Well as it's my birthday in a few weeks time I've made my wish list and sent it up the chimney. I know that's what we do for Christmas and I know that I've got a wood burning stove, nevertheless I thought it was worth a try.

Graham ,

I think you would be better off with the smaller La7 as it works so well in electric form . Might have to deal with that separately at a later date.

Anyone out there that wants a big La7 better put their hand up . The last batch was in 2011 !

Not likely to get a second go on that basis . Dont want any "grizzlers"crying on the phone after the boat (aircraft carrier) has sailed.

Guess I won't see one now

Well, thanks to jrman I will soon be in possession of an LA-7. So my winter project will soon be queued up in the workshop, just got to sort out a new motor for it now. Jon, are you listening?

@Richard - retracts to suit incl oleos and any other bits for the build?

Trying to keep you listening, Jon isn't!

The retracts will be the same as the 110 , as will the oleos . The machine shop is on shut down at the moment but when they come back I will order some more units . The only other item we will produce is the decals .

So far , nobody seems to be posting any pictures , so I can only assume we are a long way from retracts and decals .

Hi Richard, for a change started backwards with the wings first, adding a 1/32 ply strip to the bottom trailing edge as I found that with my usual hamfisted approach to loading the car the trailing edge of my small la7 got damaged, hope that this may help. however am now stopped waiting for retracts, don't need the oleos yet , when I have finished the wing will publish photos

cheers

Peter

A big thanks to Graham & Dennis for carefully packing up my LA7 and bits which arrived today.

Must show great restraint and not drool on the veneer as the BF110 has to come first.

Graham , isn't there some proverb about the bolts and horses ?

There was a long list of chaps in the La7 waiting room . Preceded by a long list of people in the Hurricane waiting room .

I believe that all those in both waiting rooms, got their kits .

Did you not see to sign to the waiting room ?

Did you only buy a platform ticket ?

Were you buying a coffee and a doughnut for eight weeks ? Stuck in the Lav ? Struck down with disentery by a National Express pork pie ?

Or am I thinking of the one about the crying wolf? Or is the boy that's crying ?

Anyway , a worm's involved and probably a bird with or without a bush .

Hi Richard

In defence of my case, I did put my name on the 63" but you put me off suggesting that the smaller version would be better for electric.

I'm sorry I missed the bird with the worn that went after the horse without the bush. See how distraught I am. Now full of gobbledygook.

Just thought I'd try

Kind regards

Well Graham ,

Patience is a virtue .

Although I dont think she was when I went out with her , Or am I thinking of Olive oil ?

Anyway ,

lets carry on with this 110 and see what transpires.

As my Mum always said , "You never Know what's round the corner "

( she had tunnel vision )

Terrible business , but it kept her focussed .

On the horizon, mostly .

I knew a Bloke who was blind in one eye and couldn't see out of the other one, so they fitted him with a glass eye. He couldn't see thru that either so he drilled a hole in it.......it was OK then.

All's well that ends well I say

I've had a closer look through the kit and I'm listing some first thoughts/queries:

The ply doublers are about 1/2" deeper than the fuselage sides in front of the wing, I'm guessing that this is a cutting error?

I think I'll be using my fuselage jig to attach the sides to the crutch, and using some ammonia solution to get the sharp bend in the sides over the wing cutout. Otherwise I can see some vertical bow developing.

Control runs need to be planned before anything else is started so that snake/closed loop runs can be cut where needed. It looks to me as though they will have to pass through the crutch so it might be easiest to cut holes for outers to pass though with the wood in the flat. It's a long run for plastic snakes so I might go for wire in tube to reduce slop. It all depends what I can find in the recycling box.

Aileron and retract wiring, I think some 15mm copper tube should do to bore conduits.

Wing bolts - set compression blocks into the wings or ply load spreader and tubes through to stop the foam compressing?

Wing traing edge - how hangar rash resistant is the brown paper on such a fine edge?

The tailwheel - any suggestions? I'm tempted to make it spring centered castoring to save making fiddly linkages. The spring could be buried inside the fuselage easily enough.

quick notes, if you look on the laser listing you will see the add on pieces for the front of the fus and rear of the wing seat, the sheet of 1/8 is not quite deep enough to take the whole side so glue on the missing pieces, as a help I raided my scrap box and added some 1/4 square along the top of the side pieces, this gives a nice solid shoulder for the lightply to rest on rather than a butt joint, I also took 1/32 off the sides of F3 as with the ply doubler in place it wont sit flat.

I did have some problems with the wing trailing edge ( on the smaller model) so I have added some 1/32 x 3/8 ply along the underside of the trailing edge, gives it a bit more strength for no or very little weight. On the small model I I used Sullivan snakes, rudder under the crutch plate and elevator above, if you do that put them in place whilst the top and bottom are open, I used a fixed tailwheel and that worked ok.

Hope some of this may be of use to you

Cheers

Peter
