are these a replacement for Eflite EFLG100 ?
 Tank1 1086 points
I know they do them because i have brought a few sets of them but because i'm not at home i can't say for sure if these are the ones i brought for my Eflite/PZ planes,but i have a feeling they are the ones but you really want to make sure first,simple thing would be to find out the measurements of the ones you want to replace them with,sorry this isn't the best answer for you but i hope it might be some what helpful.

I purchased them and installed them in a EFlite Mosquoto but had to use adapter plate supplied so they are an inch higher than original. Would not fit in original position because of frame for screw came out too far. But otherwise work ok. Also had to elongate 2 mounting holes in retract.

Youtube has some good videos with people showing these retracts in use,that way you can clearly see what you need too,just type (Hobbyking Daily-Electric Retracts) in the Youtube search engine and HK's video will pop up and a few others,hope that helps a little.

Hello, Anyone knows where can I find PCB replacement for this retract? I burned them for overvoltage, but the motor works ok. Or Please HK, sell them cheap for DIY fans.
 Tank1 1086 points
I doubt they bother selling them because the price of the retract unit it's self is under $8,so you might as well get another retract unit and have some more spare parts for your next DIY job,well that's what i would do because it won't put a big dent in your wallet.

are these metal trunion?
 Napstr 1308 points
They have a brass pivot so the pin things are rotating around is metal (which is where you screw bolts or grub screws to hold your legs but they would be considered plastic trunnion as the rest is plastic - my opinion is these are better than metal trunion ones as the screws holding the legs are solidly held by the brass so you get a good hold and they are lighter - I have never seen the actual trunion give way on these as it sits flush with the mounting plate - the mounting plate however is what gets mangled on these and the metal trunion ones.

would like to know if this is a good replacement for the Durafly T-28 Trojan retractable nosegear? The main gear retracts have aluminum blocks that the strut goes into...the nose gear is black plastic...I would like to know if that black piece is in there...mine snapped and the nosegear sits on the strut on a collar and an E clip to hold on!.....thanks for any help!

Just installed a set of these on my Starmax 70mm F-5. They look to be perfect for any 70mm EDF & 25 size or 'LIGHT' 40 size prop plane. Specs say upto 2.5kg but I would'nt go above 2kg, a little little less if you fly off grass. The action is smooth, not too quick & overcurrent protection :)
Suit a 3mm strut & uses brass threads where you can screw grub screws to secure the strut. Excellent value for money, I've ordered 3 more for my 70mm F-35.

The problem is a not enough powerful H-bridge in the control device. My two retracts burned out after about 8 or 10 cycles. I opend them and there was a transistor damaged. After I've replaced it it's working fine again. For Me it's easy to repair it but what are doing other modellers?
I suggest that you have the same problem if you smell a bourned out electronic divice.
