Default Wanted: OS-91 VRDF JMP Machined throttle arm

Hi all,

I am in the process of building a Parkinson Barracuda with ducted fan with a OS91 VRDF.

Was wondering if anybody has a machined throttle arm made by Jet Model Products (JMP). I understand the stock one that came with the motor sometimes fails, so looking for a better quality one.

Thanks for any help,

Have you tried calling Tom at Jet Model Products? 816-331-0356
It's not listed on the site, but he may have old stock still.

Yes, I tried Tom, and he looked through what he had left, and no luck.

You Rock!

If you do have one, I am very interested. I am trying to eliminate as many problems that others have had.

I only found 2 machined OS factory in flight fuel mixture arms. You slide it over your needle valve and tighten the set screw and hook up your servo. I don't think it's what you were looking for. Sorry. 💥

Speed Junkie,

I am going to use a in-flight mixture control. so I don't think those will work for me, thanks for looking though.

Your looking for the one thats goes on the throttle and its about 1/16 or 3/32 thick. use to mount ball links. I'll take a look tonight in my D/F stuff. I wish they make a rod for the .77 I miss those bad doys.

Dwane,
An unbreakable throttle arm for your OS-91 VRDF is coming your way. Watch your mailbox.
Mount a HD screw-on ball link to this arm and you should be good to go.

You da man. Thanks Art.

I also received the invite to your jet rally, me and possibly a couple friends are planning to attend.
Really looking forward to it, as I have seen only 1 turbine jet in the past.
