python/ greeves

[off2fly]

Anyone built a python 100 w/greeve's?Wondering about the mount's.Thanks for any help!

[off2fly]

Well I got the greeves in and thought i would post a few pic's of how i did it.I had to cut about 5/8" off the exhaust exit tubes to get them in,you also have to knock the rear of the canister tunnel ,its really well thought out by qq aircraft!The rear mount needs to slide over the tubes as you install them,then glue in place,fits perectly!QQ said you don't need the front mounts(Sized for cans),but I used it since it was already there.I used 5mm od silicon tubing with smaller tubing inside that to make the mount snug around the greeves pipes.I've found out also if you clean the connecting ends of the headers and pipes w/alcohol, then heat the coupler up with a torch before pushing them on and clamping while still hot they never leak.Hope this helps somebody and hope its accurate!Oh yea you have to grind out a little below motor mount to allow room for the headers.

Thank you for all the help you provide for us all!Oh yea i'm putting pb royal on this baby too,way overkill but not much difference w/weight gain when you weigh a couple sw's and reg's i love gadgets.

The weight difference is very insignificant. Matchboxes and regulators will end up weighing the same

A lot more protection w/pb,the pb is a great product,we are fortunate to have stuff like that available for RC nuts!

Off2fly,

Let us know how you like the performance of the Greeves. I'm planning on putting a set in one of my planes. What prop are you starting with?

I have them on my 120" Yak and the power is ballistic!I'll let you know how they do on the python,100.

I have a set on my QQ Python and love the power. It rockets out of a hover and the sound is better than the can's I have in most of my other planes. I am just about finished with my 120Yak, it to has greeves pipes. It was going to have a DA 170 but there not ready yet and I want to get it in the air so I will be putting in a spar 150 until the 170 shows. I have been told that the power with a 150 and greeves is plenty. I can't believe that the 150 will pull the Yak as well as the 100 in the Python but we will see. You will not regret putting in the greeves on your Python, I wasn't.

What header length and prop are you running?

Scott,my yak ended up about 42# and the power is unreal,you can do three snaps vertical and its still hauling arse!

28/10 and stock header length(not sure length DA told me not to cut them for the 100,just leave 1/4"gap between headers.Let me know if you hear any difference.Thanks, Vann

[rusty55125]

I used the standard length on the Python, not sure what that is. I am just finishing up the engine install and noticed that the headers are a little long on one side. What do you have the header length on the 150 and QQ120 Yak. Do I need to cut the header or put more spacers behind the motor. Sorry for asking this question on a Python thread.

Rusty,I cut my headers to 9 3/4"and left a 1/4" gap between pipes and headers for a total length of 10".The great guys from DA told me to cut a pc. of solder 10" long and lay header on side,end of solder start at top of flange and stay at center of pipe through radius and cut at end of solder,less 1/4",make sure pipe and header don't touch in coupling.Mine fit perfect!
