Default Modeltech Calypso

I have, I believe, a complete Calypso ARC that I've just starting working on.

There are a number of pieces that I cannot make any sense of.

Anybody got the instruction booklet that they would be willing to part with or copy? I'd be willing to pay any reasonable cost and would be very appreciative.

Phil, Check with PatternPilot as he is doing some work with the Calypso. He has a (new in the box) Modeltech Kit and It has the Instruction booklet with it. Scott has made a Fiberglass cowl and a Canopy for this airplane if you need one..

Phil,

I have a PDF copy of the manual but for some reason I can't locate it. It's probably on an external hard drive as I had to back up my system recently. I'll dig it up and post it when I can.

What parts are you having difficulty with? The ModelTech ARC has few parts so we can probably help without the manual.

I would love to know where the servos are to be located in the fuse for balance purposes. There are two dark ply pieces that may or not be for servo mounting that don't quite span the width of the fuse unless fairly far back in the wing opening. The firewall seems a bit thin and I was wondering if it would benefit from some tri stock behind it. The retract wells in the wing will cant the landing gear forward, so I'm assuming that combined with the reinforcement in the posterior fuse the plane is a tail dragger (and that the belly relief below the fuel tank is for a tuned pipe, not a forward trike gear). Are the aileron servo(s) just cut into the top of the wing, and how far forward of the trailing edge.
Obviously. if dosilia has the PDF that would take care of my problem. I have the stock canopy and cowl, but I'll contact PatternPilot about the fiberglass ones.
Phil

PS: Its seems there is a PatternPilot101 and a PatternPilot275 as well.

Phil,
The airplane is a tail dragger and yes the relief is a pipe tunnel. My airplane has two aileron servos mounted in the wings,
and It has a retract servo mounted in the center of the wing. PatternPilot does not have a number on his,
but you can contact him @ [email protected]

I have had Calypso's both ways aileron servos in the wing and a single servo in the center section using torque rods. I prefer the servos in the wings mainly because the fuse gets cramped for space. For balancing purposes I would put the rudder and the elevator servo's at the trailing edge of the wing in the fuse.
Cut the servo holes in the bottom of the wing not the top.

If you notice the box inside the canopy on the orange one that was done recess the rudder and elevator servo's

Phil,

everything that the two Dave's said above is also how I've done things. I used pull-pull on the rudder like Dave3 did on the orange one. The lines exit above the stab as can be seen in the photo. I centered my servo in the back of the wing saddle and mounted it flush with the canopy floor on two 1/8" ply rails. I also made a "house" for the servo protrusion it in the canopy area. I mounted the elevator servo on its side again on two 1/8" ply rails on to which a bolted a 1/8" lite ply plate which holds the servo. This allows me to unbolt the plate from the underside if needed and remove the servo off the plate. It is somewhat hard to access the servo screws if it were bolted to a permanent plate in the fuse otherwise. A standard size servo just fits in the fuse putting the output wheel on the fuse centerline. Having the servo side mounted results in linear action on the elevators to avoid any potential differential if the elevators are driven by either a forked pushrod or dual rods mated at the servo end. The dual rods are lighter than an arrow shaft if you use CF rods in plastic sleeves.

The throttle servo was mounted against the opposite side of the fuse where the elevator servo is mounted. Neither of these two servos protrudes into the canopy so only the rudder servo is "housed" in the rear portion of the cockpit. Receiver in front of that and battery in front of the Rx for balance.

There are two dark ply pieces that may or not be for servo mounting that don't quite span the width of the fuse unless fairly far back in the wing opening.
I don't recall for certain but they are likely two rails for mounting the rudder servo. They may also be ply plates for "backing" the FW on the fuse sides. Where they are located depends on the "depth" at which you glue in the FW. For a 2-stroke 60 it is glued flush with the front of the fuse (rear of the cowl). For a 4-stroke 90, you would inset the FW the necessary amount so the engine fits as they are longer than 2-strokes due to the carb being in the rear. Actually, I'm pretty sure that's what the ply plates you are referring to are for.

The firewall seems a bit thin and I was wondering if it would benefit from some tri stock behind it.
The FW should be 1/4" if memory serves. That thickness is fine but yes, do brace the FW with 3/8" tristock. Use the ply plates on the sides behind the FW and tristock on the bottom and top in the tank area. Gluing the tristock on tot he FW before you bond it to the fuse would likely be easier than doing it from the wing saddle afterward. You'll still need to pin the tristock from the outside so it has a tight joint.

The retract wells in the wing will cant the landing gear forward, so I'm assuming that combined with the reinforcement in the posterior fuse the plane is a tail dragger (and that the belly relief below the fuel tank is for a tuned pipe, not a forward trike gear).
The plane is indeed a tail dragger design. The location of the retracts in the wing would never allow the model to sit level if you were to install a nose gear. Their location is quite a bit further forward than the CG! I think the picture on the box (if you have it) shows the configuration of Hanno's original model with the retracts having plates on the struts to act as landing brakes.

Are the aileron servo(s) just cut into the top of the wing, and how far forward of the trailing edge.
I'd also suggest you use two servos for the ailerons. You want them on the underside (the model just looks nicer if they are not visible from the top) positioned so that the linkage will be close to a hinge point. Typically they are located about 1/3 of the way into the length of the aileron but can also be closer to the aileron root if they are short and only span half the wing. In terms of chord wise location, put them just aft of the thick point of the wing where the airfoil begins to taper to the TE. You want to find the ideal compromise between short linkage and keeping the cutouts in a thicker part of the wing so the wells don't bottom out the top side of the wing. That said, if you use standard size servos, they will likely require the full thickness of the foam core. Mini servos will leave some foam on the top side of the well. I believe the cores have a passage already cut into them for the servo leads and can be seen from the panel roots. Maybe the slots are just for the wing joiners (needed if a pipe is used and the wing bottom is tunneled out). If you don't use a pipe, you can likely use the slot for the rear brace to run your servo leads to the root into the fuse.

I have the stock canopy and cowl, but I'll contact PatternPilot about the fiberglass ones.
Phil
Scott has PET canopy (I believe) and glass cowl. I believe the cowl that comes with the MT ARC is not bad unlike that which came with the BlueBird Calypso kits (also distributed by world engines). The latter was made from a very thin layer of glass and polyester resin. They were usually dust by the time you received the kit.

I hope this helps, David

Phil,
Check your canopy, mine was junk from Model Tech. When I unwrapped it from the tissue it was warped and creased and blurry. It looked like they made it in the oven with their KungPao chicken. I bought one from Scott, it was beautiful. I also got one of Scott's cowls because mine was a little dry. Not bad but it would take a lot of filler to fill the weave.
You should have a couple odd shaped pieces of fiber glass plate in the kit. Those are for the pipe tunnel lining; one gets curved into the fues tunnel, the other gets bonded to the bottom of the wing after it's sanded to the proper depth.

I will just add that it's a damn good flying plane. Its fast yet slows nicely for landing, mine had a ST X61re and it moved with that engine.

My canopy was crap as well, I made one out of foam, glassed it and made a compartment for the battery in it.

Thanks guys, I appreciate all the help. The reason I asked about putting the aileron servos in the top of the wing was because the kit included torque rods that would have placed them on top, but within the fuse. Will work on getting the upgraded parts.

Phil, One word of caution, if you put the aileron servo in the center of the wing on the torque rods, there is not much room for the elevator and rudder servos. That was the reason Lil Dave's had the box built in the canopy where he could recess the servos.. In saying all of this, no matter what you have to do, the plane fly's very well !!! and is worth the trouble !

Guys, I have a NIB Calypso (Model Tech I believe), mine has the, excuse me, plastic or some sort fuselage, balsa covered foams wings etc. don't plan on starting it for awhile but all the manuals etc are there so if I can help with any info let me know. Also, if you know anything about the one I have the info is appreciated.

Yup!

That would be the Italian Aviomodelli version. Their wing tip layout, wing/stab planforms and cowl design is a little different from Hanno's model. There are also other differences including specs, moments and decalage I believe. There is a thread on RCU with such a model and a few build pictures I think.

The Model Tech is a balsa/foam ARC with skinned fuse foam deck and foam core surfaces. The Blue Bird is similar and both are a little more faithful to Hanno's design. The latter has poor quality wood for a built up fuse - mine was built from such a kit. There is no foam in the fuse as the deck is built from lite ply/balsa formers and 2 mm balsa skins. Quite nice once you iron out the gremlins and cut proper fuse sides and re-order the deck former layout. An additional former (lite ply) in the wing saddle section is also needed but not included. Otherwise, not bad exccept of course for the very very poor cowl. The canopy is not bad. It's yellow and quite solid compared to the clear of the Model Tech.

Thanks to Doug, I've got a backup MT ARC in its box as well with a set of e-tracts inside (which I'll rediscover in a decade no doubt) for an eventual electric version. Clean airframe and batteries inserted from a hatch in the top above the tank bay.

I did some homework a couple of years back. Hope it helps Mark.

Hi Scott,
Looks really nice! I hope it will be available as a kit? Foam wings? When do you think it will be available? I'll take one with an extra cowl.
Regards,
Will

You are correct David, I don't know why I thought it was Model Tech, but it is the Aviomodelli one. It has a white resin type of fuselage (I don't think it's ABS or the like, but it could be). Any how it still looks great, but it will have to wait... so many others to build ! Thanks again for the info David.

Will,

yes foam cores, wing and stab - ( customer to sheet) - foam turtle decks front & rear - (sheeted) canopy & cowl.. aileron stock... I'm thinking about framing the fuse ( jig built ) and leave the firewall loose so builder can adjust for motor. Drawing for the wing layout and some notes.
