Here are a couple shots of my nose gear install from earlier in thread

The servo is just glued into the opening beside the leg. The brass steering arm is home made with a wheel collar soldered to a plate. The leg is held straight with that thin brass wire that runs up the front of the leg. It has a 90 degree bend that pokes into a hole drilled into the retract bearing block.
If you are wondering about the legs, they are Hobby Topgun Mig 15 legs that have been modified to be about 1" shorter and strengthened.
Cheers

cheers eric,i have an idea now of how to tackle the problem,it's the same idea you went for that i'm guna use for reinforcing that front retract except that there will also be a ply plate underneathwith foam in between
cheers

PW-RC has the retract units, with metal trunions AND you can get the pre-assembled version with steering arm etc ready to go!! All for just $1 more....
So even though HobbyKing are a bit cheaper, they don't have those versions (metal trunion or steering), so PW-RC wins..... (for the retracts)

http://www.pw-rc.com/product_info.ph...c2db989cab8d6d

I find those steering versions (all sizes) have steering arms that are too long, but you can just cut it shorter, drill a new hole and thread the wire rod back into that new hole just fine.

Advice please!

Hi all!
Im seriously tempted to buy this F-100, but the bigger scale is a bit daunting. Im used to 4 cell 70mm fan set ups, so learning the good 90mm set ups is all new to me. Ill be using the Het fan and was thinking either the Typhoon 700-68 2250KV on 6 cell, or the Typhoon 700-68 1200KV on 8 cell. Can anyone advise me on the pros and cons, power and amps pulled, and generally the performance i could expect from these powerplants in this airframe?
P.S
I am planning on hand launching or taking off on the belly tanks.
Thanks!

Sniper,

Several comments (some serious...):

1. You CAN put a 70mm 4S power system in this plane. Only if you want to keep limit its performance to taxiing...

2. Hand launching? By the time you will have it built, it would weigh 8+ lb. Can you hand launch that?... If you are capable of launching an 8+ lb plane (bringing it probably to 60+ mph--go for it. If not--you may want to take off the ground using wheel....

3. This is a great plane. I enjoyed the first three flights, and am now seriously upgrading it. You'll see pictures. First time I flew a 90mm plane I was nervous, but they are more stable than the 70mm/lighter planes, and just fly great.

4. I love the HET setup. I use the HET 9305v2 (700 type) fan with the HET 700-68-2250 on 6S. One thing to keep in mind, though, is that this takes 140A (and delivers 2,700-2,800W). If I had to do it again, I might have chosen the 700-68-2100. I don't know. If you want to fly on 8S, you may want the 700-68-1680 (not 1400kV) for comparable performance.

The plane is pretty big, it's over 5' long...

I've flown it on 4.5lbs of thrust but I had stock LG and I was crazy....

Get the 30usd fan\motor from HK and a 90\100 amp ESC from HK also ....55usd ....on 6s 3000 - 5000mah will scoot the plane pretty good and cheap

a 1500 kv motor works great with the Jet Fan 90mm @ 2400-2500 watts at 83-85 amps.

Math shows that it's on 8S. Wouldn't you go with 1680kv?

not with a high blade count fan ,this set up is easy on the batts ...so it might be a hotter set up and could work with a 100 amp esc ...im using a CC85HV so 1500 works for me.

Thanks for the helpful information, and the sarcastic information too!
I didnt actually mean i wanted to put a 70mm 4 cell system in this plane. I just dont know much about the 90mm set ups.
Unfortunatley, i havent got a nice long tarmac runway for retracts, and to fly this beautiful plane with wheels hanging down would be blasphemus! Several people here have proved you can hand launch the the F-100 with the lighter set ups. So i guess its one reason im looking at a powerful 6 cell powerplant.
You say you love the HET 9305v2 (700 type) fan with the HET 700-68-2250 on 6S, but would then choose a lower kv motor if you could do it again? Is this because it pulls insane amps, or its just not as powerful as other 6 cell motors?

This plane has become a little tricky to find in the shops in England, as it seems they have stopped distributing them here. There are couple of the eps versions but no epo. Even Hobbyking have run out. I presume most of you pilots here have the epo variant? Is the eps version the real cheap and nasty polystyrene foam, or is it anygood?
Thanks again!!

1. Yes, life is not worth living if you don't have a sense of humor...
2. Yes, the 140A is somewhat scary, and I believe this plane can use 2,500W (or even 2,000W), which means the 2100kv would be good enough. Not that it's not powerful. This setup does give me 2,700-2,800W. BTW--one way to increase power (and dynamic, in-flight thrust) is to have a smaller thrust tube exit diameter (75-80% of the FSA).
3. I bought mine from HobbyKing when they had 2 left in stock, and within a week or so I saw that the last one was gone. So, sorry about that...

Check out rc castle as they had the epo version very reasonable. They shipped mine to Canada in about 2 weeks and other orders made were good as well.
Cheers

More progress. I'm uploading this post now as the main wing is drying from StyroSpray. I think I did a reasonable job this time... I have the afterburner and nozzle now completely in place.
