*Ming, why don't you make stickers for almost the whole jet for blue livery since it has all those curves and lines. That would be SUPER easy for us to just stick on!

Danny
The official blue livery sticker area too big, too heavy and too many curves surface.

I have all the respect for the engineers at Multiplex, having 2 Easygliders, the Cularis and a Blizzard. But Im not sure that the Elapor and the EPO are the exact same material. Similar, yes - but not the same.

The engine pods are placed at a critical point of the wing and, has to be secured 100% to ensure the total strength of the wing. When gluing in such critical places its important to prepare the foam with small holes, so that the glue can penetrate into the foam and make a stronger joint. Nevertheless I will follow Mings advise and continue to use epoxy for this plane.

Just painted lower half of fuse, (+13 grams after painting). Used Design Master Spray Paint which I've been using for a while now on my previous projects.
I will be painting the upper fuse tomorrow with Valspar Spray paint with Valspar Primer & Valspar Gloss (white) for Plastic, just like one I used with the Qantas.

Looks good Spyro37!

Nice to see that someone is progressing with their build!

I'm progressing slowly. Only 11 days to maiden day. All servos and the accompanying servos are mounted and moves correctly

Next is the fans. Going to test them tomorrow and continuing with the installation of them after the tests. Unfortunately I don't have a proper testbed so I can't measure the static thrust generated...

I also have finalized the graphics, and I will have all logos and markings cut during next week. Hope to conduct taxi tests next weekend

THANKS BEN.
Tomorrow, another 2 hrs. of work on her for top fuselage paint job, plus another layer of gold pin stripe over the white, so that the lower gold stripe will meet the upper gold striple. In short, the gold stripe on the above picture is not the actual width, it will be twice as wide.
Just waiting for the all the electronics, decals, Chrome tapes, and missing wood blocks for the gears for the flight video. Maybe take a day off and enjoy her soon maiden.

Beware!

One 737 use 4600Kv motor with 4S battery cause flutter on the wing tips during full throttle today in Hong Kong. Luck the pilot able to land it safe.

not good, not good at all... My vinyl coverd wings are now much stiffer than the bare foam, so I'm not that concerned, but I do have some questions Ming, to sort this out:
  • How was the winglet attached to the wing? Glued, or done in some other way?
  • How was he flying? diving, level flight, full throttle?
  • When you state the kv of the motor, do you suggest he was flying too fast?
  • Did he use the stock fan?

Thanks!

How was the winglet attached to the wing? Glued, or done in some other way?---glue.
How was he flying? diving, level flight, full throttle?---level full throttle flight.
When you state the kv of the motor, do you suggest he was flying too fast?---Yes, sure too fast we can see on the ground, it even faster than some of foamy fighter.
Did he use the stock fan?---No, is Lander 4370kv metal fan.

Don,t worry, it will be OK to use less than 3800Kv motor with 4S battery.
That why we choice Scorpion HKII2221-8(3595Kv) for our combo, it good for 3 or 4S battery.

To fly fast is not difficult at all Realistic scale speed is what I intend to achieve, reducing power at cruise and only use WOT on takeoff, and in emergencies...

Sure you can feel relax on your 737 maiden flight(when?).
Reducing power at cruising and enjoy the realistic scale speed of landing.
To landing this plane is too easy I can say.
