Build Log
TB EDF Ultra Viper 85" Wingspan Build Thread (from EDFHobbies.com)

Going to do a build log on this jet...

it does change the game some when it comes to large edf power, size, price... etc... so I think its note worthy ....

EDFHobbies is having a contest on some of the stats of the jet so I'm not going to post everything about the power system (which you can guess which one it is easy), weight.. etc etc..

Goes together easy... just take your assembly skills from the rest of the jets you've built and apply here.

Didn't like the hardware (who ever does?) so swapped that out ... here are some pics to get things started... all metal flat wing servos are from EDFH... good price... beats hobby king

Here are the pics of the elevator servo install

Back to front assembly

Got elevator servos from EDFH also... decent price and true "getting it out the door" toughness ...

The control horns that came with the kit are ok... decided to use em

The retracts were small... wont do grass well so I'm being sent some of the retracts from the Super Viper... They're bigger than what was flown even though those retracts REALLY held up well...

In the first video I plopped the model down pretty hard on one gear... the thin CA help up well enough

Also, there's going to be a straight strut retract option with brakes... this thing will need em.... it floats long time

Hopefully the stance will be similar to SM Viper with taller tougher gear

Model needs to be taller IMHO...

It also comes with inner gear doors... and FLG door... I was too impatient to fly so I didn't put mine on...

So 3/16" struts if wire or if Robart struts, 7/16" should hold well.
Whats the expected all up weight projected to be?
Already have a reply back from EDFH and an invoice with tracking number!!!! Said expect them in to EDFH within the week !!

OK, so the weight and watts will be kept secret as is on you the EDFH website. Is this the same size and build as a Skymaster Viper that i have seen other videos of with 120mm setups? If this is, then plenty of useful info can be gained and possibly applied to this plane.

I stand corrected on sizes!
Skymaster is ws 2600mm x 2400 lng
JTM Viper is ws 1840mm x 1700mm lng
EDFH is ws 2100mm x 1840mm lng

Sounds great that i may have a use for my ETurbax now. I was thinking that SM had one but i second guessed myself thinking of the JTM one. Again plenty of info that could be applied to this size of airframe.
Any chance for pics of the inside and some equipment layout...........without giving away the secret?
