Hello Cletus, the flying weight is 18.7lbs (8.5kg) with the 3 batteries, 2x5000 6S, that i use for everything (motor, servos, received, etc), and 1x1,500 3S that is use for the lights system.
Head speed 1,250rpm, i tried to lower it to the 1,100 suggested but at 1,250 it feel more comfortable, for me, in the way the heli respond. Fly time 8min but the batteries still have 55-60% charge after landing. I hope this help you with your project.

I had the pleasure of working on this fantastic machine.

The client wanted me to tweak the radio and FBL to thier personal needs. I also went over everything from top to bottom, channel to switch, nip to tip. This weekend we will begin flights and settings.

When i say im going to do a job i do it right or i dont do it at all.

I have to say they built an amazing model!!!

Hello there. I just signed up for this group and wanted to introduce myself. I'm trying to learn everything I can about flying RC Helis and someone from a FB heli group suggested to sign up here.

So far the only Heli I've been able to fly consistently without crashing is my T15. My Oxy4 has been a significant challenge in the whole setup process with the FBL system and settings in the...

Hi all, I have a Roban Bell 407 700 size just recently completed. I'm running 12 degrees positive pitch and about 3 degrees negative. This seems fine on all my other scale ships but this one seems to not want to rise sort of speak. If I'm hovering stationary and go full collective the model goes up very very slowly. I'm afraid to fly it thinking it may sink to the ground when I come back to a...

verify head speed. The 700/800 size Roban should be around 1200-1300 I would not recommend anything over 1300. -3 and positive 12 is right on the money. What is the pitch at mid stick? Also what FBL are you running? Are you running a pitch curve?

There are never by-the-book settings. You should start with your throttle (determine whether you want idle and full or a curve) and then move to your desired high and low pitch angles. We will be creating a course on this that will work with any capable transmitter
