Only 7 flights with the Warbirds Hurricane today, fingers freezing, not only mine but the younger flyers.
Early finish for all.

Nigel.Don't use the Uhu as a contact adhesive unless you can garrantee getting the position right first time,
For a job like that I usually coat the ply, put it in position, making sure it can't move and leave it overnight.

I just used 2 8mm steel washers Brian.

I'd have lost patience and built a replacement myself 🙂
Me too, many of the aeroplanes are limited runs and spares run out. I've repaired foamies for people who were going to bin them due to lack of spares.

Hi, GG,
The stress cracks mentioned were regarding a Percival Prentis by the same designer caused by a heavy landing. The method of separating the fuselage is not the way I would be happy with as it is at a point where a 3 point heavy landing would create a lot of stress but Robin Fowler favours it and it seems to work for him.
Early Fw Condors were prone to go at that point.

There is a 96"span Dc3 balsa build on the forum. Robin Fowler design, the specification is just over 9 lb two 3s 4000 batteries , inexpensive small motors. And it's fitted with retracts. It can be done.

Yep, agreed - nice, but just a bit too big, too heavy and too heavily loaded for my flying fields. I think the 60-odd inch size that Eric is talking about would be the sweet spot for me, for a Mossie. So much so that I managed to resist a 73" span CMPro one that went to auction on eBay at the weekend and went for a song. Didn't look half as nice as Eric's one there though - the CMPro one has quite a portly fuselage and there is something about the nacelles too.
Just looked up the CMPro Mosquito on YouTube and it looks too short making the fuselage look porky, the nacelles look oversize probably to accommodate the motors fuel tank and retracts. Mine are wrong too the front lower cowls are Spitfire.

What type of foamboard did you use? The Hobbycraft stuff or something more exotic?
The lower wing sheet is Hobbycraft foamboard and the top sheet is Maker foam board as it is easier to form.

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. ☠️That's why I made mine from depron and foamboard same size less than half the weight. At present uses 2 3s 3000. It would be better about 60" with a single battery. I tend to fly the 110 more as it is one piece, twice as many flights with the same batteries and I can hand launch it myself. Now I have the dolly I will see how the Mosquito goes from that.

A grumpy old bachelor I used to work with refused to contribute to a collection for someone getting married. He used to say I'm not paying into something I have no chance of getting a return.

Nice Geoff, some details please.

Any twin about 60" span will fly on a single lipo if built light. I know my Whirlwind and 110 are made from foamboard and depron but a balsa model could be made almost as light if no undercarriage is required.
My son built this 110 from a scaled down Brian Taylor plan. It is 58" span and had 2 small Axi motors pre lipo it had an 8cell Nmh battery, great flyer. I made my depron and foamboard version from the same plan. Mine has two Racestar 3536 950kv and a 3s 3000 battery.

I've always been a fan of extra aeroplanes 😃

She looked rather nice up the field today. The engine is running solidly after some tweaks to the top end, and now has enough compression for reliable hand starting. I reckon the idle is still going to take some settling.
I took her for a little drive round the runway - very nose happy, even though the grass was cut this morning. The ground is still pretty soft, and the Club Press says it's not short-short yet, but I think I'll shim the UC mounts for some forward rake, and maybe consider a flight mode switch to give me full elevator on the ground.
@GrumpyGnome gave me a second opinion on the CoG (a bit difficult in the wind), but we think it's about right, especially considering Martins experiments, and the 3/8" each way elevator.
I just use high rates for taxi and take off, and low for normal flying depending on conditions. Don't think my brain can remember where all the switches are.😄

Another day at the field with the Warbirds FW190 and Hurricane + the BT Corsair 9.30 am till 4.30. Not as warm as yesterday but good flying weather. A good turn out again quite a lot if banter, 16 batteries to charge, took more but it started spitting on to rain which stopped when we reached the car park.

After many flights with mine I'm happy with belly landings, It's flying so good I don't want to change anything.

Great day's flying today with the Warbirds FW190 and the Brian Taylor Corsair. Fingers crossed for tomorrow.

I think that I was a bit too subtle for you Eric!
I'm going to be posting the order forms out on Monday to those who have confirmed their desire for a Tempest .

PS I know my humour can be an acquired taste!
I normally spot quotes like that Ron, must be slowing up in my old age. Or it could be the excitement of a sunny day and light wind, the first since Easter and the rush to go flying.
