Sounds like a reasonable weight; good job!

Hey Spridal;
Anything under 20 lbs is good to me!! A tad nose heavy I can deal with!! Like the old saying, a plane that is nose heavy will live to fly again, but tail heavy will have a very short flight!!! Remember please post your flight report!! Also I will trade you some rain mix with snow for the sunshine you will have for this weekend!!! Do we have a deal??
Oh wait, I know the answer!!!

Idon't think Icanmaiden this weekend due to other commitments. Ihave next Wednesday through Friday off so I plan to maiden on Wednesday (week from today). Iwill of course post my flight report after the maiden.

Spridal, Looks great, but you may have a problem with engine temp, having the cowl enclosing most of the cooling fins. You may want to baffle or cut an openning in the front of the cowl. Just something to be aware of.

Thanks, I do agree and I actually created a duct that will carry cool air over the unexposed area of the engine. I will take a pic of inside the cowl so that you can see how it was done.

Want to setup an electric 12s version. Going to use the rimfire 50cc motor on a castle hv 160.
Is 12s going to be enough?

hidaven:
May i ask why you want to go electric? Seems to me that you will sacrifice either performance or in-flight time vs gasoline. What is the advantage of electric power?

wjc - flight time, maybe. But sacrifice performance? Many of the electrics I'm seeing seem faster and more powerful than gassers.

Slow and Steady

Can someone tell me how many flights you can expect from 12 s battery set up before the batteries have to be replaced?

edwal07

If you have all your information IE: motor, esc, prop, plane weight, battery info. You can go to the Castle Web Site on the Motor Calc and it will tell you. Ihave a 50cc size Reactor with 2 6S 40C 5000mah in series and I get about 7 to 9 minutes depending on throttle management.

Guys, this plane will do fine on 12s. In fact tower hobbies had one at the neat festival. I have a bunch of 6s 5000 lipos so I'm good to go. Performance should get me 7-8 min of nice flying.....just looking for anyone who either built one like this or has info on the electric one flown at neat.

I think the question S&S asked was essentially how many times lipos can be cycled before they require replacement, not now long will they power the plane.

Here are a few pics of my Revolver before decals. As you see I used the stock choke servo mount and mounted the throttle servo in the motor box. You will need 2 pieces of 1/2" basswood square stock to space the servo away from the side. I used screws and glue to attach it, glue on the inside and screws thru from the outside. Works great with solid linkage and a straight shot to the throttle. For the choke rod I used a piece of music wire from the choke arm, and ran it thru a figure 8 tie wrap on the motor standoffs to the left front opening of the cowl. Then once you get it situated tie wrap the figure eight above and below the wire to hold it in place. I have this on a couple of my planes and it works great. Same idea as Aeroworks uses.
All that is left is decals, control throws and balancing. Hopefully this coming weekend will be a maiden flight day, depending on the weather. I will post final weight once it is ready.
I am also using G-Force 2S 3300 receiver batteries with MPI regulators. The ignition is powered by a 2500mah 6v Nmh battery.
I would rather of had the DLE 55RA and the rear muffler but the DLA was on the bench and you can see the clearance Ihad to cut in the cowl but it still looks good.
Enjoy the pics. Will post more after the maiden.

Nice work.
Can you post some pics of your tail linkages and throttle servo setup?
Do you have Savox all around? Let us know how they work out.
Where to you plan to balance her CG for the maiden?

edwal07

Sorry, I misread the question. I have used my lipos over 40 flights and still going strong!

Ed - she looks beautiful! Looking forward to your flight report.

edwal07

Sure, I still have to pull the cowl off again to secure the fuel vent line. The tail linkage is alittle further back in the posts Page 8 post 191, I used Aeroworks horns and control rods. Savox all around except for throttle. They are 146inoz at 6v so for me that will be fine. I fly more pattern and sport type flying so they should perform well. I have heard good things about Savox so we are willing to try them out! I did opt for the Sullivan 24oz fuel tank as the stock one is a little huge and the inlet is not centered and I like the backset on this tank, again it was on the bench and ready to go.
I really like the look and the style. Its looks fast just sitting. I plan on using the listed CG to start and then work from there! I think it will be a good looking bird once the decals are on! We will see! And I will post pics prior and during the maiden and let you know how she flies!

Wow, that prop looks awesome, did you painted it like that??

edwal07

No, actually it came from Troy Built Model's just as it is! I have another that is different but this one is red and whiteso it is a pretty close match! THANKS!

Nice work on the elevator and rudder linkages. Did you install the elevator half servos per the book, with one servo arm up and the other down? If so (and you said you fly pattern-like), do you see any assymmetry of the movement of the elevator halves? That is, do they move in plane with each other?
Thanks

edwal07

Yes as per the instructions, but turned them toward the front to use the longer Aeroworks control rod. I tried to keep the moment (not movement)"the starting posiition of the armsthe same" viewed in a horizontal plane. I haven't checked it yet but just eyeballing they seem to be matched. I will check and let youknow when I set the control throws! We shall see! Looking at the arms depicted in the instructions you will note short arms and I would bet they are close to being equal in moment on each side. Moving the linkage inward toward thecenter to achieve an equal "starting point"would decrease any assymmetry and should come out the same. However I am not an engineer, and I may not be explaining it correctly. In my theory if they are equal in length of the arm and are close to being even looking straight from the side the throws should be equal. And I may be wrong. I will measure them and find out and let you know. That is an excellent question!

(9:50PM) RESULTS: The measurements are in MM's. With the plane sitting on a firm mount, not tailwheel. The measurements are as follows:

Righthalf Lefthalf
Up elevator: 225 225

Centered: 170 170 (both halves centered prior to measurements using sub trim)

Down: 115115

As you can see they are equal. No throws or travel has been set. This is with subtrim to get the halves equally centered on each other. WOW, I am amazed as they came out exact and I checked three times to make sure it was correct. I am using 1 1/4" SWB arms, using the 2nd hole from the end and the ball at the last hole on the control horns. I am pleased! However I appreciate your question, now we know!.

hidaven

Ed, which motor do you have in the reactor? Prop, esc? Maybe ill just build the reactor......

wjcalhoun

Ed
Thanks - nice work on the build that your throws are symmetrical up/down, and port/starboard to the mm. Good information.

Slow and Steady

Ed, Looks great! Enlarged all of your photos; great work. Really like your trimming of the cowl and the neat interior layout. This plane will definitely be as or more popular than the venerable Super Sportster, as a great all around flyer. Bet it will float in better than the Rev 70.

Thanks WC, that was my question, I should have been more clear. My concern for Lypo over gas is the long term replacement cost of the batteries after they have reached the end of their service life. I already have over 70 flights on my EF Extra, after only 3 months, so service life would be an issue. Need replacement after 100, 200, 300 flights?
