20-25cc is what I'd target also, The real question was related to the convenience of needle access. I'll solder a brass slot screw head to the needle stub I think, or if enough material, sleeve it with brass/solder, then Dremel cut a screwdriver slot. Then I'll be ready to tweak at every start-up.
Since I bought a used Phoenix earlier this fall, seems every aircraft I own may eventually inherit the name. Recently refitted the Sparrow Hawk .010 foamy with a TD .020, it's ready to go. The Profi racer is ready to go, the Demon .67, a few other things that all needed just a bit of attention and/or ambition to get back into the air. And look what crawled from the ashes this evening - the Squirt rises. And, with a burst of ambition late this evening, some impromptu facial surgery was made to accommodate and .05/.06 mount and a throttled VA MKII. It's another stupid light airframe like the Boomerang, don't recall weighing it but in the 10oz range I think. One ACE panel. Stubby little thing. It flew alright with a Sure Start, but I the engine was erratic in the air. The glide was smooth, flat and gentle - the wing loading is quite modest. The VA should perk it up a bit, and with throttle.. well all the better. I have a nice homemade Fuji clunk tank to feed it, holds about 20cc. Lots for this combo. If Saturday looks respectable (I daren't look) it may be a chilly 1/2A party at the airfield. And some shots of the Boomerang interior. The Rx switch is - presently - a 6" extension with Velcro to stick the connection to the fuse side, Works fine, I want to pull the wing every flight to check the bladder, and it takes about 10 seconds so who needs a switch,
