Just need a flight report now!

I have too much throw in elevators and ailerons and will tone that down tomorrow. And will start to check for the essoteric flying envelope that pattern demands
The engine has more than enough beans on the Mintor 38cc pipe and 19x10 XOAR woodie. I didn't push it of course but it was terrific stuff to see this really cheap engine behave that way. Heck I think I paid around 265$ for the PTE36R. Not equal to the OS33GT but it doesn't have to be on a light plane likethis one
Landings were feather light. The gear mods are keepers. The light gear are much more flexible yet strong enough, at least until I realy dork a landing or take off. That damped flex, like shock absorbers, causes the plane to just glue itself to the ground when it touches. A positive result all around and another good experiment
Time to move back to my main project, completing the Delta.

RE: Let's gasify a Vanquish
Thanks Arch,
It's going to be a good plane. Very capable. Just need to get the engine broken in and wring the plane out . So no time to waste....off to flying it
Joe, hopefully Augie can video it today. We'll see

RE: Let's gasify a Vanquish
Hi Matt,
Just checking to see I'm reading this right...0.2 positive on stab and 0.3 positive on the wing is 0.1 positive relative from the wing to the stab? That's surprising as it's quite different from what others have on theirs in the electric version, and I'm just curious why that might be? Appreciate your thoughts on this... Cheers.

Hello Matt
Which quality oil and % volume do you put in the fuel ?

Hello Matt

Claude
I've used the same mixture since I re-started flying petrol, just about 3 years ago. Early on I used regular 87 Octane auotomobile gasoline and chainsaw/weedwacker oil at 30:1. Oil was purchased at the local Home Depot. I did that for a couple gallons before switching. Hated the stench of autogas so I looked for an alternative petrol
I met up with long time noted modeler Jersey JimMartin 3 years ago and on his recommendation I switched the oil to BelRay MC-1 motorcycle racing synthetic. Jim is a long time motorcycle racing enthusiast and expert engine mechanic and in fact his son was a racing Champion years ago. Jim knows his engines and better yet, knows the oils that work best....MC-1 works absolutely great.
The DLE55's (2), SAP 30's (2), ZDZ 40, Mintor 38, OS33GT's (2), now the PTE 36R, and the BME58xtreme, have all used the same mixture on Jim's suggestions-Avgas 100LL and MC-1 at 50:1 ratio. The oil comes in 12.8 oz bottles which produce the desired 50:1 mix when mixed with 5 gallons petrol. It's likely that in Europe the packaging is different since you guys are dealing with liters, thereforemaking ratios easy .
EDIT....forgot to mention that I use the same fuel for break in as well as after break in. Nobody has shown tangible data that one type of mix is better at break in over another. And since my engines simply run and run, there's nopoint in changing this process...

Don't really know what others have done, sorry. I don't follow anyone's set-ups since I can't be certain of how they make their measurements. I make mine on agranite top with a height gauge and make my measurements in 0.001" increments. It's way overkill but in the end I know whatIhave, with precision and accuracy.
Electric, glow, gas, rubber bands,doesn't matter one bit. My Vanquish has zero down/up thrust, 2 degrees right and could use a bit more, +0.3 on wing (no offset between left and right panels) and +0.2 approximately on the stab. I say approximately because it was a quick reset of the adjusters at the field on the first day out. It's approximately15 thousandths positive at the stab LE (about 1/64") but I have not rechecked with the height gauge. One should understand that 0.015" on the LE is actually 0.03" over the root span of the stab which I think is 11". You may want to do the trig........
Inverted flight cleaned up nicely after the stab adjustment. With proper amount of toprudder there is hardly a hint of movement in knife edge. When lots of rudder was applied there was a slight tuck to belly but then again I was well into a knife edge loop

Hi Matt,
Is the PTE, or even the OS, fairly user friendly for a first time gasser? Any kind of comparison to an OS 2-stroke glow? Just curious for now...

In the case of the OS33, it puts out similar tork to the YS170-175 throughout the throttle curve. Top end favors the OS but we don't really care about that in pattern; they all have more than enough top end power and we just don't fly there. The PTE doesn't compare after 2 hours of operation, eventho it has the edge on cubes. To be fair I am still learning this powerplant and may not have it propped quite right yet.
Vibes to the airframe are about the same as any other well behaved 2 stroke and far less than the 170-175 4 strokes. In fact, I am quite pleased with how this super lightbalsa model is shaking at idle. It shakes far less than my glass/foam Aesthesis. But that's not saying much actually since the glass fuse I used was a Brio fuse. It wasn't that well made.....
That's about it on the important points.....

RE: Let's gasify a Vanquish
You're both welcome!
Claude, I don't know what kind of load the DLE30 can haul....Everything I've read says to start with something like an 18x8 and break it in first. That's probably a good place to start.
On a canister I would expect the engine to be able to haul a 19x8, maybe a 19x10. You're going to have to experiment....
BTW- I decided to get a DLE35RA and see for myself if that engine is equal to the OS.I believe the rear exhaust header I have on the PTE will be a drop in fit. I will probably fit it into the Vanquish. But that's likely one of next year's projects. Winter is upon us and we actually had snow today...just a dusting but maybe a portend of things to come??

Hello I am Matt Griffitt
I am a custom Motorcycle builder and ama Pattern flyer . I should be able to build a alum header pipe for less than 20 bucks and a thin walled expansion chamber cheap as well. check out my work at KMF-Industy.com

RE: Let's gasify a Vanquish
I was trying to figure out what my next (non-pattern) plane would be and haven't found it yet, but now I am thinking it will be about the gas experience and am pretty psyched! Will be after I get the Integral up and running of course Thanks again Matt!

RE: Let's gasify a Vanquish
A couple shots of the revised landing gear. 158 grams RTF, painted. Compares pretty wellto any other gear I believe. I have this molded so if anyone is interested in shedding some weight, I am making them available on a limited basis. PM me

RE: Let's gasify a Vanquish
Claude, BTW, where did you get that back-to-center header? It looks very compact and will work fine with the OS33GT. Same exhaust dimensions

I used to get my headers (as well as wing adjusters, control horns, etc) from them for the OS 160's. The quality is very good and I think the performance of the 160 headers was better than the Hatori.

I couldn't see if the header alone was available. Do you know if it is?
BTW- we finally put a video together of the gassified Vanquish, http://youtu.be/NvzPkbHACzM
The Mintor aluminum pipe is abit louder than the ESComposites but it appears to work well enoug in developing fair amount of HP. In the video I gave credit to the wrong enginemanufacturer. No the engine is a PTE 36R not an SPE. Apologies for any confusion
