Any questions on your build, let me know.

This mine with a scale head.

Very cool

Got out the bondo and sculpted some gear for Rex. Starting to look like a member of the chopper crew!

Finally got back into finishing up the mechanics this week. Just a few servo wires to secure and the tail will be all that’s left! I am using a brain2 FBL along with a Spektrum AR9030T and 3 sat rxs. One note is that I ended up spraying the top on the motor black using some high heat paint for grills. It is very visible from the top in the stock gold color and looks much more subtle when painted.

Also, while doing some research on the 36th RQS, I found out that they do training flights to get military dogs used to working in and around helicopters. Naturally, I couldn’t resist 3D printing a new member of the flight crew. Planning on putting a dog handler, pararescue specialist, and a crew chief in the back along with Rex. Stay tuned!

Good to know!

A few more quick notes getting back to the mechanics. The stock bearing blocks for the lowered tail driveshaft have the bearings free floating, and they can easily pop out if not secured properly. Some loctite 641 was used to secure these to the blocks. I also noticed a slight geometry issue with the aileron bellcranks from the Chaos 600. The Chaos horns are offset from 90 deg. This offset works perfect for the Chaos frames, but Roban frames for the Huey are designed for 90 deg bellcranks. I ended up using some Trex 600 spare bellcranks to achieve correct linkage geometry.

Just finished painting up my pilots today. Also added some decals for the unit patches and flags for some extra detail. Painting faces has never been my specialty, but I think them came out at least looking human this time LOL.

Thanks! I will get it printing on my next night off. Should be fun to paint.

[F106DeltaDart]

I have been thinking about printing that one as well. Did you have to enlarge or shrink him and how much? Thanks!

Yes, I scaled him down to about 65% of his original size.

Have been messing around with some 3D printed pilots for the Huey. Found the model on thingiverse, rescaled it, and it’s a perfect fit! Planning on printing another soon.

[F106DeltaDart]

Wow. That's actually lighter than I expected. I am assuming that is without batteries. Keep up the great work, and thanks for the info!

Yes, that is without battery. I'd assume another pound or so will be pretty close to the finished empty weight for the aircraft.

[F106DeltaDart]

Thank you. It doesn't need to be an exact figure. Just trying to figure out a ballpark weight.
Best wishes!

Right now, it’s weighing in at about 9.5 lbs. Thats all the airframe and electronics. I will likely still have to add a significant amount of nose ballast though, if my other Hueys have been any indication.

Sorry, didn't have a chance to grab it last night. Will try to get it tonight for you.

How much does this guy weigh without batteries? Just curious! Looking great. Keep up the good work.

Echo, I'll throw what I have on the scale tonight. At this point, its hard to judge since the mechanics aren't completely finished, and I haven't tried to balance the airframe yet.
