It is slowly shaping up and starting to look good.I look at the wing and the resulting airfoil and I think it can't help but be fast those motors will put out alot of power and it should climb like a home sick angel.

Got a couple more hours work done on the twin finished construction of the nose and battery compartment with its hatch and mounted the firewalls. Hey what do you guys use for a body filler like bond-o? I want to find something I can fill in nicks and gaps with .Do you guys have any favorites? Id love to find something light and easy to sand like micro-balloons. something light enough to create fillets and fill gaps Gorilla Glue is great for filling gaps but I want something that will sand down to a nice Finnish.   |

View AttachmentView Attachment Filler, no. I don't have a favorite. Everyone suggests spackle. Lightweight. Lightweight spackle sucks. It doesn't flex in the least bit, super easy to crack. Like it cracks when you sand it, or look at it funny, before the plane ever gets in the air. Then I tried the fiber reinforced spackle. Slightly better.... Slightly. I have put some wood filler on the P-36, as I am kind of using this as an experiment with different fillers. It hasn't cracked yet, but I haven't flown it yet. My thoughts are wood filler should work better, since foam kind of expands, contracts, and flexes like wood. Drywall does none of the above, which leads me to believe spackle is not the filler of choice. Bondo could also be acceptable. Everyone recommends lightweight spackle because of weight. I don't think we are loading our planes up with enough filler to matter, could just be me and how I use it. Either way, if given the choice of the lightweight stuff, and no filler, I am going with none. I think if you are trying to sculpt huge compound curves, entire cowls, and other things with filler, it is probably time for you to look for another medium to build your planes with than dollar a sheet foam. Yet again, that is just my opinion |

No I agree with you there . I don't mean to sculpt large structures just to fill in some dents or gaps.I have some epoxy type body filler for repairing plastic car parts I may try that stuff.

View AttachmentView Attachment Very very nice! great work going on there, thats going to be one sweet looking bird! I don't use filler so can't help you there, I am usually just cleaning up seams with diluted wood glue. I did use LW spackle once on my first snow skimmer and yes it does crack easily, not an ideal filler IMO. I find GG sands out pretty good with 320 grit but again I am just sanding trailing edges where the GG squeezes out after expanding, and most of that is trimmed away so the cut makes it smooth already. Sorry I have no useful advice for you .  |

Not a problem leaves it open to experimenting there was a product that I use to use in the balsa wood days but dam if I can remember what it was use to smooth to it out with a finger wet with water. I think I'm going to try wood glue on the small stuff. I want to smooth out the nose block I have epoxy based plastic repair compound I may give that a try just to smooth out the imperfections in the foam block. Im planning on going with minwax poly and shaker can paint.

Just when you gloop glue up like that it takes a day to dry. |

I got some work done on the engine nacelles and the Nose Block I tried out that plastic repair compound it's used to repair plastic car parts tried it out on the nose block and it worked it seems to be a 10 min epoxy mixed with micro Balloons but is sands easy and I used it to fill in some of the imperfections in the nose block need to put a second coat on the top just to even things out. The stuff is heavy so you wouldn't want to use too much of it but on the nose of the plane should be less of a problem. Im getting excited IM starting to imagine the maiden flight LOL.  Attachments:

You guys don't have them in the states but i got this stuff in a car repair kit at Canadian Tire I live right next to one so they are handy for glues and tools and stuff like that but i think you could get the same stuff from a hardware store or even walmart or Princess auto.I smeared it on the nose block and it now has a hard sand able skin with a foam core.

Well got some more work done glued on the tail feathers and the top of the rear of the fuse. I'm going to have to start getting into wiring this is were I have to pick my fellow modelers brains as Muti-engine are new to me . Do you think 14 Gage wire is heavy enough for the run from the ESC to the battery or should I get some 10 gage? The run form the ESC to the battery is about 9 inches.  |

I have used 12 gauge on my P-38 and DH-88 and when I have had to lengthen battery wires, 10 might be a bit overkill, 14 is probably sufficient for your needs there. Build looks fantastic!!

View AttachmentI usually just run whatever wiring size the escs have into a single xt60 plug, then just plug the battery into that. Here is a good write up. 14ga is plenty. oscarliang.com/wire-awg-chart-quadcopter-rc/I have 12ga on my 10 inch battery lead before the y adaptor on my jet, and about 80a goes through that absolutely fine. Plus, 10ga is harder to solder.... and squeeze into a xt60 plug. I tried to squeeze the 10ga wire off a battery designed for a xt90, as I snipped that off, and it was a pain. |

Thanks berko I have a spool of 14gage wire anyway so I will use that. I'm at the stage were I'm going to have to run all the wires and install the alieron servos before I can finish the wings and install push rods before finishing the fuse.

Well I got the wiring done in the wing and installed the ESCs and the aileron servos and tested the motor setup. " HOLY CRAP!!! the trust at full throttle is crazy I only have some 3000Mah 3S Batteries and on 11.1 volts the wing just about rips out of my hand it will be insane on 4S. The bird is turning out very light so far so I have a feeling this thing is going to go like stink! when I tested at full throttle it blew just about everything off the building table that didn't have any weight.  |
