So there are issues going on. Not even sure if I have the updated components inside per the item description. Got the email regarding the battery and created a ticket. Haven’t heard back.

That's not what I got on my UH-1 i got the older Blue 6s one. What KV is your Motor? I sure hope it's more than 1800. I had to remove my motor bolts and the four screws holding the motor mount in place as-well the four screws holding the frame to the fuselage just to get the motor so I could see the KV.

Its the motor listed in the specs. 450L-1800kV Brushless Motor. I removed the 4 bolts from the bottom and slid a thin mirror under the frame to look.
To go 4s it should have a much higher KV. I’ll be curious to hear your flight results.

IMO You might want to contact motion about that. Not sure if that is going to work. That put the head speed at 2400rpms with only 10% headroom. When I flew mine at almost the same rpms 60% throttle in 6s I had LTE really bad.

That’s the stuff I used for the mod. For 4S, you might at least be able to go to a higher tooth count pinion. That would buy a bit more headspeed. Haven’t had the chance to try mine on 4S yet, but it’s on the list at some point.
thanks again for the heads up.

Had the chance to take up the Huey on a 4S 2200 this afternoon and it flew great! Bumped up my throttle curve a bit and had no LTE issues. Even tried down some pretty fast sideward flight in both directions without any blow outs. I think most of the LTE issues came from the high pushrod friction.

That is great to hear. Obviously the 4s 2200 fit ok, CG wise and added weight. How was the temp of the battery after the flight?

Guys you haven’t, do the tail mod F106DeltaDart did. It made all the difference in the world. My tail gain is right where all my 450 microbeasts are at now. Between 27 and 30 and rock solid. Also now that my tail is under control I can see it working on 4s as I tried it at 50% throttle on 6s and I hand good tail control.
im going to get a talon 60 before I put it all back in
I also made some shims so when I put her back into the fuse it will sit level instead of leaning to the left.
she’s going to be a sweet flier.

Removed the mechanics from the fuse today and adjusted the belt tension. Now it rotates a lot better. Installed the Microbeast and took it for a test flight. Major tail wag. Going to mod the linkage per the suggestion and see what happens. Talon 60 on order as well. Note: CHECK ALL SCREWS! A ton were loose and without thread lock. Thats why I asked a few days ago if these are flown at the factory as stated by MRC.
Anyone know the correct programming rates for the servos? Can't seem to find that info. Thanks

Well tomorrow I’ll giver her a good shake down.
got my Talon60 today and installed it. My rpms are 1500 for ideal up and 2300 for flight. Did a test hover outside of fuse and all was good. Put her back in and buttoned it up. Did a test hover then in the fuse. Sounds like some fuse vibration. I might add something to lock the frame in, in the dog house. We’ll see after I put her through a good flight.
ill report back tomorrow.
