Name: front retract f100 #1.jpg
Views: 169
Size: 153.0 KB
Description: This is how I mounted my retract I used a trim router and routed out an 1/8" area to mount the ply to ,then drilled it and used epoxy and stuffed tooth picks through the ply to lock it in place I made it bigger to try to spread the load over a greater area to dissapate the load , then mounted my retract tray made from aluminum plate to it . I fly off of dirt fields and I did not want any issues , so far its holding up real well

Whatever you do in the front-- make it light. This plane is nose heavy, and will require tail weight. For every 1oz you put in this long tail, you may need 2oz in the tail...

Which ones are you using?
I would recommend programming maximum throws to as much as your radio will let you (+/- 125% or 150%), and use 6V BEC or battery.

When it comes to servoless retracts the only ones I've found that just work are Eflights , I destroyed the flyfly ones on take off ,Now I'm trying the RC Landers and I'm waiting for a replacement main gear retract from Hobby King , Right out of the box it wont cycle !

Put them on a gear switch and do full throw and they'll work...they don't cycle without full throw both ways.

Rudy,

I don't share some of the comments made earlier that the E-Flite landing gear is the same as manufactured in China somewhere for $7. I went through many gears, from RCLanders, to all kinds of HobbyKing gears. Some (specifically, RCL) are not very cheap, but yet I found nothing built like E-Flite retracts for the size planes we are talking about. You can see the workmanship, and it is better than the others. They don't flutter. They are just made well. I'm sure they cost much less to manufacture than they are charging us. Otherwise--they will not be in business... My last three planes (the H9 P40B, this F100, and the FlyFly L39 that's on its way to me) all have E-Flite 25-46 size landing gear. No problems at all (at least not with the ones already installed...) and you can see how sturdy they are. So I'm with rush1 on this one. I hope this will not spark a philosophical debate that will distract us from the F100 at hand...

The large plastic servoless retracts in my F-100 (4.2kg), F-16 and F/A-18 (both 3kg give or take) are working perfectly with many flights. Enough hard landings to prove to me they can handle the job.
At $8 a piece they are hard to beat. The only drawback is you must rig your own nosewheel steering system. I used 20lb fishing line and it handles well with no slop.
If you use servoless retracts be sure that the gear leg doesn't wedge up tight against the motor/housing. This may prevent the next extension. If this happens, just remove the leg and provide more clearance.

I run my system on 4.8V. Can't speak for 6V setup....
Cheers

I use the same HK retracts as 4 stripe on several models with good luck so far. On my F-100 I use a Life 1800 mah 2s unregulated as the power supply for the retracts and radio gear. many flight and no problems. Oh yeah and quite a few bad landings....

The e-flite retracts are a step above the HK and worth the money if you have it.

Just my 2 cents

I've used the PZ 312 and 514s on 70, 90 and 120 planes...for the price they're pretty decent...

The CS (non PZ etracts) are the same as eflights just not QC'd....the chips on board are the same
