New Heli Build-Gaui X5 Formula

Post

I thought I would share my current heli project, a Gaui X5 Formula edition. It's specs are 1120mm main rotor diameter, 235 mm tail rotor diameter and a weight without battery of 1820 grams.

Cool! What are you using for electronics? Those hobbywing 100lv's with built in BEC would be perfect for it.

Hobbywing 100A platinum pro v3 esc, BK 7001hv on the cyclic's and a BK 7005hv on the tail. Scorpion 4020-890kv for the motor. The thing I'm most excited about is the Bavarian Demon 3SX fbl unit!!!

Nice setup! If you don't mind me asking, but why the Davarian Demon? I know they are waiting to release their next unit, but it doesn't have a gov. Its very strange why they haven't fully developed their3SX before bringing out a new unit. Also is it not normal to put a 4025 motor in it?

I was going to use an ikon but no one has had the in stock since December and I found out the demon has captain rescue. The stock motor is a 4020. I could run a 4025 but I read that it is a little power hungry and because of the formula canopy I'm really limited on running bigger than a 4000 mah battery.

Ok, makes sense although the IKON is now going for $150.00 and is back in stock. I can say that a 4025 is hungry compared to a 4020 in my Logo 550sx, but I'm running 4500's in it. I can get around 4 minutes slapping it fairly hard.

We need to see some of these devices to know what you guys are talking about!. Please let us know when you're going to fly, so we can come out and see these machines operate. Thanks,

Randy

Onward and Upward.

Last night I managed to get the frame assembled and I must say I'm impressed with the quality of parts in this kit although the manual could be better. I will post some pics after work tonight. I also have a trex 450 plus dfc with a scale airwolf fuselage that currently has a 3gxmr that I'm thinking about putting an ikon in.

Cool stuff whirly wing guys. Glad so see you on here with projects. The fixed wing folks have no idea what you are talking about. We need some education. 

Thermals---I need thermals!

Here's the kit and all the electronics laid out.

Last night I took the "pre-assembled" head apart and I'm glad I did, no loctite on the feathering shaft/spindle bolts!! That could have been ugly. Have to get a special driver to disassemble the tail rotor assembly but the build is still coming along. Torque tube was checked over and installed while carefully adjusting the gear 
mesh between the front bevel gears that are known to fail if too loose or to tight. I used the backing off of 3m double sided tape as my clearance gauge. I'm just about to the point of mounting servos and the other electronics.

Most mass produced kits are pre assembled, and have no loctite. I think it is because the thrust bearing stack is easy to mess up.

Is 3m tape what people recommend for spacing on backlash of those gears? I've heard notebook paper, but never 3m tape.

Ya the thrust bearings were in backwards as well. I use the printer paper trick for the motor pinion to main gear mesh but bevel gears need just a hair more clearance. I probably will have to readjust them once the gears break in a little before pinning the boom. Tonight I began the fun task of figuring out electronic's placement and wiring.

Scary thing about gear mesh is that you will know right away if its wrong. Either you'll break a few teeth off, or find a nice pile of saw dust in the canopy.

Nice thing about gaui frames is that every wire goes on the outside of frames, and no fishing wires around.

Post up more pics!
