Noobie needs a little engine advise
I have a HobbiStar 60 with a OS 65 LA. I stumbled acoss a new TT .91 4-Stroke, and was wondering if it would be worth throwing in the HobbiStar 60. Ive never flown a 4 before, and not know what to expect if I put it in the 60. Im waiting for my 4-Star 60 to get here next week, should I just wait to use the TT .91-4 in that?? The .65 LA runs great, but Im the type that likes to be different..
Thanks for any and all input you guys can give me... Scoot

RE: Noobie needs a little engine advise
I think the 91 would be enough in the hobby star, a 91 is about the same power as a 60 2 stroke. I would want more in the 4 star, a 150 saito would do the trick. I say it better to have too much power than not enough. If your new to 4 strokes, you need to follow the manual for the break in and remember that running max rpm after the break in is not important, I usually go about a 1000 rpm under the factory max.

If thats a metal motor mount, I would change it to a fiber-reinforced nylon mount. If you crash it you will break the mount instead of the crankcase

RE: Noobie needs a little engine advise
It's not a bad idea to use the trainer as a break in tune up plane for the four stroke, the four stroke is quite a bit more engine then the LA. The metal mount is something that is recommended for four strokes so they don't flex the mount. If you buy a new four stroke mount from any of the manufactures it will be metal. I have used the Saito 100 in the 4* 60 and it's about the perfect combo, the .91 should be just fine.

Scooter, pick up a Dubro flex-cable .if your going to install the.91 in your 4 Star, it might come with one, I can not remember for sure. But a flex cable really helpswhen installing the 4 stroke linkages.

Well that will work fine in that airplane also. Sometime using and old beater for an engine hack to familiarize yourself with new types of engines does have some merit. Have great maiden this morning.
Are you flying at Eldorado lake?

RE: Noobie needs a little engine advise
Yes the whole region is having only a very short morning window with exceptionaly high noon winds. I have a Stinson Tri Motor down here waiting for a maiden now also.
It looks like the region may get back to normal patterns by the middle of next week, I hope.
So Apex is the name, thats what I was looking for and never know the name. Thats the one northeast of town close to the interstate and just the other side of the AF base. I,ve flown at Eldorado, Jean and flown some cross country that terminated at Apex and there seems to be a large more or less permanent line of motorhomes always there on the weekends, even a portable frequency board. Has been a few years since I,ve been there though.

Friday was a perfect day at Eldorado!! no wind to speak of and it was 84 in the late afternoon when we left. Could have been out there until dark it was so perfect!! NOw we are back to our normal spring winds. Good time to be working on planes. I needed to run up a couple of planes to do an RF and engine test but it was too windy to be out there in the street fooling around. Went shopping yesterday and it was hard to walk cross wind!!!

Thanks OKA
GB we tend to be morning people down here and can usually count on good flying wx most days every spring early in the morning. We start trickleing in about sunup and most are gone by 10:00 AM.
Got good news today, Red Lake which is about half way between Las Vegas and Kingman just south of meadview is dry now and flyable. Been waiting to make some flights there from Kingman.

I would want more in the 4 star, a 150 saito would do the trick.

The 11x10 may not be enough prop load for the .91 four stroke.
My favorite .91 prop is a 14x6.
You want to keep the rpms around 9,500 to 10,000 (on the ground) at wide open throttle.
