RE: Brillelli 25GT on CMP Spitfire
We got the extra at an auction. Actually Mark bought it to test the 25 on. It is a Carl Goldgerg 1.20 size. I think it was built from a kit. It is pretty light. No all up weight yet. No time to get it ready until after Toledo.

RE: Brillelli 25GT on CMP Spitfire
On the Giles 202 there is a hole in the engine box where the fuel tank sticks out the front. Once you bolt the 25cc GT engine on, how would you route the fuel lines since the engine would block everything? If some sort of stand-off mount is used to set the engine away from the engine box and give the fuel lines access to the engine, do you think the distance from the engine box to the backplate would still be ok to mount the cowl correctly?

I plan on mounting the 25GT to the engine box and route the fuel lines out the side of the engine box. Remember these gas engines have a carb that has a pump on them so the location of the fuel tank is not as critical as with glow. The fuel tank will be moved about 2" toward the rear and supported with form rubber. These gas engines are just about 1" longer than the 160 glow engines that most pepole use on this plane and even with ei the gas engine will be a little heavier than the glow so mounting the engine like this will help keep the CG. This will also help with insatlling the cowl.
Thanks

That sounds like a plan to me. What about moving the fuel tank on the CG??? Is there any problem with gas engines with the fuel tank being so far away from the engine?

Moving the fuel tank back 2" ill not have any affect on the way the engine runs. It will help with keeping the CG location which at this time I have no idea how far back from the leading edge it is and the directions don't give you a glue. I plan on using the main wing spar as a location for the cg to start with. I also have no idea of the throws on the aileron, rudder and elevator. I have a 4 star 60 that is almost the same size as the CMP Giles-202 and I plan on using the control throws for it as a good staring place.

RE: Brillelli 25GT on CMP Spitfire
I got the chance to go out and do the final pre-check on it this morning. Too windy for a maiden flight.
I spent a full two hours going over everything plus running a tank of fuel thru the Brillelli . Even after swapping from the 16oz tank to this 12oz I'm guessing I'll get a 15 to 20 min flight. I charged the 3 batteries and tested the retracts several times. Tweaked the needles until I was happy with the transistion throughout the throttle range. Checked for vibration problems and found a few. First off I really think I better swap these nylon/plastic type control horns for some good quality alum jobs. All other nuts and bolts seem to be holding well and the cowling didn't get loose either. My muffler, velocity stack and custom fins are holding tight. (I used red LockTite on these items.) Fuel dot pops out of it's holder during runs but I bet someone here will share a tip for that. I have a feeling this plane is going to be fast. It was fast before with only a 91FX strapped to it. Standing behind this thing while it sits running at 1/4 throttle on the test bed, the prop wash is awesome.
Jim,,, since you already have one of these engines on another plane I'm sure you've builtup your new Giles 202 for the extra vibration of the gas engine. This will be my first and don't ask me why I had to try out gasoline power for the first time on a warbird. LOL !!! But I figured if I survived this Spitfire ordeal,,, I'd be easily ready for an Extra300 or something like that.
Scott,,, how was Toledo ?

Everything sounds great and I cannot wait to see this bird in the air with that 25GT engine in it. I have my Giles-202 ready, but I have to work this weekend so It will be a couple of more days before I get a maiden flight in. I will post some video when I do. I beefed up the engine box with some basswood tristock and gorilla glue. She should be just right for this engine.

I have an idea jstanton. If you take your Giles 202 with you to work and say around 10:00 sneak out to the parking lot and fire that baby up and get a few good laps in you could have the video posted by 11:00. Oh, don't forget to take the cleaning lady with you so she can shoot the video .

I would love to do that, but I work in Memphis and there is not a lot of room around here and I do need room to roam. I do not do the 3d thing so I need my space to fly and I just don't have it anywhere near by my work place unless I fly electric's. So I will have to be patience until I can get to the filed. I will be testing the engine before I go and i'll let you know haoe she trest out.

Hi Captn,
The name comes from myself and Marks last names. Scott Ellingson, and Mark Brill. It was either Ellibrill, or Brillelli. Ellibrill sounded like an allergy medication, so we went with Brillelli.

Have you flown your Spitfire yet? I was wondering how your engine runs inside the cowl? Mine is not able to hold a good idle inside the cowl and Scott told me what I needed to do, so I thouhgt I would check with you and see how yours is running. What RPM readings are you getting on your 25GT w/ei. I am getting 8300RPM with a APC 17x6 prop.

RE: Brillelli 25GT on CMP Spitfire
Jim, , haven't flown the Spit yet. Been windy here and as you may know we had a tornado or two pass by close last night. It hit a local airport and did some damage. I watched the storm pass and kept an eye on the local news plus saw the footage again today on several national stations, CNN, NBC, etc. Our channel-9 heli guy , Mason Dunn is an extremely good pilot and was able to capture some killer footage closeup. He runs a HD camera which is mounted underneath the copter on a turret. He really zoomed in on a Sukhoi parked near the damaged hangers.
Anyway,,, last tach I did was 8600rpm with a 17x6 APC after I wacked about 1/2" from the muffler and started running Amsoil Saber at the required 50:1 mix using premium unleaded. Will idle nice and slow all day. (Or until you run the tank dry.) Did that this evening before dinner. Also went with the NJK R7 type plug.
The engine runs nice and cool under the cowling. But then again I've hacked the crapola outta the cowl to fit it in. The velocity stack sticks thru the hole once occupied by an OS-91FX and then a ST-G-2300 cylinder head. And I cut away the muffler area as well. Leaving the muffler covered completely inside the cowl can trap alot of heat on these gassers.

I heard about the Tornado in your area the other day and I am glad to see you are alright. I must have been a little exsiting at the time. We had a couple of Tornado watches last night here also.
I am glad to see you are getting 8600RPM out of yours. Mine is turning 8300RPM right now with the same prop and she is still not broke in. My cowl covers the entire engine except the venturi stack and muffler so I ask Scott about this and he suggested a mode to the daiphragn plate. I made this mode so know I am going to the field tomorrow and see how is wotks.

I still get a tiny bit of black oil waste from the pipe. Scott say's this will go away after it's had a few gallons ran thru it.
I wish I had a vid camera to show you the first flight. A buddy has one but he's out of town alot so I might just have to write the post report. I'm really itching to fly this thing. Being a Spitfire I don't really need to worry about unlimited vertical, but I do hope for plenty of low-end torque for takeoffs and landings. The plane is fast regardless of what engine you put on it. (Within reason of course.) I'm sure the 25cc will perform fine in the speed area.
Jim,,, your touch and go takeoffs looked effortless on your last vid. The GT25 must have plenty of thrust for a 10 to 13LB plane. Correct ?
P.S. Thank you for the concern over the tornadoes. I hope we and our planes will survive another season of these cyclones.

RE: Brillelli 25GT on CMP Spitfire
Wind died down and the sun came out so I hauled the Spitfire out to the field. A friend was out flying and helped me with the range check. All was good until I started the engine and throttled up to about taxi speed on the throttle. Ailerons glitched. Had been doing prior tests with fuse (elev, rudder only) guess I head back to the drawing board and start the task of trial and error.

Sorry to hear you had a glitch at the field with your ailerons. I was hoping to here how will that spitfire fly's with the Brillelli 25Gt w/ei in it. Did she seam to have the power your where hoping for on your Taxi test? Mine has very nice thrust at low speed for doing touch and goes, but with the 17x6 prop she does not have a lot of air speed. I am no a seep demon anyway I kind of like a plane that fly's real stable and the Giles is just that.
Let us know when you have her ready to fly again.

RE: Brillelli 25GT on CMP Spitfire
What prop do you think would give you more speed ? Maybe a 16x8 or a 17x10 ?
Did you figure out your cowling/idle problem yet ?
Maybe I should have described my throttle speed better. I taxied the plane weeks ago in the driveway a little to get my wheel toe-in correct on the retracts. But today we found the glitch during a throttle setting above idle but below 1/2 throttle sitting in the tail stand.
First thing I'll do is move the antenna. Then on from there. You know the routine.[

RE: Brillelli 25GT on CMP Spitfire
Ok,, found the culprit tonight. A bad aileron extension from the RX at certain vibrations was causing the glitch. I did several other tried and true RFI cures and fixes while I had it apart as I was narrowing down the list of suspected causes. So it wasn't all bad after all. Better safe than sorry,,, yet as you know we can have the sorry happen anytime to anyone .
Next decent day I'll try it again.

Glad to here you found the problem. Now we are waiting to here about the maiden flight report. Take some video if you can. All of us love to watch these nice birds fly.
I did modify the carb. diaphragm plate like Scott suggested and that did fix the idle issue. She runs great now with the cowl on and looks really cool in the air. I do have to fix the landing gear though. I had a little hard bounce and the right landing gear split. I am trying to repair it with a fiberglass repair kit, I think it will work and even be stronger.
The engine is now getting over 8400RPM now and that little extra is making a big difference in how she flys.
Good Luck with yours and keep use posted when you go back to the filed.
