    Increasing Gross Weight

    The one light plane I've owned, had trim and used a lawnmower throttle to adjust it. I never used it. Good advice. I shall heed.

    Increasing Gross Weight

    I have no concerns with the weight. I will happily do the whole HBA documentation/certification/registration thing. I just want build on something akin to a part 103 budget. Since the threat is about increasing gross weight, I have little hope of it being super light.

    Yamaha 701 PWC engines -- why not?

    I appreciate the input regarding the YG engines and the color commentary about Steve's most recent engine choice. I'm actually a fan of the tech you seem to be promoting, but after several searches and identifying your business as Mohawk Aero (I think), I finally got to your website...

    Increasing Gross Weight

    Ir27, As I opened that Ben Syson article, I realized that I'd read it before--not long ago. It's great engineering data. While it doesn't address square tubing, the info will be useful as I address stronger wings spars and struts. As for covering a LE..., I hear great things about how she...

    Increasing Gross Weight

    Charlie, Paul just crossed 1100 hours on his Airbike! Ours never climbed that good for me (265 lbs at that time). On a hot day, forget it. I was never a fan of having my knees in the wind either. Looks awesome on the ground, but acted like a drogue chute prying my legs open. Enclosing the front...

    Increasing Gross Weight

    Great comments guys! This is really helping my thought process. Ir27, I considered higher wing loads and faster approaches, but this seems like trouble squared to me. If I keep the wing load consistent with the original design, logic suggests a far better chance of success since such loading is...

    Yamaha 701 PWC engines -- why not?

    That's a nice pile of engines there. Too bad they all seem air-cooled and of course, the certain damage of the elements. Air-cooled engines (including my 447) always seem to run hot on the back jug. The heating problems give some Rotax's such a narrow band of 'good' performance that it's too...

    Yamaha 701 PWC engines -- why not?

    I appreciate your thoughtful response Armilite. It's true that many good engines exist already set-up for aircraft with Rotax leading the pack. Affordable, however is a matter of perspective. The reason for looking for alternatives in PWC and sled motors, is the difference between thousands and...

    Thank you. I will add this to the many things I plan to study.

    Yamaha 701 PWC engines -- why not?

    Forgive my ignorance... 'TV'? My main concern with the idea of these two particular motorcycle engines is, as you indicate, the vibration associated with a single jug. Though more modern engines seem to go a long way to address this. It's hard to anticipate. Probably best to talk to someone who...

    Yamaha 701 PWC engines -- why not?

    Rik-, I am familiar with Steve Henry. He hangars his planes at KMAN where I work part time. Fantastic engines! But I'm looking for Affordaplane power, where 75hp is MASSIVE. The big R1s are an order of magnitude or three beyond where I need to be in power and price. During my day of learning...

    Increasing Gross Weight

    Thanks gents. I have read a great deal herein about the AP in various threads. I am aware of its detractors and the reasons they state for their position(s). These are areas I wish to address. I do own the plans and study them regularly and I've already learned a great deal in response to...

    Yamaha 701 PWC engines -- why not?

    At Turd's suggestion, I am looking at liquid cooled snowmobile engines. They tend to be very high horse-power and finding listed weights has so far, been unsuccessful. The Yamaha VMax 600 engine is intriguing, but at 92hp would have to be de-rated. Perhaps this would increase reliability--don't...

    Yamaha 701 PWC engines -- why not?

    Turd, My knowledge of snowmobiles is limited. Are there closed-looped cooled engines with the kind of power and weight as the Gen II Yamaha 701 that I should be considering?

    Increasing Gross Weight

    I've studied the pros and cons of many designs and measured them against my needs and desires. For a variety of reasons, I have chosen the AP, not for its designed performance, but for its construction methodology. Like countless builders before me, I hope to add a degree of individualism to my...

    Increasing Gross Weight

    There has been plenty written herein about the Affordaplane and the engineering of the design. I am currently sourcing some engineering texts related to aeronautics, but perhaps someone here can offer a quick, yet academic answer. I want to make whatever changes are required to increase the...

    Yamaha 701 PWC engines -- why not?

    Lively conversation. Engine options at realistic prices have always been a challenge in HBA. I agree that a PRSU shouldn't be too much of a challenge even if it must be fabricated. As much as anything, I just want to add something meaningful to the world of completed homebuilt aircraft once I...

    Yamaha 701 PWC engines -- why not?

    Good advice. I have no need for mods or extra power. 73hp or even the 63hp older version is tons of power for something like an Affordaplane. The Yamaha 650 (older still) would even be fine at 50hp. Maybe limiting the 63hp to 6000rpm putting it in the mid 50s is worth a look. I know that you can...
