UMX Beast Profile

I wondering this would interesting to anyone who flies indoor often. Anyway, now that it's becoming indoor flying season I've decided to make my own scratch built profile foamy of the E-Flite UMX Beast. I wanted it similar in size so i used a 3 view that I've found on google images and resized it to my preferences.

I have foam piece cutout and trial fit before painting. Hope the painting doesn't add too much weight as it's 15g barebone. I'm planning on using the p-51 motor/gearbox/servos..let's just cross my fingers for 35g AUW.

will upload pics as soon as i find the camera.

thats brilliant
also i think that will fly better at 3d than the e-flite version
how well does it fly and what foam/equipment are you using?
also can you do some plans and a video cus i want to build one

Haha, that's cool, very ingenious too !
Perhaps the maker wording ought to be HORIZONtal or something, just in case.
Would be great to see this next to a real one, in flight.

I did something similar with the UM T-28 and 4-Site before release. Might be a trend starting, for those who just can't wait to get or won't be able to get the real thing.

Best wishes for the skies with your build

Thanks guy. Glad there's interested people here that thinks like me.
But i will buy the real thing but i like anticipation so i'm waiting
I might be able to get some plans but the video will come after i get a new camera!
But its all 3mm depron using the same gear as the P-51/4-Site.
But i haven't flown it yet as its always windy here but will soon at an indoor facility! Will let u know if i can come up with some plans.

It would be best to use 2mm depron and .5mm carbon rod for the lightest results! Weights should come in around the same weight as the e-flite 4-site!

i love bipes!

If u guys end up building with 3mm depron, make sure u pinch around the LE and TE of the plane to reduce damages when crashes occur. I've found that when i do crash, the plane itself doesnt get touched but the motor mount pops off!
Any tips on minimizing this from happening?
What glue do u use to absorb the shock on the motor mounts!

No idea with the gear you have on it, but normal hotglue works very well for little motors up front. If applied sparingly, using a toothpick for example, it bonds strongly and soaks up a lot of vibrations and impacts. Just swipe the toothpick on the well heated stick/hotglue gun end, to not leave those whispy awful lines of glue and then quickly place on the area.

It's a tiny brushed motor w/ gearbox from the Ultra micro p-51 mustang! Motor has enough power to hover and do aerobatics w/ 1cell 160mah lipo. But i think Hotglue would weigh this micro down but alot as this model weighs 34g-ish.

Bare with me!

Ok trying to get the plans accurate has been a challenge so far and it seems like it's going to take a little longer for plans. So until i get the actual plans set up and accurate I would post a 3 view picture and suggest using scale and tile program or posterazor to get this plane in the air.
Until then i'll be working on the plans! Sorry but keep checking back!

Trust me, I understand the awareness of saving weight. Look at the little balsa plane in my blog. It weighs 18.1g w/ the battery and it's a biplane. I used hotglue to mount the motor. Used properly, hotglue can be extremely useful and lightweight.

Thanks. I build s...l...o...w...l...y, but they all get finished eventually. The modelers on these forums are great and my builds would be nowhere close to where they are without the help I've gotten here. I always focused on glue application the most. IMHO, it is the single most important thing that makes or breaks these small builds. I thought the same thing you do about hotglue and admittedly still bash it when my friend uses it on all of his foamy builds (half kidding, half serious). However, it can be useful if applied correctly.

BTW- I never commented on your build. I was blown away by your replica model of a model (). I've never had great success with foam and respect those that have.

Thanks again,
Kody

Hotglue should be heavy, but isn't
It's all about the application of it and why I mentioned the toothpick. I often use it to mount 2x4mm motors of planes around 6g and it does very well. Much like any other glue, sometimes anything more than a thin layer is just dead weight.

Alternatively, there's a type of double sided tape that people use to stick car license plates on with. If it's tough enough for that it may be useful. Can't remember the brand...will find out.

*edit* this is the sort of thing - http://solutions.3m.com/wps/portal/3...apes/VHB-Tape/
