I've had an Ultra Sport that similar issues with nosing over. The solution was exactly what you mentioned, simply bend you main landing gear so that they are a bent a little bit more forward. But don't do it with them in the plane as it's possible to tear out our landing gear blocks. Take the gear out of the plane and clamp them in a vice and then bend them forward a bit. I'm willing to bet that this will solve your problems.

OK, now that I have actually flown my UltraSport I feel qualified to display my brotherhood number.

Something showed up in the mail today. I have been trying to get my hands on one of these for a while.

That something is quite SOMETHING.

Enjoy and best whishes.

Intending a 'build thread' ?

Can do, not sure if it will happen this coming winter or not. I have a lot on my plate already.

Now I need to decide between my 120AX or 160FX.

DLE 30cc gasser. Cheaper to run, easier on fuel, and more reliable.

I want to stay old school with this one and install a glow engine. (slime and all)

My Feedback: (4)

I have one airplane left with a glow engine and I'm tempted to convert it to gas or electric (Big Stik .60 size). So I lug glow fuel to the field for that one plane. I have several other projects that I need to wrap up that were going to take glow engines but have decided to go electric since it's come a long way since I started those projects. The US1000 that RCKen is building for me is going to have a DLE30 with smoke and tricycle retracts. I'm excited to fly that airplane.

RCKen

My Feedback: (9)

I'm building the the US 1000 for sdcrandford and the one thing I'm looking forward to is being about to do a tricycle landing gear with retracts. Since we are going with a gas engine I can move the fuel tank back in the fuselage over the CG and that leaves me the area directly behind the firewall for the retrace mechanism to mount in.

This is a question for RCKen, forum Manager:

Hobby People has just come out with a sport pattern ARF that is clearly a copy of the Ultra Sport 60. I would like to do a build and fly series to see if it really is an Ultra Sport in disguise. But this is a Kit Building thread. Can I discuss an ARF here? Would the Brotherhood allow it?

I saw that plane at the Hobby People booth when I was covering the Toledo show this year. I think that we would be interested in seeing a plane that was based off of the Ultra Sport and see how successful they were in copying it. I looked at in when I was at the booth and it was close, but not an exact copy of an US so I would be interested in seeing how it flies compared to an Ultra Sport.

Wow, I would sure be interested in seeing that come together. Please post some pics if you get a chance.

With myself I have been glow engine free for about 5 years. I got back into some of them this year and I am having a blast with them. To me they will always have a place in the hobby especially with the .91/1.20 and smaller sizes. Once you go beyond that they just eat too much fuel and start to weigh as much as a gas engine anyways. I know when I used to fly my 1.60FX a lot it was nothing to burn over a gallon of glow fuel in a morning of flying.

Hi all:

I have been scratch building and kit building for 35 years. I have built Ultra Sports in all of the available sizes, both scratch and from kits. You might say I know the airplane well.

Although I still build, I also assemble and fly ARFs (so that I have something to fly while I build ) and I just bought the new Taipan ARF from Hobby People. The Taipan looks like a direct copy of an Ultra Sport 60, but is it really?

First of all let me assure you that I have no connection with Hobby People, I am not trying to sell anything and they did not give me the ARF. I paid full price for it.

And finally, I hope no one objects to my discussing an ARF on the Kit Building forum. I checked with RCKen and he thought it would be OK.

OPENING THE BOX: (I did not take photos of the individual parts as they come out of the box, but you can see them on the lower left corner of the box top.)

• There have been changes to accommodate electric power as an option. The second photo shows the battery hatch. An electric motor mount is included in addition to the glow engine mount.
• It uses one aileron servo in each wing, the rudder uses pull-pull cables and the elevator servos are mounted near the tail.
• The box top says it uses 6 full size servos, but the servo mounts for the ailerons and elevator are for mini servos.
• The cowl is fiberglass, but the belly pan and wheel well inserts are painted plastic. See third photo.
• Fixed gear is included, and the wheel wells, gear mounts and servo mounts are included for optional mechanical (or electric) retracts.
• The covering is sticky-back, heat shrink, shelf paper. Both the paint and the covering will be ruined by any solvent other than alcohol or mineral spirits (paint thinner). Even my CA accelerator melts the paint.

In short, this airplane is updated to handle todays power systems and radio technologies, but it can still handle traditional glow power and mechanical retracts. (GOOD) The materials and build quality are typical of low priced ARFs. (OK, for the price.)

I will update this thread as I assemble the Taipan and then fly it to see if I can tell the difference in the air.

jrf,
Keep the info coming! i ordered the Taipan earlier this week myself and it should be delivered today actually so i am real interested in your thoughts!

Was considering retracts but didn't want to spend the $180 (I think) Hobby People wanted for the recommended set so I may just go with fixed gear. Not sure if a mechanical set will fit...

Plan is a K&B .61 glow for power.

Thanks,
Bill S.

Twin flyer:

I checked around for retracts. If you have an old set of mechanicals, they will probably fit perfectly. (I used a set of old Hanno Pretner gear.) Tower has a set ( LXL407 $19.95 ) that will fit. I found that the standard 40-60 size electric retracts from Hobby King will fit also.

Wait till my next installment before you join the wings together.

After watching a guy in my club sweat electric retracts were awesome and started using them in everything (HK brand or the like, not Robart) and then have nothing but problems with them, i will happily stay will air or mechanical. They may be a pain to set up but once thats done, its done!

Kit was waiting for me when I got home, so i will wait... but not for long!

I will try to do an update everyday. Tomorrow will be the wing, with servos and retracts. Here's a teaser; they eliminated the dihedral. Bad idea.

My Ultra Sport wing when laid upside down on a table is flat.

If Hobby People tried to copy the ultra sport they did a bad job of it, the nose on their plane is to fat

jrf

My Feedback: (551)

KaP2011:

Yes, that is the way it should be. Because of the taper in the wing, when the top is flat, the bottom has 4 degrees of dihedral in it. The average of the top and bottom is 2 degrees, so technically the Ultra Sport has 2 degrees of dihedral.

The Taipan wing has 2 degrees of anhedral (negative dihedral) in the top and 2 degrees of positive dihedral in the bottom. The average of top and bottom is zero. No dihedral. That is not a positive change. I will explain tomorrow. (It looks droopy too.)
