Squadron Settings Added
I have now added (see right) to the blog the settings for each of the heli’s in my Squardon. Hopefully this will help people in getting a start in setting up their own heli’s.

T-Rex 550E or 600E?
Good info here, http://www.helifreak.com/showthread.php?t=224540, if you can’t decide which one to get (ho hum..) Also a good photo on page 1 of the full Align range.
Protos Tracking… SOLVED
Well after a mamoth amount of messing around I finally got the Protos working again yesterday. Here is the run down:
- To sort the tracking out I was recommend to get new thrust bearings in the head as it was notchy and they had never been replaced. I did this and it tracked fine 🙂
- At this point the tail wasn’t behaving properly and it took ages to spool up to speed. I took the tail apart and discovered the belt was twisted inwards. (Think of a loop and rolling it like a rolling pin not twisting). This solved the spool up speed but the tail was quivering and then kicking 90 degrees at random. Very unnerving.
- After some poking about in the wires it turns out that the rudder servo link that goes into the gyro cable was loose! Thus sometimes it was working sometimes it wasn’t. Once I put this back together firmly all was okay! 🙂
All in all a bit of a nightmare but I got there eventually. It’s now flying fine and I can get back to it now…
Turnigy nano-tech
Turnigy 2650mah
Just ordered a new 6s 2650mAh battery for the Protos from HobbyKing (see here) for $51.99 (£35) delivered. The nano-tech series has just been released and claims 25c to 50c it will be interesting to see if what it behaves like.
I currently have 2 Turnigy batteries for the Protos (2450mAh and 2650mAh) and think they are great and good value for money. They don’t get excessively hot whilst doing 3D and so far have balanced fine.
Will let you know when I get them in 10-14 days time…
T-rex 250 SE Manual
Found this on the web and thought it might be useful to post here. Align T-Rex 250SE manual
Protos Tracking…
Ever since the last crash with the Protos there has been an inability to track the blades. They just seem to keep going off track. I have no idea what it is but someone at the club suggested that the thrust washers in the head may be off. Who knows!? Getting really annoyed at the moment because all I want to do is fly not mess around trying to get it off the ground..
Aileron Tic-Tocs
Been practising these on the simulator loads this week. Going to have to give it a go this weekend. Any tips would be helpful!
Useful pinions for T-Rex 250
Just found this and though it might useful for people with T-Rex 250’s, http://www.scorpionsystem.com/catalog/accessories/pinion_gear/04pinion/ it’s a pack of 14t, 15t and 16t pinions with grub screw holes. It’s for Scorpion motors but fits the stock one.
First 90 size fly!!
Went flying today, even though it was quite breezy. This meant I was flying the Protos all afternoon, and I have to say I am beginning to really enjoy flying it. The recent pinion change as made it a lot more stable, and not so “manic” this means I still have the poise and precision with it but without it going mad all over the sky. Also means lots of fun!
Whilst I was there a good friend offered his T-Rex 700 for me to have a go with. Naturally I was very nervous as its £1,500 all up, but thought a few circuits should be okay. Duly taking off I couldn’t believe how stable it was, I only intended to do circuits but just had to try it inverted. So I did. Again so stable – even in the wind. I really wanted to have a go at it now, but landed it and asked if it was okay to tic-toc, it was. So I took off again and gave it some (minor) welly. awesome, tic-tocs beautifully, no need to use full stick and it just sits there. Did some more inverted and horizontal powers, and it just took it up. Very impressed..
Hyperion Destiny for the T-Rex 250
After having some immense fun with the pocket sized T-Rex 250 I decided to upgrade/replace the motor with a Hyperion. Technically the same as a Scorpion motor (as they are now owned by Hyperion) I’m expecting the performance to be slightly better than the stock motor (3200 kv) as it’s a 3900 kv but I also think it will run cooler. When I changed the motor in my Mini-Titan for a Scorpion it was significantly cooler.
Hyperion HS2206 as supplied
Anyway this now brings me on to head speed and throttle curves. I run a 16t pinion on the T-Rex which is not listed in the manual but gives me (in theory) a head speed of 5411 at 100% throttle curve (http://www.readyheli.com/headspeed-calculator.html) or 4329 if you believe a popular used spreadsheet. As you can the differences are huge so I tried using these two calculators to match the figures given in the 250 manual. There was still huge differences, so if anyone knows a decent head speed calculator then let me know. In the mean time the only conclusion is to try the 250 with a 90% throttle curve and see..
