For anyone else who wants to know this answer as they try to plan out their purchases, I have found out today that a 3 position toggle is not mandatory if you dont mind setting the mode (Normal/Auto/Learn) via Telemetry with a Laptop/PC.

Moving forward with my build, I will be keeping the DX5e an setting the 2 position toggle with Normal an Auto.  I will set the APM into learn mode via my PC when needed.

Next weekends plan will be to get the new Receiver installed an purchase the APM 2.5 w/Telemetry kit as well as a FPV setup.  Then start planning the install on my Crawler which is a Axial SCX10 Jeep Rubicon.

Question for the people in this group.  Is there any other method to set Normal/Auto/Lean on APM 2.5 other than via a 3 position toggle on the transmitter?  Has anyone developed a switch to be directly attached to the APM, or can APM mode be set over Telemetry?  This is the last piece of information I am trying to locate to decide how I want to build my Rover.


I bought a decent entry level 5 channel transmitter (DX5e) which only has a 2 position switch an a momentary toggle.  In order to get a transmitter with a 3 position, I would have down grade the quality of the transmitter.

Just joined the group. K5BMA here in Hawkins, TX.

I.m in the process of building an APM 2.5-based quad with 915MHz telemetry and 5.8GHz video. Right now I'm using a Hobby King KK 2.0 flight controller to learn proper control. I used to fly RC helicopters in the early to mid 90's using a Futaba 9ZHP on 6 meters; still have that bad boy but put a 2.4GHz spread spectrum transmitter in it; I like the smaller antennas and the true diversity receiver.

That's all for now.

Bret, I've been considering doing something like that for Field Day, but haven't gotten as far as completing the drone yet.

Building my first drone (rover) based on a APM 2.5 w/Telemetry (915Mhz).

Any hams put up a drone circling containing a cross-band repeater for field day?  Bret AC0AE

I have not seen it mentioned yet but have you fellow hams noticed the 3DR Ground Control station and those that have added Alt/Elev tracking using it?

KD5ZZL Here.. just checking in.  I have a couple of Quads, still tuning the second one, (3DR Arducopter) .

I have the 3DR 915 MHZ telemetry system, and I love using it with the Mission Planner. It has a stated range of a mile (100mw with a whip), I think the furthest I have been out is 1/2 mile.

The 915MHZ system range could be extended dramatically I bet with better antenna's and bi directional amplifiers, and a tracking ground station antenna. With what I am doing right now, it is working fine with the included whip antennas

I do hope to move to a longer range system for all rf components, video, RC control and telemetry.I have some tiny trackers somewhere and a small low power 2 meter handy talkie I might mount on my quad so I can put an APRS presence on the map..

73, kd5zzl

Anyway just beginning to scratch the surface of what can be done and loving every minute of it.
