**"Oshkosh Special" with video and plans + Kfm3**

Okay,

Time to start a thread on this. I as some of my FB's know am in charge of an RC Flight Experience event in Oshkosh, WI this year. It is part of a larger event that happens every five years, the International Pathfinder Camporee. This will be the third year it has been held at the campgrounds of the EAA (Experimental Aircraft Association) from August 11 -15, 2009. This is just a week after their annual Airventure gathering. Pathfinders and Staff from around the world will gather to the tune of 33,000 participants. Many different events will take place on and offsite. The RC Flight Experience is just one of many. We expect to service about 200 people a day for four days. www.camporee.org


Here is what I am doing and invite your input. The plan is to build a fleet of 8 aircraft. Foamies of course! My initial plan was for 33" UC Blue-Babies. Then I thought to create a modified version of the Blue-Baby named the Oshkosh Special. Inviting comments and design considerations. They must however utulize the above components.

Ken

Maybe figure out a way to do a shoulder wing open cockpit version? A lot of experimental planes are open cockpit, so it might work.

The unveiling

I suppose a Petienpol Camper would have been more in keeping with Oshkosh spirit, but I did mention a modified Blu Baby 33 UC. Ended up doing exactly that.

Here are the mods and specs;
  1. 33" wingspan stretched to 40"
  2. Fuselage stretched 1.5" behind the elevator
  3. Fully tab and slot construction
  4. Monoblock will be laminated from FFF PB3 (prototype is solid)
  5. AUW with 1000 Mah 2s battery is 10.2 oz
Plans will be forthcoming for those interested.

That is very pretty. I need to build another BB for a young man that is learning to fly. This looks like a nice variant and the specs for the electronics are nice and simple too. Hope you will be publishing plans for the Oshkosh Special BB.

Looks like a Texas 150. THose are the Cessna 150'S that people converted to a Taildragger. Nice planes!

I just looked at the motor combo. That may be a little lightweight for this size of plane. It is saying that it can only handle 12 amps. I had a motor that was like that before and found that it was very underpowered.

I use this combo all the time now and it is great!

Shipping is usually about a week so plenty of time to get them and put the planes together. These can do 22 oz of thrust!

My design

I am really enjoying this one. This is the second one I've designed. Cheap to build, fun to fly and durable.

Just to pull this back to the BB. I flew an entire pack this morning doing touch and goes with my landing gear and UC wing installed. I am amazed at how docile this plane is and how precisely one can land it. I used the same throttle and trim adjustments that I used when I used to fly Cessna 150s and 172s and it was a delight. I flew a tight pattern and when on final simply used throttle to control my rate of descent. Once a few inches above the ground ease the throttle and feed in some up elevator. Yes, this is the way it is supposed to be done but few RC planes I have flown have responded so precisely and nicely. I have become a BluBaby addict.
