Maudib; what you just posted about those Lipos is right on. I purchased four cells from BA and destroyed two of them attempting to solder them together. Those doggon tabs didn't break off the fell off[>:] I agree with you , the chemistry of Lipos is quite dangerous compared to Nicad or NMh. But these batteries have no competition when it comes to performance and weight. I pull them out of my planes at home for charging. I put them in a huge lobbster pod and don't worry about a fire hazzard. I charge them only when I am home. Here are a couple of pix for drumbum to show him my interior.

You bet... a full lb ighter than the lightest 50's out there...

They WILL BE shipping with Falkon Ignitions... I wonder how that will work out.

The interesting thing is that this becomes a DIRECT weight replacement for all the 2.4 ci engines not to mention direct drop in replacement on Saito 2.20 and O.S. 1.60FX aircraft...

It comes in both side mount and rear mount carbs so the airframe can dictate what's best.

I sure hope someone comes out with a muffler similar to DA's stock 50 muffer... It's a little over 4 oz when the sack is cutdown and is sufficiently quieting but allows good power.

If we could get something like that...

33.6 oz engine
4 oz for ignition (guesstimate)
4.2 oz muffler
2.3 oz for 730 mah AAA Nimh
.5 oz ignition switch

44.6 oz

2.79 lbs!

The Saito 2.20 weighs 42 oz not including the 7 oz or so for Rail mounts. Plus you'll want 24 oz of glow fuel instaead of 16 oz for gas...

The O.S. 1.60FX with muffler is 41.5 oz so about the same as the Saito...

The BME 55 will be LIGHTER and MORE powerful (and a WHOLE lot cheaper to run)

With a 55 in the Ultimate... You'd be looking at 13.5-13.75 lbs! Unbelievable...

Maudib do you think A ZDZ 40 would fly the ULTI well do you recall length from firewall to back of spinner.

Maudib 01-22-2006 09:45 PM

RE: Great planes ultimate 160
 
The ZDZ 40 is a powerful little 40 and would do pretty decently... it's a little lighter still yet than the Fuji if I recall. The suggested distance is 7.25".

Good news is that there is coming a NEW ZDZ 40RE (rear exhaust) that is only 2.4 lbs!!!! There is a nice inv. pitts available for the RE too...

I'm full of new surprises lately... :)

after thinking about it.. if BME can come up wit a 55 CC motor thats as light as that then they can come up with a motor as light and as powerfull as a YS-110 in the same class... IM sure they would be selling so many of those that they would be like YS.. by not being able to keep it in stock ,, I know i would be buying at least 4 of them on my first order;).. im calling BME and preordering the 55 for my YAK that i robbed the 50 for for my ultimate...

yea you can fly it Extra Addict:D I finally got a dialup account since waiting for my broadband has been a adventrous experience

RE: Great planes ultimate 160
 
Funny you should mention that as he released a SuperTIgre .90 converted to gas

http://www.bmeengine.com/html/point90.htm

He states that it is MORE powerful than the same engine on glow... hard to believe but that's the claim. ALso states that you need a LTO less fuel on takeoff so weight is about the same overall....

I rather imagine if this sells well we'll see other SuperTigre glow conversions... They have the G-2300 a 1.4+ci maybe that would prove as powerful too... :)

7.25 works out great forZDZ40 would not need to cut firewall the 40 flys my H9 xtra great hovers just under 1/2 throttle at 14 lbs should hover an Ulti at half I think I will get me one next week.

How well is the tailwheel working? Would it be feasible to use something like the graph tech?

thanks

Maudib 01-24-2006 06:43 PM

RE: Great planes ultimate 160
 
I really think it will be fine, but only time will tell overall. Mostly any of the popular tailwheels will work well, inclduing Chip Hyde's small tailwheel...

I used Ohio Superstar Products tailwheel. I had to build up the plate in the tail a little bit but it was easy.

you can find these at chiefaircraft.com

I used the stock tailwheel but shortened the length to the anchor point in the bottom of the rudder and it's worked great, positive steering in high grass.

Slyder 01-25-2006 06:45 PM

RE: Great planes ultimate 160
 
Did I read right that they fixed the weak gear? Also is there enough clearance for a 23" prop?

Thanks again.

iflywhenican 01-25-2006 06:54 PM

RE: Great planes ultimate 160
 
The "fixed" gear was a replacement of the exact same fiberglass gearset that was shipped in the kit. My definition of a fix would be a aluminum gear replacement. So far, other than a little chipping on the left gear leg, mine is holding up just fine though.

RE: Great planes ultimate 160
 
I've looked through this entire post and did not see too much mentioned about using a Moki 2.10 for the engine and what kind of performance the plane would have using it.

I am thinking about using a Moki 2.10

I personally think it would be a good engine choice, I was hoping for some other input on this question.

Thanks !

If glow is your goal, then the 2.1 would be the epitome I'd wager. I;m sure the 1.6 would fly it like the 43cc Fuji does... so I rather imagine the 2.1 would be much like having a 50cc on her... real nice... :)

Well glow is really not my goal, but I do have a Moki 2.10 laying around gathering dust.
I know the biggest drawback to glow would be fuel cost.

Sounds like the Moki 2.10 would have enough power though.

Thanks !

Yep, the set I got from Aerobob has lived through quite a few landings now, so it really does appear that I had a bad couple of sets. I did hear back from GP 2 days ago and they are not doing anything :eek:.

I also used the stock gear but added a little bigger/better wheel as the foam one final flatspotted after sitting on it for about 2 weeks and have had no problems at all on grass. This plane really is one of the few that does not need allot of changes. The stock stuff is nice and works well enough.
