hi Isaac, i had this plane for a very short time, it went in on the maiden due to the cog being forward and running out of up elvator on the down wind leg. (poor inital setup and pilot error). i put a tower75 in mine and had to add a heap of weigth 300g+ to the tail to get the cog even close to the mark . i had robart mech retracts in mine they were a drop in fit. i hope you have luck with this plane and would love to hear how it goes.
cheers Greg

My local Hobby people had one in stock and i picked it up. I hope to
get started on it very soon, im thinking of going with the fixed gear
and later installing retracts I have some that should fit.

Probably will go with a OS46 for power I have one in another plane
and at some point get a bigger engine.

If it's the West .50 V1, go with a 9-6 for now, or 9-7 tops. Don't run 10 inch props on it. Use good fuel, 10-15% and syn/cas blend.

Well, perhaps it would have been better for me to say you cannot prop it for under 16K (per the instructions), it is ported/timed for that rpm range, and it makes it's best power in the 18k plus range. So, you could put a 10" prop on it as long as the pitch allowed it to turn up where it is happy. And I have never run a 10" on mine. Weston's instructions list a 9-6 or 9-7 as the first props to run. It's a high rpm wailer and makes gobs of power, but, it has very good manners and starts and tunes easily, and has a decent idle. In fact I was surprised at how easy it is to handle, not finicky at all. BTW personally I would highly recommend a bladder tank like a Jett or Tettra, although I am only familiar with the Jett tanks.

Depending on the frontal area of the aircraft you are putting it in, a 9-6 APC might be a good first choice, it pulls like crazy. The engine should unload to 20k or so in the air with a 9-6; pitch speed is 113 mph at 20k. To achieve 120mph, 7" pitch at 18.1K is the theoretical requirement, slip not factored into either figure. So, if the 9-6 doesn't do the trick due to drag, maybe a 10-5 howling away up front might be a good choice. I do not know if the engine will run happily on a 10-6, I don't recall anyone who owns one on this forum commenting on that. Maybe you'll find out it works fine.

Well, when that engine was on my Magnum, I was using a 9x7 APC Prop and was getting 20K

I have notreceive yet the airplane in my country yet, so as soon I made the maiden fly, I will keep you guys updated.

Then you have a good one! It will do the job fine. I didn't realize you already had the engine, that's why I was talking about larger props - now and again someone asks about that engine for applications it was not meant to do, you see. Cranking a 9-7 at that rpm, your Tomahawk ought to move along smartly. Let us know how it goes!

Hey guys, I just received the Tomhawk :-) The finish and construcction is EXELLENT! Also the cover looks verry good.

I order a set of Hangar mechanical retracs for this plane but I will say they will be to flimsy and will bend very easy. I think I will order Mechanical Robart ones with thicker wire struts.

The only problem I have right now is looking for time to buid it. I am in the proccess of finishing a T-34 mentor and eaven ARFs take me a long time to finish them :-(

BTW, I order it from www.alshobbyshop.com @ 169.95

For anyone planning to get the Tom Hawk be warned I found the Instruction manual
poor and the kit engineering when it comes to the rudder and elevator poor.

Im going to have to totaly redesign a way to work the elevator and may not use
the rudder, one of the things i found was the servo cut out in the horz stab was
misalinged with the servo mount for the elevator along with various other
problems in that area.

I was checking the elevator and rudder configuration and I dont like the factory Elevator & Rudder Torque Rods........... They only use one HINGE. So I will make my own Torque Rods with more hinges for a better assembly.

I have scanned the manual so you can see what I am talking about.

Also the factory fuel tank thats come with this airplane is very small............................................. ... I think is a 8 onz[:'(] I will try to put a bigguer one............I am going to use a West 50 with Weston Pipe[sm=spinnyeyes.gif]

Default RE: VQ TomaHawk + West 50 with Tune Pipe

I got my Tomhawk in the air and have had about 10 flights so far with a OS46 eng
surprisely its pretty stable in the air. I had to add a couple of ounces of weight in
the tail and i also moved the receiver battery to the tail but I found the main gear
is to far forward so its very light on the nose gear but installing a smaller nose
wheel will help.

Im not so good at uploading photos or I would show how I did my elevator and
rudder linkage as the factory setup was junk, also I threw away the fuel tank
because it had a air leak and installed a Hayes 11 ounce it fits well and is good
for at least 12min flight with a OS46.

Im looking to maybe up the power and install retracts but thats a lot of work so I will
see. As I said I will fly it while it lasts but I would not purchase another one.

Hey Isaac! That should be a VERY impressive combo. That West runs awesome and you will be fine with a 9x7- I would probably run a 9x8 since that is what I ran on that very engine---It pulled better RPM's than my Jett-50 [X(]

Keep us posted!

Ira- Try a 9x8 or 10x7 and she'll speed up. An 11x6 is NOT a very good match in this case.

Hey guys, sorry for my late reply, I was on vacation with my family

Well, I have not touched yet the VQ Tomahawk......................... I am finishing firts my Pantera heli with a YS 50ST and also finishing covering a Kaos wing. Then I going to beguing with the Tomahawk........................ To many toys

About the West 50 engine.......I am using a 9x7 APC prop with my Magnum airplane. With the 9x7 I am getting 20,000 RPM on the ground and this thing is ballistic

Can I use the same prop in the Tomahawk? Or since this airplane is more big I need to use another size prop?

THX

Ok thanks I did try a 10x8 and I think a 10x6 but so far the 11x6 has given the most
speed.

Hey guys,

ira d send me his pic of his elevator and rudder mods....... So this is full credit to him. ira d thx for sharing this info.

Here is ira d explication of his mod:

The way my setup works is I used two 1/4x20 bolts and
then drilled out three servo horns and threaded them onto the bolts that I put through sides
of fuse back by the elevators, two of the horns are on the outside of the fuse and one is inside
the fuse and is connected to the push rod coming from the elv servo.

I found some bushings from and old copier that I glued into the fuse sides and ran the bolts through them in essence I made a bell crank. Also I threaded the bolts into a sort of coupler and glued and taped them to gather so that both elevators are run by one servo. Hope this helps.

Ira

the mods look good. the first 2 pictures I noticed are the screw lock connectors on the horn attached to the fuse.
I would put a little bit of locktite on the screws that hold the control rod in. I personally hate those, I don't even use them for the throttle
A person at our field used one of them for his throttle and the screw came loose keeping the engine at about 3/4 throttle
untill he ran it out of gas. Just my .02 cents
