and only have two transfer channels etc.

Man that stuff sounds like fun. I hope I can make it out to the Brodak Party next year. Just seems like something always pops up, and draws me always from making the run.

One of my many "Ought to Do" projects is finishing my Goldberg Shoestring and bolting my cut-down Ebay Fox to it. Purely for fun, but it ought to be interesting anyway.

"We can't exceed 140 laps in 6 minutes. I was getting 129 laps with 3 pitstops. Old hat technology still rules"...What length lines are you running in this event? 60' ?

Kim, were using 52" lines. In regards to the OS CVA engine, they were used and they get DQ's for going to fast. This event is not for the fastest but to keep within certain parameters. Clown racing pretty much got way out of control and we race similar to Brodak rules. The difference being, Brodak is all LA .15's or Brodak 15's 1 oz. tank and 52' lines with contest supplied fuel. Our rules allow ANY engine up to 19.9 any fuel but you can't exceed the lap amounts within the certain time. The CVA engine will do that unless you choke the intake down. Bordak also flies with a minimum of 3 in the circle while we use 2. Chaos comes quickly when your flying too many in the circle. I've done as many as 5 just for fun but it gets ridiculous. Ken

How did I miss this? Glad you got it running. Did you end up changing the cylinder/piston?

It just cranked up right out of the bag! Funny thing...I've been running all these unbridled, carb-less engines so much, that I forgot to check it's throttle response! We'll fix that when I get a chance !

Yep, looks like a healthy pup !!!

Well, I MIGHT have put a new glowplug in it....
