Default RE: ultra stick as a second plane


ORIGINAL: PipeMajor

I too, chose the US40 as my 2nd plane. My trainer was the LT-40 powered by a TT Pro 46. Great trainer! My son and I used it for our primary training. It took 6 flights each before we soloed. It now has almost 200 flights. I can spot land it with ease and can do inverted laps around the field.

Now on to the US40. I powered it with a Saito .62 and opted for the 4 servo wing setup. Guidance is via Futaba 9C on PCM. I couldn't figure out all the programming until others on this site "showed me the light". Setting up the Saito has proven a bit more of a challenge. I put nearly a gallon of fuel through it on the bench then decided to fly it. First half of the first flight was pretty uneventful. I took off (first tail dragger) and did two laps around the field then did a touch 'n go. When climbing back out I flamed out and turned back to land deadstick. Not a bad landing and no damage.

Next time out to the field we play around with the engine and it seems to be running well at full throttle, mid throttle and idle (still a little new so it doesn't have a super slow idle). Point the nose up and everything still fine. I set it on the runway and open her up. It climbs out and I turn onto base leg then it flames out again. I turned downwind but it didn't have very much authority so I sort of crash landed at the edge of the cornfield surrounding our field. Tore the LG block off. That was repaired but I've since decided to move up to 2.4GHz. I'm now waiting on the converter connectors to arrive since I'm going to use the previous Futaba S3004 servos. The new radio is the JR X9303.

I also ordered a new UltraSwitch with the JR leads. All of that should be here by mid-week.

Additionally, I acquired a used Sig 4*60. Won a new Saito 100 on eBay and as soon as my servo converter leads get here I'll guide that with the X9303 as well. I bought an extra Spektrum AR9000 and AR 6200 recievers. I suspect it will be 4-5 weeks before the additional receivers get here via the JR/Spektrum Giveaway promotion.
Saitos come from the factory with SUPER rich setting on the idle adjust screw. Follow the instructions to adjust it. You will find it takes quite a bit of turning-in before it settles in all of mine took about 2i/2 full turns. You don't want to do this until you have about 32ozs of fuel through it, which you say you have. It is not like a typical 2-stroke glow than needs little to no adjustment. Start with 1/8th turn lean and check transition. Keep doing this until the transition is bad and then richen it a little until the transition is good that is your setting.
