Greetings,

I recently purchased a PHI Tornado II, or at least that is what I gather from the information at hand, and would like a little help to positively ID the bird. This heli had been crashed and came in many pieces. The coffin containg its remains also held a manual; Tornado II Instruction Manual which I digitized for review. This manual shows a heli with a different framing configuration. I have read that the "newer" Tornados had G10 frames and a rear mounted fuel tank, both of which I have. My rotor head appears to be a GMP Elite. Please take a look at the following photos (sorry for the quality - old cell phone was all I had) and advise if you will.

My plan is to restore this one, while avoiding the creation of a second Frankenstein. As such, I am pulling off broken parts, revese engineering them and machining new copies. I am doing this to some of the plastic parts too, replacing them with aluminum or G10. Most everything I need, I have been able to make or buy as a generic part, save for the main gear, which is missing a tooth. It's a 24 pitch delrin gear with 93 teeth and a good 3/8" face width. I have a main gear from a Thunder Tiger on order, but I will have to adapt it to my auto rotation bearing block. Plus, it's grey in color, which I find most off putting, and one needs his or her mental wellness in full balance to properly beat the air into submission.

The manual is very helpful but as I have a different frame, I would like to see a diagram of its original setup. I can figure it out to be sure, but I desire to get it put back together as close to OEM as I can.

Hi ahend,
Welcome to RunRyder, see you just joined.

I've owned both a Tornado and a Hurricane. You can see here https://rc.runryder.com/t482660p1/ some of my attempts to aquire parts from the last owner of this company.

The lot I got is not a lot, but I thank God a lot for the lot I got!

Mikerobe,

Hi, and thanks. I actually did read that thread while digging for more information. The archived PHI website from another thread was quite helpful and gave me several images of the Tornado canopy, which sadly I lack. I eventually need to find a one from a similar heli but I'm not sure which one would make the best match.

As far as parts go, I figured I was on my own based on what I had gleaned from the Internet. That works out ok with me as I rather enjoy tearing things down, measuring parts and rending CAD models for them, then machining copies from raw materials. This is sort of engrained in me from an early tool and die background. Fortunatly, I have access to a Bridgeport and a lathe.

Finshed a few parts tonight and thought I would share....

New lower frame set. This is made from some 3/32" G10 sheeting I picked up from McMaster. The G10 is actually green. I had to paint it black. They need to be deburred and cleaned, then should be ready to go.

Tail rotor transmission. 6160 Aluminum, buffed to a polish where it can be seen. The original plastic version had some bearing slop. I lightend it up a bit and may do more to it in that regard.

Weekends are Great!

Welcome Ahend....
You got to love having the knowledge and skills to program and machine your own parts. A big plus if you have access to CNC machines....hehe
Looking good and keep us updated on your progress.

YES... YoU puLL stART ! ~~~~ NO... it's NoT a FREAKN' Nitro !

I used to fly for PHI, and at the time there were no parts for the Tornado II when PHI Closed down and moved from Ohio to Georgia.
