    Briggs vanguard conversions

    Around 14 hours, starts instantly but had to upgrade the reduction to cope, plus the prop in the video is 60" and too small, had to add 10 degrees at tips to force revs inside limits. Getting 1100 feet per minute, trialling a 64" now as when fitted it ripped the drive belt to bits. Ordered new...

    Briggs vanguard conversions

    Briggs tuned is light enough at 40 kilos fan cooled and 35hp OK for a single seat delta trike, but wanted bigger climb. Bought an 800cc ATV motor and beefed up the redrive design to suit, got it made by Ace Aviation, total is around 60-65 kilos, YouTube channel for typical history here

    Ace Aviation Redrive: New model

    Hello John As you know I'm using one of these redrives to accept the output from a Gaokin liquid cooled EFI V Twin, it's the same engine fitted to the HiSun HS300 ATV, https://www.hisunmotors.com/ sold in the USA, so is in a gentler stage of tune than a motorcycle engine, and doesn't need a...

    Electric trim motor for adjustable tailplane

    Used a Hiwin linear motor to move a trike back and forth on a weight-shift, more than man enough, beautifully made and won a prize for the modification. LAS 50 and other stroke lengths, was my favourite, needs a multi pole rocker switch, spring return to mid position...

    belt redrive for rotax?

    Did a design around 5-6 years ago to install a 14 row multi V belt redrive on a Briggs, 1:1.8 ratio, but the people I got to make it will do others, currently got an upgraded version with 19 rows on a fuel inject 61 hp ATV motor with 2.2:1 ratio, giving a 6000rpm limit with three carbon prop at...

    ACE redrives for most commercial engines.

    Driven from this forum indeed...however now puzzled Wife is getting emails notifying posts on this forum, must be a glitch in our Outlook setup, so have had to add it to her spam filter as well as mine, as there's no means of unsubscribing. One contributor wrote of his 'successful career in...

    ACE redrives for most commercial engines.

    Thanks Ultimate test of the reduction drive was rather more than surviving a mere 'hard landing'; trike was rolled into a ball when the nose dug into marsh ground at 60mph, flare wasn't an option due to power lines. If Ace hadn't fitted a full harness belt setup I wouldn't be typing this today...

    ACE redrives for most commercial engines.

    After the experience of rather more than a mere 'hard landing' (trike nose dug in marshy ground at 60mph and rolled into a ball, if Ace didn't fit full harness restraints this conversation would be ongoing) I hauled the pieces home and retrieved few usable items. The motor had lunched itself...

    ACE redrives for most commercial engines.

    No commercial connection at all; John is a friend, I don't like bullying with inappropriate questions that cause him commercial damage; Indian manufacture was mentioned, ignoring that it was supervised by a Brit, which triggered my racism detector, would that be mentioned if it was German...

    ACE redrives for most commercial engines.

    Oil cooler radiator is fine at standard size, recommend unbolting it from the casing (vibration can crack the bracket) and mount it on fabric reinforced rubber strip hanging out to the side, the stock case has leak holes to blow fan air through the radiator but I blocked those to give max air to...

    ACE redrives for most commercial engines.

    First off cooling:- Tests were made directly above an airfield with multiple runways in case things went bang. The Briggs chosen is not the common USA red cowled version but the deeper fan/black cowl that the Japanese introduced; mine was from Europe. Have photos of the two versions after...

    ACE redrives for most commercial engines.

    Encountered many such repeat queries in thirty years of structural design; the questioner will just lazily bat this back no matter what information Ace Aviation provide, there's a sad aspect to human nature that enjoys watching folk jump around as they tug their leash, and waste a busy (and...

    22 Hp Harbor Freight engine evaluation + other V tiwns

    Yes, I've designed one and so far it fits every SAE bolt pattern from Briggs, Kohler etc. Ace Aviation in India machines them up and have made over fifty now worldwide. Stripped the motor last week to balance the crank and no visible wear or problems at 130+ hours Cheers Kev, UK

    What do you think of this engine?

    Posted on this elswhere so if you have read it, apologies. You guys in the USA are lucky, plenty of people converting for a big maket, the Valley reduction looked a little crude for my purposes so sat down on the CAD and drew up one to fit the small block B&S Vanguard, it was machined up by Ace...

    Ace Aviation & Engineering PSRUs for industrial V-twin engines

    Thanks Dino When you install in something like a Quickie, you can either fit the plate 'prop low' so the cylinders stick up out into the breeze, or drop the engine down 'prop high' as I've done to hide them inside the cowl. Prop high on a weightshift gives a lower CofG, via a lower engine...

    Ace Aviation & Engineering PSRUs for industrial V-twin engines

    Hi all The reduction drive was designed on CAD at my engineering business in England, John requested the back-plate have extra holes and extended plate so it could also suit free air cooled tractor aircraft 16 revisions, several prototypes and a lot of feedback later and it weighs 3.89 kilos...

    Industrial V-Twins

    Looked at the Valley reduction and it looks crudely made and heavy, mine is just 3.89 kilos or 8 pounds 9 ounces and was machined up by a British friend in his Indian factory for $590 plus carriage. He now sells them worldwide for fitting to any industrial engine and he can play with pulley...
