Hi Ralle, I sent you a Tutor decal enquiry, can you let me know if you received it or not? If not can you pm your email address?

Hi All,

After a 5 month delay (medical Problems)I finally maidened my C/A Tutor today.

The good news is it took off and flew beautiful. It required no trim adjustments. After about 4 minutes I decided to land to check things out.

I have a lot of flap dialed in but it still would not come down. it kept going and going and going. it finally settled on the nose wheel and bent the strut back and bounced back in the air. I did a go around, forgot to put the flaps up so that became interesting. It all worked out okay. My second approach was on the money and much slower. I still hit the nose wheel first again.

I have to say I can't remember hitting the nose wheel on any of my jets in the past.

I am sure I am doing something wrong, I know I need to get the nose up on landing. Maybe I am coming in way to fast.

I am open for any suggestions from any of you who have and are flying the Tutor. What is the secret?

Are any of you using Crow?

Thanks for any suggestions and information you can give me.

Hmm
Dean and I don't use crow they slow up really well I'm thinking you are carrying to much speed on final these are easy to land slow maybe try flying it around fully dirty up high and see how slow you can get it you might be surprised they do need to flare on landing
Good luck

thanks Kev-o

The more I think about it the more I realize I was to fast on the landing.

I need another nose gear strut assembly which Comp-Arf is out of. I ordered one but it is probably going to be awhile unless someone out there has an extra one or parts for one.


I hope I learn from this one.

If it settles on the nose strut, it means you are flying to fast and not flaring. Don't worry about making a slower approach. The Tutor will handle it.
I started out with close to 50 deg flap, but that proved too much and gave a strange elev. feel and flaring. Now I am at 40 deg, and it handles much better

The CG is important too. Too nose heavy does not help on the landings. My CG is at the centre of the wing tube now with some fuel in the tanks


Take a look at the pic. If balanced and flared properly, it will be able to land quite nose high.
The ammount of flap have been reduced after the pic was taken.

Trying going through Peter at Altecare RC he should be able to fix you up for gear. He may not have it in stock, but he will get it faster for you from the suppplier, as Comp ARF may wait until they have a boatload of product before they have it shipped.

Good luck

Sounds nose heavy to me combined with too much speed on landing?

Peter at Altecare stocks Behotec gear parts.

Ralle - in your picture the turbine looks low rather than high ? Its hard to get a dead centre picture of that sort of thing but, thats the way it looks. Also with the offset JetCat mounts you normally have to raise the turbine if anything to centre it so it would seem strange to need to lower it.

Regards

Colin

Stan,

Personally I prefer the recommended flap setting as it makes the Tutor super draggy and needing a healthy bit of power on the approach so you can control the speed easily. It does land very slowly but you do have to keep the nose down on approach until about the last 3 or 4 feet where just a gentle round out to a very slightly nose high but almost flat flare. The elevator is very powerful on the Tutor so I find tiny movements for the flare do the trick. I suppose everyone has their own style but that is mine.


Regards

Colin

Hi Colin,

"...get it down..." I meant the jet pipe...

yes, I can raise the turbine. but dont know if the trust axis will be right then?

What dia is the Grumania gold inlet? I'm guessing its different to the CARF carbon one and the pipe sits at a different height on the carbon heat sheild scoop? The complete carbon duct should be circular and the turbine sit pretty central in that. You are sure the tail pipe sits square to the carbon scoop/duct??

Regards

Dave

Ahhh I see! If there is no way at all to move the inlet to fit, I would imagine it would be ok to raise the turbine 3 to 5mm. As it is such a long pipe I don't think it would make much difference to the thrust axis ?

Hmmmmm.....

Kev-o and I had that problem with the stock pipe. Turns out the rails have offset for Jet cat type mount and we were using Booster/Hammer engines. We solved it by using a Jetcat mount but I see you already have a Jetcat. Maybe this pipe is designed for a non- Jetcat mount?

Alan thanks for the website. I will check it out.

Sap_2000 I will try a little less flap as I do have quite a bit in here now.

From what information I have gathered on this thread it sounds like the Tutor will fly a lot slower on landing then I was comfortable with.

In the meantime I have a machine shop making me a new oleo strut. I hope to be back in the air in a few weeks.

Thanks to everyone,
Stan

One thing I did not like about the Tutor was the rock hard stock Intairco wheels and the horrible sound they make when landing/ taxiing.

Changed the wheels today to SM F-16 ball raced rims with 105 mm airfilled tires and SM's very nice disc brakes.
Looking forward to test it soon. Should be a more quiet ride now

Has anyone had any ground handling issues on the take off roll on pavement. On two occassions now I have had serious problems where the jet wants to veer off the runway on the take off roll. I am just finishing up the fixing up of the second occassion's damage and don't want to have another. I do believe all the stock settings were installed. Maybe I should have more expo or less throw in the nosewheel. The last time I also had a gyro installed on the nosewheel,but I don't know if I had enough sensitivity dialed in. I think with the big tail and broad fuselage it could be easily turned by a crosswind. I have had no problems taking it off of grass. Any ideas or settings you would suggest.

Thanks Alan

Alan,

Have you checked your brakes? Sometimes the large o-ring on the intairco units can split and although it still works ok, it sometimes catches on that wheel causing the problem you describe on takeoff. As the plane slows down again it stops catching so its not immediately obvious that that is the problem.

I have seen this on both the Flash and the Tutor as there braking systems are the same - normally only after a lot of flights though.

regards

Colin

I have been flying in quite heavy crosswinds and never experienced this my self.
Could be several things. How is your toe-in? about 1-1,5 deg is fine.
At what part in the take off roll does this happen? High or low speeds?
I have heared of simillar behaviour with too high ground speeds and no back pressure on the elev stick so it kind of lifts of the mains. I hold about 40% up elev. during the T/O roll and it takes off when ready.
