Next up on the building board is the Tony Nijhuis Harvard. I am hoping it will be a quicker build than the Mosquito, which took me 2 years.

This will be built for electric power and possibly with a sound system.

I am still pondering battery position - will try and get it as far forward as possible.

Cut the parts from the laser/cnc sheets.

Then started with the fuselage.

Nice, this will be interesting. I've always fancied a Harvard. Mind you, like most modellers, I can probably say that about 40 different prototypes!

That looks fantastic Jez. I have just had a look at your album.

I may be asking questions as my build progresses - if that is OK.

Thanks Jez.

First question is:

What motor and battery are you using and did you manage to get the CofG correct without having to add extra weight?

Cheers.

Geoff...

oh...... and what is the all up weight (mine always come out on the porky side)?

I've put this build in my diary Geoff. Glad to see it underway and look forward to more details.

i have built in to the front of the fuz a sloping tray for the lipo and a removable cockpit as well see the pictures below , the all up weight at the mo is bang on 3.5 kg and the c of g is not far out but i haven't fine tuned it yet as need to put the wing servos in so will need a bit of weight in the front yet

hope this helps

Hello Charles.

I have a set of these so will probably try them and see how they perform.

Bottom stringers going on tonight.

Thanks Percy, an interesting tip. I think I will probably need nose weight though.

I will take a view on the retracts when I get to building the wing.

A little more done today:

I think I will drill some weight reducing vent holes before gluing it together.

I had to trim the former to fit the battery box before gluing in.
