CAP232 Breitling

Sorry Jon, You mentioning the "soft switch" did spur some more thinking on my part. I'll give you both a Thank You. You've now got 48 and Dave B = 28. How's that... :lol:

Something Stupid! If I had read the manual properly (typical man) and looked very carefully at the RX I would've spotted the extra set of terminals marked "soft switch" :S

I am planning on programming the AR9110 to mix channels as follows:

Left aileron = ail, right aileron = gear or aux1, left elevator = elevator, right elevator = aux3, rudder = rudder, throttle = throttle and aux4/trainer switch will be the remote ign kill switch. Obviously the switches on gear, flap will be disabled. This gives me independent sub trims on all surfaces.

Or is there a better way of doing it?

I think I'd use aux 2 for something, otherwise it might feel left out

That should be fine Phil , except 2nd ail should always be in aux1/flap (whatever your radio calls it) channel. As you have JR, there will be a dedicated dual aileron function (10X calls it 'wing type') which you can use to set up differential, flapperons etc. If you use any other channel you would have to set it up manually.

Use the next available aux channel for your second elevator, some of the higher number aux channels can have a noticable lag when mixed to other channels. Easy enough to see this when setting up.

When you are setting up the elevators, it is worth spending some time making sure they track together across their full range, not just at neutral and the end points, when you only do the extremes, you would be surprised how much out they can be at the mid points. Tape a couple of lengths of balsa to the elevators 3-400mm long, with their outer ends together behind the rudder, you will then easily be able to see the tracking. I use a curve mix instead of a standard one, you can then adjust at points throughout the travel. Hope this makes sense.

Thanks for all that info Jon. I was little concerned on some of the mixes because they don't always work as expected. I'll follow your suggestions to the letter. Yes it does makes sense. :lol: Thank you.

Now here is a big quandary and I need experienced advice for the following before committing to purchasing the engine? Judging by H9's old version the aircraft would be around 15.5 to 18lbs depending on equipment.

DLE40 Twin
Total Weight: 3.3 lb (1.50 kg)
RPM Range: 1500-8500
Output: 4.8 hp @ 8500 rpm

I used a scale image of the DLE40T printed on paper, (See images attached) cut it out where it matters, across the cylinders. Without spark plugs it is 180 mm wide. Laid the images inside and outside the cowl and it looks like it will drop in neatly. The only issue would be to not use the stand-offs but a 10mm ply spacer on the firewall to get the prop drive just proud of the cowl. But, is the engine going to be man enough at 4.8hp? I am not going 3D.



DLE55RA
Total Weight: 3.74 (1.7 kg)
RPM Range: 1,500-8,500
Output: 5.5 hp @ 8,500 rpm

The DLE55RA would fit perfectly at 171mm from standoffs to prop driver. Only job here would be to bore the firewall for the carb to partly sit in.

Once holes are drilled then I am committed!

Phil,If it was me i'd go for the DLE 55 nice mid range motor which will serve you well

Thought it was me Phil, Mr Bright always gets all the credit ...........

If you go with the twin you will have to make / source a 2 into 1 header, or run two headers and two exhausts, go with the 55 easier install and more power :evil: Whichever one you get you will need to get another exhaust as the one they come with are useless.

2nd the above opinions, 15-18lbs is too much for a 40cc twin for aeros, I would think absolute max weight for that for any sort of performance would be 13-14lbs, plus as Chris has said all the complication of an exhaust system for it.

My EF Edge is around 19-20lbs and I wasn't happy with a 56.

Go with the 55 as has been said before, your adding a bit of complication of 2 exhausts and extra weight for no real gain .nobody ever complains about too much power but being underpowered gives you real problems. It's easier to throttle back than fly flat out all the time .
