ok guys....as you can see i now have my engine. the 2 things that i noticed after i unpacked everything was, firstly...the cdi unit. its now in a nice shiny box. secondly...those little blue standoffs....lovely blue annodising.. works well against the red cylinder.

i have found one thing so far after visually inspecting every last inch of this engine. guys can you all check where the locating dowels are on the crankcase for cracks. one of mine IS cracked...its cracked on the carb side. it may be a problem with leaking etc...but i will still run it and see if it does.

i temporarily assembled the ignition system with a 800mah 4.8v battery. WOW...it gives out a nice fat blue spark...you will hafta be VERY careful with this ignition system as even the slightest movement of the magnet past the pickup yeilds a great fat blue spark....yes it WILL jump a 1/2 inch gap EASILY.

this engine has 1 compression ring on the piston so it has less drag than if it had 2 rings...much better for power and should have a faster transition from idle to full noise.

speaking of throttle response....the ever reliable walbro carb adorns this engine. its a wt version of perhaps the most well know carb in the world. its a diaphragm type carb with a fuel pump as well so its a "set and forget" carb in most cases.

its interesting to note that this engine uses a 10mm spark plug. most other engine ive seen of this capacity use a 12 or 14mm plug. this 10mm plug appears to be a resistor type plug...handy for reducing the ignition noise asociated with spark ignition engines.

stay tuned.....more to come

Craig you lucky dude, you received your engine B4 me. Just checked EMS tracking and mine was delivered at 10:15 but I am at work. Will run home at lunch time to pick it up.

Should havve more pictures and initial inspection report this evening.

Stay tuned as will also fire it up tonight on test stand to see how easy it starts.

Regards - Jon

Hey BossHoss, you & Craig received your engines B4 me Mine was just delivered this morning so will run home to get it at lunch time. (no wife to take pictures 4 me)

Thats great airplane BossHoss. I have one also but chose to put mine in the Sea Gull Laser instead of the Super Star as it likes to snap low & slow.

Will post pics & inspection report as well as fire it up tonight.

Regards - Jon

the cdi unit is in a chrome coated plastic case. the case is in 2 parts held together with 4 screws. ive had the lid off to see inside. the electronics are "potted" with black compound with a green flap of plastic to protect the cdi coil. there appears to be no metal shielding inside this unit. so im unsure as yet wheather it will cause radio gear problems. the plug lead braid goes all the way into the unit but unsure if it is connected electrically at this end.

My GF26I arrived today in a brown paper box. Upon opening the box found a white box inside containing the GF26I engine, muffler, ignition module,spark plug, spark plug wrench, hex wrench, and blue anodized stand offs complete with allen bolts and blind nuts., all inside a form fitting styrofoam packing .

This is excellent packaging folks as I have friends who ordered engines from offshore and received them in the regular engine box with engine wrapped in bubble wrap and the other parts thrown in with some peanut like foan pieces. End result was dented mufflers and bent exhaust tubes.

So CHEERS for the packaging.

Next I removed everything from the styrofoam inner packing. First thing I noticed was faint smell of gasoline. Looked at plug and it had been run (brown) looked at the piston dome same thing. Also marks on the mounting ears. So I know the factory ran this engine B4 shipping. This hopefully means the needles are adjusted close to normal running setting.

The fit and finish look very nice. The crank case is low volume type made from castings with a satin bead blasted type finish. The head/cylinder is neatly powder coated in bright red. The ignition sensor is mounted to the front of he crank case snout with 2 machine screws allowing some timing adjustment. The muffler is the side dump stlye bead blasted aluminum with shiny satin finish and is internally supported to prevent crushing and has two hardened allen bolts and gasket. The ignition module has a couple nice features with mounting tabs with holes and clips on the side to adjust the length of the HT lead and battery and sensonr leads. These also double as strain reliefs. The aluminum stand off are a nice blue anodized finish complete with hardened allen bolts and mating blind nuts. Also included was a hex wrench to fit the allen bolts and a sparkplug wrench. NO WRITTEN INSTRUCTIONS OF ANY KIND could be found in the box.

So CHEERS for the appearance, fit and general quality. and JEERS for the missing or lacking instructions.

Tested the ignition module with a 600 Ma flight Futaba flight pack and a 2100Ma ignition pack. Both operated the ignition with a fat blue spark. Upon plugging and unplugging the battery pack the heat shrink slid back ffrom the connector on the ignition module and found the battery lead is shielded ( one inner conductor ans outer braid). So I slid back the sensor lead heat shrink and found it was also shilelded (2 inner conductors and outer braid. This shielded cable has a very slippery outer cover possibly Teflon??

So CHEERS for the ignition module making HOT Spark and shielded leads,
and JEERS for the heat shrink sliding off the connectos (will fix with a couple tiny nylon tie wraps to keep heat shrink from sliding)

Next step is to mount this cute puppy and fire it up. see picturs of the above posted below

There is some discussion whether the ignition module is a rebranded Rcexl or something else.

In the previous post I showed a picture of the CRRC module and the Rcexl side by side. . You can see they are they are physically different. The plug caps are made from different materials, the inner insulator is made from different materials and the battery and sensor leads on the CRRC module is made from shielded cable .

The CRRC module has wire clips molded onto the sides to adjust the length of cable by clipping to the side of the module.

Both modules have a chrome like finish. Both module produce a nice fat blue spark.

just an update guys as to what im doing.....i have now got 2 props to try...an APC 16x8 and a Master Airscrew 16x8

will mount the engine over the weekend in my old test rig as i STILL haven't finished my new one!!

photos coming soon

cheers

something i've just discovered with this engine. i put the spark plug in the hole and tightened it up. as i turned the engine over by hand i noticed a noise. it appears to be a leaking front shaft seal in the crankcase housing. this also happened in my big 45 cc engine. i replaced the seal and cured the problem.

just wanting the rest of you to know about the problem as well as the factory.

cheers

lol.....and no i havent replaced the seal in this new 26 cc engine....only my 45 cc engine.

I have my engine mounted, I was not going to try an APC or MAsterAirscrew.

For different reasons. First, the APC is heavy and the MA is ineffecient and prop hub breakage is well known.

I am ordering Xoars, I will test fire but not fly with the APC.

I have a series of pics and a drill diagram, for mounting the engine, that I made.

I reinforced my firewall and retro-fitted from a YS1.10 . Yes, this is going in my Extreme Flight Yak-54 68". I decided it was the best test for it, the plane is built, and there are many copies of this great plane out there now...CG,NP,Seagull, QQ, etc..... I do want to use a tuned pipe eventually , to really wake it up, but the first gallon or so will be on the stock muffler.

My motor seal seems fine, but, alas, I am nearly deaf from playing guitar in a rock and roll band for many years, and cannot hear little noises...........
