i think you may still find some binding at 65 i have mine at 50 and there is not a lot of room on either end. i think someone suggested the Gaui 200 paddles for faster flipping.

+1 for flybar weights. Expo just makes your heli less responsive to control inputs so it may feel less twitchy but it's no more stable. The gyroscopic effect of the weights will actually dampen the heli against twitchiness from you or from wind or anything else.

Well, I had the old tail hub, and I had major issues getting it working right. I did get it working right though, and then I had trouble getting someone to film it. I got a lot of film like this first one, and then my son came out one day and he was able to get it pretty good in the second video. The heli flies good, but it's not like my bigger ones. Finless did a flight review and found the same thing - basic verdict is that it's fun to fly but it's a novelty heli, and it's moody, can be mushy in the wind, and don't spend your whole life trying to get it to fly like a bigger one. It takes some getting used to, and you'll think it's twitchy and powerful at first, but after a while I found it to be kind of mushy and weak - I just put the 16 tooth pinion on tonight. Carbon blades are a must.

Trex 250 too fast, LOL! (4 min 52 sec)


Trex 250 not so fast this time! (4 min 55 sec)

BTW... not a build video, cuz there's nothing to build, but I'll have a video review of the Blade mSR coming up. If you subscribe to my channel you'll be able to catch it. I won't post it on this thread. It is a cool little thing - flies weird for a single rotor.

I had to change my main shaft and have a question. In watching your video, you mention a spacer that goes on first. Is that the brass colored spacer on the main drive gear or is there another spacer used? Thanks!

There is the brass spacer on top of the main gear - that one is easy to lose, so I mentioned it. There is also a flat washer on the bottom of the gear.

Thanks Jasmine!!!

Those videos were a HUGE help.

I was a bit worried coming from E-fite 4CH Blades to a small CCPM, but these videos really helped calm my nerves and dayam I am not regreting my Align T-Rex 250 choice!

Jasmine...Good to see ya in the LHS last week....I went ahead and got the little 250. Started to wait for the 250 SE, but got a good price on the 250 super combo that was in stock. I will be reviewing your build videos for tips. Any thing you would do differently today?

Yeah just get all the upgrades right away... metal bearing blocks, metal tail drive, metal tail shaft, metal rudder servo mounts, and change the ESC to something better.

Silly question but, what would I get out of a better ESC and what would you recommend for someone with a small budget please?

Some people have reported the stock ESC failing in various ways - this happened to mine as well. The Castle Phoenix is a little smaller in size, has a better BEC, better governor mode. I use the Castle BEC with it as well.

Just wanted to say huge, big, crazy thanks for all the killer videos. I'm hooked on these friggin things like a junkie chasing the dragon!

Your build on the Trex 250 helped me sort mine out before actually giving it the once over.

Keep up the great work and hopefully HOPEFULLY I'll be able to fly like you soon!

Default CCPM Interaction

Howdy gang, had some trouble with Hovering with the Align Manual settings, so going to try Jasmine's set-up.

In her video set-up of the DX-7, she mentions leaving the Travel Adjustmentments at 100% with a mention of CCPM Interactions (around 12:43) in the video... I did not see a follow-up for the CCPM... I know Bob did one in his Techroom (CCPM Part 2)... would the "endpoints" be the high/low values on Travel Adjustment?

Second Question- apart from the CCPM interactions above, what would you gain from having Travel Adjustments over 100%?

Thanks in Advance!
