Raptor 30

[spilmanr]

I am new to the Helicopter world. So here is my first dumb question. When I first bought my Raptor 30, I noticed that when I would start it, I was able to have the throtle stick all the way down and it would start. Now after a few runs it seems I have to set the throtle stick up some just to start it. I also noticed that it takes a little longer for the blades to spin up. Does this have something to due with the plug or is it something else?

Where is the trim set when you try and start it? The way I've got
mine set up, with the throttle all the way back (in normal mode, not
in any idle up or throttle hold modes) trim full down with completely
close the carb and kill the engine. Trim has to be mid to full up to
get it to start.

I'd double check your carb linkage setup and also double check your
radio settings. The Raptor manual has very good setup instructions in
it. Make sure it's mechanically correct before you do anything with
the radio.

My trim is all the way up so up it can not go any further. I have not touched anything with the trim or any linkage since i got my raptor.

What kind of radio are you using? You should have the throttle linkage
setup such that, with the throttle stick and trim full down, the carb should
be fully closed. With the stick full up, the carb should obviously be fully
open.

You might have to use a longer arm on the servo to acheive this and/or, if
you're using a computer radio that has ATV or end point adjustments, check
those to see if they can be adjusted to achieve the condition described in
the first paragraph.

Good luck,
Steve R.

I am using a 9CSuper controller. I really am glad you guys are giving me a hand but some things you say just still seem really unknown to me. I am thinking to help me in my need I may need to take some pictures and then someone can say that is your problem by marking the pic up!

[Steve R]

The 9C is great. It will make the setup very easy.

What I'd suggest doing at this point is to mechanically set the servo arm 90
degrees to the normal motion of the push rod with the throttle stick at half
position. Then make sure the throttle arm on the carb itself is in the same
position with the throttle half open. Now put the throttle stick at full
down and the throttle trim full down and adjust the throttle ATV's until the
ball links on the control rod line up with the servo and carb control arms.
You'll need to physically hold the throttle arm fully closed while you do
this. Then do the same thing at full throttle position while holding the
throttle arm on the carb at full open. You may have to adjust the length of
the control rod itself to make it all work out. If you do that, you'll need
to readjust the ATV's on the other end so that it all balances out. It's
easy work to do and shouldn't take too long.

Once you've got this done, you'll probably have to readjust your throttle
curves so that you've got the main rotor rpms you prefer.

Hope this helps & Good luck!
Steve R.

One quick suggestion. If you have changed the fuel you use, this might
affecrt the mixture. this can have a knock on effect to the tickover point
and obviously effect the performance. if the blades are taking longer to
spin up, is it because the engine is not "picking up2 correctly. Try a
couple of clicks open on the mixture needle (the knurled lump that sticks
out the side of the carb). if that doesnt improve things, try it 3 clicks
the other way.
My best advice would be to find yourself a club to get some hands on advice.
