Thanks alot. Don't you just love the sound of those gassers when they throttle back in the air.

I tried www.parcsrcmodel.n and could not find the link. Is it spelled right.?

Sal 98 glad you enjoyed the video.

I found that I had to lean the high end on the BME 50 after about 3 gallons of fuel. Maybe 1/16th turn and remember to go to high idle when taking off. No more dead-sticks.

Engine broken-in "flying" from the start as per BME manual. There may be a better way but decided to follow Keith's instructions.

ive got over 40 flights on my BME...and so far - all ive done is lean out the low end about 1/8 of a turn...although - i think its about time to adjust the high end too - she maxes out on rpms somewhere about 2/3 full throttle...and the last 1/3 there is no change...

BUT - ive only had ONE deadstick - and that was because my cowl severed the ground lead to the ignition...

next time out - ill tach it and report back...

drj, have same situation. Full power at about 2/3 power on transmitter. No increase of rpm's. Any help???

I have a buddy that is having the same problem on a 3W70. We think it might be a torn or punctured diaphram which doesn't allow the motor to come up to speed. (Not sure yet, but this is what we are checking into.

RCguy and Jan,
Try programing in Expo on the throttle to have more throw on the stick through the low end.

Did the maiden on on my Patty today! CG 6-3/8" at the root, don't know the weight yet. Jumped off the ground with the Brison 3.2 but needed some down trim.

Inverted I only needed to think about adding down eleveator to stay level, really I just touched the stick twice as lightly as I could for half a second to stay level during about a ten second inverted run. I think the CG is perfect for 3D at that point.

Low rates (9/16") elevator looped fairly tight at 1/4 of the stick and ailerons were very responsive. I'll program in expo on everything for next time.

She slowed to a crawl with no hint of tipping.

After only one flight I was very happy I got rid of the Lanier Cap to get Patty. Had engine trouble that turned out to be a clogged carburator filter so didn't get anymore flights in today.

I havn't even sealed the control surfaces yet so it should only get better.

Your right on the money BasinBum, You have to add expo on the throttle of these pumped carbs to get a linear throttle response. the walbro carbs are generic and really not made for our planes. With weedwackers, trimmers and chainsaw your not really concerned with a linear throttle response.

Hey Guys,
What radio are you guys using? I know on the JR 8103, there's a way to program a mixer that gives you a 5 point curve. So you want to start with idle rpm, and that's your low point on the curve. Then get the highest rpm and that will be your 5 point. Divide the difference of rpm by 2 then add your idle rpm and that will be the center or mid throttle point 3. Now program points 2 and 4 for the feel you like and you have got a full, even throttle curve throughout the range of the stick. Does anyone have an easier way for the JR radio?

What about a Zenoah 62 on the Wagstaff?

Golfweapons,


It would work, but WAY too heavy. Read earlier discussions about which engine. BME, DA, ZDZ, Brison are the most popular.

John

That's the right way to do it.

My radio only has 2 five point mixes which I use for rudder coupling on elev and ailerons.

I have a 9C, and I have found that some guys know how to do it with a single point mix, but for me using expo works just as good and I don't use up any of my mixes.

Expo works for me too. It's simpler that way too.

If I only had a radio with expo on the throttle, that would be great.. Live and learn huh?

Another excuse to buy something for your hobby.

The 9c was my 2nd radio from a 4 channel wich comes with an avistar.

I think this is the single most important investment in RC.

I've got a whole garage full of stuff that I tried to get by with for the least amount of money. Boy, if I had known then what I know now, I'd either have a lot more money in my bank account or all my planes would be gold plated -- well, maybe gold leafed.

how much expo did you end up with? +or-

Futaba radios use negative numbers to soften the sticks.

I wound up with -40% for my ZDZ 40rvl.

Using Futaba 9C. Expo is the way to go. Fixed problem. Thanks.

thanks , sal98. ill try it , i have a fuji50sb on my patty an have the same problem with throttle.

hey guys i stopped getting any email on this thread and now every time i come to this web site i get a serious LAG time it takes anywhere up to fifteen seconds for the screen to catch up to what i,m doing HELP, Is anyone else having this prob???

I stopped getting emails as well. I'm hoping that this reply will reset the email notification.

300sjack,
try cleaning out your temp folder under control panel,internet options.

Andy

When I don't check my email for a few days I usually have several notices waitng for me. To day I had 3 notices.
Then there are other times I don't get anything until 5 or 6 posts latter. Go figure.........
