4215's are not the kde equivalent to the U7. Not a chance. I learned this the hard way. If you don't mind running a motor @ 250F to get that 3kg of thrust than fill your boots. Patrick put out a video regarding various temps limits of his motors components. I am not Patrick so I can...

I don't think the lens is gonna help. Let's do some math here. You have 4kg's just in batteries. 2.5kg for camera (no lens) 2.5kg for gimbal (no battery) You are basically at your max weight without even considering things like the aircraft itself. Lol. Motors, electronics...

I think you are way under powered. Other guys are hinting at that but I figure no point in beating around the bush. If I trusted KDE data to be accurate, 1310 grams per motor @ 50% brings you to a safe AUW of about 10kg. MAX I suspect you are way over that.

I didn't mean to post misleading info. I was told by a few people about her trying to move to home point immediately after takeoff. I just believed ot to be true. I blamed it for a tip over I had. Lol

This is a prime example of when to take off in atti. gps home point could change by 30' from when you arm the motors to when you actually take off. The craft wants to immediately fly to the home point = tip over.

what gimbal are you using? $350 for a quick release is not chump change.

Ya. I have since changed my train of thought. I'm probably gonna get the armatten cf 355 frame (bullet proof). Same size as a phantom. Naza lite (flash to v2) And the tmotor kit air 350.

Lol. I knew that. Was just pointing out what the real flaw is. If they left that corner square, it would never break.

It's not the metal they use. They machine a dumb ogee on the corner of the cylinder making it really thin. For cosmetics I guess.

My p2 is officially retired. Over 600 miles, 250 flights, 3 shells. Many, many crashes. For the last 6 months I've been using it just as a trainer. No gimbal or camera. Now it is at the point where it is not cost effective to get her up to snuff. So I want to build a 250 sized racer...

The replacement part is a brand new retract. Lol

24-25c

I leave camera osd on. I missed a really good shot before because I forgot to press record and the camera osd was off. At least now I can tell that it is recording.

110-120 The heat sink mod is giving me about 20 degrees cooler.

I bought the lites for load testing and my original trials. Far better to break them than the tmotors. I use the tmotor washers on top of the props. See pic attached. Forget about the hub balancing. Try getting these centered properly. Impossible. The kde ones were worse because...

They all have quick release prop adapters so that's how I weighed them. Tmotor is 2 grams less. My scale doesn't read in tenths.

I decided to do a little bench test on 2 brands of 16" props. Tmotor CF 16x5.4 props are about $45 each and have a double wall style of airfoil with a cork core. Foxtech Supreme Lite CF 16x5.5 props are no longer sold but they were about 1/3rd the price as tmotor and have a single wall style...

I am using the @Hexacrafter vibration isolation system. 4 x blue and 4 x red balls.

I'm gonna build a 210-250 sized quad. I plan on trying the air 15's. I don't need bec's because I will used the naze and the OSDodg.
