On the Jets, EDF + Pushers Forum recently, Easytiger mentioned the new micro air retracts from rc-warbirds. This includes a steerable nose gear and 2 mains, 2mm wire struts, air valve, splitter, mini air tank, air hose, one-way filler valve, mounting equipment. Weight (except air hose) 35 grams, max plane weight 1500 grams.
rc-warbirds also sell mini mechanical retracts.
In addition, 3-bladed and 4-bladed propellers, only one size offered, 236/200mm which is about 9-1/4" x 7-7/8".
Lots of other EDFs, Warbird ARFs, motors, ESCs, batteries, DF units, more.

I used a those style retracts in my PZ Mustang and my new NitroModels P38. Systems work sweet. Saves weight too.

FLAME: Why aren't there more options out there for 3 blades that offer a counter rotating version. I like my models to look accurate.

Can't find the air retracts on the site :(

GG, you went air, correct?

TO Jeff, You're right! They removed the photo from the home page, it was the top left corner picture. Also took them off "accessories" page, they still have .40-60- sized listed and mechanical but no micro air! It's a puzzle to me, if they were sold out they could just say "out of stock". They've been "disappeared"!!

I hate it when that happens :)

Looking at the same plane Glacier Girl is flying (Nitromodels 51" P-38), but it _needs_ retracts (and I'll never own another set of mechanicals!)

4lb model, probably needs 110 degree nose retract.

The units I used were from Larry at SouthEast Models. Not cheap at nearly $300.00, but work very well. Are designed for 5 pound bird.
They are 90 degree units so I had to do some creative installing to get some forward rake on the nose gear. I have a new, heavier nose gear on the way from the same place as the grass soccer field I was using was beating the daylights out of the current one.
Sure beats the heck out of installing retracts, servos, linkages, reducers, etc, and making it all fit. And since they are spring down, they always come down.
You can check with Larry, as he was originally converting GP10's to air, you could buy them built or just buy the kits to do your own. I used these in my Stang. Reach him here. [email protected]

Master Airscrew sell 3 bladed pusher and puller props that should solve the counter rotating problem. I've ordered 2 for a catalina I'm building.
