Status: offline 		How do you guys manage the weight up front? We already have two batteries under the turtle deck and 6oz of lead in the tail and it barely balances where Reza and the manual suggest - we are flying ours without a spinner.

What type and size batteries do you have back in the turtle deck? Also, what type and size is your ignition battery? (I'm assumming that the ignition and battery are mounted as per the instructions.)

Sorry I forgot to ask, how are you balancing the plane? Are you using a "Great Planes" type balancer or the "finger tip" method?

Status: offline 		I finished mine with a DA85 and it came in at just over 26lbs. Little more than I hoped for. Do you think it will still have good 3d power at that weight? Motor ran great. Seemed to get pretty hot on the first tank. Never had a DA so I don't know if they usually get hot or not. Any thoughts? I had to mount batteries even with rudder servo to balance.

Status: offline 		I have a nice old 3W 78B2 thats just broken in. I was wondering how it might haul this plane around. Engine weighs close to 7 lbs with the ignition and stock muffler setup. 78B2's have been known to swing a Menz 26-10 around 6000 rpm's. Anyone know what the actual weight of a DA-100 with ignition and stock mufflers weighs for comparison? I've just been thinking about a good home for this engine, and I thought a bipe in this weight range would be a good airframe. Maybe not a 3D rocket ship, but should be enough power for unlimited vertical even at 27 pounds?
Thanks for any insight.

Kevin

Status: offline 		cwhite,

What is your set up? Power system, spinner and ignition battery?
What muffler are you using with your 85?
Did you run a tank on the ground? If so, please refrain to do so. It will damage the engine more than helping it break in. Break-in process should be done while flying on DA.

Thank you,
Reza

Doesn't sound very good for unlimited vertical!

Status: offline 		Oops, I ran one tank on the ground, about 8 oz. at a time. I kept the throttle low and I didn't hold it wide open. I got to maiden the plane today and got a total of 6 flights on her. At 26lbs and motor still new it had great pull out. Plane flew great. Harriers and hovers are fairly solid. Feels like its still a little nose heavy in a hover, nose wants to fall to the side slightly but not too bad. I was comfortable enough to get some pictures taken by a club member with the tail about 1' off of the ground. Blenders and inverted flat spins are great. upright flat spin is not as good as inverted for me. Just touch the rudder for knife edge. Rolling harriers on the first flight, they are very easy with this plane. Mine falls a little when inverted but just slightly. Lands great and looks great on the flight line. Good design guys!

My setup:

DA85
Slimline muffler
Ignition Battery - 4.8v Ellite 2000mah NiMH
Receiver Batteries - (2) 6v Ellite 2000mah NiMH
Receiver - JR R921 with 2 remote recievers
JR8711 for rudder
Hitec HS5955's for elevators and ailerons
Hitec HS5945 for throttle

Chris

Status: offline 		One last question....for you boys that are still flying 72Mhz Radios, you obviously have your receiver mounted in the plane somewhere, where did you run your antenna wire? I have found that the antenna tube mounted in the turtle deck is too short for the entire length of antenna and I would rather have the antenna completely deployed rather than having some of it bundled up inside. What about running it outside the fuse, say down to the bottom and towards the tailwheel, anyone see any issues with this?
