r/RCHeli

I posted in this sub about a week ago asking for recommendations on where to get an rc heli, and I chose motion rc. I LOVE my huey!! it is such a great heli and I did break it on my first flight, but it was an easy fix. It was pretty windy last evening, but that didn’t stop me from flying for almost 2 hours and I ran down the battery lol. After work I am definitely flying again, and im taking it on my trip next week. I wish I could add a gimbal to fpv it, but it might be a bit too heavy.

looking to join this hobby and found this used Hirobo .46 Nitro Engine GPH 346 RC helicopter for my first heli which seemed pretty good for the price. Does this heli look like its in good condition/maintained well?

I have experience with nitro rc cars tho.

Seller description: Futaba servos and Gyro, also comes an extra tall boom, new spare tail rotor blades, new belt conversion kit, 2 set of new main rotor blades, one set of carbon fiber blades, some small extra spare parts and original building manual. Just need to plug in your receiver, recalibrate everything, connect to your own 8ch transmitter and ready to fly.

I love the MD 500. My favorite helicopter ever. When this RTF version became available, it was a must-have. It looks 95% scale right out the box. The extra 4 in makes me happy. (That's what she said).

I was able to do a handful of successful flights. Cannot wait to get to the airfield this weekend. 

The tale boom extension was printed in lightweight PLA, reinforced with carbon fiber rods and held on by epoxy resin.

I added a dollar worth of coins to the nose, and push the battery all the way forward. It flies good so far it has been super windy and I get home late so haven't been able to get any great photos, stay tuned.

Recently bought an OMP M1 V3 Pro to be able to practice at home. I still don't feel comfortable doing complete flights backwards. When should I try inverted flight?

Greetings all,

Last year I got a SAB 520 and had a ton of problems with the tail belt rubbing against the main gear and pulley. SAB was no help at all. I spoke to Amain Hobbies about all this, and they gave me a very good deal on a new 520 kit. I built the new kit without using ANY parts from the original kit. It seemed to go together just fine and the belt looked good, thought I knew it wasn't perfectly riding along the pulley. This was in November of 2025.

Now it's May 2026 and the belt on the new kit is starting to show real wear. These belts should last for YEARS. I am now wondering what I can possibly do to keep this thing from requiring a new tail belt (and possibly more parts) every 6 months.

I could really use some suggestions here.

Just received the MD500 Magnum PI design edition from Rodan. 

This fuselage is beautiful. The lighting accessory kit is amazing. 

The only trouble I've been having so far is with the telemetry. The voltage indicator on the helicopter is always at half full even though the batteries 100% 

I'm thinking this is causing premature return to home triggers. 

If anybody has an idea on how to recalibrate this setting please let me know. 

The other issue I had is with the tail it's not proportional to the size of the helicopter. If you look out there other bigger models all of the tails are longer. 

I have disassembled the stock model tail mount. 

I am currently designing and 3D printing and extension motor mount that makes the fuselage look more to scale. 

Hear a few prototypes so far. 

Going to be using lightweight PLA reinforced with two part epoxy resin and then painted.

I had to extend the brushless motor wires and the rear beacon light wires.

I took the mechanics out of an RC-Era C-189, and forced them into a printed CH 53. The CH 53 was intended to be a desktop toy, so I had to scale it up and modify it the best I could in my slicer. Not a lot of editing options in a slicer.

Anyway it flies, but barely gets off the ground 😂. I printed the body as lightweight as possible, but the mechanics just don't have enough ass to lift this bad boy. I ordered some blades from a YX F-119S, to see if I can adapt them, and also a four blade tail from a Goosky E2.

I think it will fly better with those adjustments, until the motor cooks-off 😂. I will report when I get them adapted.

Hi Guys,

im facing some issues with my omphobby m4.

Dont go hard on me, im new to "bigger helis". I've only flown M1 and M2 before.

on faster collective inputs like a flip or tik-tok my heli tail starts wandering out. Also the whole heli kind of knicks itself inward and is generally wobbling around. Hard to describe, i hope you can see it in the video.

I tried playing around with pitch precomp and tail gain settings - no success

PID on Ail, Ele and Rud did not change much from Jonas settings.

When changing from ~2.1k RPM to 2.6k RPM, it gets much more stable.

I put much efford into the build and double checked everything. (it was my first build tho)

Remote: Radiomaster TX15s with ELRS
FBL: MSH Brain 2
PID Settings i use those from Jonas Wackershauser slightly tuned to the current 2.2k rpm

Maybe a heli god has an instant answer to this. Thanks!

Orientation practice in the garden 😊

Hello! This is the motionrc OH-58C that I am in the process of converting to a D model. I have two issues. One is making it have 4 blades. The other is adding the clay MMS without making it spin with the blades. I’m still very new to RC helicopter modifying, so please bear with me.

Question 1: How would supergluing those two other blades on the top affect the flying? I’m too inexperienced to connect them to the mechanics of the helo.

Question 2: without too much equipment or knowledge, how would I make my mast-mounted sensor not spin with the rotor system?

Thank you for your help!

The weather's good, the grass is growing, and I'm itching to learn to fly upside down. After a lot of crashing I'm starting to get the right feeling for the collective and flipping upside down is getting easier. The aforementioned tall grass is working hard as a cushion too, and possibly a mental cushion. It was extremely gusty today, but in a calm period I was able to sustain my hover onehanded long enough to snap a picture. When gusty though the heli really dances and bounces around.

additional picture: replaced feathering shaft since my original one was bent since forever. Used loctite on the screws. Strong as can be!
