Title: VMC Sopwith Triplane.
Post by: Ex Member on August 28, 2017, 03:40:25 PM
After being hounded (excuse the pun!) by VMC for a while I have got round to doing a Sopwith Triplane for the range.

The relatively narrow chord of the wings meant I had to make this one an 18" span like the Tiger Moth, and unlike the SE5a, and Camel which are 16" span.

The picture shows my rough hand cut prototype airframe, I do this normally to quickly check for any gross errors and problems, try out the method for the wing alignment jigs and trial the first stab at the paper parts.

The tail surfaces will be built up, the sheet parts are just the basic outlines, and the observant of you might notice the missing wings  ::) ;D ;D

While recuperating from back issues I am doing my reading, and am just finishing up my 3rd reading of Sagittarius Rising by Cecil Lewis. He began as a fledgling flying the Maurice Longhorn, then the Shorthorn, with very little flying time graduated to the Fe2b, then the Morane parasol. When he started flying the scouts it was the SE-5, the Camel, but the plane he said was the easiest most flyable well balanced was the Sopwith Triplane. It has been on my bucket list for a long time, and I do get a kick out of flying Thee Old Mans tripe now and then. It is a most stable and well mannered model I have ever flown. But I do want to build my own soon. It's one of those planes that just looks like a model airplane. It looks like the stars are lining up for a Tripehound build!

The prototype is nearly done.  The wing alignment jigs seemed to work of again with three wings.

I just need to detail and fit the gun and cover a few bare balsa areas with tissue, before giving this one a heave.  I forgot to weight it but I think that it is around 40g sans rubber an nose weight.  I think that there is a plenty of wing area to hold it all up.

The cowl areas are paper but I've put lines on the patterns to simulate the formers on the real thing.  By going over the lines on the reverse side with a ball point pen on a soft surface (eg a piece of scrap balsa) they come through pretty well.

Cheers Pete,

Yes, it's mine, Hadi rang me to ask to see if they could use it, as it is my prototype.  I normally keep the first flying one, but i finished it reasonably well and I didn't ding it during its test flights so I let them use it for trade shows...

Modler If you go the the website, they have them for sale:

Other than that I think they are trying to get channels into shops in the states, but I'm not sure what is happening with that...

Post by: Ex Member on September 26, 2017, 05:01:02 AM
Cheers guys,

I think the next one might be the Bird dog, I found a decent 3 view.  My only quandary with it is how much to simplify it.  Many models of it (including the Guillows one) flat bottom the fuselage and it has fairly slab sides.  On the basis that high wingers make better novice models flying wise, a simplified construction would also seem in order, so probably middle ground, with slab sides but with a simplified curve below with a couple of stringers to define it.

I threw the tripe on to the bed last light, it is very floaty, there is no additional nose weight ATM but it didn't just pitch up so I believe it won't need a massive amount like the Camel, that very rearward bottom wing must be helping with that.  The forward peg position won't put the weight at the back either so it looks quite promising.

Jon, I reckon' this one would be good for you, more room for one of your CO2 motors and the tank etc... ;D

Post by: Ex Member on October 29, 2017, 11:54:20 AM
Well this flew pretty well much of the board which is pleasing.  As is my usual M.O. I put in a fairly tame and short motor to begin with.  This is a flight caught by Pete F. on my phone, before I added a smidge more nose weight which helped reduce the stall-iness a bit.  I think that it is turning on torque a little too, but I was happy enough to see that it has no nasty tendencies and nothing fundamentally wrong is going on...

Opening out the turn and a more aggressive motor should see a better duration.  I will save that for another day...  ;D

I agree: 'presence' is just the word! Even better in the flesh and it somehow seemed rather bigger than its 18" span. If it's in the shops anytime soon it will leapfrog the Camel in my VMC 'must build one' list.

Looks super Bill, really good.

A notice For other builders... Both the Triplane and Camel schemes that I chose do not have fuselage roundels, so it leaves those that want to do alternative schemes a little short.  Bill suggested that we provide them on the "additional resources" page on the website.  To this end Bill gave me the suggested sizes and I have drawn up an additional sheet which is free to download. The VMC boys are at a trade show next week, so I suspect that it will be the week after before it appears.

I made these neat little wheel covers for my VMC Tripe last night.  The rear side is just 5 thou styrene cut from sheet using a circle cutter and the coned side is vac formed from the same material.  After they are painted you just position them with a bit of Tamiya tape and then wick in a bead of thinned RC56 canopy glue.  These photos don't show it very well but I managed to sand a slight convexity into the mould near the centre where the canvas covering goes over the hub.

If anyone is actively building a VMC Tripe and would like a set of these as an alternative to the usual paper cone lark just send me a PM and I'll be happy to send you a set gratis.

Post by: ZK-AUD on May 08, 2018, 01:59:29 PM
You may recall that I also made a vac formed cowling front that works better if you're covering the nose section in wood rather than paper (as provided on the plan).  Also happy to flick you one of those

Thanks guys.  If you look at the picture of the mould you may be able to tell that it's actually 2 parts.  The crankcase and the front plate.  It was roughed out on my table sander then carved and sanded by hand.  No lathe was harmed in the production of this part!!  By the way it really is no bother if anyone does want one of these to try so don't be shy.

No the bolt heads are styrene mouldings that come in different sizes on a sheet of plastic.   You get bolts on one side of the sheet and nuts on the other.  Slice 'em off and stick 'em on.  You'll find these anywhere railway modelers and plastic scratch builders are to be found

Post by: ZK-AUD on May 28, 2018, 01:54:50 PM
As promised here is how I will regulate the thrustline. Very simple - just a thin brass plate with 2 slots allowing a latitude of movement up and down and side to side.  The back of the nose plug is reinforced with 1mm ply and there is a small spruce insert for the screws to bed into.  The Peck bearing at the front is glued with RC 56 which just holds it in place but allows it to remain flexible.  As I have previously opined this is a much better sort of thing to spend your nose weight budget on than a heavy prop!

Title: Re: VMC Sopwith Triplane.
Post by: ZK-AUD on June 02, 2018, 05:03:02 AM
Here/s the freewheel I've gone with for this model.  It's a refinement of my earlier scheme which calls for the cross tube to be square lashed with fuse wire.  Here the cross tube is drilled through into a larger tube and the whole is soldered on the front of the shaft.  I slip a piece of gasket paper onto the shaft to protect the plastic prop during soldering and rip it out afterwards.  The washer immediately behind the prop is soldered to the shaft and takes all the load.  The prop itself is floating and this gives a very reliable freewheel - 100% guaranteed!  

I have used a jasco thrust bearing which again is a much better use of the nose weight budget than a heavy prop


Title: Re: VMC Sopwith Triplane.
Post by: billdennis747 on June 02, 2018, 05:32:50 AM
That's a very neat solution Mike. It saves binding stuff to the prop and reduces the scope for flesh wounds with a Garami. I'm guessing it's best kept for small models as a simple soldered joint to the shaft might fail with a big motor?


Title: Re: VMC Sopwith Triplane.
Post by: ZK-AUD on June 02, 2018, 05:45:47 AM
You'd be forgiven for thinking that but even though the torque on the joint is high the length of the joint compensates for this.  Good soldering technique is important.  A hot iron applied to the work and when the work is hot enough to melt the solder you get a good sweated joint.  I have successfully used this freewheel with up to 4 strands of 3/16


Title: Re: VMC Sopwith Triplane.
Post by: ZK-AUD on June 02, 2018, 04:07:26 PM
Not wishing to appear needy at all but just wondering: I've posted a lot of examples of these sort of freewheelers on various threads along with the soldered plate taking the load.  These ideas are the fruit of my endeavours to engineer out the usual suspects that make life more difficult than it has to be.  I'm really interested to know whether anyone else out there has had a go these methods and how it went

When I finally get back to building, I plan to try your freewheels - my scaled up Fury will hopefully need one. I used one of your freewheel devices on the Nieuport Bebe, but its best flight so far landed gently on the runway with turns on. When I fly her with a meaningful number of turns, I'll let you now how the freewheel fairs!

Very mindful craftsmanship on this build Mike. You have unlocked the vault of how to run that flying wire through the middle wing without it being a hole-tearer! I apologize if this is a redundant question but what is the weight at this point?


Title: Re: VMC Sopwith Triplane.
Post by: ZK-AUD on June 05, 2018, 01:50:40 PM
Many thanks for the nice comments gents. 

Jack, it's glided or glid.  Very slow and rock steady with a straight stall and no wing drop.  I was a little concerned by the amount of incidence on the top wing as designed so I reduced it slightly by the double expedient of washing out the top wings a little,  which also gives me the lovely straight stall.  I plan to try her on 4 strands of 3/32 to start with.  This would have been over our long weekend just gone,  but we ended up with torrential rain and howling winds.

Crabby the final weight ready to go is 40g ballasted which is about 5g heavier than I expected but I did go to town a bit with detail.  Even so its pretty acceptable - lots of wing to carry it.

It's lovely and that seems like a very low weight for such a detailed model; c.f. my "no detail whatsoever" Camel which came in at that weight or thereabouts trimmed.

I thought people might be interested in this short video of my VMC Tripe flying in Australia a couple of weeks back.  It needed a little more noseweight which cured the slight stall in the next flight.  I got an ROG off the model box in the foreground but unfortunately the wife missed the beginning of the flight.  Power is 4 strands of 5/32 which it needs to cope with the drag and all the noseweight!

I suspected that the design might have a little too much incidence and moderated it with 1/16 washout on all wings - so this has reduced average angle of attack and given it a very stable stall as you can see in the video.

I have an evil plan to build a non-kit version of this model using all the tricks to keep the weight right down and pump up the duration using thinner rubber. 

A surprisingly viable model and a real credit to our Andrew.
