Hi Mike,

I got the kit and parts during the week. They came here surprisingly fast, good service from Avetek. I haven't yet opened the kit, been too busy with work etc. Was surprised at the ply parts included, before I realised they were fuselage jig parts! Good thinking, I have built too many banana shaped fuselages Wink

The propeller is being doped, I will put the last coat on today or tomorrow. Then it is balance point time, will see how much this one needs. The engine is still not glued in, that is the last thing to be done (will do that after gluing in the needed noseweight). Noseweight of course depends on how much rubber goes in, any suggestions of where to start on that? 8-10 grams of rubber? I have a rubber cutter (Harlan made), so I can make almost anything. Have a box of Tan II 1/4" and also a box of 1/8" Tan II. Thought of doing a 4 strand motor, maybe braiding it.

3 loops of 1/8 has worked for me. Start out with short motors
to get the feel of the setup then add length for duration.
Of course added length requires more nose weight.

Thank you Mike, will start cautiously.

Got the pilot today from Dave Banks. Nice work and weighs only 1.6g. I'll have to shorten it so it fits in the cockpit, so it will get lighter. Feels like cheating buying this kind of work, for the next one I'll probably make one myself. This one serves a purpose, it shows me what can be achieved!

Haven't done that much lately, as there is no hurry. Winter came back with vengeance, -8 degrees Celsius this morning when I cycled back home from night shift....

And they are very reasonably priced!  But the shipping can be costly.

The pilot was reasonably priced, actually cheap I think considering the looks. Good value for the money spent.

Made some teflon washers today. Bought a leather tool, it worked very well on teflon, too Wink
Got a teflon bar from a friend many years ago, I cut slices from it. Hard to cut thin slices, so these washers are a bit thick but I suppose it doesn't matter that much. At least they are round now.

The sign of a real aeromodeller,  making everything you possibly can.  Well done. Much more satisfying.

Free-wheeler from the Avetek parts. Easy to do, hope the joints I made hold!

Tommy

P.s. Re-made the last joint. Used soldering paste and hotter iron = a better joint.

Nice work Tommy on your prop. Do you have a backup just in case?
I'd be afraid if I had one it would snap off at the boss, then I'm S.O L.
Very nice solder work...nice and clean.

Hi Skyraider,

I actually made two propellers. Thought of using the first one on next project, that might be the Avetek Tiger Moth.

Shortened the pilot today, it now fits nicely in the cockpit. Not far off from being ready!

Tommy that really looks the part. The pilot just makes it. I don't recall whether this is for indoor or outdoor. Can you fly outdoors in Finland at this time of year?  Hope to hear some flying reports soon

Whenever possible, fly with the sun at your back

Thanks for the nice words!

This is mainly meant for outdoors use which unfortunately means that the first flight will have to wait for better weather. There is no way I could try this out now, it is wet & windy. Good building weather...

I'll make a six strand motor for it, three loops of around twice the length between the prop and rubber dowel. Check the C of G and put in the appropriate amount of lead. Curious what the final weight is.

Glued the pilot in today. Made a rubber peg from 1/8" aluminium tube.

Weight empty 48,5 grams. Will see how much noseweight goes in!

Tommy

P.S. Any advice on the balance point? 1,5" behind the leading edge of top wing on instructions, works fine?

Sorry for being quiet on this front for a long time, summer just flew by and I never got around to adding noseweight. Hate it, as usual. Added around 15 grams inside, behind the front former and the weight now is 63.3 grams. Slightly noseheavy now without the rubber, should balance quite near now as I did move the rear peg forwards. The rest of the possible lead needed will be glued on the back end of the propeller assembly, don't want anything visible. Glued the engine on, could have of course made the first flights without it (which might have been actually wise....).

Weather is awful, as usual for this time of year so the flying bit will have to wait for nicer weather or an opportunity to try indoors.
