That was cool, it's got a bunch of lift. Then I watched the RC fly and the one thing I noticed is the tail wheel is about useless as it was mounted.

Bonified Wingnut

Yeah the tail wheel I still have not figured out how to make it steerable and semi scale. The main landing gear seems too close to the CG and it looks like nose overs are common. I will try to get it as far forward as I can and still look scale.

Hi Wingnut, I just found your build thread, very interesting subject. Makes me think back to my stick and tissue days. I think if it were me I would go electric, it just seems to fragile for glow, not to mention the hassle of starting 4 glow engines. Looks great so far!

I was thinking the same thing as Cal but electric also brings it's own little problems. I have always wanted to build the P-38, my all time favorite war bird but I flew IMAA for years and have seen way too many engine flame outs then crashes when the pilot would turn into the dead engine so I have backed away from building a twin. The four engines wouldn't be as big of a problem unless two engines on the same side flamed out and the odds are against that. I would just feel safer with the electrics.
Starting four engines isn't a big deal to me but it is a lot easier just hitting the throttle. That wonderful sound also wouldn't be there. Tough call.
We had a regular pilot at the IMAA events that had a scratch built with 6 glow engines. I watched him start it many times and learned how it's done, takes a little more time but the sound is worth it.
Now we have the good batteries and better motors but I just haven't had the money to build that 38 I like so much. That one in the video is really fantastic and the plane is very good in the air. Looks like an easy one to land too.

I agree with you both. That is the reason I finally decided to go electric. I just sold the Thunder Tiger 07's and AP 061's I had for it. I was waiting till I got to this part to decided. Making fuel tanks,finding room for throttle servos, trying to get 4 small engines running...etc If it was a little bigger and I could at least fit .10 or .15's on it I probably would have used glow. I have been flying electric for a few years and don't see a problem with it. In fact at one time I started converting everything to electric...but after a year or two of finding out how inconsistent Lipos are I went back to fuel. I like the duration of fuel and the sound. To get the performance of an electric you might have to get a little better engine but you also end up with longer flights. The idea of spending a few hundred dollars every year to replace batteries I don't like. So I end up using them way beyond their time. But having a few electrics for special planes like multiple engines is probably the smart way to go.

I was not happy with the Job I did on the lower wing. I used way to much CA and it leaves a hard coating. I am going to try to do better on the top wing and maybe slow down and try to put some interior details in this thing. If I ever built the plane again I would make thinner formers out of ply or something so that the interior could be scaled. The way I filled in the nose will prevent much of a scale job but I can still make it look better.

I only have one electric but three of us got together and ordered all our batteries from Hobby King to defer the shipping costs. Most of the guys at the field do the same thing and have had very good luck with there packs. With the U.S. warehouse shipping isn't a problem these days.

One of the things I like the most about internal combustion are that as long as you keep the mixture right and let it get some air they will take a lot of misuse. A few dollars worth of fuel and the engine will be around for years. Electric has its advantages.

I will be back to work on the H.P. 2 in a day or two. I picked up some Gorilla brand wood glue the other day. I was thinking about trying some. The problem I have with CA is the caps. After decades of using it the only solution I have come up with is to buy about 5 extra caps per bottle of CA. I also have some of those really thin nozzles but I forget to use them and then the thin CA goes everywhere. I need to pay more attention. I might end up liking this plane and wishing I did a better job.

I usually just stick a pin in the top of my ca and it seems to keep very well, my problem is that I am so damn allergic. I bought some of the super phatic, not as good for wicking into extremely tight fits but it does wick into so so tight joints. I some times put a drop or two of ca on a scrap of covering and use a t pin to apply. I have not tried the gorilla yet, but it does expand so holding the pieces together is a must(I think).

Yes I can see it is a tough decision to go electric or glow and my biggest concern on your build would be the seemingly fragility of the nacel to wing structure. Can't beet the sound of 4 IC's running tough, I bet

Bonified Wingnut

I use pins but what happens is a little glue sticks on the pin and then when you pull it out the glue plugs the hole...so you push the pin back in and it just moves it out of the way so when you pull it out the nozzle gets plugged again. I don't mind buying the extra lids it keeps the nozzle good. The only other problem is the fumes will start to build up on the screw cap and top of bottle and eventually you cant get the top on. i dont think this type of Gorrilla glue expands. I will test it to make sure. The other kind is great for sheeting to make sure you get contact.

I just had several friends here for a few days, lot of fun but I'm pooped out. I still have planes and gear in my van from flying Monday and picked up a bunch of stuff from a lady that is now a widow and her husband was a builder. Some very good stuff too.
I use the thin long tips for the CA and just nip off the end when it plugs. I also have a small jar of acetone that I soak the caps in if they plug. Works great. I buy a big box of those tips and they last me for a couple years. Almost time to go buy more though.

Bonified Wingnut

Acetone. I will try that. Thanks.

Bonified Wingnut

Ok distractions in too many projects but back to the Handley Page for an evening.




Couple more things to figure out. Not sure if the tips are supposed to be solid balsa block or just the leading and trailing edge.



These hinges aren't making sense either. I will assemble the wing and aileron and get a better look.



Wow I can't believe it has been 3 weeks since I worked on this.
On a side not I have got some done on a couple other projects.



And


And other stuff. I would like to get the H.P 42 ready for electronics soon

Hi Wingnut,
I just started the building of the HP 42.
No laser cut for me. I cut myself all the part.
Your thread is very helpful.
Any update on your step by step building ?
Thanks.

Bonified Wingnut

Still on the building board right where I left off on the wing. If you have any questions I will be glad to help with what I can. Maybe when you get to where I am you can get me to finish it...lol

Bonified Wingnut

If you would like please post your progress along with photos on this thread. It would be nice to have another example of such a cool plane.

GoldWing83

Hello, I'm there.
I started this wonderful plane.

I had first to cut every piece of wood, because I have only the drawing (no laser-cut kit ...) :


I have a large wood board for the building, with room for the tools and all necessary items.


Fuselage assembly left side, in parallel with the right side I made a mirror copy of the drawing in order to have both sides) :



I have now some difficulties to "read" the drawing for the installation of the stringers A, B and C.
It seems that they should be on a curved profile, but its a 1/8 x 3/16 ...
I will figure out later.

Bonified Wingnut

Good start. I don't envy all of the cutting..lol.

GoldWing83

Yes, you right. But it's done, now ...

Continuing by sanding the extra 3/16 x 3/16 :




The two sides of the body are now ready (you see I have a good guide note ...) :




Then, starting the assembly of the body :



The alignment of each bulkhead need to be checked :


Let dry :

Bonified Wingnut

Your doing a much nicer Job than mine.

GoldWing83

Not sure. We'll see at the end ...
The drawing is very difficult to understand in 3D.
Fortunately, I have your notes.

Bonified Wingnut

Yeah I wouldn't rely on mine too much...some of it was a guess because I agree...hard to understand. I was getting some photos from a guy in Thailand that was building an upscale version for 4 .52 four strokes. I have since lost contact with him.

Bonified Wingnut

Anything new Goldwing83?

GoldWing83

Away for a couple of weeks for my job (Vandenberg (CA) and France).
With the heat coming back in Arizona, I have some time to built ...

Continuing the body assembly with the upper bulkhead installation completion :

The two piece of metal allows to keep the alignment of the body all along the assembly.

Now the bulkhead are installed, I need to install some spacers to keep a flat reference and to allow to check the squaring of the frame.
