OK guys.......
I have a question.
I am trying to complete covering the entire model. Execpt for a little bit on the tail I have to cover the necells.
My question is, Can I glue the fans in than glue the 2 necell halfs together without having the motors???
I have not decided on my power plant yet.
Am I forgeting anything before I glue the halfs together and than mounting them to the wings?
Thanks Guys

Perhaps I should wait for your report..!! I finished my major flap and servo cuts, Carbon spars etc.. With still only a few non specific livery ideas... Some require painting, others would be vinyl coating.. That would direct my way..!!

I looked at this too during my build, the problem arises depending on how you secure the fan blades to the motor, and can you get access to do this once the pods are sealed up?

I would hold on this till you have your powerplant in and tested.

As for covering, this is my first build of anything like this. I found the light tissue and WBPU very simple to do even for a first timer. I just cut the tissue into long strips. Painted on with wbpu from the site I mentioned earlier, it somehow smooths to a clear coat (without brush strokes being evident) A couple more coats of this stuff and the plane is as hard as rock. If i threw a fair sized pebble at it, it would bounce of without leaving a mark not to mention leaving a nick on the sealed paint job I can see my plane standing up to heavy handed hangar abuse (minus the wing tips of course !) Going the vinyl route seemed too tough for a newbie judging from other posts in this thread....that and the fact I was scared of melting my plane

the tissue and wbpc worked great for me after more than a year
of flying and being used as a demo model mine look Brand new
till the wing snapped and came off .

the engine pods I cut the bottem one and installed wood mounts
on the top one - then glued the front part together the back
bottem was held with pins in the front and strong magnets in rear
easy access to fans

The weather has been really rough down here lately, along with being back at work, I have been struggling to find time off when the weather is calm to maiden. It will happen though

Thanks guys for the reports on gluing in my fans.
Major... Duh??? Your right. How would I ever attach the fans??/
I am just getting close to finishing the covering and I wanted to finish the necells.

Pulsery,,, Thanks for the picture of the "cut away" if your necell. I remember seeing it in a earlier post,,,but just didn't want to go thru them all again to find it

Now a question for all the successful 737 pilots. What motors should I go with??
I have 2 new 100 amp ice speed controlls from another model that I want to use.
I bought the fans that Ming had to offer (Changing sun).
Again I read many post on what the guys are useing but kinda blew it off untill I needed motors. WELL, now I need them.
What motors and batteries should I get to go with my fans and esc's

Thanks again Gentelman

I used the Scorpion HKII 2221-8 3595hv with 2 4cell 3000mil
lipo's and mings stock fans , works great lots of power
in crash video you can see the 737 got off the grass quick.

I also have the CS 10 blade's which I used HK 2800 kv motors
nice sound but less power - good if you fly from paved

Here is another way to get access to your fans by making a simple hatch.

Cheers

Nice craftsmanship on the hatches. I don't see how you are able to remove the fans for service though.

Yikes,
just seen your video, that would kill me! Is above just a passing comment or do you think the tissue/ WBPU lead to the wing failure you had?

I am considering strengthening up the wing now, although i wish I had of done this as one of the first steps. I am worried about weight and structure load. I don't intend on doing any loop to loops with this, if anything I will be aiming to fly gentle without to much g force where possible, but I guess looking at your video, you were not putting your plane into higher turns that would be expected.

Worrying!

I belive the wing failure was caused by the high gusting wind
if I were not flying the demo , it would have been to windy to fly.
the wing seems to have failed down , most likely
cause by a gust of wind in the turn.

many others are flying and they are ok ,so I would not worry

just don't fly when its 20+ with gusts

as for the crash - its happens

Do you think the addition of adding flaps / cutting into the wings may have reduced its integrity? This is another addition I am looking at doing now, but looking closely at it last night this was my main concern even if the wing length is reinforced with an extra carbon rod. As i'm sure mine is more of the heavy side, I am expecting possibly more wing loading forces on mine.

Also, can you advise me what would be the best esc / batteries to upgrade to to suit the wind rider motors? I dont think i will risk the 65 ESCs now after your advise on over heating. I would rather leave nothing to risk :-)
Thanks
Gav
