How many mah will the ign use? If I wanted to use an a123 1100 to power the plane and ign, with say 4-3010 servos and a Tech-Aero Ibec in a super sporster 60. how many 10 min flights would I get? Just trying to figure this out and keep the plane as light as possible.

That's what I wanted to hear. Thank You I usually only get 4 flights per plane when I go to the field. ( take like 3-6 planes ) so I should be good.

The Max battery drain on the ignition is 455mah at WOT (roughly 13,000 rpm). Typical throttle management, TO's and landings will net you about 325mah per hour on the ignition. Each airplane is different as to the servo choices, etc so you'll have to add the radio system amp draw to these numbers.

I broke the engine in on the ground in the plane and ran 12 tanks through it with an average run of about 25 minutes/tank. On the ignition there is a 2 cell lipo and it was down to 30% (about 3.78v/cell) at the end starting out fully charged(4.2v/cell) and it was about 20 degrees outside.
The receiver battery was just operating the throttle so I can't be of much help there. It is a 5 cell NiMh and at the end it was at 6.5 volts starting out at 7.1volts.
If I ever get the muffler manifold extension(Thanks Horizon !) I'll be able to flt it !

FlatSpin,
This maybe a redundent question, you are using a Tech Aero IBEC? If so how is it working with this engine. I have this same IBEC and am thnking of using it on my Evo. Thanks, Jim.

Youtube video for the Meridian is now online, which was shot entirely with the 10GX engine.

Dave,
Thanks for the video, this is a great size for many who want a gasoline airplane at a great price. I know that I'm down sizing to 20cc and now 10cc. Jim

I just saw the video, and was interested to see what the airframe looked like after a flight. I got a screen capture and came here to announce the video was up but I got beat to it by Dave! 
Anyway, we can all look forward to the engines black goo really cleaning up its act after awhile!

It's likely the most tested device of its kind on the market. Ed and I used at least 10 different radios early in its development to checkrange lossdue RFI, and Ed used at least 10 more by himself when evaluating the IBEC's filtering and optical isolation.
I use the IBEC on 30-60cc gas engines, Ed uses it on his YS 4 strokes that are run on CDI. And many IMAC guys are running the unit on much larger engines. It's the same unit for all applications.
Another great thing about it is the weight (around 18 grams) which makes it a cinch for the 10cc or smaller powerplants. I set mine up to arm on the retract switch...very safe and convenient

Matt is right on! I really like the Tech Aero IBEC. Light weight, simple to use, and reliable. And I really like the super bright LED that can easily been seen in flight.

Unless you want to fly a lot without recharging the lighter 1300 LIFE battery from Tower (for example) wold be fine also.
Yes flatspin, anything further testing with the mac's muffler would be interesting. Seems like it should work at least as well as that Tower muffler on the guy's 9cc... ?

There is a product called the Twinn-sync that will automatically keep both engines at the same rpm and if one quits it will immediately reduce the throttle of the other to idle .

The important thing with twins is not keeping them in perfect synchronization, it's in keeping them both running. That's what's great about gas/petrol power - they are typically much more reliable than glow engines.

yea its this unit https://www.troybuiltmodels.com/items/WRCTWINSYNC.html check it out

Twin engine planes do not need to have their engines "synchronized". Adjust each engine to run good and reliable then go fly it. it'll work great and be very reliable. If one engine is weaker than the other, no big deal, it is just a little aileron trim, maybe a touch of rudder too. If you try to synchronize the engines up with each other, you wind up with one engine too lean and one engine too rich, a lousy combination.
If you do have a engine flame out in the air, cut throttle and land the airplane right away, treat it like a dead stick landing. Thus you'll never wind up crashing the plane. You aren't in the plane flying it yourself, so you really do not know which engine quit, nor do you have a feel for how much rudder to use to compensate either. If you try to fly it on one engine, it will usually snaproll on you then.

Yippee! I've finished the Seagull Funfly3D fitted with the Evo 10cc and am quite happy with the build. The engine dropped right in without issues for an inverted installation. The build went without any surprises or problems. There is adequate space inside that nothing had to be shoe horned. The listed weight was 5.1 - 5.7 lbs and finished weight using the 10c was 5lbs 13 oz but that is with a 2100 mah battery and the plan is to drop back to a 1400 so should reduce weight by the one ounce over the published weight. And... it balances right on the prescribed point so no additional weight is needed.
If this thing flies as good as it went together, I'm happy. At 840 sq in (wing loading 15.7 oz sq ft) this airframe is only 40 sq in less than the Meridian but weighs thirty six ounces less than a full weight Meridian and just maybe will be in the unlimited vertical zone of the Evo 10cc. If my prediction of thrust of the Evo 10cc between 5.25 - 6.25 proves true, the Funfly3d is right in the middle so has a chance.

Some prop experimenting will be in order after the break in. Will try to locate the suggested 12.25 x 3.75 but I'm wondering if this engine indeed does have a wide power band that goes lower rpms than typical to glow, I'd like to keep rpms on the lower side to reduce noise. Did I recall one of HH guys commenting that after break in it, it could be loaded a bit heavier to reduce rpms while still making good power and not overheating?
I actually bought a 14x4 funfly prop with the expectation of shortening it to around a 13x4 if it loads too heavy.

Pete or anyone,
I have always use wood props on my larger engines, but would an APC type prop be better for this size engine or does it matter? Jim
