Miss that distinctive 'whop whop' of the blade. After 50 years I can still tell a Huey from a Chinook or a LOH (Hughes 500 Light Observ Helo) flying overhead. Sometimes I miss those days flying fast and low over the canopy to avoid taking fire (still got me with some shrapnel from an AK on the ground).
I am seriously considering ordering this Huey so I have been reading the posts but have not come across any RC pilots who have commented on how sensitive the collective and rotor pitch controls are to fly for an advanced novice. I have flown 4 ch winged and 6 ch (dual rotor) so this would be my first venture into using a collective (other than my real-world crew training landing & auto-rotating). If one of you stick jockeys would be so kind as to describe this old geezer would be most grateful. Please include which transmitter you prefer so I don't make an expensive mistake.

Hi everyone. I have just signed up because I need some advice. In the sales advert, the recommended battery for this helicopter is stated as 4S 14.8v. 1600 - 2200mAh 30C but at the start of this forum, it seems to recommend a 6S 22.2v. 1100 - 1500 30C. Now I am not new to helicopters using engines but electrics are a dark art to me! I do have a couple of electric sports planes but followed the manufacturer's recommendations and have had no problems so far. Are either of these batteries compatible as they have 2 different voltages? Also, I am using a 4S 14.8v. 4250mAh 35C battery in one of my planes, so can I use it in this helicopter? Thank you.

Hi, I am fairly new to Scale Helicopters. Been flying scale aircraft for a number of years along with Pod/Boom Helicopters. Thought I would branch out to scale helicopters and just order a 450 size UH-1 Huey from Motion RC. Was wondering with the 3DPUP files are still available and if there are other ones beside the ones pictured here?

This Roban UH1 "Super Combo Kit" I purchased from MotionRC is the gift that keeps on giving and keeps on siphoning money from my pocket.
This kludge excuse of a kit is a joke. This will be the last thing I purchase from MotionRC. MotionRC/Roban basically grabbed a bunch of mismatched leftovers from their dusty shelf and threw it in a box and called it a kit. Silly me! Also silly others who actually believed this joke would assemble and fly out of the box and who ended up crashing their UH1 because they didn't setup on a test jig first and get the heli flying before placing it into the fiberglass shell. $1000 here, $1000 there, it's only money. I should say it's only the customer's money since MotionRC won't do squat after their 30 day fogettaboutit support policy.
Quick summary of some of the earlier problems...
1. Received mishmash of 47 mm and 54 mm parts for a 54mm frame. I was then sent a couple of spacers the were wrong size. How difficult is it to subtract the difference and take that missing 7mm and divide it into two 3.5mm spacers? I also ended up buying over $200 of parts that were either wrong or missing. Some parts of the kludge design don't even exist... i.e. be ready to machine your own parts such as the correct 3.5mm spacers and a self lubricating bushing for the tail drive shaft. I could go on but you should get my drift by now.
Now on to the latest problem.... Apparently the MotionRC/Roban knockoff/counterfeit thrust bearings are total trash! Weird thing about thrust bearings is that they can feel just fine but when you fly them they basically try to lock up and create a slow tail wag that NO controller can deal with. I also decided to get the Align "Red" upgraded tail bevel gears. Ed Ardriano at MotionRC told me that the crap gears that were originally sent to me would shear in seconds of the first flight.
No big deal I just threw another $125 at it today and ordered "GENUINE Align parts to replace the entire tail assembly. Here's a short video that you can skip through for your viewing pleasure: https://www.youtube.com/watch?v=4AaIVuzTDds

Originally posted by Alpha View PostIn time for Independence Day, here are some updated 3DPUP .STL files for the UH-1. With a few hours of printing and basic painting/cutting/screwing/soldering, one can really personalize the model beyond what arrives in the box. I especially like the fiberglass body because typical techniques from the plastic modeling world can be used. I haven't had the time to take this model to the next level, but it's nice knowing I could. Work in progress...
Stance: Cut the struts down the lower the stance as shown below. For more scale, shorten the skids themselves. I haven't done this yet on mine.
3DPUPs: The files attached for the most part screw together. You'll need lots of 1.5mm wide screws.
Ammo belt: The great thing about PLA is that it softens under heat. A half second pass over a lighter will soften areas enough to bend the strip before it hardens again.
Drill 2mm holes into the fiberglass, and use those holes to also drill through the holes of clear green sheet. I try to minimize where glue is used.
I'm new to this hobby and just ordered a 450 Huey that I certainly will want to personalize when it arrives.
What type of 1,5mm screws are you referring to?
I've googled around a bit but it didn’t make me any wiser.
Will M1.6 6mm cylinder screws work (as per the link)?
If not, what exactly do I need?

Am I missing something in my search?

Good day,
I just bought this second hand, it was never flown by the previous owner (or at least so he claims) and I have received it without a decal sheet or the horizontal tail fins, he claims it never came with the heli.
Where can I get these? The decals are out of stock on your website and the tail fins are not available at all?
Are you going to stock parts for this at all?

So I tried to tighten them up, but they wouldn't budge. Anyway, I ended up stripping them so I just ordered a replacement head from eBay a few weeks ago. Still waiting for it to arrive
