RE: need roll pin for K&B
[quote]ORIGINAL: earlwb When I first saw the thread I was thinking about this engine here that I have. It uses a small roll pin and a set screw on the drive washer. I had forgotten about the rear intake engines you depicted.

RE: need roll pin for K&B
a couple internal differences as well..........rotor is supported by a bearing, rod is machined instead of the cast that were used in the production series.

RE: need roll pin for K&B
the 3/32" roll pin as used on the K&B 40-S is/was easy to find. the trick is to drill thru the driveplate/crankshaft......... i'll upload a pic later tonight. this one is of but a very few that John Brodbeck did up for a select few...the one i have is from Joe Bridi's collection that John gave him. i really appreciate all the input from you guys. nothing more fun than to BS about engines.

RE: OK fuel guru's....here is a tuff one
[quote]ORIGINAL: hauckf [quote]ORIGINAL: JCINTEXAS Pour 12 ounces of nitro into 88 ounces of your original fuel = 100 ounces of new mix at 25% nitro and 22% oil [/quote] I think that will only get the nitro to about 21%, not 25%. To get to 25% nitro, pour 16.7 oz nitro into 83.3 oz of the original fuel. The resulting 100 oz of fuel will have 25% nitro and about 21% oil. Or, just pour 25.6 oz of nitro into a gallon of the original fuel to get the same result. (I think JC used 15% nitro in the original fuel in his calculation, not 10%) [/quote] hauckf, thx for the formula. appreciate that you understand what i am using and trying to modify.............i'll juice up a quart first and if that works then i'm set. worst case scenario- BUY NEW FUEL[:D] and give the 10% stuff away...... thx -mike

RE: OK fuel guru's....here is a tuff one
i would like to keep the oil percentage at no less than 20%. the fuel was originally bought for use in a couple older RC engines that were designed to be run on castor oil fuels with minimum 25% oil. the conrods are non bushed and would die with synthetic oiled fuels. the engine i want to run this fuel in now is the K&B 40RR from the late 60's which also have non bushed conrods.

then again maybe not........... fuel in my stock is Sig all castor fuel. 25% oil, and 10% nitro content. need to bring it up to 25% by aqdding Nitro, but i'm not sure what the amount to add would be? why fool with it and not simply buy more you might say.........i have 4 gallons of this and don't want to toss it if i can make it work.

RE: RC Plane Guys Are Cheap!

Sit back, take a breath, and relax. Don't let something as trivial as this ruin your day.

[/quote] talk about "not getting it".............you missed the whole point. i could careless how long either vendor takes to "pick and pack".........................i said (and let me be very clear) that Horizon is top notch in getting an order processed and out the door. i did NOT SAY that i was upset or in a hurry.................i DID SAY that Tower on the other hand takes a lot longer to process ones order when it is being handled under their "FREE SHIPPING" per 100 bucks spent, but will ship immediately if one pays for the upgraded shipping.....how can they do it faster, becuase now you are paying for the shipping probably........... i never go online and pay more for shipping than necessary, and i never give much thought to the order once placed, only to check what i receive when i do receive. i merely posted a KUDOS to Horizon as they seem to think shipping an order immediatley is important to their customers who have just spent money with them..................did i miss anything here?...................or do you still not get it? this is what i mean as well as people who posted other than what is concerned here in an attempt to point out that I am impatient. god, why did i even bother logging in here................

i have placed 3 different orders with Horizon in the past 2 weeks.......i just had to say Kudos to them as each one was processed and shipped within 4 hours of placing........this is how things should be done for us modelers who support them by buying from them. i wish i could say the same for the once powerful and mighty Tower, but the last 2 orders i placed with them has been the slowest service i have ever seen ....72 hours to process and ship?........c'mon Tower, you can do better[;)]

RE: Need help with prop tracking...
[quote]ORIGINAL: tacx Summerwind... All good info, but you are referring to checking the engine drive washer and shaft. I think we are mostly discussing the prop. If you have a prop that has a rear hub surface that is not perfectly parallel to the prop blades then that prop is not going to track correctly. The only way one can check a prop for tracking is to use a prop. I understand the fact

[quote]ORIGINAL: jetblast96 [quote]ORIGINAL: Hobbsy ...notorious for having the hole drilled crooked through them. [/quote] Should I not use APC on my airplanes then? The only reason I'm checking prop tracking is to get a smoother running plane without all the massive vibrations that I've been experiencing. I have no doubt that my drive washers and crankshafts are straight; these engines have not been crashed and the Saito has only been run twice on the bench; otherwise factory new. Should I switch to a different propeller and try again? Thanks for the replies Mike [/quote] are you serious?..................it's not the hole even though that is the obvious suspect. you need to make sure the back of the prop hub is true first. any prop can be off, and you need to learn how to check that first........but still, using a prop to check for tracking is pointless whether it's reamed out correctly or not.............when you tighten a prop down it has no choice but to sit flat on the drive washer does it not?...........
