Well, I've started fettling the extrawot, it needs several major decisions made which I'll talk through.
The engine is superb and initially I thought it would prove too heavy at 1.2 Kg so I tried to swap it for a saito 36fg then I found that was heavier still so I am going to use the laser, principally because I have thoughts about scratch building a fw 190 A4 at about 75" wingspan and the cowl will swallow the laser.
Anyway the builder had had made a beautifully machined alloy spacer that took the form of a flanged tube, this weighed in at 200 grammes, but the big disadvantage was there are no holes to allow the fuel tubes to exit so I bought some 12.5 mm thick maple engine bearers and they weigh 60 grammes.
With these in place and with the cowl fitted together with18x6 prop and carl goldberg spinner it balances nose heavy BUT it still has to have the elevator servo(s) fitted at the rear beneath the tailplane. I find I need 160 grammes to achieve the correct balance. The standard servos weigh just 84 grammes for the two so I'll have to fork out for two metal cased digitals that weigh 63 grammes each.
The other problem is the servo for the rudder, the rudder is simply enormous and a 2.00 cubic inch motor on the front is going to introduce some serious aerodynamic forces. Currently the fitted servo is a futaba 148 which is going to be operating at full load just to stay in neutral so I linked up another one in tandem, works just fine, and it's a little more weight behind the c of g.
I'll update from time to time.

Well the mate that sold me the wot 4 has now sold me an extrawot, 6 feet span which he's built to a very high standard and now decided to go all electric so it's never been flown and comes with a brand new in the box laser 200 V-twin christ man this'll sound like a hog......
See and
I'm now as happy as a pig in s**t but sometime I have to explain to the wife where my pension's gone......

I just love my wot 4, this plane was built nearly 30 years ago and my mate sold it to me in april, a weekend hasn't gone by (when it's flyable) when I've flown it.
He originally fitted it with an OS 61 4 stroke, long since discontinued but I pulled that out and e-bayed it and got the best part of what I gave for the whole plane back.
I fitted a saito 82a, and this is just a bit too powerful forit, wack the throttle open and she does half a torque roll, leaned out whell do 3 vertical rolls before falling off the top yet will slow down to walking pace.
Before I bought it I'd assembled an artf of the same plane, fitted with a saito 82 as well and I haven't flown it yet.
If you get the opportunity to try one in the states go for it ideal engines are OS 46 fx or ax some folks fit the 55 ax.
In the uk the artf is actually cheaper than the kit. You can see them on look under the Ripmax collection.

A couple of posts ago I mentioned about the Flying Dutchman and his half scale bleriot that he was hoping to fly across the channel, he didn't make it.
10 miles into the flight the engine packed up and he had to ditch in the english channel.
Though we informed both the british and french coastguard agencies, one ship diverted and recued the 1/2 scale louis bleriot and another ship, a dutch sailing/training 3 master picked up the plane and reunited it with its owner.
He came across to the UK by ferry and we had a consoling drink together.
Unabashed he now plans a 67% bleriot (remember the guy also flies a full size one and crossed the channel in it in May this year) which he is going to fly in the shows round europe next year.

My first son's mother and I were divorced over 25 years ago, I looked after my son right up until he left university when he went to live with his mother in London in the early 90s. We hadn't seen much of one another since except when I was in a clinic for surgery to remove a particularly agressive cancer about 8 years ago.
He is a self employed consultant to a large government run department and, as his second job, he has a rock and roll band which is kind of in the "2nd" division, he also has his own record company and freelanced for virgin media writing and producing songs for american girl acts trying to break in to the UK market. He's toured the midwest in the states but his biggest fanbase is in China where he has had several tours.
He played around a lot like rock and rollers do so I was amazed and delighted when about a year ago he announced he was getting married.
The wedding was last weekend aboard the HQS Wellington moored on the thames in london, google it, it's a hell of a venue.
I was the most laid back wedding I've ever attended the registrar had a fit of the giggles (she was a she) and both my son and his bride were literally laughing all the way through.
The booze was flowing and he asked me to address the wedding party. I'm not an extremely confident public speaker but I'd not had a drink then but I made a brief speech that halfway through had he and I on the verge of tears, filling up we call it in the UK, so there was a pregnant pause that...Continue Reading
