Default Shrike .40 first flight question

Hi everybody. I am going to be finishing a Lanier Shrike .40 pretty soon. It has a Tower Hobbies .46 with the standard muffler and a dave brown aluminum spinner. I am looking foward to going fast! I have never flown a airplane of this nature before and am wondering what I should expect on the first flight. I consider myself to be a somewhat experenced pilot and have flown some airplanes that I considered to be pretty fast. (Mostly overpowered sportplanes.) However, they were no Shrike!! Being that the airplane is so short coupled, is the elevator really sensitive? Anyway.......The shrike is an experement and I am hoping that it lasts longer than a few seconds. Advise?

A friend of mine let me fly his LA .40 powered shrike and it was making a funny noise. I shrugged it off as being the silicone exhaust diverter. When I bought it down low for a high speed pass that funny noise was the wing in flutter. I handed the transmitter back to my buddy just before it went in. There was minimum damage. Aileron servo stripped.

After investigation it was found that the aileron linkage ( 1 servo and torque tubes) was a very sloppy installation.

Balance it per the instructions, and keep the control throw reasonable.....and you will have no problems with it.

It is a very smooth flying airplane.

You have a throttle. Use it for a while if needed. The plane will fly off of hand launch at half throttle.

Take the time to double check all of your linkages, and be sure to seal the control surface gaps.

Enjoy!
Bob

I typically use the same covering material used on the rest of the plane. Or, you can use simple clear tape.

I put well over 100 flights on mine and the air frame is still good. I agree with Bob that balancing it is very important. I extended the hatch back so I could put the Batt in the very rear of the fuse. The Ailerons are more likly to be too sensitive then the elevator.

Ah one note here is on the elevator. Max throw will be needed basically for landings. Frankly you can't get enough and make your approachs shallow or it will pancake

Take care to seal the leading edge really well or better yet wrap the covering well over the leading edge. I was doing high speed passes from a split S when the covering exploded off the whole left side of my Shrike. It was like a gun went off. Thank goodness the wing is sheeted 1/4 of the way back and the bottom half did not come off. It tried to run me down but I was able to land safe.

Have fun.................and keep on your toes

I built one and it sat engine less until my uncle found a 1972 OS-MAX H in his basement. Has been one of my favorites for several years now. It really scoots along. I echo the sentiments on the balance. I use the recommended throws but find if I pull to tight of a loop, it will snap out. So be careful there. The initial hand launch is a bit scary, but once you get a hang of it, you will be fine. I also run 30% fuel so I get a smoke trail just in case as this bird moves. Of course I run 30% in most everything I have.

Also, make sure you have a big contrast from top to bottom. You can get disoriented fast with this one.

Just hang on and have a blast! Great kit for the $$$

Jason

This is my Shrike 40 with a JEN 56 (A 40 that thinks its a 60) with a tuned pipe.

Flies well but I advise 50% dual rates on ailerons and 50% expo and 50% expo on elevator as the controls are touchy and respond to the smallest input.

Its a blast to fly and have put a 10*9 on mine to push the speed.

I use carbon rods for all rods and two servo's for ailerons as you can use your mix settings to add in flaps on the alierons which if mixed with elevator can slow you landing speed to a slow speed but I mainly fly it fast and furious and land fast as you tend to lose elevator as you slow down.

I also fiberglassed all the fuse and the blue area as the fuse is the weakest point in the construction. Added rear hatch for battery and sheeted the stabilizers as big lump of lead on the front. On the next version I will shhet the wing to R3 so I can mount the servo holders to reduce drag on control rods.


A very smooth plane to fly.

Howdy, here is a swedish version of Shrike called Vildkatten(Wildcat) designed by Nils Hollman in the late 80ies. Found mine dirt cheap at a swap market, fixed it up and fitted a piped MVVS.45 which gives lively performance. Can be handlaunched or started from a dolly. Small foreplane is fixed and claimed to produce a vortex to aid low speed performance.An excellent flier.
Nice thread, hope it will be revived now.........Cheers/Harald

I was just wondering how your first flight went. I flew mine today, first time, with a Tower 46. I was very scared, because the airplane was about a pound heavier than they said it should be. It really staggered for a bit on every hand launch, but flew very well when up to speed. I took the Tower 46 out tonite, and substituted an OS 40 LA. Weight went down by at least a half pound, and there is still enough punch to go vertical. Can't wait to try it.

Like the guys say, approaches must be fast and shallow, otherwise you run out of elevator trying to keep the nose up, and she splats in.

More fun than I've ever had. What a blast.

Default RE: Shrike .40 first flight question

Has anyone ever put a landing gear or retracts on a Shrike 40? I'm asking because I'm thinking of building this as a 4th plane after getting comfortable with my Sig Kougar. Problem is that I don't have a place with a smooth enough surface to do belly landings - either very dry/rough grass or pavement, neither of which would be very kind to the model...

Thanks,
Jacek

Here are some pics of mine, my biggest complaint with them is they all come out nose heavy, mine could use a couple more ounces in the tail but I don't want to make it any heavier.

Jeremy, WOW..great airbrush technique you have...!! Well done - I´m really impressed.
Yes, the swedish Wildcat (post#13) also comes out nose heavy so I had to place servos, batteries etc.. as far back as the fuse will allow to avoid lead weights. That did it for me. You could also replace the muffler with a full length pipe to move CG a bit further back. Good luck..!
BTW, do you ever use water based acrylate emulsion paints when airbrushing..? Have seen that described in articles but not yet tried it.....Cheers/Harald
