Cons HS: Much to do with a Dremel to let them fit in the frame

I like both, the easier way is to use the Futabas

If so I will order some until I can buy the HS5055mg servos.

Hrm, Im really split between building a 250 myself and buying a Master Cp.

250 fbl kit 40$
Gyro+USB programmer 60$
Motor+ECS+pinions 35$
Rx 25$
Total 160$

Master cp ~140 usd
Brushless ecs/converter+motor(s) ?$ (not looked into cost as there's not much info out on brushless conversions yet)

Servos, battery's and charger omitted as it should be the same for both.

The cost will end up being Very close to each other as i without a doubt will go brushless and the Master CP will need to be replaced.

It basically boils down to

Master CP
no setup
6 axis gyro
+/- Plastic parts
New model coming in 5 months - Walkera style


Kit
Mostly carbon fiber/alu
Variable pitch tail
3 axis fbl gyro tweaking.
Fun/nightmare of building a kit yourself.
Easier to get spare parts.

You're forgetting some majorly important stuff...mastercp is VERY easy to repair, will survive minor crashes and if you convert it to brushless when you outgrow it you can move everything to a 250kit. Btw, the plastic parts have been a non-issue thus far and the frame itself is very strong.

I will say this though...I have no doubts that a well setup 250kit will fly better overall. I think that is the major tradeoff. More durability and less precision with MasterCP.

A 250 is very complicated to build and set up. There is very little compartment space for installation and margin for error. The chances are you will spend much more than $40 on the kit as you will need to replace some parts with genuine Align parts. My Trex 250 was built and set up for me by my LHS. Subsequently, I tried to build a clone and failed two times. I just couldn't get the tail to work properly.

The tail is notoriously difficult to set up in a 250. Recently, I had a crash because the belt lost tension in mid air. Although it crashed onto grass, it took me more than 8 hours to repair the damage because the construction is so complicated. If you build a 250, I would recommend that you get a genuine Align DFC combo rather than a clone. Otherwise, I would recommend that you get a 450 as your first build. The construction is similar but it is just much more easy because of its larger size. It is also much easier to fly although you should get some local help with a 450 because it can be quite dangerous.

New video to review added

Added a new video. This time I attached my HD camera to my hat.
I went too far away with the heli from the camera often and the camera is tilted.
Also the quality is nowhere as good as the other videos, see the video on the bottom for an exapmle.
This is the first time I tired anything but normal flying with the Master CP.
It flips and inverts well. After filiming as always I did better.

I am assuming the sun light is causing the big difference in videos.
Any tips on filming with a hat cam?

If you used a signal converter it would probably work but Walkera has receivers that are already built for that. Rx2702 would do the trick for example.

Get the master cp because like others said, it is a easy to work on design and your enjoy flying it more if your stll learning .

So, everyone has convinced me . Im going for a Master CP.

Anyone mind helping me with what extras/batterys i should order?
Im looking at a acuccel 6 from hk as charger. The master will be orderd from terence/chinese jade.

Edit: What mild 3d flight time does one get with 850/1000/1300 mah battery's?
And is there any point to looking for pinions with more/less teeth for the stock brushed motor?

Edit 2: Also, has anyone doen the genius/mini cp servo saver on a master cp? if i can get it in the air for now with that,id be able to get quality servos instead of looking into cheapo replacment ones.

Geezz this is sounding better and better all the time. Just may have to get one. I bought Exi pro 450 carbon kit + flight pack/ extra metal gear servos/ and good battey all free shiping for about $180.00. Belt drive and X-heli has five part Vid. on the build. Kit is 95% built allready. Plan on using either T9X or maybe Walkrea Devo 7 with matching Rx. Thats for later anyway.

Kit may be 95% built but with a 450 and higher you typically re-threadlock everything as a first step. That truly isn't a bird to take any risks with so make sure it's done right the first time so you have little to nothing to worry about. one last thing....if you have ANY parts where a screw goes into plastic, it's worth it to find a metal equivalent part and use threadlock.

Well then, iv finaly joined the master cp train and orderd one.
Ended up at 260 usd for heli+spares+battery+charger and shipping.

Edit: Has anyone tweaked a model in Phoenix RC so it handles like the master cp?

Tom, thank you for reviewing the MasterCP, got it last week and am blown away by its friendly personality. I know nothing about flying single rotor helis and have surprisingly not managed to destroy the MasterCP yet. it is far more beginner friendly than it get credit for.

Naturally I promptly had to try attaching a camera to the thing, and stuck a ReplayXD under the CG. beautiful out of the box.
My FIRST EVER - CP Heli flight with the RelayXD - (5 min 58 sec)


Somebody mentioned how strong this thing is, it lifted the 85g replay like it was not even there. so I stuck a bigger battery under the skids as weight (no cam) the MasterCP picks up 250g without blinking. THAT did not apply to 500g - it picked it up and made it to about 6 inches, i put it down right away.. but the thing is much stronger than I would have guessed.

BTW.. looking to get to know some heli pilots in LA.

Happy Flying.

Bo
