[Range of AR500 reciever]

Should have added in my previous post that it was not the absolute distances that I was drawing attention to but the comparative distances obtained between the rx tested. IMHO not that great between 'near top of range' to 'park fly'. Of course in model flying use signal path diversity will play its part and those with satalite units will show an advantage.

[Range of AR500 reciever]

Agreed, USA - 200mW ; UK - 100mW. But, half the power will not reduce the distance by anything like 50%. It's a square law relationship, probably only reduce by 20% - 25%.

[50th Anniversary Issue]

Contrary to what it says at the top of this thread - checked in 'Smiffs' LLandudno on the 15th, quote ''Not in till 22nd, 14 on order and no reservations''. Checked in 'Smiffs' Colwyn Bay on the 16th, quote ''Not in till the 30th, 6 on order and no reservations''. I'd send off for it but I think nearly 40% of the cover price for postage is excessive! I've been taking RCM&E since it came out in the 60's and still have all the issues, free plans and specials so I suppose I will make it my objective to get one eventually, but not with that postage.

Escort designs were the subject of a copyright action, 'Bowmans' v 'Galaxy', some time back. Just a little snipet of info, best not to go into to much detail.

[Taking the Petrol Plunge]

I think the original exhaust is best described as an exhaust deflector. I think that the pitts is only slightly better otherwise it's make your own time or go to JE for a custom made item.

[Taking the Petrol Plunge]

Almost forgot about the noise. One of THESE  may help if you have room.

[Taking the Petrol Plunge]

Great stuff!! Looks like its going to be lots of fun in the plane. A few observations:

with no velocity stack on the carb you will get fuel spit back at low revs and although low oil content be sure to fuel proof the inner edge of the hole.

Vibration, use servos with metal gears and have a look HERE

[Taking the Petrol Plunge]

You may wish to consider making a hole through the firewall to allow the carb to breath. From the photo it looks much too close to allow for a sufficiant flow of air.

[Taking the Petrol Plunge]

The new engine looks like one of the new CRRC 26R units. Be very interested to hear how it goes.

[Taking the Petrol Plunge]

Do not have the prop too close to the cowl like in a normal slim cowl installation. The prop will be more efficient if the rear of the prop is up to 1'' away from the radial cowl face. It may look odd on the ground but the further away from the cowl the more efficient up to a point, its all a compromise. It's your call.

[cdi]

You may find the following test proceedures. for RcExel units, useful. I found them on the RCU forum. One of the experienced contributers comment on testing without the plug connected was that if that caused it to fail then the CDI was no good anyway.

''Take an old expendable servo extension and cut off the male plug end, separate the wires, strip a bit of insulation from each of the 3 leads and plug the other end into the sensor lead on the ignition module. Put a good CM-6 plug in the cap, doesn't need to be all the way seated but far enough for the hex of the plug to make contact with the metal shell of the plug cap, plug a fully charged 4 cell battery directly into the ignition. Test for battery voltage at the red and black wires of the test extension you made and plugged into the sensor lead of the module, if there is no voltage replace the module, if there is battery voltage......Short the white and black wires together, every time you break this connection there should be a spark, no or intermittent spark=bad module, has good spark......Remove the test lead and plug the sensor on the engine into the module and turn the engine over, no spark, replace the sensor, good spark.... Remove the spark plug, look down into the plug cap and turn the engine over, if you see spark arcing through the silicone boot to the metal shell, replace the spark plug cap, no visible spark but you hear a snap.....Put a small screw driver into the bottom of the cap, turn the engine over and you should observe spark jumping from the screw driver to the plug cap shell outside of the silicone boot, an arc of about 1/4"-3/8" if it does this there is nothing wrong with the ignition, if you hear an arc but it's not in the cap with the screw driver it could be a problem with the resistor in the cap or the high tension lead where it goes into the cap, replace the plug cap. ''

Hope this may be of some use to anyone.

Regards.

Elmic corporal is for motor control. Still have the 'UK' Rx I built back in '62 when it was published in RCM&E. Unable to check if working as I gave away my 'Windy Kreulen' Tx to Mike Crisp of 'Model Aero Services'. As an aside I have every issue of RCM&E published, duplicates of the early years as well. Some say I'm a sad individual and I should get out more and get a life.

Sorry about the expletives, now deleted! But, I do tend to see red when customers are fobed off and told they will be at a disadvantage when the problem is no fault of thiers.

[DX6i service announcement.]

You are entitlled to your money back from the retailer under the sale of goods act as the item is not fit for purpose (general recall). Do not be fobbed off with the response that the items are too old (trading standards will confirm this). It's the shops problem to get the money back or the goods exchanged from the distributers/manufacturers, then, you can add the extra money to the refund and get what you want.

[2.4ghz compatibiltiy]

Anyone now anything about the 'Jeti' moduls and receivers??????????

[DX6i service announcement.]

No, going to get a 2.4 modul for my Futaba '9C' and keep my '8' for 35. I've never had any probs on 35 in the past approx 20 years. I only got the 6i to go with the mCX as a better alternative to the E-Flight controller and as I am now going petrol, 2.4 might be useful.

[DX6i service announcement.]

Bought mine 9/1/09 and it was faulty, though not at first (thought my senior moments had all joined into one when I could not control my mCX). Horizon were only going to replace the faulty elevator pot. But, as all the pots were from the same batch I was not happy, AFTER ALL WHO KNOWS WHEN ANOTHER POT MAY GO FAULTY! Anyway the model shop (Steve Webs) gave me my money back without question.
