The Liner is OK nut the piston is scored. Trying to get one now before I can't. Also could do with bearings. As I see it might as well replace these too if I'm taking it all apart. Dennis

Hello All, Does anyone know how I can soften/disolve an epoxy resin joint. I need to remove part of a wing that has been joined using epoxy. Also, On the same subject How do I unglue a PVA joint without submerging the job in water for ages? Hope someone can assist. Dennis

I managed to get some drawings of the Mk2 & 3 motors and the MK3 has the words "IRVINE" vertically written on the crankcase and the screws for the exhaust go through the case into the exhaust pipe. On the MK2 (ABC) "IRVINE" is written directly below the cylinder barrel and the screws do not pass through the crankcase. So I believe my motor is a MK2. Do you agree? Dennis

Thanks folks for this. Been talking to Wheekspin Models and they contacted the inporters of Irvine engines and they say as long as its an "ABC" then most parts will fit. So Im going to order a new piston & liner and see what happens. Once again Thanks folks. Dennis

Hello, Recently I was given an old Irvine 46 motor. I need to get some parts for it but I’m not sure what mark it is. I do know that it was made in England, the Allen screws that hold the silencer on need a 1/8” Allen key and the body is not RED. Can anyone tell me how I find out it mark No. So I can order the correct parts. Many Thanks Dennis Mulhair

Thanks Steve, I have PM'd Ian and waiting for his reply. Dennis

Hello, I have just acquired a rather dilapidated T180. What are the chances of getting a copy of the building instructions and wing plans? I have tried the link to IanR but it no longer works. Hope someone can help Dennis

Hi Mike, Can you confirm please that the latest version of the D8/D4 software is 110420. I take it this will work with the new FRSky XJT software XJT_ACCST.2.1.0 Regards Dennis

Is anyone interested in buying a wattmeter as I have one going spare? Dennis

Then again I suppose if I was measuring in the real world using say a 1 cell LIPO and an actual motor and esc the readings would make more sense. I will try this tomorrow. Dennis

Hi Chris, so if the value is that at "Max Power" maybe the Min Volts & Max amps be relabelled to MPvolts & MPamps? At the moment its a bit confusing. Dennis

Hi Chris, could you explain an anomaly I have come across. I am running the units on V4 software and have noticed the “Min Volts” is recording what appears to be the maximum voltage of the cell. I was expecting the cell voltage to drop in use and with a volt meter across it it does, but the Wattmeter is still recording the higher voltage that was there at switch on. The “volts” value faithfully follows the state of the voltage on the cell. I replaced the 1 cell with a power supply and the unit was the same. When I lowered the voltage on the supply the wattmeter only recorded the higher initial voltage in “Min Volts”, but if I increase the voltage (something that would not happen in the real world) the “Min Volts” alters to reflect this increase. Are we recording the Max voltage of the cell, and so should the labelling change to “Max Volts”? Regards Dennis

Works well and accurate.
