Carey sent me the start shaft for my Agile...and some shims to adjust the belt position. Currently, it is riding about 1/64" above the big pulley, not good.

With working 10 hour days and weekends, I was able to work on my Agile last night. I wanted to see what it would take to remove the clutch stack, if you needed to re-shim or change a belt. Well, it goes like this;

Remove the blades
Remove the main shaft and gear
Remove the fuel tank
Drop the landing gear and remove the muffler and motor (this is a good time to inspect the plug and piston)
Remove all the screws for the top plate, clutch stack, and lower bearing block (yes...unfortunately the bottom bearing block must be removed), so that means...
Remove one side of the frame screws, but only to the back landing gear mount. And you can leave the bearing block guide for the front boom spur gear screws alone.
Oh yea, unplug the two cyclic servos (aileron & pitch)

Once the motor was removed, the clutch shoe has wear on 90+% of the liner...on both sides! This is good, and there is the normal clutch liner dust on everything, LoL! The spark plug looks great, a medium to a little dark chocolate coloring. The base of the plug, on the threads, is a little black and somewhat wet looking, or rich. So this is telling me I have the motor tuned just right.

There was no surprises with the clutch stack other than dust. I disassembled the stack and measured the washer thickness top & bottom. 0.120" on top, and 0.095 on the bottom. I moved the pinion down 0.030" to get the belt more in the middle of the pulley. So I reassembled the stack and installed the start shaft, and then started reversing the disassembly process.

I had to stop at installing the motor as it was getting late and I needed to eat dinner. It took me about 1 hour and 50 minutes to get to installing the motor. I figure it would have taken me 2-1/2 hours to complete this process from start to finish.

Hopefully tonight, I'll finish putting my Agile back together and then start installing the Jewel Generator system I should have my Agile ready for a test flight by Sunday, however, we have rain in the forecast for this weekend, so I might need to wait until next week...right before IRCHA! I typically don't like to fly the week before IRCHA, just because something bad can happen right before leaving! I've crashed a few helis a day or so before leaving for IRCHA, so I try not to do any flying. But in this case, I would like to make sure my Agile is good to go!

I hope to get a lot of flights on it during IRCHA week.

Update...

I installed the motor, landing gear, mainshaft, and main gear. Everything went together with out any problems...well, except for one of the screw in the rear landing gear had snapped apparently when I tried to remove it. So I'll have to see if I can get a new block before or during IRCHA...before would be nice!

Installing that thin shim under the main gear was a pain! However, persistence paid off and it is in there! So now I just need to tighten the two top collars and run through the Spartan programming to verify/adjust the swashplate of level.

Raja will like this part! I started installing the Jewel Generator system. I installed the bottom coupler to the start shaft and then added the standoff's. I mounted the plate to the motor (generator) and slipped the coupler on the motor to do a trial fit. Well the standoff's needed to be 2-4 mm longer. The coupler on the motor is about .05 - 1mm away from the screws, basically hitting the rubber, and the same for the start shaft coupler.

I had some 2mm servo shims leftover from the conversion kit, and I used 3 of those to add the 2mm spacing needed...perfect! I started looking into how I'm going to where to mount the voltage converted and regulator and how to route the wires.

That's where I stopped for the night as my phone went off informing me of an emergency alert! There was a thunder storm North of us in Wisconsin and we could receive flash flooding from it. When I went upstairs, the super dark clouds had moved in and the winds were picking up!

Tonight I hope to finish with the wiring and start in on checking the swashplate leveling and throttle position.

Oh, I order a replacement landing gear mount from Motion RC. Should have it by Wednesday at the latest, and then I can test fly my Agile!

Mount

Hey Ray:

The mount should be just right but if its too tall or too short when we need to look at that and address it with Carey at IRCHA. Supposed to be a perfect fit, maybe you missed something in the installation, I sent Carey and motor and coupler to test fit it when it was being designed.

I worked on my Agile a bit more last night. I set and tightened the 2 collars on the main shaft, installed the fuel tank, mounted the Jewel rectifier and voltage regulator, and started routing the wires.

I need to make up a couple of "Y" connectors for the Jewel Generator and find a location for the LED. I would like to put it somewhere towards the rear.

After that, install the muffler and run through the swash settings and its ready for a test flight. I received conformation on the landing gear blocks, I should have them Monday.

Raja, if I used button head screws to mount the motor to the motor plate, I might have had enough clearance and not needed the 2mm shims. You will see it soon!

VERY IMPORTANT

Ray, please make sure that the screws you used to screw into the AXI motor are not too long!! M3x5 or M3x6 tops. M3x8 is way too long they will dig into the motor wires and short it out, if you go flying like that you can burn the motor.

The right length the screws should be flush with the thread ends on the inside of the motor case. They can come in very little but not much, especially on the side with the motor wires. The other side has more room.

Yep! I think the screw are 4mm long. It's the cap head that's tall.

My Agile is done! And its ready for a test, however, I won't be able to test it until Saturday. Too many things I need to do before leaving, and the rains have moved in again! Better to get it out of the way before IRCHA!

See you Saturday!

Car is loaded with 4 helis, Inspire and clothes. I just need to plug it in before I go to bed to charge up and I'm ready to depart in the AM to PA. Also on board are 4.5 gallons of fresh gas/oil mix plus a small container of 5oz oil in case I run out of gas I can mix another "emergency" 1.25 gallons to round out the week.

Looking forward to getting together with all the folks we talk to year round on the forums!

Ok, I arrived at IRCHA! We had to wait for the glider competition to finish before we could fly. They finished at 3:30 and it was time to test out my Agile with the Jewel generator system. So far everything seems to be working great. I need to tune the motor some as it is acting a bit sluggish.

Raja had arrived several minutes before me and was finishing up his first flight of the day. He liked how the Agile look and later I let him have a flight. Raja really liked the way it flew and noticed the tail is really reactive...so I might have it up a bit high. Still working on the fine tuning.

Doug Darby pulled in later and looked over my Agile throughly! He was flipping it around, turning it, pulling on stuff, basically placing finger prints all over it...LoL! I showed him a flight and even Doug liked what he saw. Doug gave me a muffler to try out, one of the newer RXJ...special addition, Doug style! It has a custom dent at the front bottom and a perfect samurai trailing edge strike at the front of the muffler!

We will try this muffler to see how the motor responds.

Well, it's late and I'm bushed. Need sleep as tomorrow is a full day of flying!

Looking forward to it

I think you should have better power with the modified muffler, those stock mufflers the tail pipes were marginal at best and after some carbon buildup on the inside they were bog city.

Interested to see how it goes tomorrow, willing to bet it will be much better!

Day 2 of the IRCHA experience!

Got four more flights on the Agile...and two on my N7. I tried the new muffler to see how it would perform without touching the needles. It performed better, but it was still a bit sluggish. Doug Darby suggested richening the high needle, but that made it worse. So I returned the high needle back to where it was and added an 1/8 more lean.

That brought more life to the motor, and now it was flying great! I also started fine tuning the radio (expo & normal throttle curves) to improve the stability a bit. The Agile flies more locked in. I let Raja have a flight, and the only complaint he had was too much collective pitch. I'm running +/-13 degrees for the added "pop" value.

With my flying style, I like my Agile to have that collective "pop" When performing quick/snappy maneuvers. I don't stay at full +/- for too long, just enough to change direction...a few milli seconds.

Raja enjoyed how my Agile felt and at the half tank mark, he started in with his style autos! He brought the Agile down sooooo slow, you could see a strobing effect with the main blades...right at the point of stall. Then sped back up to land.

More to come!

Here she is in all her glory

Watch at YouTube

Got to fly it more for real today including some autos and I'll say its definitely better!

For the most part, the weather was hot and humid. 83-92 degrees with 70-80% humidity. I didn't do much flying with the Agile waiting for Friday Carey's seminar. However, I ran into a couple of the KDS team and asked them some hard questions as to the fait of the company. I was reassured KDS is here to stay and parts are plentiful.

I told the KDS team about my Agile and they wanted to see it! The team pilots like it a lot and asked if I would demo it...sure! They like how well it moved as a gas helicopter and asked if I would leave it at their booth for display. Many pictures were taken and sent to the owner of KDS. He was impressed and wanted to see and know more about it.

On Friday, I brought my Agile to the seminar and it was a big hit! I felt a little unprepared when Carey asked me to talk about it, not used to speaking to a large crowd. I believe the conversion kit for the Agile will be a success, and a short kit should become available soon.

It is sad that IRCHA is over already, but there is always next year! I had a great time at IRCHA, learned a lot, and made new friends!
