Hi Pete,

Finally found some time to get back online

Just curious, why cut the tips off? More scale look?

Hope you had a Merry Christmas and May 2009 be a great year in your household.

Don

If you go the full flying stab route, I wonder if you can buy the mechanicals to the Top Flite Piper or the Cermark F-16 all by themselves.

Hi Don ..Yes thank you we all had a great time over the Christmas period... Yup cut the wing tips just to give it a little more scale look .. still at 48.5" for the span....1.5" more then the F-16

I think I will stick with the stock stab ... I am going to mount the servos for the elevators like the SU27 ...seems it will work will in this case ... I will have lots of Pics when I get going on the fuse.

Cheers

OK ... I have one for you.... With the built in wash out on the wing tips ..1/2" and you install the ailerons.... the top of the ailerons will be flush with the top of the wing at the fuse sides ..BUT at the wing tip it is lower by 1/2" due to the wash out ...Other then trying to warp the aileron to shape what do you guys do?????

I would raise the aileron to make it level with the tip. If the root then looks too high, I would add in a piece of balsa to the top of the fuselage and fair it in to where it looks "normal"

Barring that, I would warp the aileron, but it's easier to fair it in at the fuselage because if the aileron warp relaxes on one side or the other, you'll be left with a plane that is hard to trim in flight roll-wise.

Pete,

I set my flaps "0" at the fuse. The ailerons are lined up to the edge of the flaps. The end of the ailerons are down some at the wingtip. Fly's GREAT!

I think if you try twisting the ailerons you are asking for trouble. {pain in the a##} Built per plans, this plane is AWESOME!!!!

I like your shorter wing idea. Should look more scale.

I might still try the flying stab on the next one, and maybe move the wing back a bit.


Bathroom is done!!!!!!!


Change of plans though. My AKM SU-27 Flanker is next on the board.

I have had the kit for two years. It's time.

Thanks for the input guys As I am not putting the flap on this wing I think what I will do is split the difference at both ends and then sand or add to shape the aileron ...it will be close ....must keep this in mind for the next one....Maybe on th next one build the aileron on the TE when build the wing then cut it off after Hmmmm...

I just finished the wing in time as the retracts Spring Air 101HD just came in the mail today now I can get going on the real work...putting the mains in is going to be a blast to work on.

Tony: Glad to hear the throne room is finished ...now you have a place to study the plans ..... I have built both the MIG29 ( and so has Don ) and the SU27 ....make sure that you use heavier Ply wood for the mains ..they like to snap.... make sure you read through the build thread as I and others put sum hard earned corrections to the plans.. make sure you are on the high end of power for this one ... I have tried the ST .90 ( very low on power but will fly ) and the EVO 1.00 which was about right but heavy. If you need some help let me know.

This one that was done by Jeremy Cesar, of Australia with the mid 3" cut out to move the rudders ahead to the TE ...This is what I have done as well.

OH Boy here we go again .... I am just now putting the formers onto the fuse sides ...have F3 and F5 in place but have now found that the right hand fuse side is so hard it almost will not bend to shape or it will pull the left side out of shape........Hmmmm has anyone used windex to help soften the balsa on fuse sides? I have used it to shape wing skins and fuse skin but not sure it will help shape this thickness of balsa....anyone?

How thick is the fuse side? Windex w/ammonia should help some. It won't hurt it. If the wood is too thick you may have to give it a good soaking which means a long pin down until it dries.

Well after two 30 minute soakings in Windex and drying/bending for 2 24 hour periods I now have the fuse more or less in line with the plan...man the right side 3/16" balsa was hard as you can see in the pic that I had to use the motor mount to clamp to get nose to move.....anyway I have more pics I will post tonight of the nose retract gear, Throttle servo, nose gear servo,and tank install.

Blade47:

Have build around 6 DC (now Juno) kits through the years and find that the kits are well designed and adequate materials supplied. Just finished another Tsunami, did not replace one piece of balsa, usually remake 50-60% of other kits stuff. Only thing I don't like about the tsunami kit is the fuse sides are butt joined in the wing saddle area with 1/16th balsa backing. Seems weak on the surface, but have never had a failure there, and that part of the fuse stayed togeather when stuck into the ground at speed.

If I built another F-18 it would be a Juno kit with air retracts, up and down, and the fakeee jett air scoops eleminated and streemlined where possible. A Webra speed 55 with Jet tuned muffler, or Jet 60LX would be engines of choice. Both idle reliably with tons of power even with speed props. The OS 55 can not run in the same ballpark with either engilne. The airframe will hold 60's or even 90's but the weight penality drops performance in my opinion. Regardless, your going to enjoy flying this puppy, sweeeet. ENJOY

Rmenke: I have found the material in this kit to be all most top notch ... Just the one fuse side and the 3/4" tri stock is very hard ( and heavy ) ... I did get the fuse to bend but I did change out the tri stock. Just finishing up the cockpit /canopy area and then can move on to the fuse sides a tail feathers.

Hi everybody,

I just bought one of these kits from Derek and I must say, the plans are huge! So is the plane. I hope to get started on the build for this plane this week. I have a quick question. I plan on building the plane stock, with flaps and fixed gear. I have a OS 75AX new in the box. I am not looked for super speed on this plane. I am looking for average speed and good aerobatics (would like unlimited vertical but not overly necessary). Would the 75AX with a 13X7 APC or 14x4W be a good choice for overall good performance (decent speed 70 miles/hr max and good manuevers). Looking for opinions, suggestions and advice.

Happy flyng and soft landings!

Being I have not flown this kit and plan on using a AX55 I will differ the question to Bob27 as I think he has had this plane up and of course has tons of knowledge about engine prop combo's ..Bob?

I have a piped Super Tigre .90 on mine. So far I have used 12X8 Zinger, 12X6/10 Zinger, 12X10 Zinger, 12X8 APC, 11X9 APC and 11X10 APC. The 11X10 APC is the best combo tested so far. It looks fast and sounds real fast. My fellow club members think it is 150MPH fast. They don't fly fast stuff, so my planes look real fast to them. It might be going 100-120MPH tops!!! {in a dive} It does sound great on a low pass though. This is a great flying plane. Anyone building one should finish and fly it.

Hi

I;m in the process of building the DC version myself. I have followed your thread since the beginning. Very interesting. I am building mine relatively stock but modifying it to my liking. I am shoe-horning an OS 91 df with a prop. Having fun so far. An excellent builders kit.

Hi Jet!

Nice of you to join in on the thread .....can you post some pic's of your build and maybe a hint of your mods? I am like you ... some of the mods I have made are obvious and others are small and to my liking as well.

Cheers
