ELECTRIC SHRIKE CONSTRUCTION
Since there is no more LANIER I must consider lucky to still have a shrike 0.10 kit in my shop.
This plane was bought two years ago when builders used to buy kits. I supose we are the few builders that exist since there are less kit options to buy in the market.
This plane is intended to be a trainer for a electric jet I already started construction ( TA-183 from RBC kits not the foam ones that are toys).
The equipment will be:
MEGA MOTOR 20/30/3
lipo 3S 3200 MHA BATTERY
2 STANDARD SERVOS
ESC 60 AMP ( HAVE TO BUY)
The only modification looking at the plans to make this plane electric is:
1. Moving firewall 2 inches in the front.
2. Making a battery tray in the tank and accelerator servo area.
3. Adding a bugee hook. WHY? better to learn with this one how to bunggee a plane, never done it.
Will be adding some pictures as the build starts.
Think this project will last 2 month, taking in consideration my real work, family, etc.
Cheers,
Juan

RE: ELECTRIC SHRIKE CONSTRUCTION
Had another building nighe with lots of balsa dust. Not sure why I´m always congested.
This time I build:
Battery tray
Sanded the nose round
Cut the electric screws to size
Sheeted the bottom
Thought my motor was to big, but read here they have build them with 0.46 CI glow. Feel preaty relaxed after this.

RE: ELECTRIC SHRIKE CONSTRUCTION
More building pictures after several weeks of no activity.
Build a motor hatch for easy motor placement. Involved cutting it with a saw and then sanding and adding new wood to have a nice parting line.
Carved a ram air duct for coolling of motor.
Reinforeced the main spar with a carbon tube in the inside.
Started to build the first wing half. The dificult part was how to hold the plane in place.

RE: ELECTRIC SHRIKE CONSTRUCTION
I like it!
The first time I visited the local airfield, a guy had a shrike there. I could hear the whistle of the wind over the surfaces as he did high speed passes. (I could also hear the motor screaming.. tuned pipe)...
From that moment I wanted an electric shrike.. just to hear the sound.
Alas.. I never bought a kit, and are no longer available. I'll have to keep my eye out for one some day.

RE: ELECTRIC SHRIKE CONSTRUCTION
Almost done with the shrike construction.
Pending a final sanding and covering.
Added the elevator servo in the aft fuselage for battery space, and relocatedte the ailerion servo.
Added all the gear to the plane and seems that the CG is OK by just moving the battery.
This is not a light plane with this electric configuration, for sure is more than 2 pounds.
I´m hoping to get all the juice out of this motor moving a 9 or 10 inch blade with the biggest pitch the esc or motor can handle.
cheers,
Juan

RE: ELECTRIC SHRIKE CONSTRUCTION
Never put a flying review.
This plane flies fast and was hard to land with 3s 33200 battery, so now using 3s 2200.
Did some serius crashes that the plane survived, so can tell this is a flying brick. The land moved and hit it in low aprouch, a PVC pylon got in the way and breaked the pylon with dent in a wing. Broke a tail in learnig to land and loop at the same time.
Planes now day are build so lite that any minor crash breaks them.

This plane has been my work horse for the last years.
For sure is very robust and has taken a lot of beating over the years. The last was a fail bungy ramp launch that ended diving into the ground braking nose.
The original motor was to big and over wheight(mega 20/30/3) for today standards is old school. To big for the 400 watts it gived. The komtronic motor was to slow with the 4.1 gears, and the new motor is a Turnigy l2855 2100 kv with apc 7x6.
Think that with this motor combination plane will be balistic. Had to use a lot of lead upront simce could not find a spinner that will not self destruct with 20,000 rpm.

Here is my first atempt into bunge launch with my trusted shrike. I use this plane for edf training.
My 4 atempt was failled due to spinning prop before plane realeased from string.

Thanks for updating your post on the Shrike ! I have followed this thread back since you started it... I have a 40 sized kit tucked away that will end up electric as well SOMEDAY

Hey, Juan. Glad to see you're still at it. If anybody's interested, here's the plans and templates for the 40 sized Shrike.
Also, I'm looking to sell my 46AX powered Shrike. $100 + shipping if anyone's interested. RTF if you have a FAAST transmitter.

My intention ins using the the motor Turnigy l2855 2100 kv i did not went to good since in 3s the motor wants to go to 20,000 rpm so can say NO to the average spinner and props. The prob adapter and prop in above pictures could not manage the high rpm. At half throtle the vibrations were terrible. Had to limit throtle curve to maiden.
The firewall was thick and there was to litle shaft for the prop adapater to grip well and this was part of the problem. Solved this by using Dremel tool and making it 1/16 thick. Glued a good quality 1/16 plywood to reinforece to make 1/8. So now motor shaft is long enough for prop adapter to grip.
So at last was able to spin a APC 6x5 with out cone only nut at max rpm with out self destructing. The nut cone had to much mass that at high rpm vibrates to auto destruction, Using only a smaller nut has no problem.
Expecting to have a very FAST FAST Shrike with this combination.
Not bad for a 15 bucks motor having the performance of the old hgh rpm expensive glow motors.
Measured 18,000 rpm with 6x5 apc e prop
