Oh yeah, I guess so. I keep thinking "12 blade" on everything now. So it sounded high RPM for them = 8S to get that.
It flew very good for 2200w area! Though they (midi) are more efficient.

I am looking for 2600w area, 12 blade (Lander fan on 10S 800KV) - it's a big plane!
But I might have to throw in a lower (and cheaper!) 2200W combo to try that first now!!

Yeah, not super fast with my setup but looks nice in the air. My static numbers are 85a, 1900 watts,2.2kg thrust and my auw is 2900g.

I am using those but the eflight 15-25's stock are 3.5mm legs if you have 4mm hardened steel pins then most likely yours have Tams upgraded trunion kit and ya I have Tamstruts on mine

Darned - Front wheel steering!!!

Help! I have been following this thread since it's first days. My F-100 is coming along very slowly. There is always something new to modify! Ha! 12blade CS, rudder, fluted exhaust, flaps, and leading edge slats – the list of clever thing that you all have done is incredible.

My problem is the front wheel steering. I have tried to use the standard pivot and slide method at least 5 different products and 8 different homemade fixes of my own. Every time I think I am ready to slap the front fuselage together - it breaks, starts slipping, the threads pull, etc.... I can build a spaceship for the moon, but darned if I can get this simple linkage to work reliably.

(no – offence to anyone ) I have kept away from the pull-pull linkage because it seems like it will have too much movement and an undesirable way to do it on this F-100. The cheater air hole is right where the servo should be. Lots of cutting up foam, etc..

I have seen the crossing wire with slight off set from center, how is that method holding up for folks? As much as I would like solid linkage, I am ready to get it in the air yet this year! I like to crash like the next guy, but not on the runway.

Pull pull steering is working flawlessly in many of my models including my F100. My servo is mounted off to the side to allow the gear leg to sit beside it retracted.

i second that,i'm using a pull pull steering too and works great on grass so i reckon that on the runway it should too,was a bit tricky to get the right tension but once you've got that sorted it works great

I use the very strong string that Banana Hobbies uses on the LX planes.

1. First tie the string to one end of the servo arm and secure it with CA
2. Next instert the end into the hole on the strut arm, center the wheel and wrap the string around the strut, once is usually fine
3. Take it back out through the other strut arm hole and loop it through the other servo arm.
4. Do not tie it, make sure your radio is on and make the string snug, just loop it back round on itself.
5. With a small amount of CA on the end of an xacto blade, apply some CA to the loop at the servo hole to hold it.
6. Once that is dry tie it off and add CA to both servo holes.
7. Set the model on the ground and adjust the steering, the loop around the strut will allow the string to slide as you adjust the steering.
8. When the steering is adjusted, apply some CA to the strut arm holes to anchor the string.

Been working fine on mine for MANY flights!

Many Thanks for the steering tips

Well thank you all. Who knows my Hun may get bug juice on it yet this year.

Next are the lights, afterburner, and cutting the leading edge! The only thing that I have done that I didn't see here was to modify the stock stabilizer trunions with 4mm bearings front and back. It was easy really drilled out the fracing wall and inserted the bearings with epoxy.

No I've just got the stock eflite legs and am looking for some oleos. I thought they were 4mm? Anyone got any suggestions?

I used strut from SU-35

Ranger Fan, I used the Strut from a SU-35. BH has them under "parts" with front retract for $24 with servo, just the strut for $13(no axles). They are a great height no mods and very sturdy. I think they are 4mm shaft, don't have my caplipers with me. I modified the larger HK servos 44mm to be a front wheel servo and used a 4mm shaft of my own design. Now moving to pull-pull steering.
