Well that was another option I was thinking of..
Looks like I have a lot of reading/researching to do.
In the meantime, I think I'm going to get me a Saito .91 and throw it in my UCD, I havent touched a set of sticks for almost 2 years now. I'm sure I'm very, very rusty and need to get some practice...

Ummmmm......are you talking the .46 sized UCD or the .60 size UCD?? because i just jumped onto this post , and i'll tell ya , i'm a friggin master UCD flyer and builder ( well...maybe not flyer) I personally had the UCD 60 and i put a saito 125 on the front of it. It balanced fine and power to weight was just perfect. You have to remeber the 125 is just a hair heavier than the 100 , and has quite a bit more power. I think as far as 3D flight goes......that .91 isn't going to cut it. I wrecked my last UCD from a stupid dumb thumb , but that was one fun flying little plane. BTW....another due at our feild had one with a YS 110FZ on the front.........it flew exactly like mine did too.......friggin awesome little $179.00 airplane.

You and Gary didn't do all that bad with the Funtana's either
I'll never let Gary fly one of mine again unless he first promised not to do his low level reversal without warning me first... Near had a heart attack[X(]

I cant tell the difference between the saito 100 and .91 except 300 rpm for 30 bucks. I went with that. Welcom back to the sport!

RE: 50cc Sukhette Build Thread, now in progress!!
So anyone else with any big differences in the weight of their wings? I have most everythin spaced equally throught the airframe and it still drops a left wing in almost all attitudes. I weighed them and they came out 2+ ounces different. I am going to try to balance the right wing with lead tape to see how much it needs before peeling the covering, drilling a hole and adding lead shot. Sorry for hijacking the UCD Thread...

2 ounces is not really much for wings this size. I wouldn't think that any of the manufacturers are weighing wood and checking densities before the stuff hits the cutter. The extra charge would be astronomical. Rather than peel covering, might it be easier to insert weight in holes drilled in the wing tip and just put a small patch over the holes?

RE: 50cc Sukhette Build Thread, now in progress!!
I had to add 1 oz. to my right wingtip and have everything else balanced laterally. Figured 1oz wasn't too bad based on wood densities and the amount of glue used on each side...
Maiden for mine is next weekend. Fired up the DA and set high/low idle and checked for linear throttle response. All ready to go so getting ancy. Haven't added graphics yet and will this week.
Here's a couple snapshots of the interior setup... I used the snap linkage on the throttle for length and have replaced it with ball-joints so no worries there

Nice neat build Henna. I like the black paint in the engine area....assume you'll paint the inside of the cowl black as well? That always makes for a nice look and sets off the engine.
I've yet to jump onto the giant scale wagon, but really like what I've seen here from Wildhare.

Thanks - I did paint the inside of the cowl black as well. I debated red, but the black looked much better.
This is my first large gasser (even though years of Nitro and Electrics) so new to the experience as well... Very happy with the WH plane so far and can tell that I'll own a few more WH planes before all is done...

RE: 50cc Sukhette Build Thread, now in progress!!
Just watch the engine temps...mine was overheating and despite what Tom says i dont think theres enough cooling at 100f outside temps.
Same setup as yours.
Would sag after a few minutes in the air despite needle settings.
Added a baffle and will try it once my wing tube gets here as I bent the original.

You might think about "cheating" a little bit. The bottom lip of the cowl is dead in line with the top of the head. Cutting an oval air entry in that lip helps with cooling more than you might think.

RE: 50cc Sukhette Build Thread, now in progress!!
Put a few flights on mine. Harriers and elevators had very little wing rock. Knife edge spins and knife edge elevators no problem. Very tight inverted flat spins. Rolling harriers super easy. Quite a bit of pull to belly on knife edge as well as a lot of down(UP) for level invert flight....which leads to this question. Am I nose heavy b/c of so much down(UP) needed for inverted flight??? or tail heavy b/c of the large amount of pull to belly in knife edge???? or something else.. FYI: No elevator trim was needed for level flight and when throttle chopped from full plane flies straight and level forever! Thanks

RE: 50cc Sukhette Build Thread, now in progress!!
If it takes a great deal of down to keep it level inverted you're nose heavy. Coupling towards the wheels is normal in knife edge on many, many planes. You can mix that out. If you pull a 45 degree up line inverted the plane should hold it if it's balanced properly.

RE: 50cc Sukhette Build Thread, now in progress!!
Thanks Lou55. I will remove the 4 ounce spinner and try a few more flights. I'm using the forward position on the horizontal stabilizers and the plane is very pitch sensitive. I like the way the plane flies a lot as is, but wanted to be careful decreasing nose weight b/c the plane likes to balloon with up elevator upon landing.....not that big of an issue but the field is very short in between two rows of trees, so not a long distance to bleed off speed! This plane is so much fun! And the canister is so quiet[8D].

RE: 50cc Sukhette Build Thread, now in progress!!
The plane will be much, much more sensitive to pitch inputs with the forward stab position. I agree with Lou on the c/g condition. It's quite possible that your stab position is contributing a lot of the pitch to the gear. With a fairly neutral CG and aft stabs there is very little pitch to the gear in normal KE. High alpha KE for straight flight has a bit more pitch, and a KE loop encounters some roll coupling along with the elevator.
I don't know if you tried any fast KE spins but she goes around almost too fast to count when you toss power at it in the spin. It's pretty easy to start a slow KE spin then increase the spin rate as desired using throttle. She gets real fast! Funny that the descent rate does not increase with the spin rate. Remains the same fast or slow as it comes down.

RE: 50cc Sukhette Build Thread, now in progress!!
I had installed my stab in the forward location as well (holes were there already). Will fly it this weekend and see how pitch sensitive it is - looks like the general consensus is to go with the aft stab position. I enjoy 3D a bit more, so we'll see how this fits the bill...

RE: 50cc Sukhette Build Thread, now in progress!!
Henna, mine is in the forward position and it is as stable as anything. Other than needing to balance the plane laterally, its darn near perfect. Even with a heavy left wing, it seems to want to fight stalling. I gotta say this is the best airplane I have ever owned and flown. I too was worried about the forward position. Not any longer. If it is more stable in the back, it has to be a precision monster.

RE: 50cc Sukhette Build Thread, now in progress!!
Where's that damn UPS guy... Lucky for me I have the day off tomorrow and Thursday... I can sit and twiddle my thumbs while I wait for it to show up!!
I almost have my Eflite Cap 232BP finished so I can get my fingers warmed up.... I obviously need it since I crashed my brand-new, just purchased 2 hours ago, F-27C Stryker on its maiden into our town's water tower yesterday...
So what's the verdict on the engine? I'm leaning towards the TOC 53 unless someone can convince me the DL is a better choice. DA is out due to price...

Speak with Tom about both. You may have a surprise when you do. The 3MM is a fine engine. Strong and dependable. THe DL is a little short on track record but a higher revver and a little lighter. Either engine would be an excellent choice.

This sucks..
I'm stuck at work till midnight and my brother called me to ask what was in the huge box UPS delivered[:@]
I did specifically ask him if the box was beat up badly, and he said not at all.
I can't wait to get home to rip it open. I wish I could find an excuse to leave work early[>:]
