The next logical step after my recent 6" build is to do a 7" build, right?

Going for something a bit more modern this time; F4 flight controller w/ OSD, BLHeli_32 ESCs, etc. on a less oldschool looking frame. Using the same 1900kV F80 on 4S as my 6". I'm not a fan of bottom mounted batteries, but the body simply isn't long enough for a GoPro & a big 2200mAh 4S both on the top plate.

Flight time?

cjdavies   Mar 10, 2019 

Easy 8 minutes on a 2200mAh 4S, landing around storage voltage.

I just finished my XL7 fitted the props and they hit the front standoffs! I have replaced the standoffs with thinner ones that do not have the larger diameter at the top and bottom that are supplied with the kit but even now the clearance is less than 1mm. Any flex in a prop and its going to hit the top plate with potentailly disasterous consequences.

Did you have the same issue?

I have replaced with straight standoffs but still not happy about the minute clearance, also if I hit some scraggle and a prop flexes upwards its going to hit the top plate.

I noticed that the XL7 now comes with 294mm not 284mm motor to motor so I have asked for my arms to be replaced with the new variant which no doubt has been modified due to this issue.

cjdavies   May 02, 2018 

I've built & flown many different frames with similar clearances & it's literally not once been an issue for me. Like I said, if a prop does bend upwards the tip will in fact curve further away from the standoff & the top plate.

I'm having the same problem. I first bought "Gemfan 7042 Flash Propeller 7x4.2" and while they don't touch the standoffs, the clearance is less than a millimetre. As soon as I take off, I can hear them touching the top plate because that's a few millimetres wider and the props are flexing up. Once I move them by hand I see where they touch. I was hoping that other props would work and these did: "HQ Durable Prop 7035 7X3.5X3V1S". They are just that 0.3 mm shorter. Still the situation is a bit anoying. BlueFish, if you found a solution or want to exchange ideas, let me know.

Love the build! What are the blue props?

cjdavies   May 22, 2018 

Gemfan Flash 7042.

Have you thought about putting GPS on it?

cjdavies   Mar 28, 2018 

Nope, I don't do any long distance.

Jodie Froster   Feb 02, 2018  

So tidy and thorough!

cjdavies   Feb 02, 2018 

Thanks! It's not my best work, but I found it surprisingly cramped considering it's a 7" frame! Guess I'm just not used to building with 28mm standoffs.

Jodie Froster   Feb 02, 2018 

I was suprised when I saw all the mounting on the top plate. 7" frame isn't really any bigger than a 220 from the looks of it.

cjdavies   Feb 02, 2018 

The actual body is substantially smaller than my 6" Armattan F1, but I guess the size of the body doesn't have to follow the size of the arms - you could have a 7" pod build with less space in the middle than a 5" Alien clone.

RZFPV   Feb 01, 2018  

what size cap is that

cjdavies   Feb 02, 2018 

2200uF, it came with the Typhoon32.

A couple years ago I built the TransTEC Frog and since then I've been patiently waiting for another TransTEC frame to catch my eye. Fast forward to today and the TransTEC Laser S is that frame. It's a 82g racing frame that features 6mm arms, a TPU micro cam mount, 30.5mm and 20mm stack mounts and 3K carbon and 7075 hardware. My goal here was to build a high quality 6S racer at a reasonable price. I'd..

This is the 4th installment to my popular "Wizard Killer" series, and is based on the popular Wizard X220HV 6S. As usual, the goal was to build a substantially better quad, yet come in below the retail price of the BNF kit.
