Default Protech Tojeiro 140 Build

FWIW - just had to have a pattern plane because nothing flies like one... so... here I found this under $460 DELIVERED "pattern ARF" that is touted as an F3A capable airframe. We shall see.... but anyway - it arrived today, and so far, I am quite impressed. The build quality and covering is just unreal. Many of you know, I've done some "pretty rough" PARFS in my day, and I had no idea what to expect. But this one is STRAIGHT and CLEAN. Excellent, and REAL Oracover(Ultracote) covering that is actually STUCK DOWN.

Fully sheeted fuse... all wood. Fully sheeted foam stabs/wings..... no belly pan, just a nose cowl. Roomy insides, and everything is laser cut.

I assembled it tonight, dry, to check everything. Stab fit to fuse is best I've had. Same with the wing. Incidences the same on all surfaces, both sides.... obviously this is well-jigged to assemble so accurately.

Some pics of the dry fit, and the beautiful interior.... I think this will be a fun build.

BTW - MVVS 1.60 Gasser, Mueller header, and we don't know what pipe yet.....

Hey Bob, looking good. Looks alot like mine. heehee Mine went together nice, no surprises. Ran into a flu bug today, so not much more work on it tonight. Are you going to use included hinges or go with CA ones? I'm going to use OS 1.60 with a hyde mount. Not sure of header or pipe yet. May pull Aeroslave pipe off Arresti and see if will fit.

Thanks for build thread Bob.

Precut hinge slots are too thick for CA, and the stock ones look pretty good. Pacer "Hinge Glue" makes easy work of these; I have several bigger ones that are holding up very well...

OS is good choice - it will be under 11, --- but --- tunnel is not deep enough to accomodate the Aeroslave (or my Mac's clone) without cutting out the bottom, making an exposed tunnel. That's not a bad thing/good thing, just depends on what a person wants. I would like to be able to have the whole pipe internal, with only the exit air cutout.

But you are correct - this is a good looker....

Here's the pipe... a newer Petrol pipe specifically for the 26cc gassers... from ES Composites, http://www.escomposites.com/petrol.htm and it will FIT !!

Aileron links completed.... using 8231's and Sullivan 566 long control takeoff links. Used my standard "reversed blind nut" mounting for load distribution. As shown, gives 18* travel, which is about my normal for these birds...

Stab pic is just to show - this are pretty large... 32" span!

Hey Bob, I noticed you said that your fuse was tall, and the body was wide. Can you tell me how wide it is at the tube, and also how tall the fuse is with canopy.

Thanks

Flyinrazrback - see post #1
rgreen24 - the fuse is constant taper, much like a laser. At firewall it is 6", tube is 14" aft of that, is 5" wide there. Rudder post is 62" from firewall, it's .80 wide. Fuse is 13.5" at highest point of canopy, which is 19" aft of firewall.

Don't know if that matches any else's definition of "wide body", but it's larger than the Arresti, I think. bogey64 ????

Compared to the Arresti, canopy measurement approximately 1" taller, width at firewall is about 1" wider.

Do you think a Electric Retro fit would work in this airframe?

Hi Bob,

Do you think the Aeroslave pipe for OS160 will fit in the tunnel without cutting it open?

Thank you,

Kevin

How are you?

Really nice bird, let keep us informed about building and especially flying

See you soon!

elan120 - ABSOLUTELY will ***NOT*** fit without major surgery/opening of the bottom. That is the reason I'm using the new ESC "skinny" Petrol 26cc GT pipe....

I'll let everyone know how that fits/works/runs, right now this WHOLE FREAKIN' THING is a total experiment..... BTW - stab is located 1.25" ----B E L O W---- thrustline ( ??????? )

dentdoc - I will post the raw weights spreadsheet.... for right now, go to www.rcaerobats.net "Newest Updates", toward the bottom is a link to Tojeiro140_Wts

I am totally NOT the person to speculate on electric power ...... but based on what I've read this dog won't hunt on e-power.

11.5 lbs? Is that right? I was afraid of that based on what I'd heard from Europe a while back. I'm sure you can bring it in under weight with a few tweaks, it's just a shame it's not lighter. A HUGE 2 meter plane CAN be built in the mid to low 9s if wanted but it takes a lot of attention to do so. Not sure mass production would work at those weights, but they seem to have the Icepoint figured out as far as weight. But it's not really that big, and neither is (was) the Focus.

The low stab is old school tech. The Typhoon 2000 was like that. It had very little mixing on knife edge, didn't pull much in a down line, but took an act of god to snap and spin because of over 1200 squares of wing and the wierd angles it needed to fly right. It also used a full degree of positive in the wing and some wild thrust angles. As much as 5 degrees of right to make it track right vertically. I changed a lot when I did the "Tempest" version, and it was much better in a lot of respects, but it was really a bandaid on a gunshot wound to the head. The patterns changed, and the planes had to follow.

The Tojiero was actually designed a few years ago but was never imported to the US. I'm really really curious as to how this project turns out, and I'm sure Bob will give us the whole picture. More than what it weighs, I'm interested in how it flies.

And no, I don't think it'd make weight with electric unless you used a foamie battery

MHester - I agree on ALL points, and am approaching this somewhat tentatively now, having looked at the angles, dangles, and decalage. BUT - one doesn't know if not tried - so..... it's "what I do".....

I also must RECANT my statement about the Aeroslave CF Pipe after receiving my Mac's 1092 Clone - it is exactly at 1.75" diameter, which I *believe* is the same as the Aeroslave. The Mac's clone fits just dandy, and leaves a good enough air gap around.

Regarding the handling..... ya'll will know IMMEDIATELY when I test fly this thing...... if it ain't a GREAT snapping/spinning airplane..... BYE BYE!!!! Ain't gonna try to make a pig's ear into a silk purse, by any stretch of the imagination.

But - so far - I sure like the build and assembly quality. It is DAMN good.............

If I remember right, the Tojeiro was designed by Laser Models a few years back.
It may not be the most modern pattern design around...but it sure looks good.
The petrol engine setup may cost you a few oz in extra weight, but you can train all day for the cost of a Big Mac and a Coke

Looking forward to the flight report

Hey Mike I think that Bob is using a gas engine. I think if you used a four stroke or a 2 stroke the weight would not be an issue. just my .02 cents.

I saw that, but if you take away the extra weight, it's still pushing 11 as is. No issues with it being legal, I was just hoping it would be lighter.

But if it flies great at 10 lbs 15 ounces, who cares?

Hell, Mike, you know me - if it flies well at 13 pounds, I'll keep it..... that weight thing just ain't a problem (as anyone who KNOWS me can attest to) on my radar.

Mine with the MVVS gasser, and the ES pipe will be right at 11 lb 9 oz..... so take out 6 for ignition, and 5 for battery and switch, it's "legal"....

But who am I to quibble over such trivialities?????

Also don't care if it's an OLD design.... hell, **** I **** am an old design, and I can still work pretty good (sometimes, depends on who you ask)

Anyway - we press on!!!!! Hoping that it is NOT a 'POS' that won't snap and spin.

Any plane can be made to do anything you want....some just take more work than others.

I don't think this one is far off, I hope that gasser has enough pull for the verticals at that weight. After all, if it ain't the nats, you'll never see a scale.

Even the T2K could snap and spin, it just took some wind up and some lead on getting it to stop. Spin breaks were the hardest just because of the wing area....if it wasn't 11 lbs, it really didn't want to stall without some help.

The Tojiero has a better looking wing and I don't think that'll be an issue. I don't know if that's the same wing it started life with years ago or not.

Anyway, as I said, I haven't ever seen one of these fly so I'm burning with curiousity. I love playing with designs and this one is different enough to be interesting. looking at an Arresti you'd never think it would fly as well as it does; I flew Jock's in Aruba and was very impressed. This one LOOKS better from that standpoint.

Good job reporting on this thing, it's good to have you back over here exploring pattern options [8D] And I for one am anxiously awaiting a good flight report.
