My kit is missing 2 wing bolts. (The longer one at the front of the wing). However I am unable to find the parts number for the bolts on horizon website. Can you help? I have some here but they are not long enough.

Thanks a bunch

Bad news is it looks like they are out of stock. Call or Producr Support people and they should be able to find some. They are also used in the Hangar 9 F-22 PTS so tell them that, it may help.

I love this plane. However, everywhere I look, they are out of stock. When do you think you have it in stock again.

Status: offline 		Something else you want to look at and fix is the pilot it comes with. Mine spit the head off the body of the pilot today inside the canopy. there is no glue but what looks like two 4-40 bolts into blind nuts which bolt from the base up into the head. Mine pulled the bolts clean through the base of the body.

I can easily fix it by cutting the hole in the back of the hatch just a tad bigger so I can get the head out (and my hand in there), remove the bolts from the head, sand the base of the pilot where the head attaches to the body and epoxy the head back on

I would suggest before you install it, that you turn the pilot upside down, look up inside and remove the bolts which will allow the head to come off. Then sand the edge of the base and head, use a little epoxy on both pieces, stick the head back on the body and re-attach the bolts. You could probably use thick CA as well. The head is very thin at this point so CA might actually melt this area

Status: offline 		Hey Mike,

I maiden the SUK,
It came in at 23.5lb. with No spinner call it 24lb. with spinner. (that is with 4 12s Li-Po's)
I have all the throws set, CG is @ 7"5/8

12s power was unlimited not much more than 3/4 thottle.
50.2 max volts / 117 amps /5,873 watt's / 244 per LB

10s power was more scale type flying
42 max volts / 98 amps / 4,116 watt's / 171 per LB

the plane few great even in 10mph gust of wind, it tracked nice uplines were straight (the wind was blowing me side ways) It did not need much triming, it slowed down real slow, and landing were smooth even in a cross wind.
I got 2-4min,. flights in. Im charging the batterys now so I will post mAh used.
I need a calm day to really see what it can do.
sorry no pictiures I brought the camera but forgot the memory card .
I'm not going to use a spinner look's real good with out it

THANKS the plane is everything that you said it would be.

It's a keeper / selling the Yak (ha!)

Status: offline 		Anyone had any problems with the engine getting hot? Has anyone put baffels in the front of the cowell to improove cooling efficiancy? I was thinking of installing a thin ply ring in the inside front of the cowell with an opening only in front of the cylinder head like they do on QQ aircraft planes. Is this necessary? I would appreciate any feedback on this matter. Thanks rc3dflyr

Status: offline 		Mine has been perfectly fine temp wise. It's basically built exactly as shown in the book with a couple exceptions. Instead of cutting the stringers out for the hole below the can, I just removed the covering and left the stringers in for some strength and I went with Li-ION's all around and one Smart-Fly SuperReg with 2 JR leads to the receiver and a Smart-Fly 5.2V ignition reg, probably saved 6 to 8 ounce in battery weight

You mean like this?

I made it, but have yet to figure out a way to mount it, get it centered and stay there and not have glue all over the front of it.

It's aircraft light ply with black ultracote.

Status: offline 		I flew mine finally. With the 2 battery packs under the canopy, the ignition pack on the engine firewall, and a zdz80 in the nose, it still seems nose heavy. It flies great though, no coupling when knife edging, doesn't have any bad stall tendencies...I just prefer my birds to be a little on the tailheavy side...I haven't noticed any overheating. I have the bottom back of the cowl open around the pitts muffler and probably a 3 inch hole under the cylinder head. I did cut out the louvers in the cowl, not sure if it really makes a difference in cooling, but it looks cool.....

Status: offline 		Cutting out the louvres in the cowl will make a massive difference to the amount of air sucked out of the inside, the raised lip in front of the louvre creates a negative presure behind it and therefore in effect almost doubles the amount of air extracted for the area of the opening, each subcequent louvre doubles the effect from the one in front, to be rearly effective obviously the air comming in has to be directed through the fins and around the cylinder head otherwise you will get a stagnant area in between the fins.
