Answer: 291 grams with 637mm lenght (TT ready to install)

I understand. My concern is my eyes in my case as product is corrosive.. Protection is recommended anyway. I'm wearing nitrile gloves, hermetic googles (to vent time to time once fog starts to develop) and working in ventilated room. I also avoid watching closely the parts without protection when...

UHU Plus Endfest 300 here. I like its properties and goes where I want with setting the position of the assembly (gravity). I also use it as filler and sand it after 24h. Ex. misplaced hole: fill it and drill again. Sits very well in deep areas and air bubbles are evacuated on the top (very...

Super clean setup !

Awesome work indeed 👍 Pilot seating well ?

In addition to the programming logic, I use: 1. Labels 2. Colors (shrink tube, I don't like the usual caps as too thick for me) 3. My innovant mechanical protection, same idea as real aicrafts switch covers, so I don't shutdown the turbine inadvertently. The 2nd switch with home made arm tells the...

4/4 - Done

3/4

2/4 Nylon self locking nut recommended ..

Ok doing now. Again, these are just suggestions, take it as check-list 😊

Thanks, all good re yours comments. I also tried to open same image but no success, possibly web site issue with its size. Maybe Mike will pass by and the check the same. Otherwise I can post the images individually, just let me know if interested.

Thanks for sharing ! Find few ideas of things to check, mainly for reliability purpose. Possibly also of interest for others passing by. Great job by the way!

Yes, topside connection is key to avoid fiddly oscillations. Without using a camera, one can only see tail movements without noticing that's coming from the head. I also use a camera inside the cockpit to monitor vibrations and eventual degradation over time of the components, like real airliners...

Great pro work Danny !

Never seen indeed, either build reports or Vario wiki (I won the 2nd prize in 2023 contest with Bell 212 1:7 build report). Usage of video projector looks to be generally "undocumented" or not used often, while makes so sense to use it for best scale results, like a laser. Maybe I miss something,...

Using the video projector is brilliant, never seen this!

Given the size of such heli, the manufacturer of your rotor head could propose a "lifting eye" part, which is temporary installed for lifting operation (screwed in for AS350).

Thanks for sharing. Interesting re more prone to resonance when using more than two blades. Must admit that's counter-intuitive to take off asap when resonance starts to happen. The "ground resonance" incident in MacGyver occurs in the episode "Deathlock" (Season 1, Episode 12), where a helicopter...

Hats off, Patrick. Wonder if same device could have a variant dedicated to non-air vehicule, like a tank with dedicated effect. Well done!

I use the pitch curve as last optimization step and tuning for 2 main things - max 3-4 points: - flaten the curve on the hover zone to create some cushion - temporary compensate hot weather/lack of density by increasing the pitch on the mid upper range (I do on 2nd flight, difference is impressive)...

Good way to smoothly extract a bearing while appyling enough torque. Align has a tool based on same concept. I use it when fits with bearing size.

It's an Amewi AMXRock RCX8B Scale Pick-Up 1:8 RTR. Very good quality for the price. Added few options from other brands: - Alu hook, shrinked to fit within chassis - 2 additional rear schock absorbers (now 4) - White leds inside headlights (no lights at all for the version I have received) + gyro...

Same here. Make sure to unplug its blue battery if not used for long period (Ultra Guard does ongoing monitor = little consumption). I use also the BEC Guard and led flashing module of same brand as full protection combo.

An idea would be to have a window for inspection/service, similar to Baumann (carbon cap). Per exemple on below side so we can access without removing it from the tail. Would love to have if not too heavy and same dimensions so replacement of plastic one is possible.

Motion including arms is awesome, I find it realistic. Must be very visible in flight. Well done!

The good thing with this hobby is that we got some flexibility on choices and there are options on solutions!

Same here. Further changed hub + blade holders to Vario for bigger ball bearings. My choice, Baumann products are fine and professional service. Notes: - don't fill full of grease, not necessary (surplus will exit between shaft and bearing anyway). - grease V10/360 here. - open the little window...

Tip: I use a 4K camera + onboard Insta360 to analyze vibration status at ground and in flight, and zooming with video editing software (some patterns are not necessarily detected by FBL unit vibration detection feature). Also, whole fuselage must be sharp when scrutiny pictures taken with 200mm...

What I have done for my Lama is simply to add two tiny wires in parallel (not in serie as usually) to snif the current voltage and this is connected to the external telemetry voltage input of the 7008SB. At some pre-defined low voltage I know it's time to land and there is approx. 20% battery left...

Your setup should tell the possible options and their size. Tell us more! For my Lama Vario T-Rex I got Emcotec 100/200 and three OptiPower modules: Backup + Flash Alert + Anti EMF/Power back. Switch is convenient to connect the batteries in advance with no fiddling of the heli at public show.

One tip for such piece is NOT to be air tight: internal pressure must ideally equalize with ambiant. All depends how mounted, rigidity, volume and internal struts if any. Mines started to inflate after returning from a meeting located at different altitude. Drill a tiny hole afterwards, if needed...

Remember that red wiring can be very visible! (your gears will be out sometime)

Hi Danny, no answer yet so jumping in. Ask to Vario if not alrewady done - Exhaust area vs fuse shape can be the problem. Remember also that the 3-3 has a much rear CG so possibly more weight to add in the nose (we would fly this model quite sporty so best to be light) Keep us posted please!

Amazing how rpm of AC is stable despite high rotation, see btw -0:55 and -0:30. Smooth pilot inputs, great AC setup and ECU management.

Maybe your dog should be more involved 🤣

Cable lacing is well used in aerospace. Find very interesting article:

I use a lot these, they are very handy to install also afterwards as we can open them. Material is not just basic plastic and is heat resistant. I use a lighter to stabilize the tips when I cut them. Excellent product.

The speed of the retracts is very close to the real one, around 4-5secs. Great!

Thanks Butch for your time, much appreciated. Another factor is maybe on which side is the AC. Mine is CCW with Baumann AC metal gearbox on the right side (spinning CCW) = also more weight on the right! Done this as I wanted to have it same side as the real, contrary to build manual.. This setup...

Very nice! The fuse looks calm and neutral which is great news. Can see little tendency to find its horizon slighty tilted on the left. Don't think its related to wind as doing this in different situations during whole flight. Have you noticed the same? I would eventually revisit main shaft angle...

Super!

Mmh I'm not convinced about skin tone and the lips are very contrasting. Find comparison. Truck driver is 30$ Ken toy, just to avoid an empty cabin. Pilot is a much more expensive pilot, on which I've done some weathering to avoid plastic looking (quite ok from far). Of course, there are much more...

Status update after one year+ of experience since my last post: Header tank is a MUST, even if your setup is presumably dealing well with bubbles, thanks to felt clunk, flexible movements of clunck, cone below the tank (look the picture, there is a black cone below the fuselage), etc. Bubbles do...

Tom Cruise should watch this awesome trailer 🎬

Mike knows Roban very well, check out he´s YT channel if not already done, example:

Gustave Eiffel would have loved this engineering 😄

Hi Uwe, suggest we compare our settings because your camera should follow heli angle, not counteract and keep horizon while you turn - this is not realistic! For the high freq vibrations there is also something to explore. . You can send me a pm if you want!

Hi Uwe, here is my home made adapter, as you requested. Took some time to keep it simple and find ideal dampening so the software can best process accordingly - see settings below. From the top: - fir wood glued to fuselage - thin carbon plate cut from small heli battery tray - dampeners and plate...

Notice the angle on the stabs done by Uwe. Awesome details all over the place!

See how I do my cuts: - no rush, have a progressive approach, no direct cut - I use car deco strip to define e.g., how large is a border of a window - apply car deco stripe for marking exact cut - protect all around, see bottom left picture - use Dremel "right angle adapter" (option to buy); helps...

To check a standard led individually, I connect it directly to a CR2032 3 Volts button battery, making sure polarity is correct; the longer leg of the led is the plus (+). If the leg is already soldered to a lead, then the red one is likely to be the plus. A led can be standard in terms of voltage...

Note regarding the main gear upgrade: Roban issued a new improved version following customer feedback, ref. SHSM-800SU. About this main gear replacement, see e.g., YT channel "Northwest Scaleworks by JestRR" and look for video "Roban Reach Bell 407 Re-Gear and spring tuneup!!". This is maintenance,...

Don't worry about the hole, metal is very robust.

Same here, I have imported many of them from Korea (from manufacturer). See their website for size and lenght. Exchanged couple emails with them (in english) and worked great.

Butch, out of curiosity you installed the retracts without cutting the windows to ensure that the fuse keeps the shape or any other reason?

Was great to meet you Uwe -Fantastic work 👍

Check out your telemetry log at 2min20 to see if it was you doing backward cycling input to counteract sudden acceleration (heli was happy to accelerate given axis and maybe the air going same direction)

Someone noticed that I was systemically doing CCW circles. As valid comment, I practiced more CW's which I didn't find obvious dues to the ´bad' habit .. Something I will never forget.

Tip: I use my kitchen marble to verify if the TT is straight, looking for any light passing below. Very acurate. If absolutely wanted and no replacement part available, little corrections can be eventually made with bending gently manually, with practice, lot of patience and time .. as well accept...

Excellent! Maybe some extra weathering for extra realism but this is already master piece and difficult to tell if real .. or real 😄
