It's the 72inch Tony Nijhuis Mosquito.
I built it a few years ago now and it turned out a bit heavy.
It is currently in bits on a shelf, after a nasty tipstall incident.
According to his website, the Tony Nijhuis 72in Mosquito weighs 14lbs and has a wing loading of 40oz/squ ft.
Tapered wings and a high wing loading is not a combination made in heaven. ☠️ -
David if you scroll down to Pete H’s 2nd post (on page 3 of the La7 Warbird Replica thread). You will find some photos of ‘cutting the ailerons free’. HERE.
Regarding your comment about ‘no stringers or internal structure’, a veneered foam cored structure is stressed skin or monocoque so does not need any.

My apologies for not replying....
That video was awesome! What a great flyer.
The foam wings are only the outboard wings from the booms to the tips.
One issue I have is how to build them up. They are already veneered with no cuts for flap and ailerons.
No stringers or internal structure. I'll have to work out how I will tackle them.
Maybe not use them at all and go for the full build..?
David, veneered foam core wings are sometimes supplied ‘intact’ in that you are required to mark out and then cut with a sharp scalpel the ailerons and flaps (when fitted). You then have to trim off some more material in order to face the cut edges with strips of balsa. These then are slotted to take the hinges. You will also have to bevel the ailerons to facilitate their movement up and down.

Alright you lot......If I cant have my Japanese plane I'd love to see an Arado Blitz Ar234 with twin 50mm EDF's
A hand launch and belly lander would be fine.
Good one Keith, make a change from the ME262 or over modelled A10 Warthog. Thinks; the plexiglas in the front might be a tad vulnerable in a less than perfect landing but it could always be painted balsa. Go on, build one and have the plan published in RCM&E!

Even so , I am slightly baffled about the reluctance to try a twin .
More expense ( two motors/ESCs, wiring and bigger batteries) may put many people off a twin?
Traditionally IC twins need to be bigger because of the weight, to keep the wing loading sensible. Bigger models take longer to build and a ‘scale’ mossy with its oval fuselage cross section will certainly be more challenging to build, which puts off people who just struggle to build a fuselage that is straight ( I empathise 🤣).HOWEVER, with Richard’s WR USP of simple ‘scalish’ build lines, foam wings and E-power using a couple of ubiquitous 2200mAh LiPos, it could be very appealing indeed ❤️.
60in span could be the sweet spot in terms of span if that wasn’t too big for a couple of 2200mAh batteries?

Or maybe a dolly and belly option.
I will go for that option.

Presumably ply, not lite-ply? Could the retract mounting plate be made thicker- more meat for the screws to bite into ( yum!)
Alternatively use bolts poking upwards (wire lock buried heads so they don’t rotate).
What I am driving at is, I am fretting about the gear being ripped out after an ‘arrival’ onto none too short grass.Maybe I should just keep taking the Valium or get another hobby. 😉

Hi David, it is something that I to wanted to build.electric was /is my choice. I have the plans as well. I just cant make that last leap. It looks like a big project, it worries me that it will drag on for some while. Please keep this thread going and keep in touch. Yes please keep in touch!!!!! Where did you get the foam cores?.
Bas
Foam core wings are easy and quite satisfying to build too. Polystyrene foam is cheap and plentiful. Reinforced with carbon fibre strips and covered with brown paper with PVA, are ridged and quite light too.
As an alternative, I can vouch for Bill kits, their wings are well made and reasonably priced. Saves a lot of time too. -
Richard is in the ‘business’ of selling kits and probably the reason why there aren’t many kits of the Zero or Nakajima is because there isn’t a lot of demand for them? As for the Betty Bomber Keith I think you could be on your own with that one.
We probably all have our own list of ‘interesting’ (kwerky) or sometimes ugly planes to model but they would not be very successful as kits.Personally I think a kit of the DH Hornet would be great in preference to a Mosquito but I don’t think there would be many other takers.

Yes, BEB was a really great contributer and moderator on the forum. Much missed.

Beautiful work, but ... Wot, no pilot! 😮

Either would be good for me Richard.

Geoff, after covering with brown paper I just seal with another coat of slightly diluted PVA before painting. I apply PVA to both sides otherwise the tailplane or fin may warp as it dries. You end up with a smooth satin finish which takes paint well.

Are you using differential aileron John. I just wondered if adverse yaw might be causing issues with rolls.
Perhaps a larger fin area might help too? -
I am sure they will all confirm in due course Richard but you could always PM them individually, as some people are not forum junkies (like me) and only visit the site infrequently. I doubt anyone would think you are hasseling them but just trying to get a firmer ideas of numbers (which could influence the price). 😊

Mossie as first choice.
Second choice:- Sea Fury developed from Tempest kit.Third choice, Grumman Wild Cat but dolly take off/belly land as the full size landing gear is way too complicated to model.
Not interested in a P47!

Personally, I like the challenge of building so would welcome something more complex.
Admittedly, I do have a few builds under my belt but with each build I always try something new in order to advance my skill set. Currently I am building the Mustang and will be trying out the ‘Brown Paper’ method of covering for the first time and also, I will be adding a bit more weathering than I have done in the past.
I have not tried planking before so would welcome that in a kit.
I would love a Mossie but would be equally tempted with a Razorback Jug.
I fly electric and ‘full fat’ models always appeal.
Size wise, I would be happy going large - anything up to 80inch span.
The problem with ‘going large (80in wingspan)’ is the cost of a kit goes up exponentially with size. Less demand for bigger kits for that reason.
I think Richard has hit the sweet spot regarding size.
I built a Blackburn Firebrand from B & Q polystyrene reinforced with carbon strips and covered in brown paper. Super cheap and if building bigger models is your thing and quite quick too. My Firebrand was only 52in span but my next build using this technique will be bigger!

I live in the Dorset so I can’t help you unfortunately. What I would say is so much of public open spaces have bye-laws affecting them these days. Also National Trust, Forrestry Commission land and many national parks are not model aircraft friendly sadly. Your best bet is to politely ask a local farmer for permission…but good luck with that!
Not all clubs are the same so I suggest you visit two or three. Most are kindred spirits so generally want to make you feel welcome. It is human nature to be wary of newcomers to some degree however. Flying sites are hard to come by and easily lost if people get on the wrong side of the landowner. The club I recently joined is very friendly and any rules are just common sense.Good luck in your quest to find somewhere to fly and welcome to the forum by the way.

Very sad news indeed. Good luck for the future Jon and thank you for all the sage advice you have imparted to the forum over the years.

I don’t have any 800mAh LiPos but plenty of 1350mAh batteries. I am concerned about the wing loading with the larger heavier battery (130g) as it might spoil the low speed handling. Perhaps a 10% or 15% plan enlargement might be the answer?

How easy would this kit be to convert to a Sea Fury??? Just asking..... I love the look of the FW190 but the Tempest isnt a favourite of mine and I wonder if a bit of fettling the front end would make a good Fury?

The way to build a Fury is to persuade Richard to make it his next kit, after the Tempests are all sold and the (balsa) dust has settled.
Put me down for one by the way (preferably bigger😊)

Thanks for the explanation Shawn, makes a bit more sense (I think? 🤔)

So sorry to hear this Matty. Get well soon.

So sad to hear this Iris, my condolences. Chris’s contributions to the forum will be missed.
The Big Question ?
in Warbird kits

Lightly loaded aeroplanes just fly better, whether that is a model or full sized B747. They will fly on less power, land and take off at lower speeds. Needlessly adding more materials to make them ever stronger is counter productive because of the weight gain.
One complication I am keen on however are flaps, not just for low speed arrivals but to stop the long float in ground-effect before touchdown. Some years ago I remember watching a friend’s Mossie come creaming in over the threshold at low level before floating the length of the strip. Finally he landed in the ‘rough’ and ignominiously ending up inverted. That is when you do need a tough model! Of course he was coming in like a train because of the fear of the dreaded ‘tip-stall’. (I would have done the same)
Flaps? A good servo is all you need in terms of added weight, a good trade off I feel.
