Just a few pics of my nice great flying cheap jet

Kool, Kinda looks like a B-70

Looks great. It would be hard to find a better flying turbine platform at any price. What engine is on yours?

I liked the flight characteristics of my DF Enforcer so well that I decided to build another for my first turbine. I logged 113 flights on the DF Enforcer, but don't fly it much any more since finishing the Turbine Enforcer. I'm up to 116 flights on it since finishing it a year ago.

Joe

That looks like a great model.

I flew a prop Enforcer as a delta 'trainer' before flying my Roo. Great airplane and I would love to build another for turbine. It's not the quickest building kit in the world (I'm turning into a bit of an ARFer) but it does fly brilliantly well. The addition of canards must make it even better.

Joe, I got most of my ideas from your Turbine Enforcer post. I have a Simjet 2300 turned down to about 20lbs, a 50oz fuel tank gives me 5 1/2 mins of flying time plus extra to land. Vertical is ballistic, this thing will climb out of site. Weight is just under 15lbs with UAT full. With canards I can do some very nice slow flying and landings are a breeze. (my Viper Jet is in early retirement)

Slick, your right about building, it took me a little over a month to build. I am also an ARFer.

Hi Joe

Here is several pic's of my delta wing enforcer

I have two projects i would like to do someday and a turbine Enforcer is definitely one of them. I had two DF converted Enforcers and loved them!
Myles

Cleve,
The Enforcer looks great. Now let's get it in the air.

Joe

Anybody though about doing a turbine conversion for EAM 80" Velocity XL?

George Thomas from Detroit put a SWB Mamba in a Velocity XL. I can't give you any details about the conversion except that it looked rather straightforward. It seemed to fly fine.

Joe

Wideopen,

very cool Enforcer !! Do you have any picture of the internals ?

Nice to know that people are still enjoying the DF conversion of the Enforcer. BTW, the original airplane still exists here in Maryville, TN. I sold it to a friend many years ago. I'm curious about the addition of canards. Who did it? It looks great.

Dennis Strege

here ya go

Thank you WideOpen [sm=thumbup.gif]

That Rx batt look so small [X(] .. but maybe you dont use digital servos

and what is the brand of your fuel tank ? Just looks like a drop in, nice fit [8D] It may helkp for future reference

and also, where did you get the Canards axles / nylon mounting / bearings setup ?

thx

The Rx battery is a Hobbico Hydrimax 6.0V 2000 mAh

2 Hitec 5645 digital servo for elevons
2 Hitec 5125 digital servo for rudder
1 Hitec 5245 digital for canard
1 standard servo for steering
2 mini servos for retracts/brakes

Fuel tank is 50oz. Dubro

5/32" wire used to make canard / steering arms / nosegear bearing and collars all to make up canards. All of the above came from Towerhobbies.

thx ! How many flights do you log with this batt without recharging ?

4 flights, each flight is only 6 mins. do to the turbine size/fuel tank a 12 to 16lb thrust turbine will give a longer flight. I was using 25lb of thrust way to much. I never checked the batt after 4th flight maybe I could have flown longer!

Would it come apart ? [X(]

Guys, I am now officially going to be building a turbine Enforcer after CHRISTMAS!
Can't wait to get started as I really love this little plane.
Tell me something, did you guys Strengthen the vertical fins? I was thinking about framing new ones from 1/4 x 1/4 balsa sticks and then sheeting them with 3/32 sheets. I also want them to cant outward at the top a few degrees (ala F-22) just for the cool factor of it.
Just got my ecu back from repair and my turbine is running sweeeet once again so I'm really anxious now!
I would also like to hear a few building tips on yours too if ya'll don't mind. I want to build the fuse permanently attached to the wing with a removable hatch for equipment access. Did anyone else build theirs this way besides Wideopen?
Any help is appreciated!
Myles

Myles,
Congratulations on your decision, you won't be sorry.

The fins definitely need to be strengthened. I used the 3/16" balsa stock that came with the kit and sheeted them on each side with 1/16" balsa perpendicular to the grain. This made them very stiff and they have held up well. I also reshaped the fins and moved them outboard one rib because I liked the way it looked and to add some additional stability.

That's the way I did mine. I also lengthened the nose by 6" and made the fuse about 2" wider.
You'll need to eliminate the center wing rib (W1) to make room for your fuel tank and equipment. In the process it is pretty easy to make the fuse as wide as the two W2 ribs. You'll have to make new fuse formers. I lowered the cover in the back to facilitate air to the turbine. A 64 oz. juice bottle makes a perfect tank right on the CG.

Here's a couple of pictures of my under-hatch area. There are more at my build thread:

I've been flying mine two years now and have 145 flights to date. Let me know if I can help once you get going on yours.

Joe

Thanks Joe, I will keep corresponding with you on this. I can't wait to get at it!
I bet I logged 200+ flights on my DF version before I retired it. One of my favorite airplanes to fly for sure.
Myles

Wideopen--Did you extend the nose on your version? How far in front of the CG did you mount the canards? How big are the canards? Finally, how much do the canards move up and down when the elevons move? THANKS Looking forward to starting mine next week.

If you extend the nose or add canards the CG will need to be moved forward.

Joe

Yes, nose was extended by 6 inches. Canards are mounted 24 inches in front of CG. Canards are 6-3/4 inches long at trailing edge and 3-3/4 wide. If I had to make them again I would make them longer and wider more closer to the composite-arf rookie with canards. Canards move up and down 1 inch with elevons, this was put on a switch. CG was moved 1-1/2 inches forward. Most of my ideas came from Joeflyer he has posted a link to his thread 4 post up from this one with lots of information.

[sm=thumbup.gif]Thanks Joe and WO for the great advice and data. When I built my ByroBlaster version to earn my turbine waiver I did just the straight conversion. This time I plan to extend the fuselage, add canards, and move the fins out a bay. Bill
