FT EDGE 120%

[Folgore88]

Hi guys,
after FT spear which I enjoyed a lot, I decided to build FT Edge 120%. I have just printed the plans and in these days I will start to cut the raw depron. I have a Brusheless motor Prodrive 2836 1800KV left over from other models, ESC 50A, lipo 4200 4S and 8x4 propeller. What do you think I can use this setup ?
Any suggestions for building FT Edge 120% ?

 

[Dean is the name]

whenever you're up-scaling something you should think about extra reinforcement because the bigger you make it the weaker it gets.

Thank you Dean, yes it is true. Tomorrow I'll start cutting and step by step I evaluate the reinforcements. I also have to check all the parts that must not change with the upscaling, e.g. Servos holes etc...

An 8 inch prop is a tad small for the Edge, especially at 180% 120% (edit: typo 8 for 2) . It'll probably fly fine, but if you're planning for low-speed 3D maneuvering then large props will give better throttle response - the stock edge uses a 9 or 10x4.5 depending on cell count.

Thank you Pieliker96, I made only 20% upscaling
The suggested propeller is 6x4 battery 4s, maybe with a 9 or 10 inch propeller the motor gets very hot.
This is my first aerobatic plane. I would like FT edge flies well even if it can't do low speed advanced 3D, I am a newbie.

There isn’t very much prop clearance on the edge with a 9” prop. I doubt an 8” prop will clear the cowling at 120%.

Thanks for your advice.
I have seen your posts about the Edge 140% very interesting. But then did you build it and fly it?
According to the engine specs with 4s battery they recommend propellers of maximum 6x4. So, that was my doubt, I will buy a new motor, according to your experience what do you suggest for my 120%?

Unfortunately I haven’t gotten a chance to finish mine yet, I wasn’t able to make it past the cutting stage, it’s just so much to cut out. As far as a motor goes, this one should be perfect:

The ft edge plans recommends 9x4.5 prop on 4s, 10x4.5 on 3s, not sure where you are getting 6x4, a 6x4 would barely (if at all) clear the cowl. I would not go smaller than a 12 inch prop at 120%.

Ah, I see, I was confused.

Good morning from Europe, I've been cutting raw depron for two days and I really understand what didn't inspire you to continue with the Edge 140% project and especially starting from scratch there's a lot of work to do, but that's also the pleasure. I hope you can one day finish your Edge 140% and let me know how it flies. Thanks for the motor recommendation, I'm looking to buy a new one. Thanks to all
