MA XCELL graphite gasser

[cehspikey]

I'm glad to have access to a new forum that will talk xcell I bought a xcell gasser and before I could even assemble it the other guys must of started playing there games. No xcell posts or information for months.
I have a MA EXCELL graphite gasser with GV1 governor GY401 gyro with digital servo, 710 mm main blades, CPD4 copilot flight stabalization system, stator gator for gy401, futaba s9001 servos, futaba r149dp receiver, futaba t9chp transmitter.
Let's get over rr an rm and everyone tell me ideas on setting up this HELI.
Thanks Cehspikey

Well sounds like you have everything you need.
Is the heli built or still in kit form?

1st. The 9001 servos may be a little underpowered for the gasser unless you just plan to hover it. The 9001 servos only have 53 ozs of torque
2nd. The 710 mm blades will be too long to use with the stock 31.5 inch tail boom and the stock tail blades that come with the gasser. You can use 700 mm main blades and 100 mm tail blades together with no problems.

I am not familiar with the Co-Pilot that you mentioned. If it is similar to the one that FMA has it should work well. Make sure the Co-pilot will work with a PCM receiver.
The Stator Gator is a sensor for a governor for the engine rpm. You listed it as being for the GY 401 which is a gyro. I hope you meant for a GV1 or another type governor.

Hope some of this helps you get started. Just ask and we can help you out.

I've building heli all winter it's completely assembled now.what would be better servos to replace the 9001's. The 710mm blades are what came with kit it looks to me for the main blades to strike tail blades they would have to flex all the way bown an hit the boom???. It the fma copilot and it will work on pcm. The stator gator is for the gv-1 . how about .Some pitch curve an throttle recommendations. Or any other recommendations somebody can throw my way.
Thanks DAVIDH for your reply.

Chuck,

I am not particularly familiar with the Futaba servos lately, but any good quality servo with 90 ounce/inch or more will be what you need. You can use a good quality servo for throttle that is slower (.23 works fine) and actually a slower servo on throttle works best for the gas motors. I use JR 4131's and 8311's in my gas machines.

If the machine came with the 710's check to see if the boom is 33" in length. If not, David is correct that you cannot use the 710's with the 31.5" boom. The gas machine needs at least 100mm tail blades and this would make only 690-700's possible on this machine. Believe me, the blades can hit even though it does not appear that they can :shock: .

Throttle curves will be different than the glow machine. You will still use 0% on the bottom and 100% on top, but the gas machine usually hovers between 15% and 35% throttle. I use in normal: 0,12.5,18,22.5,100. In Idle up:100,38,25,38,100. This is set with the servo and throttle arms parallel at low through high (both arms pointing the same way and having the same throw).

The G-231 motor will handle 12 degree of pitch easily. The G-23 will usually handle a max of 10. The 12 degrees on the G-231 gives nice rocketing climbs but can and will cause blade stall when cyclic pitch is added. It is best to get the machine to use -10,0,10 or -11,0,11. I use -10,0,10 in idle up. For normal I use -2,0 and 10 and for Hold I use -6,0 and 11.

Make sure to set up all of your linkages so that when at zero pitch everything is at 90 degrees and centered, even the bell mixers (parallel with the blade grips). The links on the bell mixers may need a little bit of trimming to shorten them to achieve this.

What motor are you using?? Any clarification needed send me an e-mail or PM! :oops:

Hope this helps!

thanks BIGRCR have to digest info then may post or pm this is a great forum already overloaded my mind.

over loaded mine too , I was wanting to know about the throttle curves , all I like left to getting mine running is the throttle servo , tail , gyro , and mounting the rx , and put the boom on , thanks BigCR
big help here too
