My ft-3D was a no trim maiden! I trimmed it out on the ground and made sure everything was perfectly straight and she’s tracked like an arrow upon launch. 🙂
Ugly 3D - what the heck is this?

Well guys, I finished up the adjustments and have this ugly thing ready for another go. I wasn't able to adjust the motor mount to give down thrust like I thought it would, so I put a couple washers between it and the firewall to tilt the whole thing down. And I finished peeling the covering off the winglets and hit them with a coat of bright purple paint to keep it looking "stock" 
Here she is hanging from light cords over the garage door rails. If I ever want to use the garage door again it will take me days to move everything

LOL. Looking good in purple.Well guys, I finished up the adjustments and have this ugly thing ready for another go.

Update: I took her out for a couple flights back in March, and doinked her in pretty hard on a landing, tearing out the landing gear bolts. I repaired that and she hung in the workshop until yesterday when I took her out flying again. When I started to taxi out into the runway, it started to make a loud rattling sound when throttling up, and then the whole motor bell and prop flew off!
Close examination showed the motor shaft broke at the rear c-clip which I've never seen before! Must have been damage from the landing / nose over that took out the landing gear. The bearings aren't running straight anymore either, and the motor grinds badly when I try to spin it, so this one is going to be dismantled for hatch magnets.
Time to search for another cheap motor that will swing a 12x6 prop around 1450kv on 3 cells... anyone have a favorite to suggest?

You sure you don't want to go 4-cell? I'm a big fan of the NTM propdrive motors. They have a 3542 1250KV.

I use this: https://rcplanes.online/calc_motor.htm
According to that, you probably want an 11x5.5 on 3s. On 4s, a 10x5.
Personally I'd go for a 3548 because #mopowababy (https://hobbyking.com/en_us/propdri...981&indexName=hbk_live_magento_en_us_products). It'll swing an 11x7 on 4s or a 13x8 on 3s.
