Thread: The great i.c. / electric finger chopping debate
18/06/2020 17:23:52

I’ve found it’s never the engine that gets the fingers, it’s always the prop.

Whenever Mrs C or another is helping, communication is key. I say “ignition live” or “ clear”...anything to warn and remind myself

Hi chaps, Thanks for all the replies. sounds like I need a 46 at least then! The 65 has been going for many years, and was very well used when it came to me in the first place (along with the airframe) - and it always started and run fine. Now it has developed a noise like a handful of gravel or two rattling around inside after cutting on me a couple of times. I don't have a lot of spare money at the moment so was hoping to utilise what I have to keep her in the air until things improve. I will keep an eye on ebay and see what comes up.

cheers, Simon

Take it to bits and see what might be making the noise. If it’s bearings then the replacement cost is a few pounds. If the engine is dead , you can’t break it any more than it is.

Open it up and have a peek.

If you have any, leave to soak in glow fuel for a day or two. If you can remove all the plastic bits,(can’t remember if the mds has a plastic throttle arm). GENTLE heat to free the oily residue

Sadly Sheila Scott`s Comanche was written off when it had to put down in a school playing field just short of the Elstree runway due to engine failure caused by a severe oil leak. My father was the sec at the aero club at the time and i have a number of pics of the stricken aircraft in the field about an hour after it happened. The crew walked away unhurt, i believe the remains are now in a museum in Scotland. Sorry i see i have more or less duplicated what someone else has posted, that will teach me to read the full thread!

John, must ask about the floats. How much difference to the cg do they make? Obviously creating more drag...any flight differences

No you don't because you effectively only have one RX with 16 channels in two little black boxes.

Mine are bound separately. One Rx doing port, the other starboard, with separate batteries and switches. If one battery and Rx fail the plane has still some commands.

I’ve done this with a couple of FrSky fasst Rxs. To be honest, I’ve not tried the fail safe yet, though if you set failsafe independantly on each Rex then it would work. Binding the Rxs was no issue.

Don’t put me under any more pressure than I’m feeling already.....and it’s not finished crying

More nose work done... engine cooling, baffles, entry and exits have been thought about.

After stripping the engine as much as possible of all the plastic parts, have a heat gun and some welding gloves and heat the engine.

Make sure the heat is even over the bearing housings, it will need to get very warm if not hot ....a hair dryer is no good. Once the old oil is smoking well the bearings should drop out. Make a note of which way the crank pin, liner and piston come out as well.

Modelfixings or Simply Bearings are excellent for bearing replacements.

when putting back together, replace the o rings, any fuel tubing and glow plug.

It’s surprising how moving “useful “ weight can reduce the need for ballast.

Was the old ply frame unsuited for the new glazing ? I saw a frame a couple of pages back.

I’ve used clevis links and nylon fishing trace wire. Just a simple job of unclipping everything. The “closed loop “ on the aileron was just black elastic.

No. Don’t forget that the wing struts are!

It doesn’t work. As soon as some load is applied the rod jams in the tube. I placed a loop of string around the rod and pulled about 2kg .

Back to the drawing board
