Nice looking conversions Jim![sm=thumbup.gif] They look like proper R/C airplane engines.

The aluminum Hanger 9 mounts look like they were made for the Homelites. There's plenty of room on the webs to mount your throttle bellcranks too.

I look forward to seeing both Homelites running together.

Thanks for the update,

Ron

RE: RE: RE: RE: 33cc homelite
 

Ron,
I got both engines running today after supper. WHAT A SOUND!!:D It was like a for real bomber was sitting in front of my garage! I adjusted them in sync at a fast idle and let them go for a while. Of course, I had to goose the throttles a couple of times just for the fun of it.[sm=lol.gif] They definitely wanted to pull the bench over!![:-] Nice thing is...the vibration level with both of them running was not bad at all! At first I had them facing out of the garage but then I stopped them and turned them around so the white prop tips would be visible.

I think they're going to haul that plane just fine!

HEADS UP HERE!

''I live approx. 5 miles from Montana Rail Link's biggest switching yard and they use "Remote Control" on their switching engines, I wish I could blame them for my problems. (Probably not the same as "radio control"?)."

I too live near a rail line, and we have had lots of problems with interference when the train is anywhere near. FM seems to be fairly reliable, but the older AM equipment won't work at all. Just recently lost an airplane to this, and many friends have as well.

Good luck
AV8TOR

RE: RE: RE: RE: 33cc homelite
 

Thats just awesome Jim, I got goose-bumps looking at your pic's !! Man, I wish you could include the sound too! :D
[sm=sunsmiley.gif]

That's gonna be some site (and sound) when you finally fly your 110 with these puppys. If one 33cc Homelite can haul my 20#+ planes around, two of them should give you power to spare on a 30# plane. Have you speculated what your wing loading might be? I never got around to figureing out mine, one day...

I flew the little LT-25 five times today without a single glitch. I'm going to just use this radio for the glow powered planes and buy something different for the gassers. (I just don't trust it anymore).

Thanks for the input AV8TOR. I hav'nt had any problems with interference until recently, but it sure would'nt hurt for me to call MRL and ask some questions. I'll do that tomorrow and post an update.

A train went by the house today loaded with huge propellors and hubs (huge wind powered generators?), just like the ones I've seen in California. I drove down to the train yard and snapped a couple of pic's with the digital cam. this morning, including one of the "remote contol" sighn. Sorry they did not turn out so good.

Ron

Wow, one prop taking up 4 long wheeelbase flat cars?

Jim W.

RE: RE: RE: RE: 33cc homelite
 

Ron,

That first picture looks like it would make a nice flying site! ...except for the RF interference. Of course you have a better one!

I wish you could have heard the engines, too! you would have loved it!:D I think the 25s would have flown the plane, but if it get over 30# I'll feel better with these. The wings are huge, so the wing loading is going to be pretty low I think.

I mounted the engines on the nacelles and they feel very solid. Unfortunately, unless I cut big holes in the cowls I don't think I'll be able to use the stock mufflers, even cut down. I'll figure out something though. I can live with holes for the carbs but I don't want real big ones for the mufflers.

Jim

Hey guys...do you want to help lower fuel prices ? click here http://us.f132.mail.yahoo.com/ym/Sho...ad=b&box=Inbox Thanks Capt.n

RE: RE: RE: RE: 33cc homelite
 

Yeah, I looked out of my back door this morning and thought, what the ???. I see all kinds of strange looking stuff going down the rails, passenger plane fuselages, military tanks, armored cars, artillery guns, trucks, etc.

Jim, how about those wrap around mufflers? They have a short header that goes straight back and dumps into an expansion tank and exit below the engine. Or you could weld (or have sombody weld) up a custom exhaust system? I've noticed more power and a better idle out of a less restrictive muffler on my homelite, over the stock muffler. (sounds better too). By the way, that's a cool pic of your conversions mounted on the 110's wing! It' really coming together now.:D

Here's another pic of a military "convoy" loaded on a half mile train that I took this morning.

RE: RE: RE: RE: RE: 33cc homelite
 

av8tor1977,

I called Montana Rail Link this morning and found out they do indeed use a radio contol system. They use the "BeltPack". I did a search on the net and found some info at www.canac.com. Look under "BeltPack locomotive remote control".

I'm not sure if this system will produce interference with my radio, I'm still looking into it.

Ron

RE: RE: RE: RE: RE: 33cc homelite
 

Here's an update on the "BELTPACK",

I e-mailed the CANAC co. asking them if their locomotive remote control system would create interference with my 72.430 MHz R/C radio. Here is the reply;

"The frequencies will not interfere with each other so you should not have any problems."

I'm surprised CANAC replied to my query so quickly, that was very nice..

Ron

RE: RE: RE: RE: RE: 33cc homelite
 

Ron---What frequencies did Canac say they operated on??? Also---how in the world do you all upload a photo. I think I know but may be missing it also. Thanks Hooker53

RE: RE: RE: RE: RE: 33cc homelite
 

hooker53,

That one sentence was all the info CANAC gave me in their reply. They probably would not give me their frequencies if I asked them, you know, security reasons?
I'm not very computer savvy, my wife taught me what little I know. I select "Upload Images" and retrieve them from my computers files. After they upload I click on "OK" and the computer does the rest. Keep in mind that I have a digital camera, I can take pic's and then immediately transfer them to the computer and in minutes post them on RCU.

Maybe somebody will chime in and help out?

Ron

RE: RE: RE: RE: RE: 33cc homelite
 

Ron,

Your receiver worked OK in the Stinson and for a while in the Hawk, so something must have happened. Is that receiver a dual-conversion one? They are supposed to reject harmonic frequencies.

Hooker,

You have to hit the "REPLY" button to get the image upload option. You have to resize your images so they will be accepted. The ones that come right off the digital camera are huge files.

Jim

RE: RE: RE: RE: RE: 33cc homelite
 

Boy---sure would be good if you could find someone with a Frequency counter and measure what they are transmitting on. Just for your info that is. If it's close to the one you are using you could be catching some intermod. Thanks on the photo help now lets see if it works. I tried to change the Res on oine and may be messed up. If it makes it this will be like the one I'm scaling up. Thanks

RE: RE: RE: RE: RE: 33cc homelite
 

Well your'e starting to get the hang of it, hooker53, I see an airplane!:D Yeah, I'm curious on what kind of signals they are sending out too.

Jim, the receiver is the R700 job, I'm not sure if it's dual conversion (What does that mean?) or not. Like you said, I got a bunch of flights in on the Stinson and the Hawk B-4 it started acting up. I flew the LT-25 4 more times this morning and it worked perfect.

The only thing I can think of is that something in the Hawk was vibrating just right to cause some sort of interference.

I plan on installing the 33cc homelite in a BUSA D8 this summer and I want to upgrade to a better radio anyhow.

Ron

RE: RE: RE: RE: RE: 33cc homelite
 

I'm not sure how it works but somehow it processes the signal twice and refines what the receiver sees. All the Hitec receivers are dual-conversion and the newer Futabas are. The older Futabas are single-conversion. I don't know about JRs.

Jim

RE: RE: RE: RE: RE: 33cc homelite
 

I imagine that CANAC is very careful that their control in a 100 ton locomotive is not on the same freq as a model. You don't want to lose your model to radio interference, they feel the same way about their train.

RE: RE: RE: RE: RE: 33cc homelite
 

Yeah, I thought about that too, but av8tor1977 said he has had problems near this system, so I guess the jury is still out.

Jim, I found a muffler that might fit your ME110 cowl at Dons Hobby Shop,www.donshobbyshop.com in the accessory section. It's made by J&A mufflers. I don't know if it will work for the Homelite or not. I do know that the Homelites bolt spacing is the same as a 31cc Ryobi, and they are not far apart, cc wise.

Ron

RE: RE: RE: RE: RE: 33cc homelite
 

Good evening everyone. TKG---you don't have to be on the same Freqency to catch a harmonic of there friquency. Also---they are putting out much more effective radiated power than we are. Now can someone tell me??? Do you use the gaskets in between the head and the case of the 25/30/33 cc homelites or just blue gasket goop?? Thanks hooker53

RE: RE: RE: RE: RE: 33cc homelite
 

Hooker53,

I used just a smear of black 100% silicone (gasket sealant) on mine, worked fine.

Ron

RE: RE: RE: RE: RE: 33cc homelite
 

Right---- I picked up on that when taking a Quadra 41 apart the other day and putting it back together. The last 30 cc homelite I did I just milled the primary part of the case down and it hides most of the gasket. I will start another 25 cc sometimes this week and I think I will take secondary web and all out and see how it looks after I buff it out. When I do this it would look a lot nicer to use the 100% high heat silicon

RE: RE: RE: RE: RE: 33cc homelite
 

The 3rd and 5th harmonics from the railroad frequency would be the ones to get you too but the original frequency is the strongest.

Enjoy,

Jim

RE: RE: RE: RE: RE: 33cc homelite
 

are the 33cc homys single or dual ring type.also, would buying a 2 ring piston for my 31cc ryobi be worth it,how much increase in performance and power is there, if you can do this..im putting this in a sopwith triplane, quarter scale,80" span,11lbs without engine.

RE: RE: RE: RE: RE: 33cc homelite
 

Buck, I've got a homie 33cc but havent taken it outa the saw to see how many rings it has yet. Going to a twin ring piston would increase the motors rpm by a few hundred or so. Some would say its worth it some would not. If you want all you can get go for it otherwise enjoy it as is (which is not bad at all) and save the money for scale wheels or something. Piper
