Build Log
de Havilland Mosquito

Hi Guys, after much discussion on another thread, here is the prototype Mosquito

Myself and another couple of guys will be building this one, hope you enjoy watching our builds

Dihedral is 4 degrees on each wing ... 44 mm under each wing top (or 88 mm total) ... see pic

The motor nacelles do not follow the dihedral, they are vertical so be careful to get the right nacelle on the right side, this is evident by the taper on the nacelle formers

I have the wing spars in 6 mm balsa, but foam and ply laminated (or similar) could be used

Getting started

Got the plans printed out. It's a wonderful feeling starting on a new model. There's nothing quite like new plans and a new box of foam to go with.

Whooooo great stuff mate ... You building it ALL from MPF Jeff ? if so, be a little careful as all the notches etc are done for 6 mm Depron and I know the MPF is a little thinner

Look forward to seeing your build pics and please let me know if you find any mistakes or miss fitting parts

I will get the plans printed and parts cut out but can't start building till my Foam-Tac glue arrives from the US

By the way, don't want to tell you how to suck eggs, but I find the best way to drill holes in foam (small holes) is to use a brass tube (or similar ... I have lots of different sizes) sharpen the end and press and twist it through the foam, push out the bit left in the tube with a bit of wire or something and you are ready for the next hole ... make for a very clean and precise hole

Almost all from MPF; probably break out some Depron for the tail feathers. I'll cut the plan slots slightly undersized for a good fit.

Hope your glue arrives soon!

Good tip about the holes. Are the holes marked on the fuse formers for pushrod locations?

It looks like F2 is glued half way into the tube formed by No 1 skin and half way into the tube formed by No 2 skin. (Makes sense.) Why are there two F3 formers?

F4 and F5 look pretty similar. Does F4 go all the way into No 3 skin and abut F5 all the way into No 4 skin?

Edit: I completely missed that there are two F2 formers. I can see that the idea might have been to have a former for each end of each skin, so you could built it section-by-section, and then glue the two formers together to join a pair of sections. That said, it worked out well on the Foam Casualty F6F to share a former between skins, so I'll do that here too.

Here's this morning's progress. Got all the fuse sections built. See pictures for details.

I'm going to go ahead and join the whole fuse and cut a hatch sometime after the wing is joined to install servos and run pushrods. To simplify things in this initial build, I'll put the elevator and rudder control horns on the outside of the model.

I'm going to figure out the battery hatch much later, after I have the model nearly all together and can ascertain the CG.

Hi Jeff, its looking great mate, sorry, I should have done a exploded veiw of the fuselage (as I did for the nacelles) done it now

Yes, I did extra formers so that there could be one in each side to build in sections and then glued together

Were some of the formers too small? or did you just cut them a bit on the small side ? do I need to make them a tad bigger ?

Good idea marking the centre of each one so that you know where the joint line goes ... I should have marked this on the formers

Line up holes are marked on each former

Yes, its a good idea to "mark" but leave any cut outs until after rolling as it makes for easier neater rolling

Also mate, good idea to leave the hatch till later, I was thinking to cut out the top section (above the wing) see pic ... this would also act as a hatch to fit the gear ... not sure where the battery will be located for correct CG

What glue are you using?

Anyway mate, looks like you are doing a very fine job and working out my mistakes and forgetfulnesses (is that actually a word ) I usually do this as I build and modify on the plans before posting .... sorry you have been thrown in at the deep end mate

It can't be easy working out what someone else has designed without proper instructions and info

Once the fuselage is together and the top section taken off, it shouldn't be too difficult to use the same "tube drilling" technique to drill a hole through for the elevator and rudder (one each side) see pic ... then you can use either plastic snakes or simply wire push rods

Lockey

EDIT ... Got my plans printed today

Started cutting out a few bits today, have managed to roll the fuselage bits and now waiting for glue ... I have CA, but not keen about using CA glue on edges

I used a pin to mark the outline of the wing cutouts through the pattern on to the foam, and then marked them with pencil ready to cut out when I am ready

By the way Jeff, I like the way you rolled the foam with the 2 pieces of dowel, what diameter is the dowel ? and how did you do it ? looks like a good idea

Thanks Lockey comming from you the expert means a lot ! Here is a PVC pipe rack I made to help with all the planes/jets storage dilemma . It holds over 50 builds suspended with string, wire or bungee cords.
